In most states and in all Canadian provinces, thelaw says to wear safety belts. Here is why:They work.

You never know if you will be in a crash. If you dohave a crash, you do not know if it will be abad one.

A few crashes are mild, and some crashes can beso serious that even buckled up, a personwould not survive. But most crashes are inbetween. In many of them, people who buckle upcan survive and sometimes walk away. Withoutbelts they could have been badly hurt or killed.

After more than 40 years of safety belts invehicles, the facts are clear. In most crashesbuckling up does matter... a lot!

Why Safety Belts WorkWhen you ride in or on anything, you go as fastas it goes.

Take the simplest vehicle. Suppose it is just aseat on wheels.

With safety belts, you slow down as the vehicledoes. You get more time to stop. You stopover more distance, and your strongest bonestake the forces. That is why safety beltsmake such good sense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicle after anaccident if I am wearing a safety belt?

A: You could be — whether you are wearing asafety belt or not. But you can unbuckle asafety belt, even if you are upside down. Andyour chance of being conscious during andafter an accident, so you can unbuckle and getout, is much greater if you are belted.

Q: If my vehicle has airbags, why should Ihave to wear safety belts?

A: Airbags are supplemental systems only; sothey work with safety belts — not instead ofthem. Every airbag system ever offeredfor sale has required the use of safety belts.Even if you are in a vehicle that has airbags,you still have to buckle up to get the mostprotection. That is true not only in frontalcollisions, but especially in side and othercollisions.

Q: If I am a good driver, and I never drive farfrom home, why should I wear safety belts?

A: You may be an excellent driver, but if you arein an accident — even one that is not yourfault — you and your passengers can be hurt.Being a good driver does not protect youfrom things beyond your control, such as baddrivers.

Most accidents occur within 25 miles (40 km)of home. And the greatest number ofserious injuries and deaths occur at speedsof less than 40 mph (65 km/h).

4. Push the latch plate into the buckle untilit clicks.Pull up on the latch plate to make sure itis secure. If the belt is not long enough, seeSafety Belt Extender on page 39.Make sure the release button on the buckle ispositioned so you would be able to unbucklethe safety belt quickly if you ever had to.

6. To make the lap part tight, pull up on theshoulder belt.It may be necessary to pull stitching on thesafety belt through the latch plate to fullytighten the lap belt on smaller occupants.

The lap part of the belt should be worn low andsnug on the hips, just touching the thighs. In acrash, this applies force to the strong pelvic bones.And you would be less likely to slide under the lapbelt. If you slid under it, the belt would apply force atyour abdomen. This could cause serious or evenfatal injuries. The shoulder belt should go over theshoulder and across the chest. These parts of thebody are best able to take belt restraining forces.The safety belt locks if there is a sudden stopor crash.

The right front passenger’s safety belt works thesame way as the driver’s safety belt — exceptfor one thing. If you ever pull the shoulder portionof the belt out all the way, you will engage thechild restraint locking feature which may turn offthe passenger’s frontal airbag. If this happens, justlet the belt go back all the way and start again.

The lap part of the belt should be worn low andsnug on the hips, just touching the thighs. Ina crash, this applies force to the strong pelvicbones. And you would be less likely to slide underthe lap belt. If you slid under it, the belt wouldapply force at your abdomen. This could causeserious or even fatal injuries.

The shoulder belt should go over the shoulder andacross the chest. These parts of the body arebest able to take belt restraining forces.

The safety belt locks if there is a sudden stop ora crash.

{CAUTION:

You can be seriously hurt if your shoulderbelt is too loose. In a crash, you wouldmove forward too much, which couldincrease injury. The shoulder belt shouldfit against your body.

Safety Belt PretensionersYour vehicle has safety belt pretensioners for thedriver and right front passenger. Although youcannot see them, they are part of the safety beltassembly. They help tighten the safety belts duringthe early stages of a moderate to severe frontaland near frontal crash if the threshold conditionsfor pretensioner activation are met. And, ifyour vehicle has side impact airbags, safety beltpretensioners can help tighten the safety belts ina side crash.

Pretensioners work only once. If they activatein a crash, you will need to get new ones,and probably other new parts for your safety beltsystem. See Replacing Restraint System PartsAfter a Crash on page 83.

Safety Belt ExtenderIf the vehicle’s safety belt will fasten around you,you should use it.

But if a safety belt is not long enough, your dealerwill order you an extender. When you go in toorder it, take the heaviest coat you will wear, sothe extender will be long enough for you. Tohelp avoid personal injury, do not let someone elseuse it, and use it only for the seat it is made tofit. The extender has been designed for adults.Never use it for securing child seats. To wear it,just attach it to the regular safety belt. Formore information see the instruction sheet thatcomes with the extender.

Child Restraints

Older Children

Older children who have outgrown booster seatsshould wear the vehicle’s safety belts.

Q: What is the proper way to wear safety belts?

A: An older child should wear a lap-shoulder beltand get the additional restraint a shoulder beltcan provide. The shoulder belt should notcross the face or neck. The lap belt should fitsnugly below the hips, just touching thetop of the thighs. It should never be worn overthe abdomen, which could cause severe oreven fatal internal injuries in a crash.

According to accident statistics, children are saferwhen properly restrained in the rear seatingpositions than in the front seating positions.

In a crash, children who are not buckled up canstrike other people who are buckled up, or can bethrown out of the vehicle. Older children needto use safety belts properly.

{CAUTION:

Never do this.

Here two children are wearing the samebelt. The belt can not properly spread theimpact forces. In a crash, the two childrencan be crushed together and seriouslyinjured. A belt must be used by onlyone person at a time.

Q: What if a child is wearing a lap-shoulderbelt, but the child is so small that theshoulder belt is very close to the child’sface or neck?

A: If the child is sitting in a seat next to awindow, move the child toward the centerof the vehicle. Also see Rear Safety BeltComfort Guides on page 36. If the child issitting in the center rear seat passengerposition, move the child toward the safetybelt buckle. In either case, be sure thatthe shoulder belt still is on the child’s shoulder,so that in a crash the child’s upper bodywould have the restraint that belts provide.

41

{CAUTION:

Never do this.

Here a child is sitting in a seat that has alap-shoulder belt, but the shoulder part isbehind the child. If the child wears thebelt in this way, in a crash the child mightslide under the belt. The belt’s forcewould then be applied right on the child’sabdomen. That could cause serious orfatal injuries.

Wherever the child sits, the lap portion of the beltshould be worn low and snug on the hips, justtouching the child’s thighs. This applies belt forceto the child’s pelvic bones in a crash.

Infants and Young ChildrenEveryone in a vehicle needs protection! Thisincludes infants and all other children. Neither thedistance traveled nor the age and size of thetraveler changes the need, for everyone, to usesafety restraints. In fact, the law in every statein the United States and in every Canadianprovince says children up to some age must berestrained while in a vehicle.

{CAUTION:

Children can be seriously injured orstrangled if a shoulder belt is wrappedaround their neck and the safety beltcontinues to tighten. Never leave childrenunattended in a vehicle and never allowchildren to play with the safety belts.

Every time infants and young children ride invehicles, they should have the protection providedby appropriate restraints. Young children shouldnot use the vehicle’s adult safety belts alone,unless there is no other choice. Instead, theyneed to use a child restraint.

{CAUTION:

People should never hold a baby in theirarms while riding in a vehicle. A babydoes not weigh much — until a crash.During a crash a baby will becomeso heavy it is not possible to hold it.For example, in a crash at only 25 mph(40 km/h), a 12 lb (5.5 kg) baby willsuddenly become a 240 lb (110 kg) forceon a person’s arms. A baby should besecured in an appropriate restraint.

{CAUTION:

Children who are up against, or veryclose to, any airbag when it inflates canbe seriously injured or killed. Airbagsplus lap-shoulder belts offer protectionfor adults and older children, but notfor young children and infants. Neither thevehicle’s safety belt system nor its airbagsystem is designed for them. Youngchildren and infants need the protectionthat a child restraint systemcan provide.

Q: What are the different types of add-onchild restraints?

A: Add-on child restraints, which are purchased bythe vehicle’s owner, are available in four basictypes. Selection of a particular restraint shouldtake into consideration not only the child’sweight, height, and age but also whether or notthe restraint will be compatible with the motorvehicle in which it will be used.

For most basic types of child restraints, thereare many different models available. Whenpurchasing a child restraint, be sure it isdesigned to be used in a motor vehicle. If it is,the restraint will have a label saying that itmeets federal motor vehicle safety standards.

The restraint manufacturer’s instructionsthat come with the restraint state the weightand height limitations for a particular childrestraint. In addition, there are many kinds ofrestraints available for children withspecial needs.

{CAUTION:

Newborn infants need complete support,including support for the head and neck.This is necessary because a newborninfant’s neck is weak and its head weighsso much compared with the rest of itsbody. In a crash, an infant in a rear-facingseat settles into the restraint, so thecrash forces can be distributed acrossthe strongest part of an infant’s body,the back and shoulders. Infants alwaysshould be secured in appropriate infantrestraints.

46

{CAUTION:

The body structure of a young child isquite unlike that of an adult or older child,for whom the safety belts are designed.A young child’s hip bones are still sosmall that the vehicle’s regular safety beltmay not remain low on the hip bones, asit should. Instead, it may settle up aroundthe child’s abdomen. In a crash, the beltwould apply force on a body area that isunprotected by any bony structure. Thisalone could cause serious or fatal injuries.Young children always should be securedin appropriate child restraints.

Child Restraint Systems

An infant car bed (A), a special bed made for usein a motor vehicle, is an infant restraint systemdesigned to restrain or position a child on acontinuous flat surface. Make sure that the infant’shead rests toward the center of the vehicle.

47

Page 48: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

A rear-facing infant seat (B) provides restraint withthe seating surface against the back of theinfant. The harness system holds the infant inplace and, in a crash, acts to keep the infantpositioned in the restraint.

A forward-facing child seat (C-E) provides restraintfor the child’s body with the harness and alsosometimes with surfaces such as T-shapedor shelf-like shields.

A booster seat (F-G) is a child restraint designedto improve the fit of the vehicle’s safety beltsystem. Some booster seats have a shoulder beltpositioner, and some high-back booster seatshave a five-point harness. A booster seat canalso help a child to see out the window.

Q: How Should I Use a Child Restraint?

A: A child restraint system is any device designedfor use in a motor vehicle to restrain, seat, orposition children. A built-in child restraintsystem is a permanent part of the motorvehicle. An add-on child restraint system is aportable one, which is purchased by thevehicle’s owner. To help reduce injuries, anadd-on child restraint must be secured inthe vehicle. With built-in or add-on childrestraints, the child has to be secured withinthe child restraint.

When choosing an add-on child restraint, besure the child restraint is designed to beused in a vehicle. If it is, it will have a labelsaying that it meets federal motor vehiclesafety standards. Then follow the instructionsfor the restraint. You may find theseinstructions on the restraint itself or in abooklet, or both.

Securing an Add-on Child Restraintin the Vehicle

{CAUTION:

A child can be seriously injured or killedin a crash if the child restraint is notproperly secured in the vehicle. Makesure the child restraint is properlyinstalled in the vehicle using the vehicle’ssafety belt or LATCH system, followingthe instructions that came with thatrestraint, and also the instructions inthis manual.

To help reduce the chance of injury, the childrestraint must be secured in the vehicle. Childrestraint systems must be secured in vehicle seatsby lap belts or the lap belt portion of a lap-shoulderbelt, or by the LATCH system.

See Lower Anchors and Tethers for Children(LATCH) on page 53 for more information.A child can be endangered in a crash if the childrestraint is not properly secured in the vehicle.

When securing an add-on child restraint, referto the instructions that come with the restraintwhich may be on the restraint itself or in a booklet,or both, and to this manual. The child restraintinstructions are important, so if they are notavailable, obtain a replacement copy from themanufacturer.

Keep in mind that an unsecured child restraint canmove around in a collision or sudden stop andinjure people in the vehicle. Be sure to properlysecure any child restraint in your vehicle — evenwhen no child is in it.

Securing the Child Within the ChildRestraintThere are several systems for securing the childwithin the child restraint. One system, thethree-point harness, has straps that come downover each of the infant’s shoulders and buckletogether at the crotch. The five-point harnesssystem has two shoulder straps, two hip straps,and a crotch strap. A shield may take the place ofhip straps. A T-shaped shield has shoulder strapsthat are attached to a flat pad which rests lowagainst the child’s body. A shelf- or armrest-typeshield has straps that are attached to a wide,shelf-like shield that swings up or to the side.

{CAUTION:

A child can be seriously injured or killedin a crash if the child is not properlysecured in the child restraint. Make surethe child is properly secured, following theinstructions that came with that restraint.

Because there are different systems, it is importantto refer to the instructions that come with therestraint. A child can be endangered in a crash ifthe child is not properly secured in the childrestraint.

Where to Put the RestraintAccident statistics show that children are safer ifthey are restrained in the rear rather than the frontseat. We recommend that child restraints besecured in a rear seat, including an infant ridingin a rear-facing infant seat, a child riding in aforward-facing child seat and an older child ridingin a booster seat.

Your vehicle has a rear seat that will accommodatea rear-facing child restraint. A label on your sunvisor says, “Never put a rear-facing child seatin the front.” This is because the risk to therear-facing child is so great, if the airbag deploys.

{CAUTION:

A child in a rear-facing child restraint canbe seriously injured or killed if the rightfront passenger’s airbag inflates. This isbecause the back of the rear-facing childrestraint would be very close to theinflating airbag.

Your vehicle may have a passengersensing system that is designed to turnoff the passenger’s frontal airbag if thesystem detects a rear-facing childrestraint. However, no system is fail-safe,

CAUTION: (Continued)

CAUTION: (Continued)

and no one can guarantee that an airbagwill not deploy under some unusualcircumstance, even though it is turned off.We recommend that rear-facing childrestraints be secured in the rear seat,even if the airbag is off.

If you need to secure a forward-facingchild restraint in the right front seat,always move the front passenger seat asfar back as it will go. It is better to securethe child restraint in a rear seat.

Wherever you install a child restraint, be sure tosecure the child restraint properly.

Keep in mind that an unsecured child restraint canmove around in a collision or sudden stop andinjure people in the vehicle. Be sure to properlysecure any child restraint in your vehicle — evenwhen no child is in it.

Lower Anchors and Tethers forChildren (LATCH)The LATCH system holds a child restraint duringdriving or in a crash. This system is designedto make installation of a child restraint easier. TheLATCH system uses anchors in the vehicle andattachments on the child restraint that are made foruse with the LATCH system

Make sure that a LATCH-compatible child restraintis properly installed using the anchors, or usethe vehicle’s safety belts to secure the restraint,following the instructions that came with thatrestraint, and also the instructions in this manual.When installing a child restraint with a toptether, you must also use either the lower anchorsor the safety belts to properly secure the childrestraint. A child restraint must never be installedusing only the top tether and anchor.

In order to use the LATCH system in your vehicle,you need a child restraint that has LATCHattachments. The child restraint manufacturer willprovide you with instructions on how to usethe child restraint and its attachments. Thefollowing explains how to attach a child restraintwith these attachments in your vehicle.

Not all vehicle seating positions or child restraintshave lower anchors and attachments or toptether anchors and attachments.

Lower Anchors

Lower anchors (A) are metal bars built into thevehicle. There are two lower anchors for eachLATCH seating position that will accommodate achild restraint with lower attachments (B).

53

Page 54: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Top Tether Anchor

A top tether (A, C) anchors the top of the childrestraint to the vehicle. A top tether anchor is builtinto the vehicle. The top tether attachment (B)on the child restraint connects to the top tetheranchor in the vehicle in order to reduce the forwardmovement and rotation of the child restraintduring driving or in a crash.

Your child restraint may have a single tether (A)or a dual tether (C). Either will have a singleattachment (B) to secure the top tether tothe anchor.

Some child restraints that have a top tether aredesigned for use with or without the top tetherbeing attached. Others require the top tetheralways to be attached. In Canada, the law requiresthat forward-facing child restraints have a toptether, and that the tether be attached. Inthe United States, some child restraints also havea top tether. Be sure to read and follow theinstructions for your child restraint.

If the child restraint does not have a top tether,one can be obtained, in kit form, for manychild restraints. Ask the child restraintmanufacturer whether or not a kit is available.

Securing a Child Restraint in theRight Front Seat PositionYour vehicle has a right front passenger’sairbag. A rear seat is a safer place to secure aforward-facing child restraint. See Where toPut the Restraint on page 51.In addition, if your vehicle has a passenger airbagstatus indicator, your vehicle has the passengersensing system. The passenger sensing system isdesigned to turn off the right front passenger’sfrontal airbag when an infant in a rear-facinginfant seat or a small child in a forward-facingchild restraint or booster seat is detected.See Passenger Airbag Status Indicator onpage 164 for more information on this includingimportant safety information.If your vehicle does not have the passenger sensingsystem, the right front passenger’s frontal airbagwill deploy in collisions that are severe enough todeploy the frontal airbags, even if an infant or asmall child is in the right front passenger’s seat.A label on your sun visor says, “Never put arear-facing child seat in the front.” This is becausethe risk to the rear-facing child is so great, if theairbag deploys.

{CAUTION:

A child in a rear-facing child restraint canbe seriously injured or killed if the rightfront passenger’s airbag inflates. This isbecause the back of the rear-facing childrestraint would be very close to theinflating airbag.

Your vehicle may have a passengersensing system that is designed to turnoff the passenger’s frontal airbag if thesystem detects a rear-facing childrestraint. However, no system is fail-safe,and no one can guarantee that an airbagwill not deploy under some unusualcircumstance, even though it is turned off.We recommend that rear-facing childrestraints be secured in the rear seat,even if the airbag is off.

6. To tighten the belt, push down on the childrestraint, pull the shoulder portion of the beltto tighten the lap portion of the belt, andfeed the shoulder belt back into the retractor.If you are using a forward-facing childrestraint, you may find it helpful to use yourknee to push down on the child restraintas you tighten the belt. You should not be ableto pull more of the belt from the retractoronce the lock has been set.

7. Push and pull the child restraint in differentdirections to be sure it is secure.

8. If your vehicle has a passenger sensingsystem and the airbag is off, the off indicatoron the instrument panel will be lit and staylit when the key is turned to RUN or START.

If a child restraint has been installed and the onindicator is lit, turn the vehicle off. Removethe child restraint from the vehicle and reinstall thechild restraint.

If, after reinstalling the child restraint and restartingthe vehicle, the on indicator is still lit, check tomake sure that the vehicle’s seatback is notpressing the child restraint into the seat cushion.If this happens, slightly recline the vehicle’sseatback and adjust the seat cushion if possible.Also make sure the child restraint is not trappedunder the vehicle head restraint. If this happens,adjust the head restraint.

