Airbag System

Questions and AnswersAbout Airbags andSpecialty LawEnforcement VehiclesQ: Can equipment such as radar

devices, video cameras, andradio trees be mounted in aspecialty vehicle equippedwith a right front passengerfrontal airbag?

A: Yes, but care must be taken toproperly mount the equipmentoutside of the airbag“deployment zone.”

Q: What is the airbag“deployment zone”?

A: The term “deployment zone”describes the space an airbagtakes up when fully inflated.Airbags need room to workproperly, and anything in the“deployment zone” — suchas improperly mountedequipment — can greatly affectthe performance of the airbag.

{ Warning

Airbags inflate with great force,faster than the blink of an eye. Noobjects, such as shotguns, shouldbe placed over or near the airbagcovers. Equipment mounted tooclose to an inflating airbag couldprevent the airbag from operatingproperly to protect the occupantsor could be forced into anoccupant or break and become adangerous projectile, causingsevere injury or even death. Tohelp prevent injury and to allowthe airbag to perform as it wasdesigned, do not mountequipment inside the airbagdeployment zones.


8 Seats and Restraints

Q: How can I identify the airbag“deployment zone” in myvehicle?

A: See Airbag DeploymentDiagrams 0 10 for moreinformation. The diagramsprovide the approximatedimensions of the “deploymentzones” for your specialty vehicle.Before doing any service work,including the installation of anyequipment, consult theappropriate service manual.

Q: Is it possible to shieldequipment so it does notinterfere with airbagdeployment?

A: While shielding may protectcertain equipment from beingdamaged or dislodged, it mayalso negatively affect how anairbag inflates. Therefore, wecannot recommend theplacement of any equipment inthe deployment zone, evenwhen shielding.

Q: Can the installation of pushbumpers on the front end ofthe vehicle affect thedeployment of the airbag?

A: It is not likely that installing pushbumpers will affect sensing forthe airbag as long as the vehiclestructure itself is not modified.On pickup models, push bumperstyles with vertical pushingmembers that are in fore-aftalignment with the front airbagsensors are not recommended.GM is not aware of any adversedefects from the many pushbumpers that have beeninstalled on current model GMpolice vehicles with airbags.

See “Adding Equipment to theAirbag-Equipped Vehicle” in theowner manual for more information.

Customer-InstalledEquipmentBefore installing equipment, readthe following.

{ Warning

Do not install equipment in theinflation path of any airbag. Theequipment may interfere with thedeployment of the airbag, maydamage the airbag, or otherwisebe damaged or forced into anoccupant, all of which may causesevere injury or even death.

Do not attach anything to thesteering wheel hub or mount anyequipment within the deploymentzone for the driver airbag.

Do not mount equipment on thepassenger side of the instrumentpanel top pad deployment zone.Equipment should not bemounted on or around thepassenger airbag openingbecause of a deploying airbag.

Driving Information

Vehicle Load LimitsThe information in this section of thesupplement is for those who intendto install additional equipment to thepolice vehicle after it has left thefactory, and for those who will bedriving and loading the vehicle withpassengers and/or cargo.

Two labels on your vehicle showhow much weight it was designed tocarry, the Tire and LoadingInformation label and theCertification/Tire label. These labelsare attached to your vehicle andgive you the maximum loadcapacity, the Gross Vehicle WeightRating (