If the on indicator is still lit, secure the child inthe child restraint in a rear seat position inthe vehicle and check with your dealer.

To remove the child restraint, just unbuckle thevehicle’s safety belt and let it go back all the way.The safety belt will move freely again and beready to work for an adult or larger childpassenger.

Airbag SystemYour vehicle has a frontal airbag for the driver anda frontal airbag for the right front passenger.Your vehicle may also have roof-mounted sideimpact airbags. Roof-mounted side impact airbagsare available for the driver and the passengerseated directly behind the driver and for the rightfront passenger and the passenger seateddirectly behind that passenger.

If your vehicle has roof-mounted side impactairbags, the word AIRBAG will appear onthe airbag covering on the garnish trim near theceiling and the side windows.

Airbags are designed to supplement the protectionprovided by safety belts. Even though today’sairbags are also designed to help reduce the riskof injury from the force of an inflating bag, allairbags must inflate very quickly to do their job.

Here are the most important things to know aboutthe airbag system:

{CAUTION:

You can be severely injured or killed in acrash if you are not wearing your safetybelt — even if you have airbags. Wearingyour safety belt during a crash helpsreduce your chance of hitting thingsinside the vehicle or being ejected from it.Airbags are “supplemental restraints” tothe safety belts. All airbags are designedto work with safety belts but do notreplace them.

CAUTION: (Continued)

66

CAUTION: (Continued)

Frontal airbags for the driver and rightfront passenger are designed to deploy inmoderate to severe frontal and nearfrontal crashes. They are not designed toinflate in rollover, rear crashes, or in manyside crashes. And, for some unrestrainedoccupants, frontal airbags may provideless protection in frontal crashes thanmore forceful airbags have provided inthe past.

Roof-mounted side impact airbags aredesigned to inflate in moderate to severecrashes where something hits the side ofyour vehicle. They are not designed toinflate in frontal, in rollover or in rearcrashes. Everyone in your vehicle shouldwear a safety belt properly — whether ornot there is an airbag for that person.

{CAUTION:

Both frontal and side impact airbagsinflate with great force, faster than theblink of an eye. If you are too close to aninflating airbag, as you would be if youwere leaning forward, it could seriouslyinjure you. Safety belts help keep you inposition for airbag inflation before andduring a crash. Always wear your safetybelt even with frontal airbags. The drivershould sit as far back as possible whilestill maintaining control of the vehicle.Occupants should not lean on or sleepagainst the door.

{CAUTION:

Anyone who is up against, or very closeto, any airbag when it inflates can beseriously injured or killed. Airbags pluslap-shoulder belts offer the bestprotection for adults, but not for youngchildren and infants. Neither the vehicle’ssafety belt system nor its airbag system isdesigned for them. Young children andinfants need the protection that a childrestraint system can provide. Alwayssecure children properly in your vehicle.To read how, see Older Children onpage 40 or Infants and Young Childrenon page 43.

There is an airbagreadiness light on theinstrument panel cluster,which shows theairbag symbol.

The system checks the airbag electrical systemfor malfunctions. The light tells you if there isan electrical problem. See Airbag Readiness Lighton page 163 for more information.

Where Are the Airbags?

The driver’s frontal airbag is in the middle of thesteering wheel.

The right front passenger’s frontal airbag is in theinstrument panel on the passenger’s side.

If your vehicle has a roof-mounted side impactairbag for the driver and the person seated directlybehind the driver, it is located in the ceilingabove the side windows.

If your vehicle has a roof-mounted side impactairbag for the right front passenger and the persondirectly behind that passenger, it is located inthe ceiling above the side windows.

{CAUTION:

If something is between an occupant andan airbag, the bag might not inflateproperly or it might force the object intothat person causing severe injury or evendeath. The path of an inflating airbag mustbe kept clear. Do not put anythingbetween an occupant and an airbag, anddo not attach or put anything on thesteering wheel hub or on or near anyother airbag covering. And, if your vehiclehas roof-mounted side impact airbags,never secure anything to the roof of yourvehicle by routing the rope or tie downthrough any door or window opening. Ifyou do, the path of an inflating sideimpact airbag will be blocked. The path ofan inflating airbag must be kept clear.

When Should an Airbag Inflate?The driver’s and right front passenger’s frontalairbags are designed to inflate in moderate tosevere frontal or near-frontal crashes. But they aredesigned to inflate only if the impact exceeds apredetermined deployment threshold. Deploymentthresholds take into account a variety of desireddeployment and non-deployment events and areused to predict how severe a crash is likely to be intime for the airbags to inflate and help restrain theoccupants. Whether your frontal airbags will orshould deploy is not based on how fast your vehicleis traveling. It depends largely on what you hit, thedirection of the impact and how quickly your vehicleslows down.

In addition, your vehicle has “dual-stage” frontalairbags, which adjust the restraint accordingto crash severity. Your vehicle has an electronicfrontal sensor which helps the sensing systemdistinguish between a moderate frontal impactand a more severe frontal impact. For moderatefrontal impacts, these airbags inflate at a level lessthan full deployment. For more severe frontalimpacts, full deployment occurs.

71

Page 72: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

If the front of your vehicle goes straight into awall that does not move or deform, the thresholdlevel for the reduced deployment is about12 to 16 mph (19 to 26 km/h), and the thresholdlevel for a full deployment is about 18 to 24 mph(29 to 38.5 km/h). The threshold level canvary, however, with specific vehicle design, so thatit can be somewhat above or below this range.

Frontal airbags may inflate at different crashspeeds. For example:

• If the vehicle hits a stationary object, theairbags could inflate at a different crash speedthan if the vehicle hits a moving object.

• If the vehicle hits an object that deforms, theairbags could inflate at a different crashspeed than if the vehicle hits an object thatdoes not deform.

• If the vehicle hits a narrow object (like a pole)the airbags could inflate at a different crashspeed than if the vehicle hits a wide object(like a wall).

• If the vehicle goes into an object at an anglethe airbags could inflate at a different crashspeed than if the vehicle goes straight intothe object.

Frontal airbags (driver and right front passenger)are not intended to inflate during vehiclerollovers, rear impacts, or in many side impacts.

Your vehicle may or may not have roof-mountedside impact airbags. See Airbag System onpage 66. Roof-mounted side impact airbags areintended to inflate in moderate to severe sidecrashes. A roof-mounted side impact airbag willinflate if the crash severity is above the system’sdesigned threshold level. The threshold levelcan vary with specific vehicle design.Roof-mounted side impact airbags are notintended to inflate in frontal or near-frontal impacts,rollovers or rear impacts. A roof-mounted sideimpact airbag is intended to deploy on the side ofthe vehicle that is struck.

In any particular crash, no one can say whetheran airbag should have inflated simply becauseof the damage to a vehicle or because of what therepair costs were. For frontal airbags, inflation isdetermined by what the vehicle hits, the angleof the impact, and how quickly the vehicle slowsdown. For roof-mounted side impact airbags,inflation is determined by the location and severityof the impact.

What Makes an Airbag Inflate?In an impact of sufficient severity, the airbagsensing system detects that the vehicle isin a crash. The sensing system triggers a releaseof gas from the inflator, which inflates theairbag. The inflator, airbag, and related hardwareare all part of the airbag modules inside thesteering wheel and in the instrument panel in frontof the right front passenger. For vehicles withroof-mounted side impact airbags, there are alsoairbag modules in the ceiling of the vehicle,near the side windows.

How Does an Airbag Restrain?In moderate to severe frontal or near frontalcollisions, even belted occupants can contactthe steering wheel or the instrument panel.In moderate to severe side collisions, even beltedoccupants can contact the inside of the vehicle.Airbags supplement the protection providedby safety belts. Airbags distribute the force of theimpact more evenly over the occupant’s upperbody, stopping the occupant more gradually.

But the frontal airbags would not help you inmany types of collisions, including rollovers, rearimpacts, and many side impacts, primarily becausean occupant’s motion is not toward the airbag.Side impact airbags would not help you in manytypes of collisions, including many frontal ornear frontal collisions, rollovers, and rear impacts.

Airbags should never be regarded as anythingmore than a supplement to safety belts, andthen only in moderate to severe frontal ornear-frontal collisions for the driver’s and rightfront passenger’s frontal airbags, and onlyin moderate to severe side collisions for vehicleswith side impact airbags.

What Will You See After an AirbagInflates?After a frontal airbag inflates, it quickly deflates,so quickly that some people may not even realizethe airbag inflated. Roof-mounted side impactairbags may still be at least partially inflatedminutes after the vehicle comes to rest. Somecomponents of the airbag module — the steeringwheel hub for the driver’s airbag, the instrumentpanel for the right front passenger’s airbag, or thegarnish trim and ceiling of your vehicle nearthe side windows for vehicles with roof–mountedside impact airbags — may be hot for a short time.The parts of the airbag that come into contactwith you may be warm, but not too hot to touch.There may be some smoke and dust coming fromthe vents in the deflated airbags. Airbag inflationdoes not prevent the driver from seeing out of thewindshield or being able to steer the vehicle,nor does it prevent people from leaving the vehicle.

{CAUTION:

When an airbag inflates, there may bedust in the air. This dust could causebreathing problems for people with ahistory of asthma or other breathingtrouble. To avoid this, everyone in thevehicle should get out as soon as it issafe to do so. If you have breathingproblems but cannot get out of the vehicleafter an airbag inflates, then get fresh airby opening a window or a door. If youexperience breathing problems followingan airbag deployment, you should seekmedical attention.

Your vehicle has a feature that may automaticallyunlock the doors, turn the interior lamps on, andturn the hazard warning flashers when the airbagsinflate. You can lock the doors again, turn theinterior lamps off, and turn the hazard warningflashers off by using the controls for those features.

In many crashes severe enough to inflate an airbag,windshields are broken by vehicle deformation.Additional windshield breakage may also occurfrom the right front passenger airbag.

• Airbags are designed to inflate only once.After an airbag inflates, you will need some newparts for the airbag system. If you do not getthem, the airbag system will not be there to helpprotect you in another crash. A new system willinclude airbag modules and possibly otherparts. The service manual for your vehiclecovers the need to replace other parts.

• Your vehicle has a crash sensing anddiagnostic module which records informationafter a crash. See Vehicle Data Collectionand Event Data Recorders on page 422.

• Let only qualified technicians work on theairbag system. Improper service can meanthat your airbag system will not work properly.See your dealer for service.

Passenger Sensing SystemIf your vehicle has one of the indicators pictured inthe following illustrations, then your vehicle hasa passenger sensing system for the right frontpassenger’s position. A passenger airbag statusindicator on the instrument panel will be visiblewhen you turn your ignition key to START or RUN.

The words ON and OFF, or the symbol forON and OFF, will be visible on the instrumentpanel during the system check. When the systemcheck is complete, either the word ON or theword OFF, or the symbol for ON or the symbolfor OFF will be visible. See Passenger AirbagStatus Indicator on page 164.

The passenger sensing system will turn off theright front passenger’s frontal airbag under certainconditions. The driver’s airbags are not part ofthe passenger sensing system.

The passenger sensing system works withsensors that are part of the right front passenger’sseat and safety belt. The sensors are designedto detect the presence of a properly-seatedoccupant and determine if the passenger’s frontalairbag should be enabled (may inflate) or not.

Accident statistics show that children are saferif they are restrained in the rear rather thanthe front seat. We recommend that child restraintsbe secured in a rear seat, including an infantriding in a rear-facing infant seat, a child riding ina forward-facing child seat and an older childriding in a booster seat.

Your vehicle has a rear seat that will accommodatea rear-facing child restraint. A label on your sunvisor says, “Never put a rear-facing child seatin the front.” This is because the risk to therear-facing child is so great, if the airbag deploys.

{CAUTION:

A child in a rear-facing child restraint canbe seriously injured or killed if the rightfront passenger’s airbag inflates. This isbecause the back of the rear-facing childrestraint would be very close to theinflating airbag.

Your vehicle may have a passengersensing system that is designed to turnoff the passenger’s frontal airbag if thesystem detects a rear-facing childrestraint. However, no system is fail-safe,and no one can guarantee that an airbagwill not deploy under some unusualcircumstance, even though it is turnedoff. We recommend that rear-facing childrestraints be secured in the rear seat,even if the airbag is off.

CAUTION: (Continued)

CAUTION: (Continued)

If you need to secure a forward-facingchild restraint in the right front seat,always move the front passenger seat asfar back as it will go. It is better to securethe child restraint in a rear seat.

The passenger sensing system is designed to turnoff the right front passenger’s frontal airbag if:• The right front passenger seat is unoccupied.• The system determines that an infant is

present in a rear-facing infant seat.• The system determines that a small child is

present in a forward-facing child restraint.• The system determines that a small child is

present in a booster seat.• A right front passenger takes his/her weight off

of the seat for a period of time.• The right front passenger seat is occupied by

a smaller person, such as a child who hasoutgrown child restraints.

• Or, if there is a critical problem with the airbagsystem or the passenger sensing system.

When the passenger sensing system has turnedoff the passenger’s frontal airbag, the off indicatoron the instrument panel will light and stay lit toremind you that the airbag is off.

If a child restraint has been installed and the onindicator is lit, turn the vehicle off. Removethe child restraint from the vehicle and reinstallthe child restraint following the child restraintmanufacturer’s directions and refer to Securing aChild Restraint in the Right Front Seat Positionon page 62.

If, after reinstalling the child restraint and restartingthe vehicle, the on indicator is still lit, check tomake sure that the vehicle’s seatback is notpressing the child restraint into the seat cushion.If this happens, slightly recline the vehicle’sseatback and adjust the seat cushion if possible.Also make sure the child restraint is not trappedunder the vehicle head restraint. If this happens,adjust the head restraint.

If the on indicator is still lit, secure the child inthe child restraint in a rear seat position inthe vehicle and check with your dealer.

The passenger sensing system is designed toenable (may inflate) the right front passenger’sfrontal airbag anytime the system sensesthat a person of adult size is sitting properly in theright front passenger’s seat. When the passengersensing system has allowed the airbag to beenabled, the on indicator will light and stay lit toremind you that the airbag is active.

For some children who have outgrown childrestraints and for very small adults, the passengersensing system may or may not turn off theright front passenger’s frontal airbag, dependingupon the person’s seating posture and body build.Everyone in your vehicle who has outgrownchild restraints should wear a safety beltproperly — whether or not there is an airbagfor that person.

If a person of adult-size is sitting in the rightfront passenger’s seat, but the off indicator islit, it could be because that person is not sittingproperly in the seat. If this happens, turn thevehicle off and ask the person to place theseatback in the fully upright position, then situpright in the seat, centered on the seat cushion,with the person’s legs comfortably extended.

Restart the vehicle and have the person remainin this position for about two minutes. Thiswill allow the system to detect that person andthen enable the passenger’s airbag.

If your vehicle does not have the passengersensing system, the right front passenger’s frontalairbag will deploy in collisions that are severeenough to deploy the frontal airbags, regardlessof the size of the occupant in the right frontpassenger seat.

{CAUTION:

If the airbag readiness light in theinstrument panel cluster ever comes onand stays on, it means that somethingmay be wrong with the airbag system.If this ever happens, have the vehicleserviced promptly, because an adult-sizeperson sitting in the right frontpassenger’s seat may not have theprotection of the frontal airbag. SeeAirbag Readiness Light on page 163 formore on this, including important safetyinformation.

Aftermarket equipment, such as seat covers, canaffect how well the passenger sensing systemoperates. You may want to consider not using seatcovers or other aftermarket equipment if yourvehicle has the passenger sensing system. SeeAdding Equipment to Your Airbag-EquippedVehicle on page 81 for more information aboutmodifications that can affect how the systemoperates.

{CAUTION:

Stowing of articles under the passenger’sseat or between the passenger’s seatcushion and seatback may interfere withthe proper operation of the passengersensing system.

Servicing Your Airbag-EquippedVehicleAirbags affect how your vehicle should beserviced. There are parts of the airbag system inseveral places around your vehicle. You donot want the system to inflate while someone isworking on your vehicle. Your dealer and theservice manual have information about servicingyour vehicle and the airbag system. To purchasea service manual, see Service PublicationsOrdering Information on page 429.

{CAUTION:

For up to 10 seconds, after the ignition isturned off and the battery is disconnected,an airbag can still inflate during improperservice. You can be injured if you areclose to an airbag when it inflates. Avoidyellow connectors. They are probably partof the airbag system. Be sure to followproper service procedures, and make surethe person performing work for you isqualified to do so.

The airbag system does not need regularmaintenance.

Adding Equipment to YourAirbag-Equipped Vehicle

Q: Is there anything I might add to the frontor sides of the vehicle that could keep theairbags from working properly?

A: Yes. If you add things that change yourvehicle’s frame, bumper system, height,front end or side sheet metal, they may keepthe airbag system from working properly.Also, the airbag system may not work properlyif you relocate any of the airbag sensors.If you have any questions about this,you should contact Customer Assistancebefore you modify your vehicle. The phonenumbers and addresses for CustomerAssistance are in Step Two of the CustomerSatisfaction Procedure in this manual.See Customer Satisfaction Procedureon page 410.

Q: Because I have a disability, I have to getmy vehicle modified. How can I find outwhether this will affect my airbag system?

A: Changing or moving any parts of thefront seats, safety belts, the airbag sensingand diagnostic module, steering wheel,instrument panel, ceiling headliner, ceilingand pillar garnish trim, roof-mounted airbagmodules, or airbag wiring can affect theoperation of the airbag system. If you havequestions, call Customer Assistance. Thephone numbers and addresses for CustomerAssistance are in Step Two of the CustomerSatisfaction Procedure in this manual.See Customer Satisfaction Procedureon page 410.

Restraint System Check

Checking the Restraint SystemsNow and then, make sure the safety belt reminderlight and all your belts, buckles, latch plates,retractors and anchorages are working properly.Look for any other loose or damaged safetybelt system parts. If you see anything that mightkeep a safety belt system from doing its job,have it repaired. See Care of Safety Beltson page 372 for more information.

Torn or frayed safety belts may not protect you ina crash. They can rip apart under impact forces.If a belt is torn or frayed, get a new one right away.

Also look for any opened or broken airbagcovers, and have them repaired or replaced.The airbag system does not need regularmaintenance.

Notice: If you damage the covering for thedriver’s or the right front passenger’s airbag,or the roof-mounted side impact airbagcovering (if equipped) on the garnish trim andceiling near the side windows, the airbagmay not work properly. You may have toreplace the airbag module in the steeringwheel, both the airbag module and theinstrument panel for the right front passenger’sairbag, or the side impact airbag module,garnish trim and the ceiling covering forroof-mounted side impact airbags (if equipped).Do not open or break the airbag coverings.

Replacing Restraint System PartsAfter a Crash

{CAUTION:

A crash can damage the restraint systemsin your vehicle. A damaged restraintsystem may not properly protect theperson using it, resulting in serious injuryor even death in a crash. To help makesure your restraint systems are workingproperly after a crash, have them inspectedand any necessary replacements made assoon as possible.

If you have had a crash, do you need new belts orLATCH system parts?After a very minor collision, nothing may benecessary. But if the belts were stretched, as theywould be if worn during a more severe crash,then you need new parts.If the LATCH system was being used during amore severe crash, you may need new LATCHsystem parts.

If belts are cut or damaged, replace them.Collision damage also may mean you will need tohave LATCH system, safety belt or seat partsrepaired or replaced. New parts and repairs maybe necessary even if the belt or LATCH systemwas not being used at the time of the collision.

If an airbag inflates, you will need to replace airbagsystem parts. See the part on the airbag systemearlier in this section.

If the frontal airbags inflate you will also need toreplace the driver and front passenger’s safety beltretractor assembly. Be sure to do so. Then thenew retractor assembly will be there to help protectyou in a collision.

After a crash you may need to replace the driverand front passenger’s safety belt retractorassemblies, even if the frontal airbags have notdeployed. The driver and front passenger’s safetybelt retractor assemblies contain the safety beltpretensioners. Have your safety belt pretensionerschecked if your vehicle has been in a collision,or if your airbag readiness light stays on after youstart your vehicle or while you are driving. SeeAirbag Readiness Light on page 163.

Automatic TransaxleMove your shift lever to PARK (P) orNEUTRAL (N). Your engine will not start inany other position -- this is a safety feature.To restart when you are already moving, useNEUTRAL (N) only.

Notice: Shifting into PARK (P) with the vehiclemoving could damage the transaxle. Shift intoPARK (P) only when your vehicle is stopped.

Manual TransaxleThe shift lever should be in the neutral positionand the parking brake engaged. Hold theclutch pedal to the floor and start the engine. Yourvehicle will not start if the clutch pedal is not allthe way down. That is a safety feature.

Starting Procedure1. With your foot off the accelerator pedal, turn

the ignition key to START. When the enginestarts, let go of the key. The idle speed will godown as your engine gets warm. Do not racethe engine immediately after starting it.Operate the engine and transaxle gently toallow the oil to warm up and lubricate allmoving parts.Your vehicle has a Computer-ControlledCranking System. This feature assists instarting the engine and protects components.If the ignition key is turned to the STARTposition, and then released when the enginebegins cranking, the engine will continuecranking for a few seconds or until the vehiclestarts. If the engine does not start and the key isheld in START for many seconds, cranking willbe stopped after 15 seconds to preventcranking motor damage. To prevent geardamage, this system also prevents cranking ifthe engine is already running. Engine crankingcan be stopped by turning the ignition switch tothe ACC or LOCK position.

Notice: Cranking the engine for long periodsof time, by returning the key to the STARTposition immediately after cranking has ended,can overheat and damage the crankingmotor, and drain the battery. Wait at least15 seconds between each try, to allowthe cranking motor to cool down.

2. If the engine does not start after 5-10 seconds,especially in very cold weather (below 0°For −18°C), it could be flooded with too muchgasoline. Try pushing the acceleratorpedal all the way to the floor and holding itthere as you hold the key in START for up toa maximum of 15 seconds. Wait at least15 seconds between each try, to allow thecranking motor to cool down. When the enginestarts, let go of the key and accelerator.If the vehicle starts briefly but then stopsagain, do the same thing. This clears the extragasoline from the engine. Do not race theengine immediately after starting it. Operatethe engine and transaxle gently until theoil warms up and lubricates all moving parts.

Notice: Your engine is designed to work withthe electronics in your vehicle. If you addelectrical parts or accessories, you couldchange the way the engine operates. Beforeadding electrical equipment, check with yourdealer. If you do not, your engine might notperform properly. Any resulting damage wouldnot be covered by your vehicle’s warranty.

Engine Coolant HeaterYour vehicle may be equipped with an enginecoolant heater.

In very cold weather, 0°F (−18°C) or colder, theengine coolant heater can help. You will get easierstarting and better fuel economy during enginewarm-up.

Usually, the coolant heater should be plugged in aminimum of four hours prior to starting yourvehicle. At temperatures above 32°F (0°C), use ofthe coolant heater is not required. Your vehiclemay also have an internal thermostat in theplug end of the cord. This will prevent operation ofthe engine coolant heater when the temperatureis at or above 0°F (−18°C) as noted on the cord.

113

Page 114: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

To Use the Engine Coolant Heater1. Turn off the engine.

2. Open the hood and unwrap the electricalcord. For the 2.2L and 2.4L engines, theelectrical cord is located on the passenger’sside of the vehicle between the strut andthe air cleaner/filter.

3. Plug it into a normal, grounded110-volt AC outlet.

{CAUTION:

Plugging the cord into an ungroundedoutlet could cause an electrical shock.Also, the wrong kind of extension cordcould overheat and cause a fire. Youcould be seriously injured. Plug the cordinto a properly grounded three-prong110-volt AC outlet. If the cord will notreach, use a heavy-duty three-prongextension cord rated for at least 15 amps.

4. Before starting the engine, be sure to unplugand store the cord as it was before to keep itaway from moving engine parts. If you donot, it could be damaged.

How long should you keep the coolant heaterplugged in? The answer depends on the outsidetemperature, the kind of oil you have, andsome other things. Instead of trying to listeverything here, we ask that you contact aGM dealer in the area where you will be parkingyour vehicle. The dealer can give you the bestadvice for that particular area.

Automatic Transaxle OperationIf your vehicle has an automatic transaxle, theshift lever is located on the console betweenthe seats.

There are severaldifferent positions forthe automatic transaxle.

PARK (P): This position locks your front wheels.It is the best position to use when you startyour engine because your vehicle cannotmove easily.

{CAUTION:

It is dangerous to get out of your vehicleif the shift lever is not fully in PARK (P)with the parking brake firmly set. Yourvehicle can roll.

Do not leave your vehicle when the engineis running unless you have to. If you haveleft the engine running, the vehicle canmove suddenly. You or others could beinjured. To be sure your vehicle will notmove, even when you are on fairly levelground, always set your parking brakeand move the shift lever to PARK (P).See Shifting Into Park (P) (AutomaticTransaxle) on page 121. If you are pullinga trailer, see Towing a Trailer (ManualTransaxle) on page 261 or Towing aTrailer (Automatic Transaxle) on page 261.

Make sure the shift lever is fully in PARK (P)before starting the engine. Your vehicle has anautomatic transaxle shift lock control system.

115

Page 116: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

You have to fully apply your regular brakes firstand then press the shift lever button beforeyou can shift from PARK (P) when the ignition keyis in RUN. If you cannot shift out of PARK (P),ease pressure on the shift lever and push the shiftlever all the way into PARK (P) as you maintainbrake application. Then press the shift lever buttonand then move the shift lever into another gear.See Shifting Out of Park (P) (Automatic Transaxle)on page 123.

REVERSE (R): Use this gear to back up.

Notice: Shifting to REVERSE (R) while yourvehicle is moving forward could damage thetransaxle. The repairs would not be covered byyour warranty. Shift to REVERSE (R) only afteryour vehicle is stopped.To rock your vehicle back and forth to get out ofsnow, ice, or sand without damaging yourtransaxle, see If Your Vehicle is Stuck in Sand,Mud, Ice, or Snow on page 252.

NEUTRAL (N): In this position, your engine doesnot connect with the wheels. To restart whenyou are already moving, use NEUTRAL (N) only.Also, use NEUTRAL (N) when your vehicle isbeing towed.

{CAUTION:

Shifting into a drive gear while yourengine is running at high speed isdangerous. Unless your foot is firmly onthe brake pedal, your vehicle could movevery rapidly. You could lose control andhit people or objects. Do not shift into adrive gear while your engine is running athigh speed.

116

Page 117: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Notice: Shifting out of PARK (P) orNEUTRAL (N) while the engine is running athigh speed may damage the transaxle.The repairs would not be covered by yourwarranty. Be sure the engine is not running athigh speeds when shifting your vehicle.

DRIVE (D): This position is for normal driving withthe automatic transaxle. It provides the best fueleconomy for your vehicle. If you need more powerfor passing, and you are:

• Going less than about 35 mph (55 km/h), pushyour accelerator pedal about halfway down.

• Going about 35 mph (55 km/h), pushyour accelerator all the way down.

Downshifting the transaxle in slippery roadconditions could result in skidding, see “Skidding”under Loss of Control on page 236.

INTERMEDIATE (I): This position is also used fornormal driving. However, it reduces vehicle speedwithout using your brakes for slight downgradeswhere the vehicle would otherwise accelerate dueto steepness of grade. If constant upshifting ordownshifting occurs while driving up steep hills, thisposition can be used to prevent repetitive types ofshifts. You might choose INTERMEDIATE (I)instead of DRIVE (D) when driving on hilly, windingroads and when towing a trailer, so that there is lessshifting between gears.

LOW (L): This position reduces vehicle speedmore than INTERMEDIATE (I) without actuallyusing your brakes. You can use it on very steephills, or in deep snow or mud. If the shift leveris put in LOW (L), the transaxle will not shift intoLOW (L) until the vehicle is going slowly enough.

Notice: Spinning the tires or holding thevehicle in one place on a hill using only theaccelerator pedal may damage the transaxle. Ifyou are stuck, do not spin the tires. Whenstopping on a hill, use the brakes, or parkingbrake to hold the vehicle in place.

The battery can be discharged at idle if theelectrical loads are very high. This is true for allvehicles. This is because the generator (alternator)may not be spinning fast enough at idle toproduce all the power that is needed for very highelectrical loads.

A high electrical load occurs when several of thefollowing loads are on: headlamps, high beams,fog lamps, rear window defogger, climatecontrol fan at high speed, heated seats, enginecooling fans, trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessive discharge of thebattery. It does this by balancing the generator’soutput and the vehicle’s electrical needs. Itcan increase engine idle speed to generate morepower, whenever needed. It can temporarilyreduce the power demands of some accessories.

Normally, these actions occur in steps or levels,without being noticeable. In rare cases at thehighest levels of corrective action, this action maybe noticeable to the driver.

Battery Run-Down ProtectionYour vehicle has a battery saver feature designedto protect your vehicle’s battery.

When any interior lamp is left on and the ignitionis turned off, the battery rundown protectionsystem will automatically turn the lamp off after20 minutes. This will avoid draining the battery.

{CAUTION:

If the on indicator comes on when you havea rear-facing child restraint installed in theright front passenger’s seat, it means thatthe passenger sensing system has notturned off the passenger’s frontal airbag.A child in a rear-facing child restraint canbe seriously injured or killed if the rightfront passenger’s airbag inflates. This isbecause the back of the rear-facing childrestraint would be very close to theinflating airbag. Do not use a rear-facingchild restraint in the right front passenger’sseat if the airbag is turned on.

Your vehicle has a rear seat that will accommodatea rear-facing child restraint. A label on your sunvisor says, “Never put a rear-facing child seatin the front.” This is because the risk to therear-facing child is so great, if the airbag deploys.

{CAUTION:

Even though the passenger sensingsystem is designed to turn off thepassenger’s frontal airbag if the systemdetects a rear-facing child restraint, nosystem is failsafe, and no one canguarantee that an airbag will not deployunder some unusual circumstance, eventhough it is turned off. We recommendthat rear-facing child restraints be securedin the rear seat, even if the airbag is off.

If the word OFF or the off symbol is lit on theairbag status indicator, it means that thepassenger sensing system has turned off the rightfront passenger’s frontal airbag. See PassengerSensing System on page 75 for more on this,including important safety information.

If the Light is FlashingThe following may prevent more serious damageto your vehicle:

• Reducing vehicle speed

• Avoiding hard accelerations

• Avoiding steep uphill grades

• If you are towing a trailer, reduce the amount ofcargo being hauled as soon as it is possible

If the light stops flashing and remains on steady,see “If the Light Is On Steady” following.

If the light continues to flash, when it is safe to doso, stop the vehicle. Find a safe place to parkyour vehicle. Turn the key off, wait at least10 seconds and restart the engine. If the lightremains on steady, see “If the Light Is On Steady”following. If the light is still flashing, follow theprevious steps, and see your dealer for service assoon as possible.

If the Light Is On SteadyYou may be able to correct the emission systemmalfunction by considering the following:

Did you recently put fuel into your vehicle?

If so, reinstall the fuel cap, making sure to fullyinstall the cap. See Filling the Tank on page 280.The diagnostic system can determine if thefuel cap has been left off or improperly installed.A loose or missing fuel cap will allow fuel toevaporate into the atmosphere. A few driving tripswith the cap properly installed should turn thelight off.

Did you just drive through a deep puddle of water?

If so, your electrical system may be wet. Thecondition will usually be corrected when theelectrical system dries out. A few driving tripsshould turn the light off.

172

Page 173: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Have you recently changed brands of fuel?

If so, be sure to fuel your vehicle with quality fuel.See Gasoline Octane on page 277. Poor fuelquality will cause your engine not to run asefficiently as designed. You may notice this asstalling after start-up, stalling when you putthe vehicle into gear, misfiring, hesitation onacceleration, or stumbling on acceleration. (Theseconditions may go away once the engine iswarmed up.) This will be detected by the systemand cause the light to turn on.

If you experience one or more of these conditions,change the fuel brand you use. It will require atleast one full tank of the proper fuel to turn thelight off.

If none of the above steps have made the lightturn off, your dealer can check the vehicle.Your dealer has the proper test equipment anddiagnostic tools to fix any mechanical or electricalproblems that may have developed.

Emissions Inspection andMaintenance ProgramsSome state/provincial and local governments haveor may begin programs to inspect the emissioncontrol equipment on your vehicle. Failure to passthis inspection could prevent you from getting avehicle registration.

Here are some things you need to know to helpyour vehicle pass an inspection:

Your vehicle will not pass this inspection if thecheck engine light is on or not working properly.

Your vehicle will not pass this inspection ifthe OBD (on-board diagnostic) system determinesthat critical emission control systems have notbeen completely diagnosed by the system.The vehicle would be considered not ready forinspection. This can happen if you have recentlyreplaced your battery or if your battery hasrun down. The diagnostic system is designed toevaluate critical emission control systemsduring normal driving. This may take several daysof routine driving. If you have done this andyour vehicle still does not pass the inspection forlack of OBD system readiness, your dealercan prepare the vehicle for inspection.

For better radio reception, most AMradio stations boosts the power levels during theday, and then reduce these levels during the night.Static can also occur when things like stormsand power lines interfere with radio reception.When this happens, try reducing the treble onyour radio.

FM StereoFM stereo gives the best sound, but FM signalsreach only about 10 to 40 miles (16 to 65 km).Tall buildings or hills can interfere with FM signals,causing the sound to fade in and out.

XM™ Satellite Radio ServiceXM™ Satellite Radio Service gives digital radioreception from coast-to-coast in the 48 contiguousUnited States, and in Canada. Just as with FM,tall buildings or hills can interfere with satelliteradio signals, causing the sound to fade in and out.In addition, traveling or standing under heavyfoliage, bridges, garages, or tunnels can causeloss of the XM™ signal for a period of time.The radio could display NO XM SIGNAL toindicate interference.

Care of Your CDsHandle CDs carefully. Store them in their originalcases or other protective cases and away fromdirect sunlight and dust. The CD player scans thebottom surface of the disc. If the surface of aCD is damaged, such as cracked, broken,or scratched, the CD will not play properly or notat all. If the surface of a CD is soiled, take asoft, lint free cloth or dampen a clean, soft cloth ina mild, neutral detergent solution mixed withwater, and clean it. Make sure the wiping processstarts from the center to the edge.

Do not touch the bottom side of a CD whilehandling it; this could damage the surface. Pick upCDs by grasping the outer edges or the edge ofthe hole and the outer edge.

Care of the CD PlayerDo not use CD lens cleaners for CD playersbecause the lens of the CD optics can becomecontaminated by lubricants.

Fixed Mast AntennaThe fixed mast antenna can withstand most carwashes without being damaged. If the mast shouldever become slightly bent, straighten it out byhand. If the mast is badly bent, replace it.

Check occasionally to make sure the mast isstill tightened to the fender. If tightening isrequired, tighten by hand, then with a wrenchone quarter turn.

XM™ Satellite RadioAntenna SystemYour vehicle may have the XM™ Satellite Radioantenna that is located on the trunk of yourvehicle. Keep this antenna clear of snow and icebuild up for clear radio reception.

Your Driving, the Road, andYour Vehicle

Defensive DrivingThe best advice anyone can give about driving is:Drive defensively.

Please start with a very important safety device inyour vehicle: Buckle up. See Safety Belts: TheyAre for Everyone on page 18.

{CAUTION:

Defensive driving really means “Be readyfor anything.” On city streets, rural roads,or expressways, it means “Always expectthe unexpected.” Assume that pedestriansor other drivers are going to be carelessand make mistakes. Anticipate what theymight do and be ready. Rear-end collisionsare about the most preventable ofaccidents. Yet they are common. Allowenough following distance. Defensivedriving requires that a driver concentrateon the driving task. Anything that distractsfrom the driving task makes properdefensive driving more difficult and caneven cause a collision, with resultinginjury. Ask a passenger to help do thesethings, or pull off the road in a safe place todo them. These simple defensive drivingtechniques could save your life.

Drunken DrivingDeath and injury associated with drinking anddriving is a national tragedy. It is the numberone contributor to the highway death toll,claiming thousands of victims every year.

Alcohol affects four things that anyone needs todrive a vehicle:

• Judgment

• Muscular Coordination

• Vision

• Attentiveness

Police records show that almost half of all motorvehicle-related deaths involve alcohol. In mostcases, these deaths are the result of someone whowas drinking and driving. In recent years, morethan 16,000 annual motor vehicle-related deathshave been associated with the use of alcohol, withmore than 300,000 people injured.

Many adults — by some estimates, nearly halfthe adult population — choose never to drinkalcohol, so they never drive after drinking.For persons under 21, it is against the law inevery U.S. state to drink alcohol. There are goodmedical, psychological, and developmentalreasons for these laws.

The obvious way to eliminate the leading highwaysafety problem is for people never to drinkalcohol and then drive. But what if people do?How much is “too much” if someone plansto drive? It is a lot less than many might think.Although it depends on each person and situation,here is some general information on the problem.

The Blood Alcohol Concentration (BAC) ofsomeone who is drinking depends uponfour things:

• The amount of alcohol consumed

• The drinker’s body weight

• The amount of food that is consumed beforeand during drinking

• The length of time it has taken the drinker toconsume the alcohol

223

Page 224: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

According to the American Medical Association,a 180 lb (82 kg) person who drinks three 12 ounce(355 ml) bottles of beer in an hour will end up with aBAC of about 0.06 percent. The person wouldreach the same BAC by drinking three 4 ounce(120 ml) glasses of wine or three mixed drinks ifeach had 1-1/2 ounces (45 ml) of liquors likewhiskey, gin, or vodka.

It is the amount of alcohol that counts. For example,if the same person drank three double martinis(3 ounces or 90 ml of liquor each) within an hour,the person’s BAC would be close to 0.12 percent.A person who consumes food just before or duringdrinking will have a somewhat lower BAC level.

There is a gender difference, too. Womengenerally have a lower relative percentage ofbody water than men. Since alcohol is carried inbody water, this means that a woman generally willreach a higher BAC level than a man of hersame body weight will when each has the samenumber of drinks.

The law in most U.S. states, and throughoutCanada, sets the legal limit at 0.08 percent.In some other countries, the limit is even lower.For example, it is 0.05 percent in both Franceand Germany. The BAC limit for all commercialdrivers in the United States is 0.04 percent.

The BAC will be over 0.10 percent after three tosix drinks (in one hour). Of course, as we haveseen, it depends on how much alcohol is in thedrinks, and how quickly the person drinks them.

224

Page 225: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

But the ability to drive is affected well below a BACof 0.10 percent. Research shows that the drivingskills of many people are impaired at a BACapproaching 0.05 percent, and that the effects areworse at night. All drivers are impaired at BAClevels above 0.05 percent. Statistics show that thechance of being in a collision increases sharply fordrivers who have a BAC of 0.05 percent or above.A driver with a BAC level of 0.06 percent hasdoubled his or her chance of having a collision. At aBAC level of 0.10 percent, the chance of this driverhaving a collision is 12 times greater; at a level of0.15 percent, the chance is 25 times greater!

The body takes about an hour to rid itself of thealcohol in one drink. No amount of coffee ornumber of cold showers will speed that up.“I will be careful” is not the right answer. What ifthere is an emergency, a need to take suddenaction, as when a child darts into the street?A person with even a moderate BAC might notbe able to react quickly enough to avoid thecollision.

There is something else about drinking and drivingthat many people do not know. Medical researchshows that alcohol in a person’s system can makecrash injuries worse, especially injuries to thebrain, spinal cord, or heart. This means that whenanyone who has been drinking — driver orpassenger — is in a crash, that person’s chanceof being killed or permanently disabled ishigher than if the person had not been drinking.

{CAUTION:

Drinking and then driving is verydangerous. Your reflexes, perceptions,attentiveness, and judgment can beaffected by even a small amount ofalcohol. You can have a serious — oreven fatal — collision if you drive afterdrinking. Please do not drink and driveor ride with a driver who has beendrinking. Ride home in a cab; or if youare with a group, designate a driverwho will not drink.

Control of a VehicleYou have three systems that make your vehiclego where you want it to go. They are the brakes,the steering, and the accelerator. All threesystems have to do their work at the places wherethe tires meet the road.

Sometimes, as when you are driving on snow orice, it is easy to ask more of those control systemsthan the tires and road can provide. That meansyou can lose control of your vehicle. SeeEnhanced Traction System (ETS) on page 230.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 274.

BrakingSee Brake System Warning Light on page 167.

Braking action involves perception time andreaction time.

First, you have to decide to push on the brakepedal. That is perception time. Then you have tobring up your foot and do it. That is reaction time.

Average reaction time is about three-fourths of asecond. But that is only an average. It might be lesswith one driver and as long as two or three secondsor more with another. Age, physical condition,alertness, coordination, and eyesight all play a part.So do alcohol, drugs, and frustration. But even inthree-fourths of a second, a vehicle moving at60 mph (100 km/h) travels 66 feet (20 m). Thatcould be a lot of distance in an emergency, sokeeping enough space between your vehicle andothers is important.

And, of course, actual stopping distances varygreatly with the surface of the road, whether it ispavement or gravel; the condition of the road,whether it is wet, dry, or icy; tire tread; thecondition of the brakes; the weight of the vehicle;and the amount of brake force applied.

226

Page 227: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Avoid needless heavy braking. Some people drivein spurts — heavy acceleration followed by heavybraking — rather than keeping pace with traffic.This is a mistake. The brakes may not have time tocool between hard stops. The brakes will wear outmuch faster if you do a lot of heavy braking. If youkeep pace with the traffic and allow realisticfollowing distances, you will eliminate a lot ofunnecessary braking. That means better brakingand longer brake life.

If your vehicle’s engine ever stops while you aredriving, brake normally but do not pump thebrakes. If you do, the pedal may get harder topush down. If the engine stops, you will still havesome power brake assist. But you will use itwhen you brake. Once the power assist is usedup, it may take longer to stop and the brake pedalwill be harder to push.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 274.

Anti-Lock Brake System (ABS)Your vehicle may have the Anti-Lock BrakeSystem (ABS), an advanced electronic brakingsystem that will help prevent a braking skid.

If your vehicle has ABS,this warning light on theinstrument panel willcome on briefly whenyou start your vehicle.

When you start your engine, or when you begin todrive away, your ABS will check itself. You mayhear a momentary motor or clicking noisewhile this test is going on, and you may evennotice that your brake pedal moves or pulses alittle. This is normal.

227

Page 228: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Let us say the road is wet and you are drivingsafely. Suddenly, an animal jumps out in front ofyou. You slam on the brakes and continue braking.Here is what happens with ABS:

A computer senses that wheels are slowing down.If one of the wheels is about to stop rolling, thecomputer will separately work the brakes at eachwheel.

ABS can change the brake pressure faster thanany driver could. The computer is programmed tomake the most of available tire and roadconditions. This can help you steer around theobstacle while braking hard.

As you brake, your computer keeps receivingupdates on wheel speed and controls brakingpressure accordingly.

228

Page 229: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Remember: ABS does not change the time youneed to get your foot up to the brake pedalor always decrease stopping distance. If you gettoo close to the vehicle in front of you, you will nothave time to apply your brakes if that vehiclesuddenly slows or stops. Always leave enoughroom up ahead to stop, even though youhave ABS.

Using ABSDo not pump the brakes. Just hold the brakepedal down firmly and let anti-lock work for you.You may feel a slight brake pedal pulsationor notice some noise, but this is normal.

Braking in EmergenciesAt some time, nearly every driver gets into asituation that requires hard braking.

If you have ABS, you can steer and brake at thesame time. However, if you do not have ABS, yourfirst reaction — to hit the brake pedal hard and holdit down — may be the wrong thing to do. Yourwheels can stop rolling. Once they do, the vehiclecannot respond to your steering.

Momentum will carry it in whatever direction it washeaded when the wheels stopped rolling. Thatcould be off the road, into the very thing you weretrying to avoid, or into traffic.

If you do not have ABS, use a “squeeze” brakingtechnique. This will give you maximum brakingwhile maintaining steering control. You can do thisby pushing on the brake pedal with steadilyincreasing pressure.

In an emergency, you will probably want tosqueeze the brakes hard without locking thewheels. If you hear or feel the wheels sliding, easeoff the brake pedal. This will help you retainsteering control. If you do have ABS, it is different.See Anti-Lock Brake System (ABS) on page 227.

In many emergencies, steering can help youmore than even the very best braking.

Enhanced Traction System (ETS)Your vehicle may have an Enhanced TractionSystem (ETS) that limits wheel spin. This isespecially useful in slippery road conditions.The system operates only if it senses that oneor both of the front wheels are spinning orbeginning to lose traction. When this happens, thesystem reduces engine power and may alsoupshift the transaxle to limit wheel spin. You mayfeel or hear the system working, but this isnormal.

A LOW TRACTION message will appear on theDriver Information Center (DIC) when the tractioncontrol system is actively limiting wheel spin.Slippery road conditions may exist if this messageis displayed, so adjust your driving accordingly.

If your vehicle is in cruise control when theEnhanced Traction System begins to limit wheelspin, the cruise control will automaticallydisengage. When road conditions allow you tosafely use it again, you may re-engage the cruisecontrol. See Cruise Control on page 145.

When the system is on,this warning light willcome on to let you knowthere’s a problem.

If the warning light stays on, or comes on whenyou’re driving, there may be a problem withyour Enhanced Traction System and your vehiclemay need service. When this warning light ison, the system will not limit wheel spin. Adjust yourdriving accordingly.

The Enhanced Traction System warning light maycome on for the following reasons:

• If you turn the system off by moving the shiftlever to LOW (L), the warning light will comeon and stay on. To turn the system backon, move the shift lever back to a positionother than LOW (L). The warning light shouldgo off.

230

Page 231: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

• The warning light will come on when you setyour parking brake with the engine running,and it will stay on if your parking brakedoes not release fully. If the transaxle shiftlever is in any position other than LOW (L) andthe warning light stays on after your parkingbrake is fully released, it means there isa problem with the system.

• If the traction control system is affected by anengine related problem, the system will turnoff and the warning light will come on.

If the Enhanced Traction System warning lightcomes on and stays on for an extended period oftime when the transaxle shift lever is in any positionother than LOW (L), your vehicle needs service.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 274 for more information.

Limited-Slip DifferentialYour vehicle may have this feature. A limited-sliptransaxle can give you additional traction on snow,mud, ice, sand or gravel. It works like a standardtransaxle most of the time, but when one of the frontwheels loses traction, this feature will allow thewheel with traction to move the vehicle.

Steering

Electric Power SteeringIf the engine stalls while you are driving, thepower steering assist system will continueto operate until you are able to stop your vehicle.If you lose power steering assist because theelectric power steering system is not functioning,you can steer, but it will take more effort.

If you turn the steering wheel in either directionseveral times until it stops, or hold the steeringwheel in the stopped position for an extendedamount of time, you may notice a reduced amountof power steering assist. The normal amount ofpower steering assist should return shortly after afew normal steering movements.

231

Page 232: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

The electric power steering system does notrequire regular maintenance. If you suspectsteering system problems and/or the POWERSTEERING message comes on, contactyour dealer for service repairs. See DIC Warningsand Messages on page 180.

Steering TipsIt is important to take curves at a reasonable speed.

A lot of the “driver lost control” accidents mentionedon the news happen on curves. Here is why:

Experienced driver or beginner, each of us issubject to the same laws of physics when driving oncurves. The traction of the tires against the roadsurface makes it possible for the vehicle to changeits path when you turn the front wheels. If there isno traction, inertia will keep the vehicle going in thesame direction. If you have ever tried to steer avehicle on wet ice, you will understand this.

The traction you can get in a curve depends onthe condition of your tires and the road surface,the angle at which the curve is banked, andyour speed. While you are in a curve, speed is theone factor you can control.

Suppose you are steering through a sharp curve.Then you suddenly apply the brakes. Both controlsystems — steering and braking — have to do theirwork where the tires meet the road. Unless youhave four-wheel anti-lock brakes, adding the hardbraking can demand too much of those places.You can lose control.

The same thing can happen if you are steeringthrough a sharp curve and you suddenlyaccelerate. Those two control systems — steeringand acceleration — can overwhelm those placeswhere the tires meet the road and make you losecontrol. See Enhanced Traction System (ETS) onpage 230.

What should you do if this ever happens? Ease upon the brake or accelerator pedal, steer the vehiclethe way you want it to go, and slow down.

Speed limit signs near curves warn that youshould adjust your speed. Of course, the postedspeeds are based on good weather and roadconditions. Under less favorable conditions you willwant to go slower.

If you need to reduce your speed as you approacha curve, do it before you enter the curve, whileyour front wheels are straight ahead.

232

Page 233: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Try to adjust your speed so you can “drive”through the curve. Maintain a reasonable, steadyspeed. Wait to accelerate until you are out ofthe curve, and then accelerate gently intothe straightaway.Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 274.

Steering in EmergenciesThere are times when steering can be moreeffective than braking. For example, you come overa hill and find a truck stopped in your lane, or a carsuddenly pulls out from nowhere, or a child dartsout from between parked cars and stops right infront of you. You can avoid these problems bybraking — if you can stop in time. But sometimesyou cannot; there is not room. That is the time forevasive action — steering around the problem.Your vehicle can perform very well in emergencieslike these. First apply your brakes — but, unlessyou have anti-lock brakes, not enough to lockyour wheels.See Braking on page 226. It is better to remove asmuch speed as you can from a possible collision.Then steer around the problem, to the left orright depending on the space available.

An emergency like this requires close attentionand a quick decision. If you are holding thesteering wheel at the recommended 9 and3 o’clock positions, you can turn it a full180 degrees very quickly without removing eitherhand. But you have to act fast, steer quickly,and just as quickly straighten the wheel once youhave avoided the object.

The fact that such emergency situations are alwayspossible is a good reason to practice defensivedriving at all times and wear safety belts properly.

233

Off-Road RecoveryYou may find that your right wheels have droppedoff the edge of a road onto the shoulder whileyou are driving.

If the level of the shoulder is only slightly below thepavement, recovery should be fairly easy. Ease offthe accelerator and then, if there is nothing in theway, steer so that your vehicle straddles the edgeof the pavement. You can turn the steering wheelup to one-quarter turn until the right front tirecontacts the pavement edge. Then turn yoursteering wheel to go straight down the roadway.

PassingThe driver of a vehicle about to pass another on atwo-lane highway waits for just the right moment,accelerates, moves around the vehicle ahead, thengoes back into the right lane again. A simplemaneuver?

Not necessarily! Passing another vehicle on atwo-lane highway is a potentially dangerous move,since the passing vehicle occupies the samelane as oncoming traffic for several seconds.A miscalculation, an error in judgment, or a briefsurrender to frustration or anger can suddenlyput the passing driver face to face with the worstof all traffic accidents — the head-on collision.

So here are some tips for passing:

• Drive ahead. Look down the road, to thesides, and to crossroads for situationsthat might affect your passing patterns. If youhave any doubt whatsoever about makinga successful pass, wait for a better time.

234

Page 235: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

• Watch for traffic signs, pavement markings,and lines. If you can see a sign up aheadthat might indicate a turn or an intersection,delay your pass. A broken center lineusually indicates it is all right to pass, providingthe road ahead is clear. Never cross a solidline on your side of the lane or a double solidline, even if the road seems empty ofapproaching traffic.

• Do not get too close to the vehicle you wantto pass while you are awaiting an opportunity.For one thing, following too closely reducesyour area of vision, especially if you arefollowing a larger vehicle. Also, you will nothave adequate space if the vehicle aheadsuddenly slows or stops. Keep back areasonable distance.

• When it looks like a chance to pass is comingup, start to accelerate but stay in the rightlane and do not get too close. Time your moveso you will be increasing speed as the timecomes to move into the other lane. If the wayis clear to pass, you will have a runningstart that more than makes up for the distanceyou would lose by dropping back.

And if something happens to cause you tocancel your pass, you need only slowdown and drop back again and wait foranother opportunity.

• If other vehicles are lined up to pass a slowvehicle, wait your turn. But take care thatsomeone is not trying to pass you as you pullout to pass the slow vehicle. Remember toglance over your shoulder and check theblind spot.

• Check your vehicle’s mirrors, glance over yourshoulder, and start your left lane changesignal before moving out of the right lane topass. When you are far enough ahead ofthe passed vehicle to see its front inyour vehicle’s inside mirror, activate the rightlane change signal and move back intothe right lane. Remember that your vehicle’spassenger side outside mirror is convex.The vehicle you just passed may seem to befarther away from you than it really is.

235

Page 236: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

• Try not to pass more than one vehicle at atime on two-lane roads. Reconsider beforepassing the next vehicle.

• Do not overtake a slowly moving vehicle toorapidly. Even though the brake lamps arenot flashing, it may be slowing down or startingto turn.

• If you are being passed, make it easy for thefollowing driver to get ahead of you. Perhapsyou can ease a little to the right.

Loss of ControlLet us review what driving experts say about whathappens when the three control systems — brakes,steering, and acceleration — do not have enoughfriction where the tires meet the road to do what thedriver has asked.

In any emergency, do not give up. Keep trying tosteer and constantly seek an escape route orarea of less danger.

SkiddingIn a skid, a driver can lose control of the vehicle.Defensive drivers avoid most skids by takingreasonable care suited to existing conditions, andby not overdriving those conditions. But skidsare always possible.

The three types of skids correspond to yourvehicle’s three control systems. In the braking skid,your wheels are not rolling. In the steering orcornering skid, too much speed or steering in acurve causes tires to slip and lose cornering force.And in the acceleration skid, too much throttlecauses the driving wheels to spin.

A cornering skid is best handled by easing yourfoot off the accelerator pedal.

If you have the Enhanced Traction System (ETS),remember: It helps to avoid only the accelerationskid. See Enhanced Traction System (ETS)on page 230. If you do not have the EnhancedTraction System, or if the system is off, thenan acceleration skid is also best handled by easingyour foot off the accelerator pedal.

236

Page 237: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

If your vehicle starts to slide, ease your foot offthe accelerator pedal and quickly steer theway you want the vehicle to go. If you startsteering quickly enough, your vehicle maystraighten out. Always be ready for a second skidif it occurs.

Of course, traction is reduced when water, snow,ice, gravel, or other material is on the road.For safety, you will want to slow down and adjustyour driving to these conditions. It is importantto slow down on slippery surfaces becausestopping distance will be longer and vehicle controlmore limited.

While driving on a surface with reduced traction,try your best to avoid sudden steering, acceleration,or braking, including reducing vehicle speed byshifting to a lower gear. Any sudden changes couldcause the tires to slide. You may not realize thesurface is slippery until your vehicle is skidding.Learn to recognize warning clues — such asenough water, ice, or packed snow on the road tomake a mirrored surface — and slow down whenyou have any doubt.

If you have the Anti-Lock Brake System (ABS),remember: It helps avoid only the brakingskid. If you do not have ABS, then in a brakingskid, where the wheels are no longer rolling,release enough pressure on the brakes to get thewheels rolling again. This restores steeringcontrol. Push the brake pedal down steadily whenyou have to stop suddenly. As long as thewheels are rolling, you will have steering control.

Driving at NightNight driving is more dangerous than day driving.One reason is that some drivers are likely tobe impaired — by alcohol or drugs, with nightvision problems, or by fatigue.

Here are some tips on night driving.

• Drive defensively.

• Do not drink and drive.

• Adjust the inside rearview mirror to reduce theglare from headlamps behind you.

• Since you cannot see as well, you may needto slow down and keep more space betweenyou and other vehicles.

• Slow down, especially on higher speed roads.Your vehicle’s headlamps can light up only somuch road ahead.

• In remote areas, watch for animals.

• If you are tired, pull off the road in a safeplace and rest.

No one can see as well at night as in the daytime.But as we get older these differences increase.A 50-year-old driver may require at least twice asmuch light to see the same thing at night as a20-year-old.

What you do in the daytime can also affect yournight vision. For example, if you spend theday in bright sunshine you are wise to wearsunglasses. Your eyes will have less troubleadjusting to night. But if you are driving, do notwear sunglasses at night. They may cut down onglare from headlamps, but they also make alot of things invisible.

You can be temporarily blinded by approachingheadlamps. It can take a second or two, oreven several seconds, for your eyes to re-adjustto the dark. When you are faced with severe glare,as from a driver who does not lower the highbeams, or a vehicle with misaimed headlamps,slow down a little. Avoid staring directly intothe approaching headlamps.

Keep the windshield and all the glass on yourvehicle clean — inside and out. Glare at night ismade much worse by dirt on the glass. Eventhe inside of the glass can build up a film causedby dust. Dirty glass makes lights dazzle andflash more than clean glass would, making thepupils of your eyes contract repeatedly.

Remember that the headlamps light up far less of aroadway when you are in a turn or curve. Keep youreyes moving; that way, it is easier to pick out dimlylighted objects. Just as the headlamps should bechecked regularly for proper aim, so should youreyes be examined regularly. Some drivers sufferfrom night blindness — the inability to see in dimlight — and are not even aware of it.

Driving in Rain and on Wet Roads

Rain and wet roads can mean driving trouble. On awet road, you cannot stop, accelerate, or turn aswell because your tire-to-road traction is not asgood as on dry roads. And, if your tires do not havemuch tread left, you will get even less traction.

239

Page 240: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

It is always wise to go slower and be cautious if rainstarts to fall while you are driving. The surface mayget wet suddenly when your reflexes are tuned fordriving on dry pavement.

The heavier the rain, the harder it is to see. Even ifyour windshield wiper blades are in good shape, aheavy rain can make it harder to see road signs andtraffic signals, pavement markings, the edge of theroad, and even people walking.

It is wise to keep your windshield wiping equipmentin good shape and keep your windshield washerfluid reservoir filled with washer fluid. Replace yourwindshield wiper inserts when they show signsof streaking or missing areas on the windshield, orwhen strips of rubber start to separate from theinserts.

{CAUTION:

Wet brakes can cause accidents. They maynot work as well in a quick stop and maycause pulling to one side. You could losecontrol of the vehicle.

After driving through a large puddle ofwater or a car wash, apply your brake pedallightly until your brakes work normally.

Driving too fast through large water puddles oreven going through some car washes can causeproblems, too. The water may affect your brakes.Try to avoid puddles. But if you cannot, try to slowdown before you hit them.

HydroplaningHydroplaning is dangerous. So much water canbuild up under your tires that they can actually rideon the water. This can happen if the road is wetenough and you are going fast enough. When yourvehicle is hydroplaning, it has little or no contactwith the road.

Hydroplaning does not happen often. But it canif your tires do not have much tread or if thepressure in one or more is low. It can happen if alot of water is standing on the road. If you cansee reflections from trees, telephone poles,or other vehicles, and raindrops dimple the water’ssurface, there could be hydroplaning.

Hydroplaning usually happens at higher speeds.There just is not a hard and fast rule abouthydroplaning. The best advice is to slow downwhen it is raining.

Driving Through Deep Standing WaterNotice: If you drive too quickly throughdeep puddles or standing water, water cancome in through your engine’s air intake andbadly damage your engine. Never drive throughwater that is slightly lower than the underbodyof your vehicle. If you cannot avoid deeppuddles or standing water, drive through themvery slowly.

Driving Through Flowing Water

{CAUTION:

Flowing or rushing water creates strongforces. If you try to drive through flowingwater, as you might at a low watercrossing, your vehicle can be carried away.As little as six inches of flowing water cancarry away a smaller vehicle. If thishappens, you and other vehicle occupantscould drown. Do not ignore police warningsigns, and otherwise be very cautiousabout trying to drive through flowing water.

Some Other Rainy Weather Tips• Besides slowing down, allow some extra

following distance. And be especially carefulwhen you pass another vehicle. Allow yourselfmore clear room ahead, and be prepared tohave your view restricted by road spray.

• Have good tires with proper tread depth.See Tires on page 334.

City Driving

One of the biggest problems with city streets isthe amount of traffic on them. You will wantto watch out for what the other drivers are doingand pay attention to traffic signals.

242

Page 243: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Here are ways to increase your safety in citydriving:

• Know the best way to get to where you aregoing. Get a city map and plan your tripinto an unknown part of the city just as youwould for a cross-country trip.

• Try to use the freeways that rim and crisscrossmost large cities. You will save time andenergy. See Freeway Driving on page 243.

• Treat a green light as a warning signal.A traffic light is there because the corneris busy enough to need it. When a light turnsgreen, and just before you start to move,check both ways for vehicles that have notcleared the intersection or may be running thered light.

Freeway Driving

Mile for mile, freeways — also called thruways,parkways, expressways, turnpikes, orsuperhighways — are the safest of all roads.But they have their own special rules.

243

Page 244: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

The most important advice on freeway driving is:Keep up with traffic and keep to the right. Drive atthe same speed most of the other drivers aredriving. Too-fast or too-slow driving breaks asmooth traffic flow. Treat the left lane on a freewayas a passing lane.

At the entrance, there is usually a ramp that leadsto the freeway. If you have a clear view of thefreeway as you drive along the entrance ramp, youshould begin to check traffic. Try to determinewhere you expect to blend with the flow. Try tomerge into the gap at close to the prevailing speed.Switch on your turn signal, check your mirrors, andglance over your shoulder as often as necessary.Try to blend smoothly with the traffic flow.

Once you are on the freeway, adjust your speedto the posted limit or to the prevailing rate if itis slower. Stay in the right lane unless you wantto pass.

Before changing lanes, check your mirrors.Then use your turn signal.

Just before you leave the lane, glance quicklyover your shoulder to make sure there is notanother vehicle in your blind spot.

Once you are moving on the freeway, makecertain you allow a reasonable following distance.

Expect to move slightly slower at night.

When you want to leave the freeway, move to theproper lane well in advance. If you miss yourexit, do not, under any circumstances, stop andback up. Drive on to the next exit.

The exit ramp can be curved, sometimes quitesharply. The exit speed is usually posted. Reduceyour speed according to your speedometer, notto your sense of motion. After driving for anydistance at higher speeds, you may tend to thinkyou are going slower than you actually are.

Before Leaving on a Long TripMake sure you are ready. Try to be well rested.If you must start when you are not fresh — such asafter a day’s work — do not plan to make too manymiles that first part of the journey. Wear comfortableclothing and shoes you can easily drive in.

Is your vehicle ready for a long trip? If you keep itserviced and maintained, it is ready to go. If itneeds service, have it done before starting out.

Of course, you will find experienced and ableservice experts in GM dealerships all across NorthAmerica. They will be ready and willing to help ifyou need it.

Here are some things you can check before a trip:

• Windshield Washer Fluid: Is the reservoirfull? Are all windows clean inside and outside?

• Wiper Blades: Are they in good shape?

• Fuel, Engine Oil, Other Fluids: Have youchecked all levels?

• Lamps: Are they all working? Are the lensesclean?

• Tires: They are vitally important to a safe,trouble-free trip. Is the tread good enoughfor long-distance driving? Are the tiresall inflated to the recommended pressure?

• Weather Forecasts: What is the weatheroutlook along your route? Should youdelay your trip a short time to avoid a majorstorm system?

• Maps: Do you have up-to-date maps?

Highway HypnosisIs there actually such a condition as highwayhypnosis? Or is it just plain falling asleep at thewheel? Call it highway hypnosis, lack ofawareness, or whatever.

There is something about an easy stretch of roadwith the same scenery, along with the hum of thetires on the road, the drone of the engine, and therush of the wind against the vehicle that can makeyou sleepy. Do not let it happen to you! If it does,your vehicle can leave the road in less than asecond, and you could crash and be injured.

What can you do about highway hypnosis?First, be aware that it can happen.

Then here are some tips:

• Make sure your vehicle is well ventilated,with a comfortably cool interior.

• Keep your eyes moving. Scan the road aheadand to the sides. Check your rearview mirrorsand your instruments frequently.

• If you get sleepy, pull off the road into a rest,service, or parking area and take a nap, getsome exercise, or both. For safety, treatdrowsiness on the highway as an emergency.

Hill and Mountain Roads

Driving on steep hills or mountains is differentfrom driving in flat or rolling terrain.

If you drive regularly in steep country, or if you areplanning to visit there, here are some tips thatcan make your trips safer and more enjoyable.

• Keep your vehicle in good shape. Checkall fluid levels and also the brakes, tires,cooling system, and transaxle. These partscan work hard on mountain roads.

{CAUTION:

If you do not shift down, your brakescould get so hot that they would not workwell. You would then have poor braking oreven none going down a hill. You couldcrash. Shift down to let your engine assistyour brakes on a steep downhill slope.

246

Page 247: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

{CAUTION:

Coasting downhill in NEUTRAL (N) or withthe ignition off is dangerous. Your brakeswill have to do all the work of slowingdown. They could get so hot that theywould not work well. You would then havepoor braking or even none going down ahill. You could crash. Always have yourengine running and your vehicle in gearwhen you go downhill.

• Know how to go down hills. The most importantthing to know is this: let your engine do some ofthe slowing down. Shift to a lower gear whenyou go down a steep or long hill.

• Know how to go uphill. You may want to shiftdown to a lower gear. The lower gears helpcool your engine and transaxle, and you canclimb the hill better.

• Stay in your own lane when driving on two-laneroads in hills or mountains. Do not swing wideor cut across the center of the road. Drive atspeeds that let you stay in your own lane.

• As you go over the top of a hill, be alert. Therecould be something in your lane, like a stalledcar or an accident.

• You may see highway signs on mountains thatwarn of special problems. Examples are longgrades, passing or no-passing zones, a fallingrocks area, or winding roads. Be alert to theseand take appropriate action.

Winter Driving

Here are some tips for winter driving:

• Have your vehicle in good shape for winter.

• You may want to put winter emergencysupplies in your vehicle.

Also see Tires on page 334.

Include an ice scraper, a small brush or broom, asupply of windshield washer fluid, a rag, somewinter outer clothing, a small shovel, a flashlight, ared cloth, and a couple of reflective warningtriangles. And, if you will be driving under severeconditions, include a small bag of sand, apiece of old carpet, or a couple of burlap bags tohelp provide traction. Be sure you properlysecure these items in your vehicle.

Driving on Snow or IceMost of the time, those places where the tiresmeet the road probably have good traction.

However, if there is snow or ice between the tiresand the road, you can have a very slipperysituation. You will have a lot less traction, or grip,and will need to be very careful.

248

Page 249: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

What is the worst time for this? Wet ice. Very coldsnow or ice can be slick and hard to drive on.But wet ice can be even more trouble because itmay offer the least traction of all. You can getwet ice when it is about freezing, 32°F (0°C), andfreezing rain begins to fall. Try to avoid drivingon wet ice until salt and sand crews can get there.

Whatever the condition — smooth ice, packed,blowing, or loose snow — drive with caution.

If you have the Enhanced Traction System (ETS),keep the transaxle shift lever in DRIVE (D) sothe system will be able to improve your ability toaccelerate when driving on a slippery road.Even though your vehicle has this system, you willwant to slow down and adjust your driving tothe road conditions. Under certain conditions, youmay want to turn the traction system off, suchas when driving through deep snow and loosegravel, to help maintain vehicle motion atlower speeds. See Enhanced Traction System(ETS) on page 230.

If your vehicle does not have ETS, accelerategently. Try not to break the fragile traction. If youaccelerate too fast, the drive wheels will spinand polish the surface under the tires even more.

Unless your vehicle has the Anti-Lock BrakeSystem (ABS), you will want to brake very gently,too. If your vehicle does have ABS, seeAnti-Lock Brake System (ABS) on page 227.This system improves your vehicle’s stabilitywhen you make a hard stop on a slippery road.

249

Page 250: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Whether your vehicle has ABS or not, you willwant to begin stopping sooner than you would ondry pavement. Without ABS, if you feel yourvehicle begin to slide, let up on the brakes a little.Push the brake pedal down steadily to get themost traction you can.

Remember, unless your vehicle has ABS, if youbrake so hard that the wheels stop rolling, you willjust slide. Brake so the wheels always keeprolling and you can still steer.

• Whatever your vehicle’s braking system, allowgreater following distance on any slippery road.

• Watch for slippery spots. The road might befine until you hit a spot that is covered with ice.On an otherwise clear road, ice patches mayappear in shaded areas where the sun cannotreach, such as around clumps of trees, behindbuildings, or under bridges. Sometimes thesurface of a curve or an overpass may remainicy when the surrounding roads are clear. If yousee a patch of ice ahead of you, brake beforeyou are on it. Try not to brake while you areactually on the ice, and avoid sudden steeringmaneuvers.

If You Are Caught in a BlizzardIf you are stopped by heavy snow, you could be ina serious situation. You should probably staywith your vehicle unless you know for sure that youare near help and you can hike through thesnow. Here are some things to do to summonhelp and keep yourself and your passengers safe:

• Turn on your hazard flashers.

• Tie a red cloth to your vehicle to alert policethat you have been stopped by the snow.

• Put on extra clothing or wrap a blanket aroundyou. If you do not have blankets or extraclothing, make body insulators fromnewspapers, burlap bags, rags, floormats — anything you can wrap around yourselfor tuck under your clothing to keep warm.

250

Page 251: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

You can run the engine to keep warm, but becareful.

{CAUTION:

Snow can trap exhaust gases under yourvehicle. This can cause deadly CO(carbon monoxide) gas to get inside.CO could overcome you and kill you.You cannot see it or smell it, so you mightnot know it is in your vehicle. Clear awaysnow from around the base of yourvehicle, especially any that is blockingyour exhaust pipe. And check aroundagain from time to time to be sure snowdoes not collect there.

Open a window just a little on the side ofthe vehicle that is away from the wind.This will help keep CO out.

Run the engine only as long as you must.This saves fuel. When you run the engine, make itgo a little faster than just idle. That is, push theaccelerator slightly. This uses less fuel for the heatthat you get and it keeps the battery charged.

251

Page 252: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

You will need a well-charged battery to restart thevehicle, and possibly for signaling later on withthe headlamps. Let the heater run for a while.

Then, shut the engine off and close the windowalmost all the way to preserve the heat. Startthe engine again and repeat this only when youfeel really uncomfortable from the cold. But do it aslittle as possible. Preserve the fuel as long asyou can. To help keep warm, you can get out ofthe vehicle and do some fairly vigorous exercisesevery half hour or so until help comes.

If Your Vehicle is Stuck in Sand,Mud, Ice, or SnowIn order to free your vehicle when it is stuck,you will need to spin the wheels, but you do notwant to spin your wheels too fast. The methodknown as rocking can help you get out when youare stuck, but you must use caution.

{CAUTION:

If you let your vehicle’s tires spin at highspeed, they can explode, and you or otherscould be injured. And, the transaxle orother parts of the vehicle can overheat.That could cause an engine compartmentfire or other damage. When you are stuck,spin the wheels as little as possible. Do notspin the wheels above 35 mph (55 km/h) asshown on the speedometer.

Notice: Spinning the wheels can destroy partsof your vehicle as well as the tires. If youspin the wheels too fast while shiftingthe transaxle back and forth, you can destroythe transaxle. See Rocking Your Vehicle toGet It Out on page 253.

For information about using tire chains on yourvehicle, see Tire Chains on page 353.

252

Page 253: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Rocking Your Vehicle to Get It OutFirst, turn the steering wheel left and right.That will clear the area around the front wheels.Then shift back and forth between REVERSE (R)and a forward gear, or with a manual transaxle,between FIRST (1) or SECOND (2) andREVERSE (R), spinning the wheels as little aspossible. Release the accelerator pedal while youshift, and press lightly on the accelerator pedalwhen the transaxle is in gear. By slowly spinningthe wheels in the forward and reverse directions,you will cause a rocking motion that may free yourvehicle. If that does not get your vehicle outafter a few tries, it may need to be towed out.If your vehicle does need to be towed out,see Towing Your Vehicle on page 258.

Loading Your VehicleIt is very important to know how much weightyour vehicle can carry. This weight is called thevehicle capacity weight and includes the weight ofall occupants, cargo and all nonfactory-installedoptions. Two labels on your vehicle show howmuch weight it may properly carry, the Tireand Loading Information label and theCertification label.

{CAUTION:

Do not load your vehicle any heavier thanthe Gross Vehicle Weight Rating (GVWR),or either the maximum front or rear GrossAxle Weight Rating (GAWR). If you do,parts on your vehicle can break, and itcan change the way your vehicle handles.These could cause you to lose controland crash. Also, overloading can shortenthe life of your vehicle.

253

Tire and Loading Information Label

A vehicle specific Tire and Loading Informationlabel is attached to the vehicle’s center pillar(B-pillar). With the driver’s door open, you will findthe label either attached above the door lock postfor a two door vehicle or below the door lock postfor a four door vehicle. The Tire and LoadingInformation label shows the number of occupantseating positions (A), and the maximum vehiclecapacity weight (B) in kilograms and pounds.

The Tire and Loading Information label also showsthe tire size of the original equipment tires (C) andthe recommended cold tire inflation pressures (D).For more information on tires and inflation see Tireson page 334 and Inflation - Tire Pressure onpage 342.

There is also important loading information on theCertification label. It tells you the Gross VehicleWeight Rating (GVWR) and the Gross Axle WeightRating (GAWR) for the front and rear axle; see“Certification Label” later in this section.

Steps for Determining Correct Load Limit1. Locate the statement “The combined weight of

occupants and cargo should never exceedXXX kg or XXX lbs” on your vehicle placard.

2. Determine the combined weight of the driverand passengers that will be riding in yourvehicle.

3. Subtract the combined weight of the driverand passengers from XXX kg or XXX lbs.

Label Example

254

Page 255: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

4. The resulting figure equals the availableamount of cargo and luggage load capacity.For example, if the “XXX” amount equals1400 lbs and there will be five 150 lbpassengers in your vehicle, the amount ofavailable cargo and luggage load capacity is650 lbs (1400 − 750 (5 x 150) = 650 lbs).

5. Determine the combined weight of luggageand cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculated inStep 4.

6. If your vehicle will be towing a trailer, the loadfrom your trailer will be transferred to yourvehicle. Consult this manual to determine howthis reduces the available cargo and luggageload capacity of your vehicle.If your vehicle can tow a trailer, see Towing aTrailer (Manual Transaxle) on page 261 orTowing a Trailer (Automatic Transaxle)on page 261 for important information ontowing a trailer, towing safety rules, andtrailering tips.

Certification Label

A vehicle specific Certification label, found onthe rear edge of the driver’s door, tells youthe gross weight capacity of your vehicle, calledthe Gross Vehicle Weight Rating (GVWR).The GVWR includes the weight of the vehicle, alloccupants, fuel, and cargo. Never exceed theGVWR for your vehicle, or the Gross Axle WeightRating (GAWR) for either the front or rear axle.

And, if you do have a heavy load, you shouldspread it out. See “Steps for Determining CorrectLoad Limit” earlier in this section.

{CAUTION:

Do not load your vehicle any heavier thanthe Gross Vehicle Weight Rating (GVWR),or either the maximum front or rear GrossAxle Weight Rating (GAWR). If you do,parts on your vehicle can break, and it canchange the way your vehicle handles.These could cause you to lose control andcrash. Also, overloading can shorten thelife of your vehicle.

If you put things inside your vehicle — likesuitcases, tools, packages, or anythingelse — they will go as fast as the vehicle goes.If you have to stop or turn quickly, or if there is acrash, they will keep going.

{CAUTION:

Things you put inside your vehicle canstrike and injure people in a sudden stopor turn, or in a crash.

• Put things in the trunk of your vehicle.In a trunk, put them as far forward as youcan. Try to spread the weight evenly.

• Never stack heavier things, likesuitcases, inside the vehicle so thatsome of them are above the tops ofthe seats.

• Do not leave an unsecured childrestraint in your vehicle.

• When you carry something inside thevehicle, secure it whenever you can.

• Do not leave a seat folded downunless you need to.

Towing

Towing Your VehicleConsult your dealer or a professional towingservice if you need to have your disabled vehicletowed. See Roadside Assistance Program onpage 416.

If you want to tow your vehicle behind anothervehicle for recreational purposes (such asbehind a motorhome), see “Recreational VehicleTowing” following.

Recreational Vehicle TowingRecreational vehicle towing means towing yourvehicle behind another vehicle — such as behind amotorhome. The two most common types ofrecreational vehicle towing are known as “dinghytowing” (towing your vehicle with all four wheelson the ground) and “dolly towing” (towingyour vehicle with two wheels on the ground andtwo wheels up on a device known as a “dolly”).

With the proper preparation and equipment,many vehicles can be towed in these ways.See “Dinghy Towing” and “Dolly Towing,”following.

Here are some important things to consider beforeyou do recreational vehicle towing:

• What is the towing capacity of the towingvehicle? Be sure you read the tow vehiclemanufacturer’s recommendations.

• How far will you tow? Some vehicles haverestrictions on how far and how long theycan tow.

• Do you have the proper towing equipment?See your dealer or trailering professionalfor additional advice and equipmentrecommendations.

• Is your vehicle ready to be towed? Just asyou would prepare your vehicle for a longtrip, you will want to make sure your vehicle isprepared to be towed. See Before Leavingon a Long Trip on page 244.

259

Dinghy TowingYou may dinghy tow your vehicle from the frontfollowing these steps:

1. Set the parking brake.

2. Turn the ignition key to ACC to unlock thesteering wheel.

3. Shift an automatic transaxle to NEUTRAL (N)or a manual transaxle to NEUTRAL.

4. Release the parking brake.

To prevent the battery from draining while thevehicle is being towed, remove the following fusefrom the floor console fuse block: 8 (IgnitionSwitch, PASS-Key® III+). See Floor Console FuseBlock on page 380 for more information.

Remember to reinstall the fuse once you havereached your destination.

Notice: If you exceed 65 mph (105 km/h) whiletowing your vehicle, it could be damaged.Never exceed 65 mph (105 km/h) while towingyour vehicle.

Notice: Towing your vehicle from the rearcould damage it. Also, repairs would notbe covered by the warranty. Never have yourvehicle towed from the rear.

Dolly TowingYour vehicle cannot be dolly towed, but can bedinghy towed. See “Dinghy Towing” earlier in thissection.

Notice: Dolly towing your vehicle maycause damage because of reduced groundclearance. Always tow your vehicle usingthe dinghy towing procedure listed in thissection or put your vehicle on a flatbed truck.

Towing a Trailer (Manual Transaxle)Do not tow a trailer if your vehicle is equippedwith a manual transaxle. If you have theCobalt SS, you can tow a trailer. See “Towing aTrailer” in the Index for more information.

Towing a Trailer(Automatic Transaxle)

{CAUTION:

If you do not use the correct equipmentand drive properly, you can lose controlwhen you pull a trailer. For example, if thetrailer is too heavy, the brakes may notwork well — or even at all. You and yourpassengers could be seriously injured.You may also damage your vehicle; theresulting repairs would not be covered byyour warranty. Pull a trailer only if you havefollowed all the steps in this section. Askyour dealer for advice and informationabout towing a trailer with your vehicle.

Your vehicle can tow a trailer if it is equipped withthe proper trailer towing equipment. If your vehicleis not equipped as stated above, do not tow atrailer.

To identify the trailering capacity of your vehicle,you should read the information in “Weight of theTrailer” that appears later in this section. Traileringis different than just driving your vehicle by itself.Trailering means changes in handling, acceleration,braking, durability and fuel economy. Successful,safe trailering takes correct equipment, and it has tobe used properly.

That is the reason for this part. In it are manytime-tested, important trailering tips and safetyrules. Many of these are important for your safetyand that of your passengers. So please readthis section carefully before you pull a trailer.

Load-pulling components such as the engine,transaxle, wheel assemblies and tires are forcedto work harder against the drag of the addedweight. The engine is required to operateat relatively higher speeds and under greaterloads, generating extra heat. Also, the trailer addsconsiderably to wind resistance, increasing thepulling requirements.

If You Do Decide To Pull A TrailerIf you do, here are some important points:

• There are many different laws, including speedlimit restrictions, having to do with trailering.Make sure your rig will be legal, not only whereyou live but also where you will be driving.A good source for this information can be stateor provincial police.

• Consider using a sway control. You can ask ahitch dealer about sway controls.

• Do not tow a trailer at all during the first1,000 miles (1 600 km) your new vehicleis driven. Your engine, axle or other partscould be damaged.

• Then, during the first 500 miles (800 km) thatyou tow a trailer, do not drive over 50 mph(80 km/h) and do not make starts at fullthrottle. This helps your engine and other partsof your vehicle wear in at the heavier loads.

• Obey speed limit restrictions when towing atrailer. Do not drive faster than the maximumposted speed for trailers, or no more than55 mph (90 km/h), to save wear on yourvehicle’s parts.

262

• Do not tow when the outside air temperatureis above 100°F (38°C).

• Do not tow more than 1,000 miles (1 600 km)per year.

Three important considerations have to do withweight:

• The weight of the trailer

• The weight of the trailer tongue

• The total weight on your vehicle’s tires

Weight of the TrailerHow heavy can a trailer safely be?

It should never weigh more than 1,000 lbs(450 kg). But even that can be too heavy.

It depends on how you plan to use your rig.For example, speed, altitude, road grades, outsidetemperature and how much your vehicle is usedto pull a trailer are all important. It can also dependon any special equipment that you have on yourvehicle, and the amount of tongue weight thevehicle can carry. See “Weight of the TrailerTongue” later in this section for more information.

Maximum trailer weight is calculated assumingonly the driver is in the tow vehicle and it has allthe required trailering equipment. The weightof additional optional equipment, passengers andcargo must be subtracted from the maximumtrailer weight.

Weight of the Trailer TongueThe tongue load (A) of any trailer is an importantweight to measure because it affects the totalor gross weight of your vehicle. The Gross VehicleWeight (GVW) includes the curb weight of thevehicle, any cargo you may carry in it, andthe people who will be riding in the vehicle. If youhave a lot of options, equipment, passengers,or cargo in your vehicle, it will reduce the tongueweight your vehicle can carry, which will alsoreduce the trailer weight your vehicle can tow.And if you tow a trailer, you must add the tongueload to the GVW because your vehicle will becarrying that weight, too. See Loading YourVehicle on page 253 for more information aboutyour vehicle’s maximum load capacity.

If you are using a weight-carrying hitch, the trailertongue (A) should weigh 10 to 15 percent ofthe total loaded trailer weight (B).

After you have loaded your trailer, weigh the trailerand then the tongue, separately, to see if theweights are proper. If they are not, you may beable to get them right simply by moving someitems around in the trailer.

264

Page 265: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Total Weight on Your Vehicle’s TiresBe sure your vehicle’s tires are inflated to theupper limit for cold tires. You will find thesenumbers on the Tire-Loading Information label.See Loading Your Vehicle on page 253. Then besure you do not go over the GVW limit for yourvehicle, including the weight of the trailer tongue.

HitchesIt is important to have the correct hitch equipment.Crosswinds, large trucks going by and roughroads are a few reasons why you will need theright hitch. Here are some rules to follow:

• The rear bumper on your vehicle is notintended for hitches. Do not attach rentalhitches or other bumper-type hitches to it. Useonly a frame-mounted hitch that does notattach to the bumper.

• Will you have to make any holes in the bodyof your vehicle when you install a trailerhitch? If you do, then be sure to seal the holeslater when you remove the hitch. If you donot seal them, deadly carbon monoxide (CO)from your exhaust can get into your vehicle.See Engine Exhaust on page 125. Dirtand water can also enter the vehicle.

Safety ChainsYou should always attach chains between yourvehicle and your trailer. Cross the safetychains under the tongue of the trailer so that thetongue will not drop to the road if it becomesseparated from the hitch. Instructions about safetychains may be provided by the hitch manufactureror by the trailer manufacturer. Follow themanufacturer’s recommendation for attachingsafety chains and do not attach them to thebumper. Always leave just enough slack so youcan turn with your rig. And, never allow safetychains to drag on the ground.

Trailer BrakesDoes your trailer have its own brakes? Be sure toread and follow the instructions for the trailerbrakes so you will be able to install, adjust andmaintain them properly. Do not try to tap into yourvehicle’s brake system. If you do, both brakesystems will not work well, or at all.

Driving with a TrailerTowing a trailer requires a certain amount ofexperience. Before setting out for the open road,you will want to get to know your rig. Acquaintyourself with the feel of handling and braking withthe added weight of the trailer. And alwayskeep in mind that the vehicle you are driving isnow a good deal longer and not nearly asresponsive as your vehicle is by itself.

Before you start, check all trailer hitch parts andattachments, safety chains, electrical connector,lamps, tires and mirror adjustment. If the trailer haselectric brakes, start your vehicle and trailermoving and then apply the trailer brake controllerby hand to be sure the brakes are working.This lets you check your electrical connection atthe same time.

During your trip, check occasionally to be surethat the load is secure, and that the lamps and anytrailer brakes are still working.

Following DistanceStay at least twice as far behind the vehicle aheadas you would when driving your vehicle withouta trailer. This can help you avoid situationsthat require heavy braking and sudden turns.

PassingYou will need more passing distance up aheadwhen you are towing a trailer. And, becausethe vehicle is a good deal longer, you will need togo much farther beyond the passed vehiclebefore you can return to your lane.

Backing UpHold the bottom of the steering wheel withone hand. Then, to move the trailer to the left,just move that hand to the left. To move the trailerto the right, move your hand to the right. Alwaysback up slowly and, if possible, have someoneguide you.

Making TurnsNotice: Making very sharp turns whiletrailering could cause the trailer to come incontact with the vehicle. Your vehicle could bedamaged. Avoid making very sharp turnswhile trailering.

When you are turning with a trailer, make widerturns than normal. Do this so your trailer willnot strike soft shoulders, curbs, road signs, treesor other objects. Avoid jerky or suddenmaneuvers. Signal well in advance.

Turn Signals When Towing a TrailerWhen you tow a trailer, your vehicle may need adifferent turn signal flasher and/or extra wiring.Check with your dealer. The arrows on yourinstrument panel will flash whenever you signal aturn or lane change. Properly hooked up, thetrailer lamps will also flash, telling other drivers youare about to turn, change lanes or stop.

When towing a trailer, the arrows on yourinstrument panel will flash for turns even if the bulbson the trailer are burned out. Thus, you may thinkdrivers behind you are seeing your signal whenthey are not. It is important to check occasionally tobe sure the trailer bulbs are still working.

Driving on GradesNotice: Do not tow on steep continuousgrades exceeding 6 miles (9.6 km). Extended,higher than normal engine and transaxletemperatures may result and damage yourvehicle. Frequent stops are very important toallow the engine and transaxle to cool.

Reduce speed and shift to a lower gear beforeyou start down a long or steep downgrade. If youdo not shift down, you might have to use yourbrakes so much that they would get hot andno longer work well.

Pay attention to the engine coolant gage. If theindicator is in the red area, turn off the airconditioning to reduce engine load. See EngineOverheating on page 303.

267

Page 268: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

When towing under severe conditions such as hotambient temperatures or steep grades, yourvehicle may experience more transaxle shifting.A COOLING MODE ON message may also appearin the DIC. This alerts the driver that the shiftingmode is in progress and is aiding engine cooling.See DIC Warnings and Messages on page 180for more information.

Parking on Hills

{CAUTION:

You really should not park your vehicle,with a trailer attached, on a hill.If something goes wrong, your rig couldstart to move. People can be injured, andboth your vehicle and the trailer can bedamaged.

But if you ever have to park your rig on a hill,here is how to do it:

1. Apply your regular brakes, but do not shift intoPARK (P) for an automatic transaxle, or intogear for a manual transaxle. When parkinguphill, turn your wheels away from thecurb. When parking downhill, turn your wheelsinto the curb.

2. Have someone place chocks under the trailerwheels.

3. When the wheel chocks are in place, releasethe regular brakes until the chocks absorbthe load.

4. Reapply the regular brakes. Then apply yourparking brake, and then shift into PARK (P) foran automatic transaxle or REVERSE (R) for amanual transaxle.

5. Release the regular brakes.

268

Page 269: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

When You Are Ready to Leave AfterParking on a Hill1. Apply your regular brakes and hold the pedal

down while you:

• Start your engine.

• Shift into a gear.

• Release the parking brake.

2. Let up on the brake pedal.

3. Drive slowly until the trailer is clear of thechocks.

4. Stop and have someone pick up and storethe chocks.

Maintenance When Trailer TowingYour vehicle will need service more often whenyou are pulling a trailer. See ScheduledMaintenance on page 391 for more on this.Things that are especially important in traileroperation are transaxle fluid (do not overfill),engine oil, drive belt, cooling system and brakesystem.

Each of these is covered in this manual, and theIndex will help you find them quickly. If youare trailering, it is a good idea to review thisinformation before you start your trip.

Check periodically to see that all hitch nuts andbolts are tight.

Engine Cooling When Trailer TowingYour cooling system may temporarily overheatduring severe operating conditions. See EngineOverheating on page 303.

Gasoline OctaneIf your vehicle has the 2.2L L4 engine (VINCode F), use regular unleaded gasoline with aposted octane rating of 87 or higher. If the octanerating is less than 87, you may notice an audibleknocking noise when you drive, commonly referredto as spark knock. If this occurs, use a gasolinerated at 87 octane or higher as soon as possible. Ifyou are using gasoline rated at 87 octane orhigher and you hear heavy knocking, your engineneeds service.

If your vehicle has the 2.4L L4 engine (VIN Code B)or the 2.0L Supercharged engine (VIN Code P), usepremium unleaded gasoline with a posted octanerating of 91 or higher. You may also use regularunleaded gasoline rated at 87 octane or higher, butyour vehicle’s acceleration may be slightly reduced,and you may notice a slight audible knocking noise,commonly referred to as spark knock.

If the octane is less than 87, you may notice aheavy knocking noise when you drive. If this occurs,use a gasoline rated at 87 octane or higher as soonas possible. Otherwise, you might damage yourengine. If you are using gasoline rated at 87 octaneor higher and you hear heavy knocking, your engineneeds service.

Gasoline SpecificationsAt a minimum, gasoline should meet ASTMspecification D 4814 in the United States orCAN/CGSB-3.5 in Canada. Some gasolines maycontain an octane-enhancing additive calledmethylcyclopentadienyl manganese tricarbonyl(MMT). General Motors recommends against theuse of gasolines containing MMT. See Additiveson page 278 for additional information.

California FuelIf your vehicle is certified to meet CaliforniaEmissions Standards, it is designed to operate onfuels that meet California specifications. Seethe underhood emission control label. If this fuel isnot available in states adopting Californiaemissions standards, your vehicle will operatesatisfactorily on fuels meeting federalspecifications, but emission control systemperformance may be affected. The malfunctionindicator lamp may turn on and your vehicle mayfail a smog-check test. See Malfunction IndicatorLamp on page 170. If this occurs, return toyour authorized GM dealer for diagnosis. If it isdetermined that the condition is caused by the typeof fuel used, repairs may not be covered byyour warranty.

AdditivesTo provide cleaner air, all gasolines in the UnitedStates are now required to contain additivesthat will help prevent engine and fuel systemdeposits from forming, allowing your emissioncontrol system to work properly. In most cases,you should not have to add anything to your fuel.However, some gasolines contain only theminimum amount of additive required to meet U.S.Environmental Protection Agency regulations.To help keep fuel injectors and intake valves clean,or if your vehicle experiences problems due todirty injectors or valves, look for gasoline that isadvertised as TOP TIER Detergent Gasoline. Also,your GM dealer has additives that will helpcorrect and prevent most deposit-related problems.

Gasolines containing oxygenates, such asethers and ethanol, and reformulated gasolinesmay be available in your area. General Motorsrecommends that you use these gasolines if theycomply with the specifications described earlier.However, E85 (85% ethanol) and other fuelscontaining more than 10% ethanol must not beused in vehicles that were not designed forthose fuels.Notice: Your vehicle was not designed forfuel that contains methanol. Do not use fuelcontaining methanol. It can corrode metal partsin your fuel system and also damage the plasticand rubber parts. That damage would not becovered under your warranty.

Some gasolines that are not reformulated for lowemissions may contain an octane-enhancingadditive called methylcyclopentadienyl manganesetricarbonyl (MMT); ask the attendant where you buygasoline whether the fuel contains MMT. GeneralMotors recommends against the use of suchgasolines.

Fuels containing MMT can reduce the life of sparkplugs and the performance of the emission controlsystem may be affected. The malfunction indicatorlamp may turn on. If this occurs, return to yourauthorized GM dealer for service.

Fuels in Foreign CountriesIf you plan on driving in another country outsidethe United States or Canada, the proper fuel maybe hard to find. Never use leaded gasoline orany other fuel not recommended in the previoustext on fuel. Costly repairs caused by use ofimproper fuel would not be covered by yourwarranty.

To check the fuel availability, ask an auto club, orcontact a major oil company that does businessin the country where you will be driving.

Engine Oil

Checking Engine OilIt is a good idea to check the engine oil every timeyou get fuel. In order to get an accurate reading,the oil must be warm and the vehicle must beon level ground.

The engine oil dipstick handle is a yellow loop.See Engine Compartment Overview on page 284for the location of the engine oil dipstick.

1. Turn off the engine and give the oilseveral minutes to drain back into theoil pan. If you do not do this, the oil dipstickmight not show the actual level.

2. Pull out the dipstick and clean it with a papertowel or cloth, then push it back in all theway. Remove it again, keeping the tip down,and check the level.

What Kind of Engine Oil to UseFor Vehicles With the 2.2L or2.4L L4 Engine

Look for two things:

• GM6094M

Your vehicle’s engine requires oil meeting GMStandard GM6094M. You should look forand use only an oil that meets GM StandardGM6094M.

• SAE 5W-30

As shown in the viscosity chart, SAE 5W-30 isbest for your vehicle.These numbers on an oil container show itsviscosity, or thickness. Do not use otherviscosity oils such as SAE 20W-50.

Oils meeting theserequirements shouldalso have the starburstsymbol on thecontainer. This symbolindicates that the oilhas been certified by theAmerican PetroleumInstitute (API).

289

Page 290: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

You should look for this information on the oilcontainer, and use only those oils that areidentified as meeting GM Standard GM6094M andhave the starburst symbol on the front of the oilcontainer.

Notice: Use only engine oil identified asmeeting GM Standard GM6094M and showingthe American Petroleum Institute CertifiedFor Gasoline Engines starburst symbol. Failureto use the recommended oil can result inengine damage not covered by your warranty.

GM Goodwrench® oil meets all the requirementsfor your vehicle.

If you are in an area of extreme cold, where thetemperature falls below −20°F (−29°C), it isrecommended that you use either an SAE 5W-30synthetic oil or an SAE 0W-30 oil. Both willprovide easier cold starting and better protectionfor the engine at extremely low temperatures.

For Vehicles with the 2.0L L4Supercharged Engine Only

Look for two things:

• GM4718M

Your vehicle’s engine requires a special oilmeeting GM Standard GM4718M, suchas Mobil 1® or equivalent. Oils meeting thisstandard may be identified as synthetic.

290

Page 291: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

However, not all synthetic oils will meet thisGM standard. You should look for anduse only an oil that meets GM StandardGM4718M.

Notice: If you use oils that do not have theGM4718M Standard designation, you can causeengine damage not covered by your warranty.• SAE 5W-30

As shown in the viscosity chart, SAE 5W-30 isbest for your vehicle.These numbers on an oil container show itsviscosity, or thickness. Do not use otherviscosity oils such as SAE 20W-50.

Oils meeting theserequirements shouldalso have the starburstsymbol on thecontainer. This symbolindicates that the oilhas been certified by theAmerican PetroleumInstitute (API).

You should look for this on the oil container, anduse only those oils that are identified as meetingGM Standard GM4718M and have the starburstsymbol on the front of the oil container.

Your vehicle’s engine is filled at the factory with asynthetic oil which meets all requirements foryour vehicle.

Substitute Engine Oil: When adding oil to maintainengine oil level, oil meeting GM StandardGM4718M may not be available. You can addsubstitute oil designated SAE 5W-30 with thestarburst symbol at all temperatures. Substitute oilnot meeting GM Standard GM4718M should not beused for an oil change.

Engine Oil AdditivesDo not add anything to the oil. The recommendedoils with the starburst symbol that meet GMstandards are all you will need for goodperformance and engine protection.

Engine Oil Life System

When to Change Engine OilYour vehicle has a computer system that lets youknow when to change the engine oil and filter.This is based on engine revolutions and enginetemperature, and not on mileage. Based on drivingconditions, the mileage at which an oil changewill be indicated can vary considerably. For the oillife system to work properly, you must reset thesystem every time the oil is changed.

When the system has calculated that oil life hasbeen diminished, it will indicate that an oil changeis necessary. A CHANGE OIL SOON messagein the Driver Information Center (DIC) willcome on. See DIC Warnings and Messages onpage 180. Change your oil as soon as possiblewithin the next 600 miles (1 000 km). It is possiblethat, if you are driving under the best conditions,the oil life system may not indicate that an oilchange is necessary for over a year. However,your engine oil and filter must be changed at leastonce a year and at this time the system mustbe reset.

Your dealer has GM-trained service people whowill perform this work using genuine GM parts andreset the system. It is also important to checkyour oil regularly and keep it at the proper level.

If the system is ever reset accidentally, youmust change your oil at 3,000 miles (5 000 km)since your last oil change. Remember to reset theoil life system whenever the oil is changed.

How to Reset the Engine Oil LifeSystemThe Engine Oil Life System calculates when tochange your engine oil and filter based on vehicleuse. Anytime your oil is changed, reset thesystem so it can calculate when the next oilchange is required. If a situation occurs where youchange your oil prior to a CHANGE OIL SOONmessage being turned on, reset the system.

292

Page 293: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

After changing the engine oil, the system must bereset as follows:

1. Turn the ignition to RUN, with the engine off.

2. Press the information and reset buttonson the DIC at the same time to enter thepersonalization menu. See DIC VehiclePersonalization on page 182.

3. Press the information button to scroll throughthe available personalization menu modesuntil the DIC display shows OIL-LIFE RESET.

4. Press and hold the reset button until the DICdisplay shows ACKNOWLEDGED. This willtell you the system has been reset.

5. Turn the key to LOCK.

If the CHANGE OIL SOON message comes backon when you start your vehicle, the engine oillife system has not reset. Repeat the resetprocedure.

What to Do with Used OilUsed engine oil contains certain elements thatmay be unhealthy for your skin and couldeven cause cancer. Do not let used oil stay onyour skin for very long. Clean your skin and nailswith soap and water, or a good hand cleaner.Wash or properly dispose of clothing or ragscontaining used engine oil. See the manufacturer’swarnings about the use and disposal of oilproducts.

Used oil can be a threat to the environment. If youchange your own oil, be sure to drain all the oil fromthe filter before disposal. Never dispose of oil byputting it in the trash, pouring it on the ground, intosewers, or into streams or bodies of water. Instead,recycle it by taking it to a place that collects usedoil. If you have a problem properly disposing of yourused oil, ask your dealer, a service station, or alocal recycling center for help.

What to UseWhen you need windshield washer fluid, be sureto read the manufacturer’s instructions beforeuse. If you will be operating your vehicle in an areawhere the temperature may fall below freezing,use a fluid that has sufficient protection againstfreezing.

Adding Washer Fluid

Open the cap with thewasher symbol on it.Add washer fluiduntil the tank is full. SeeEngine CompartmentOverview on page 284for reservoir location.

Notice:• When using concentrated washer fluid,

follow the manufacturer’s instructionsfor adding water.

• Do not mix water with ready-to-use washerfluid. Water can cause the solution tofreeze and damage your washer fluid tankand other parts of the washer system.Also, water does not clean as wellas washer fluid.

• Fill your washer fluid tank onlythree-quarters full when it is very cold.This allows for expansion if freezingoccurs, which could damage the tank if itis completely full.

• Do not use engine coolant (antifreeze) inyour windshield washer. It can damageyour washer system and paint.

Brakes

Brake Fluid

The brake mastercylinder and, on manualtransaxle vehicles,the clutch hydraulicsystem use the samereservoir. The reservoiris filled with DOT-3brake fluid.

See Engine Compartment Overview on page 284for the location of the reservoir.

There are only two reasons why the brake fluidlevel in the reservoir might go down. The firstis that the brake fluid goes down to an acceptablelevel during normal brake lining wear. Whennew linings are put in, the fluid level goes backup. The other reason is that fluid is leaking out ofthe brake and/or clutch hydraulic system.

If it is, you should have the brake and/or clutchsystem fixed, since a leak means that sooneror later the brakes and/or clutch will not work well,or will not work at all.So, it is not a good idea to top off the brake/clutchfluid. Adding fluid will not correct a leak. If you addfluid when the brake linings are worn, you will havetoo much fluid when you get new brake linings. Youshould add or remove fluid, as necessary, onlywhen work is done on the brake/clutch hydraulicsystem.

{CAUTION:

If your vehicle has too much brake fluid, itcan spill on the engine. The fluid will burn ifthe engine is hot enough. You or otherscould be burned, and your vehicle could bedamaged. Add brake fluid only when workis done on the brake and/or clutchhydraulic system.

When the brake fluid falls to a low level, the brakewarning light will come on. See Brake SystemWarning Light on page 167.

313

Page 314: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

What to AddWhen you do need brake fluid, use only DOT-3brake fluid. Use new brake fluid from a sealedcontainer only. See Recommended Fluidsand Lubricants on page 402.

Always clean the brake fluid reservoir cap and thearea around the cap before removing it. Thiswill help keep dirt from entering the reservoir.

{CAUTION:

With the wrong kind of fluid in the brake/clutch system, the brakes/clutch may notwork well, or they may not even work at all.This could cause a crash. Always use theproper brake fluid.

Notice:• Using the wrong fluid can badly damage

brake/clutch system parts. For example, justa few drops of mineral-based oil, such asengine oil, in the brake/clutch hydraulicsystem can damage brake/clutch systemparts so badly that they will have to bereplaced. Do not let someone put in thewrong kind of fluid.

• If you spill brake fluid on your vehicle’spainted surfaces, the paint finish can bedamaged. Be careful not to spill brake fluidon your vehicle. If you do, wash it offimmediately. See Washing Your Vehicle onpage 372.

Brake WearYour vehicle has front disc brakes and may haverear drum brakes or rear disc brakes.

Disc brake pads have built-in wear indicators thatmake a high-pitched warning sound when thebrake pads are worn and new pads are needed.The sound may come and go or be heard allthe time your vehicle is moving, except when youare pushing on the brake pedal firmly.

314

Page 315: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

{CAUTION:

The brake wear warning sound means thatsoon the brakes will not work well. Thatcould lead to an accident. When you hearthe brake wear warning sound, have yourvehicle serviced.

Notice: Continuing to drive with worn-outbrake pads could result in costly brake repair.

Some driving conditions or climates may causea brake squeal when the brakes are first applied orlightly applied. This does not mean something iswrong with the brakes.

Properly torqued wheel nuts are necessary to helpprevent brake pulsation. When tires are rotated,inspect brake pads for wear and evenly tightenwheel nuts in the proper sequence to GM torquespecifications.

If your vehicle has rear drum brakes, they do nothave wear indicators, but if you ever hear arear brake rubbing noise, have the rear brakelinings inspected immediately.

Also, the rear brake drums should be removed andinspected each time the tires are removed forrotation or changing. When you have the frontbrake pads replaced, have the rear brakesinspected, too.

Brake linings should always be replaced ascomplete axle sets.

Brake Pedal TravelSee your dealer if the brake pedal does not returnto normal height, or if there is a rapid increase inpedal travel. This could be a sign of brake trouble.

Brake AdjustmentEvery time you make a moderate brake stop, thedisc brakes adjust for wear. If you rarely make amoderate or heavier stop, then the brakes mightnot adjust correctly. If you drive in that way,then — very carefully — make a few moderatebrake stops about every 1,000 miles (1 600 km),so the brakes will adjust properly.

If your vehicle has rear drum brakes and thebrake pedal goes down farther than normal, therear drum brakes may need adjustment. Adjustthem by backing up and firmly applying the brakesa few times.

Replacing Brake System PartsThe braking system on a vehicle is complex. Itsmany parts have to be of top quality and work welltogether if the vehicle is to have really goodbraking. Your vehicle was designed and tested withtop-quality GM brake parts. When you replace partsof the braking system — for example, when thebrake linings wear down and you need new onesput in — be sure you get new approved GMreplacement parts. If you do not, the brakes may nolonger work properly. For example, if someone putsin brake linings that are wrong for your vehicle, thebalance between the front and rear brakes canchange — for the worse. The braking performanceyou have come to expect can change in many otherways if someone puts in the wrong replacementbrake parts.

BatteryYour vehicle has a maintenance free battery.When it is time for a new battery, get one that hasthe replacement number shown on the originalbattery’s label. We recommend an ACDelco®

replacement battery.

Your vehicle’s battery is located in the trunk. Youdo not need to access the battery to jump startyour vehicle. See Jump Starting on page 317.Warning: Battery posts, terminals, and relatedaccessories contain lead and lead compounds,chemicals known to the State of Californiato cause cancer and reproductive harm. Washhands after handling.

Vehicle StorageIf you are not going to drive your vehicle for25 days or more, remove the black, negative (−)cable from the battery. This will help keepyour battery from running down.

{CAUTION:

Batteries have acid that can burn you andgas that can explode. You can be badlyhurt if you are not careful. See JumpStarting on page 317 for tips on workingaround a battery without getting hurt.

316

Page 317: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Jump StartingIf your vehicle’s battery has run down, you maywant to use another vehicle and some jumpercables to start your vehicle. Be sure to usethe following steps to do it safely.

{CAUTION:

Batteries can hurt you. They can bedangerous because:

• They contain acid that can burn you.• They contain gas that can explode or

ignite.• They contain enough electricity to

burn you.

If you do not follow these steps exactly,some or all of these things can hurt you.

Notice: Ignoring these steps could result incostly damage to your vehicle that would not becovered by your warranty.Trying to start your vehicle by pushing orpulling it will not work, and it could damageyour vehicle.1. Check the other vehicle. It must have a 12-volt

battery with a negative ground system.

Notice: If the other vehicle’s system is not a12-volt system with a negative ground, bothvehicles can be damaged. Only use vehicleswith 12-volt systems with negative grounds tojump start your vehicle.2. Get the vehicles close enough so the jumper

cables can reach, but be sure the vehicles arenot touching each other. If they are, it couldcause a ground connection you do not want.You would not be able to start your vehicle, andthe bad grounding could damage the electricalsystems.To avoid the possibility of the vehicles rolling,set the parking brake firmly on both vehiclesinvolved in the jump start procedure. Put anautomatic transaxle in PARK (P) or a manualtransaxle in NEUTRAL before setting theparking brake.

{CAUTION:

Using a match near a battery can causebattery gas to explode. People have beenhurt doing this, and some have beenblinded. Use a flashlight if you need morelight.

Be sure the battery has enough water. Youdo not need to add water to the batteryinstalled in your new vehicle. But if abattery has filler caps, be sure the rightamount of fluid is there. If it is low, addwater to take care of that first. If you don’t,explosive gas could be present.

Battery fluid contains acid that can burnyou. Do not get it on you. If youaccidentally get it in your eyes or on yourskin, flush the place with water and getmedical help immediately.

{CAUTION:

Fans or other moving engine parts caninjure you badly. Keep your hands awayfrom moving parts once the engine isrunning.

5. Check that the jumper cables do not haveloose or missing insulation. If they do, youcould get a shock. The vehicles couldbe damaged too.Before you connect the cables, here are somebasic things you should know. Positive (+)will go to positive (+) or to a remote positive (+)terminal if the vehicle has one. Negative (−)will go to a heavy, unpainted metal engine partor to a remote negative (−) terminal if thevehicle has one.

320

Headlamp AimingThe vehicle has a visual optical headlamp aimingsystem. The aim has been preset at the factoryand should need no further adjustment

However, If the vehicle is damaged in an accident,the headlamp aim may be affected and adjustmentmay be necessary.

If oncoming vehicles flash their high beams atyou, this may also mean the vertical aim needs tobe adjusted.

It is recommended that the vehicle is taken to yourdealer for service if the headlamps need to bere-aimed. It is possible however, to re-aimthe headlamps as described in the followingprocedure.

The vehicle should be properly prepared asfollows:

• The vehicle should be placed so theheadlamps are 25 ft. (7.6 m) from a lightcolored wall.

• The vehicle must have all four tires on aperfectly level surface which is level allthe way to the wall.

• The vehicle should be placed so it isperpendicular to the wall.

• The vehicle should not have any snow, ice ormud on it.

• The vehicle should be fully assembled and allother work stopped while headlamp aiming isbeing done.

• The vehicle should be normally loaded with afull tank of fuel and one person or 160 lbs(75 kg) on the driver’s seat.

• Tires should be properly inflated.

Headlamp aiming is done with the vehicle’slow-beam headlamps. The high-beam headlampswill be correctly aimed if the low-beam headlampsare aimed properly.

The vertical headlamp aiming screws are locatedunder the hood near the headlamps.

323

Low-Profile Performance TireIf your vehicle has 215/45R18 size tires, they areclassified as low-profile performance tires. Thesetires are designed for very responsive driving onwet or dry pavement. You may also notice moreroad noise with low-profile performance tires andthat they tend to wear faster.

Notice: If your vehicle has low-profile tires,they are more susceptible to damage from roadhazards or curb impact than standard profiletires. Tire and/or wheel assembly damage canoccur when coming into contact with roadhazards like, potholes, or sharp edged objects,or when sliding into a curb. Your GM warrantydoes not cover this type of damage. Keep tiresset to the correct inflation pressure and, whenpossible avoid contact with curbs, potholes,and other road hazards.

Winter TiresIf your vehicle has 215/45R18 size tires, they areclassified as low-profile performance tires. Thesetires are designed for very responsive driving onwet or dry pavement. If you expect to drive on snowor ice covered roads often, you may want to getwinter tires for your vehicle.

All season tires provide good overall performanceon most surfaces but they may not offer the tractionyou would like or the same level of performance aswinter tires on snow or ice covered roads.Winter tires, in general, are designed for increasedtraction on snow and ice covered roads. With wintertires, there may be decreased dry road traction,increased road noise, and shorter tire tread life.After switching to winter tires, be alert for changesin vehicle handling and braking.See your dealer for details regarding winter tireavailability and proper tire selection. Also, seeBuying New Tires on page 347.

If you choose to use winter tires:

• Use tires of the same brand and tread type onall four wheel positions.

• Use only radial ply tires of the same size, loadrange, and speed rating as your originalequipment tires.

Winter tires with the same speed rating as youroriginal equipment tires may not be available for H,V, W, Y and ZR speed rated tires. If you choosewinter tires with a lower speed rating, neverexceed the tire’s maximum speed capability.

A Tire and Loading Information label is attached tothe vehicle’s center pillar (B-pillar). This label showsyour vehicle’s original equipment tires and thecorrect inflation pressures for your tires when theyare cold. The recommended cold tire inflationpressure, shown on the label, is the minimumamount of air pressure needed to support yourvehicle’s maximum load carrying capacity.

For additional information regarding how muchweight your vehicle can carry, and an example ofthe Tire and Loading Information label, seeLoading Your Vehicle on page 253. How you loadyour vehicle affects vehicle handling and ridecomfort. Never load your vehicle with more weightthan it was designed to carry.

When to CheckCheck your tires once a month or more. Do notforget to check the compact spare tire, it should beat 60 psi (420 kPa). For additional informationregarding the compact spare tire, see CompactSpare Tire on page 368.

How to CheckUse a good quality pocket-type gage to check tirepressure. You cannot tell if your tires areproperly inflated simply by looking at them. Radialtires may look properly inflated even when theyare under-inflated. Check the tire’s inflationpressure when the tires are cold. Cold means yourvehicle has been sitting for at least three hoursor driven no more than 1 mile (1.6 km).

Remove the valve cap from the tire valve stem.Press the tire gage firmly onto the valve toget a pressure measurement. If the cold tireinflation pressure matches the recommendedpressure on the Tire and Loading Informationlabel, no further adjustment is necessary. If theinflation pressure is low, add air until you reach therecommended amount.

If you overfill the tire, release air by pushing onthe metal stem in the center of the tire valve.Re-check the tire pressure with the tire gage.

Be sure to put the valve caps back on the valvestems. They help prevent leaks by keeping out dirtand moisture.

High-Speed Operation

{CAUTION:

Driving at high speeds, 100 mph (160 km/h)or higher, puts an additional strain on tires.Sustained high-speed driving causesexcessive heat build up and can causesudden tire failure. You could have a crashand you or others could be killed. Somehigh-speed rated tires require inflationpressure adjustment for high speedoperation. When speed limits and roadconditions are such that a vehicle can bedriven at high speeds, make sure the tiresare rated for high speed operation, inexcellent condition, and set to thecorrect cold tire inflation pressure forthe vehicle load.

If your vehicle has 215/45R18 size tires, they willrequire inflation pressure adjustment when drivingyour vehicle at speeds of 100 mph (160 km/h) orhigher. Set the cold tire inflation pressure to35 psi (241 kPa) for the front and rear tires, whenoperating your vehicle at high-speed conditions.When you end high-speed driving, return the tires tothe cold inflation pressure shown on the Tire andLoading Information label. See Loading YourVehicle on page 253 and Inflation - Tire Pressureon page 342.

You need a new tire if any of the followingstatements are true:

• You can see the indicators at three or moreplaces around the tire.

• You can see cord or fabric showing throughthe tire’s rubber.

• The tread or sidewall is cracked, cut, orsnagged deep enough to show cord or fabric.

• The tire has a bump, bulge, or split.

• The tire has a puncture, cut, or other damagethat cannot be repaired well because of thesize or location of the damage.

Buying New TiresGM has developed and matched specific tires foryour vehicle. The original equipment tiresinstalled on your vehicle, when it was new, weredesigned to meet General Motors TirePerformance Criteria Specification (TPC spec)system rating. If you need replacement tires, GMstrongly recommends that you get tires withthe same TPC Spec rating. This way, your vehiclewill continue to have tires that are designed togive the same performance and vehicle safety,during normal use, as the original tires.

GM’s exclusive TPC Spec system considers overa dozen critical specifications that impact theoverall performance of your vehicle, includingbrake system performance, ride and handling,traction control, and tire pressure monitoringperformance. GM’s TPC Spec number is moldedonto the tire’s sidewall by the tire manufacturer.If the tires have an all-season tread design,the TPC spec number is followed by an MS formud and snow. See Tire Sidewall Labelingon page 336 for additional information.

Winter tires with the same speed rating as youroriginal equipment tires may not be available for H,V, W, Y, and ZR speed rated tires. If you choosewinter tires with a lower speed rating, neverexceed the tire’s maximum speed capability.

{CAUTION:

Mixing tires could cause you to losecontrol while driving. If you mix tires ofdifferent sizes, brands, or types (radialand bias-belted tires), the vehicle may nothandle properly, and you could have acrash. Using tires of different sizes,brands, or types may also cause damageto your vehicle. Be sure to use the correctsize, brand, and type of tires on allwheels. It is all right to drive with yourcompact spare temporarily, as it wasdeveloped for use on your vehicle. SeeCompact Spare Tire on page 368.

{CAUTION:

If you use bias-ply tires on your vehicle,the wheel rim flanges could developcracks after many miles of driving. A tireand/or wheel could fail suddenly, causinga crash. Use only radial-ply tires with thewheels on your vehicle.

If you must replace your vehicle’s tires with thosethat do not have a TPC Spec number, makesure they are the same size, load range, speedrating, and construction type (radial andbias-belted tires) as your vehicle’s original tires.

Your vehicle’s original equipment tires are listed onthe Tire and Loading Information label. Thislabel is attached to the vehicle’s center pillar(B-pillar). See Loading Your Vehicle on page 253,for more information about the Tire and LoadingInformation Label and its location on your vehicle.

Uniform Tire Quality GradingQuality grades can be found where applicable onthe tire sidewall between tread shoulder andmaximum section width. For example:

Treadwear 200 Traction AA Temperature AThe following information relates to the systemdeveloped by the United States National HighwayTraffic Safety Administration (NHTSA), whichgrades tires by treadwear, traction, andtemperature performance. This applies only tovehicles sold in the United States. The grades aremolded on the sidewalls of most passenger cartires. The Uniform Tire Quality Grading (UTQG)system does not apply to deep tread, winter-typesnow tires, space-saver, or temporary usespare tires, tires with nominal rim diameters of10 to 12 inches (25 to 30 cm), or to somelimited-production tires.

While the tires available on General Motorspassenger cars and light trucks may vary withrespect to these grades, they must also conformto federal safety requirements and additionalGeneral Motors Tire Performance Criteria (TPC)standards.

TreadwearThe treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and a half (1.5) timesas well on the government course as a tiregraded 100. The relative performance of tiresdepends upon the actual conditions of their use,however, and may depart significantly fromthe norm due to variations in driving habits, servicepractices, and differences in road characteristicsand climate.

Traction – AA, A, B, CThe traction grades, from highest to lowest, areAA, A, B, and C. Those grades represent the tire’sability to stop on wet pavement as measuredunder controlled conditions on specifiedgovernment test surfaces of asphalt and concrete.A tire marked C may have poor tractionperformance.

Warning: The traction grade assigned to this tireis based on straight-ahead braking tractiontests, and does not include acceleration, cornering,hydroplaning, or peak traction characteristics.

350

Page 351: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Temperature – A, B, CThe temperature grades are A (the highest), B,and C, representing the tire’s resistance tothe generation of heat and its ability to dissipateheat when tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of the tireto degenerate and reduce tire life, and excessivetemperature can lead to sudden tire failure.The grade C corresponds to a level of performancewhich all passenger car tires must meet underthe Federal Motor Vehicle Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheelthan the minimum required by law.

Warning: The temperature grade for this tire isestablished for a tire that is properly inflatedand not overloaded. Excessive speed,underinflation, or excessive loading, eitherseparately or in combination, can cause heatbuildup and possible tire failure.

Wheel Alignment and Tire BalanceThe tires and wheels on your vehicle were alignedand balanced carefully at the factory to give youthe longest tire life and best overall performance.Adjustments to wheel alignment and tirebalancing will not be necessary on a regular basis.However, if you notice unusual tire wear or yourvehicle pulling to one side or the other, thealignment may need to be checked. If you noticeyour vehicle vibrating when driving on a smoothroad, your tires and wheels may need to berebalanced. See your dealer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent, cracked, or badlyrusted or corroded. If wheel nuts keep comingloose, the wheel, wheel bolts, and wheelnuts should be replaced. If the wheel leaks air,replace it (except some aluminum wheels,which can sometimes be repaired). See yourdealer if any of these conditions exist.

Your dealer will know the kind of wheel you need.

351

Page 352: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Each new wheel should have the sameload-carrying capacity, diameter, width, offsetand be mounted the same way as the oneit replaces.

If you need to replace any of your wheels, wheelbolts, or wheel nuts, replace them only withnew GM original equipment parts. This way, youwill be sure to have the right wheel, wheelbolts, and wheel nuts for your vehicle.

{CAUTION:

Using the wrong replacement wheels,wheel bolts, or wheel nuts on your vehiclecan be dangerous. It could affect thebraking and handling of your vehicle,make your tires lose air and make youlose control. You could have a collision inwhich you or others could be injured.Always use the correct wheel, wheel bolts,and wheel nuts for replacement.

Notice: The wrong wheel can also causeproblems with bearing life, brake cooling,speedometer or odometer calibration,headlamp aim, bumper height, vehicle groundclearance, and tire or tire chain clearanceto the body and chassis.

See Changing a Flat Tire on page 355 for moreinformation.

Used Replacement Wheels

{CAUTION:

Putting a used wheel on your vehicle isdangerous. You cannot know how it hasbeen used or how far it has been driven. Itcould fail suddenly and cause a crash. Ifyou have to replace a wheel, use a newGM original equipment wheel.

If a Tire Goes FlatIt is unusual for a tire to blowout while you aredriving, especially if you maintain your vehicle’stires properly. If air goes out of a tire, it ismuch more likely to leak out slowly. But if youshould ever have a blowout, here are a few tipsabout what to expect and what to do:

If a front tire fails, the flat tire will create a dragthat pulls the vehicle toward that side. Take yourfoot off the accelerator pedal and grip thesteering wheel firmly. Steer to maintain laneposition, and then gently brake to a stop well outof the traffic lane.

A rear blowout, particularly on a curve, acts muchlike a skid and may require the same correctionyou would use in a skid. In any rear blowoutremove your foot from the accelerator pedal. Getthe vehicle under control by steering the wayyou want the vehicle to go. It may be very bumpyand noisy, but you can still steer. Gently braketo a stop, well off the road if possible.

{CAUTION:

Lifting a vehicle and getting under it to domaintenance or repairs is dangerouswithout the appropriate safety equipmentand training. The jack provided with yourvehicle is designed only for changing aflat tire. If it is used for anything else, youor others could be badly injured or killedif the vehicle slips off the jack.

Headlamp WiringThe headlamp wiring is protected by fuses. Shouldyour headlamps fail to function, have yourheadlamp system checked right away.

Windshield Wiper FusesThe windshield wiper motor is protected by acircuit breaker and a fuse. If the motor overheatsdue to heavy snow or ice, the wiper will stopuntil the motor cools. If the overload is caused bysome electrical problem, have it fixed.

Power Windows and Other PowerOptionsFuses in the fuse block protect the power windows.When the current load is too heavy, the fuse opensprotecting the circuit until the problem is fixed.

Fuses and Circuit BreakersThe wiring circuits in your vehicle are protectedfrom short circuits by a combination of fuses,circuit breakers and fusible thermal links.This greatly reduces the chance of damagecaused by electrical problems.

Look at the silver-colored band inside the fuse. Ifthe band is broken or melted, replace the fuse.Be sure you replace a bad fuse with a new one ofthe identical size and rating.

If you ever have a problem on the road and do nothave a spare fuse, you can “borrow” one thathas the same amperage. Just pick some featureof your vehicle that you can get alongwithout — like the radio or cigarette lighter — anduse its fuse if it is the correct amperage.Replace it as soon as you can.

There are two fuse blocks in your vehicle: the floorconsole fuse block and the engine compartmentfuse block.

There is one additional fuse located in the back ofthe vehicle near the battery.

Vehicle Data Collection and EventData RecordersYour vehicle, like other modern motor vehicles,has a number of sophisticated computer systemsthat monitor and control several aspects of thevehicle’s performance. Your vehicle uses on-boardvehicle computers to monitor emission controlcomponents to optimize fuel economy, to monitorconditions for airbag deployment and, if thevehicle has the Anti-lock Brake System (ABS),to provide anti-lock braking and to help the drivercontrol the vehicle in difficult driving situations.Some information may be stored during regularoperations to facilitate repair of detectedmalfunctions; other information is stored only in acrash event by computer systems, such as thosecommonly called Event Data Recorders (EDR).

In a crash event, computer systems, such as theairbag Sensing and Diagnostic Module (SDM)in your vehicle may record information about thecondition of the vehicle and how it was operated,such as data related to engine speed, brakeapplication, throttle position, vehicle speed, safetybelt usage, airbag readiness, airbag performance,and the severity of a collision.

This information has been used to improve vehiclecrash performance and may be used to improvecrash performance of future vehicles anddriving safety. Unlike the data recorders on manyairplanes, these on-board systems do notrecord sounds, such as conversation of vehicleoccupants.

To read this information, special equipment isneeded and access to the vehicle or the devicethat stores the data is required. GM will not accessinformation about a crash event or share it withothers other than:

• with the consent of the vehicle owner or, if thevehicle is leased, with the consent of thelessee,

• in response to an official request of police orsimilar government office,

• as part of GM’s defense of litigation throughthe discovery process, or

• as required by law.

422

Page 423: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

In addition, once GM collects or receives data,GM may:

• use the data for GM research needs,

• make it available for research whereappropriate confidentiality is to be maintainedand need is shown, or

• share summary data which is not tied to aspecific vehicle with non-GM organizationsfor research purposes.

Others, such as law enforcement, may haveaccess to the special equipment that can read theinformation if they have access to the vehicleor the device that stores the data.

If your vehicle has OnStar®, please check theOnStar® subscription service agreement or manualfor information on its operations and datacollection.

Collision Damage RepairIf your vehicle is involved in a collision and it isdamaged, have the damage repaired by a qualifiedtechnician using the proper equipment andquality replacement parts. Poorly performedcollision repairs will diminish your vehicle’s resalevalue, and safety performance can becompromised in subsequent collisions.

Collision PartsGenuine GM Collision parts are new parts madewith the same materials and construction methodsas the parts with which your vehicle wasoriginally built. Genuine GM Collision parts areyour best choice to assure that your vehicle’sdesigned appearance, durability, and safety arepreserved. The use of Genuine GM parts can helpmaintain your GM New Vehicle Warranty.

423

Page 424: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

Recycled original equipment parts may alsobe used for repair. These parts are typicallyremoved from vehicles that were total losses inprior accidents. In most cases, the parts beingrecycled are from undamaged sections of thevehicle. A recycled original equipment GM part,may be an acceptable choice to maintain yourvehicle’s originally designed appearance and safetyperformance, however, the history of these parts isnot known. Such parts are not covered by yourGM New Vehicle Limited Warranty, and any relatedfailures are not covered by that warranty.

Aftermarket collision parts are also available.These are made by companies other than GMand may not have been tested for your vehicle.As a result, these parts may fit poorly, exhibitpremature durability/corrosion problems, and maynot perform properly in subsequent collisions.Aftermarket parts are not covered by your GM NewVehicle Limited Warranty, and any vehiclefailure related to such parts are not covered bythat warranty.

Repair FacilityGM also recommends that you choose a collisionrepair facility that meets your needs before you everneed collision repairs. Your GM dealer may have acollision repair center with GM-trained techniciansand state of the art equipment, or be able torecommend a collision repair center that hasGM-trained technicians and comparableequipment.

Insuring Your VehicleProtect your investment in your GM vehicle withcomprehensive and collision insurance coverage.There are significant differences in the qualityof coverage afforded by various insurance policyterms. Many insurance policies provide reducedprotection to your GM vehicle by limitingcompensation for damage repairs by usingaftermarket collision parts. Some insurancecompanies will not specify aftermarket collisionparts. When purchasing insurance, we recommendthat you assure your vehicle will be repairedwith GM original equipment collision parts. If suchinsurance coverage is not available from yourcurrent insurance carrier, consider switchingto another insurance carrier.

424

If your vehicle is leased, the leasing companymay require you to have insurance that assuresrepairs with Genuine GM Original EquipmentManufacturer (OEM) parts or GenuineManufacturer replacement parts. Read yourlease carefully, as you may be charged at the endof your lease for poor quality repairs.

If an Accident OccursHere is what to do if you are involved in anaccident.

• Try to relax and then check to make sure youare all right. If you are uninjured, make surethat no one else in your vehicle, or theother vehicle, is injured.

• If there has been an injury, call 911 for help.Do not leave the scene of an accident untilall matters have been taken care of. Moveyour vehicle only if its position puts youin danger or you are instructed to move it by apolice officer.

• Give only the necessary and requestedinformation to police and other parties involvedin the accident. Do not discuss your personalcondition, mental frame of mind, or anythingunrelated to the accident. This will help guardagainst post-accident legal action.

• If you need roadside assistance, callGM Roadside Assistance. See RoadsideAssistance Program on page 416 for moreinformation.

• If your vehicle cannot be driven, know wherethe towing service will be taking it. Get acard from the tow truck operator or write downthe driver’s name, the service’s name, andthe phone number.

• Remove any valuables from your vehiclebefore it is towed away. Make sure thisincludes your insurance information andregistration if you keep these items inyour vehicle.

425

Page 426: 2007 Chevrolet Cobalt Owner Manual M - Vaden · PDF file2007 Chevrolet Cobalt Owner Manual M 1. Service and Appearance Care ... Maintenance Schedule ..... 388 Customer Assistance Information

• Gather the important information you willneed from the other driver. Things like name,address, phone number, driver’s licensenumber, vehicle license plate, vehicle make,model and model year, Vehicle IdentificationNumber (VIN), insurance company andpolicy number, and a general description ofthe damage to the other vehicle.

• If possible, call your insurance company fromthe scene of the accident. They will walk youthrough the information they will need. Ifthey ask for a police report, phone or go tothe police department headquarters thenext day and you can get a copy of the reportfor a nominal fee. In some states/provinceswith “no fault” insurance laws, a report may notbe necessary. This is especially true if thereare no injuries and both vehicles are driveable.

• Choose a reputable collision repair facility foryour vehicle. Whether you select a GM dealeror a private collision repair facility to fix thedamage, make sure you are comfortable withthem. Remember, you will have to feelcomfortable with their work for a long time.

• Once you have an estimate, read it carefullyand make sure you understand what work willbe performed on your vehicle. If you have aquestion, ask for an explanation. Reputableshops welcome this opportunity.

Managing the Vehicle DamageRepair ProcessIn the event that your vehicle requires damagerepairs, GM recommends that you take an activerole in its repair. If you have a pre-determined repairfacility of choice, take your vehicle there, or have ittowed there. Specify to the facility that any requiredreplacement collision parts be original equipmentparts, either new Genuine GM parts or recycledoriginal GM parts. Remember, recycled parts willnot be covered by your GM vehicle warranty.

Insurance pays the bill for the repair, but you mustlive with the repair. Depending on your policy limits,your insurance company may initially value therepair using aftermarket parts. Discuss this withyour repair professional, and insist on GenuineGM parts. Remember if your vehicle is leased youmay be obligated to have the vehicle repaired withGenuine GM parts, even if your insurance coveragedoes not pay the full cost.

If another party’s insurance company is paying forthe repairs, you are not obligated to accept arepair valuation based on that insurancecompany’s collision policy repair limits, as youhave no contractual limits with that company. Insuch cases, you can have control of the repair andparts choices as long as cost stays withinreasonable limits.
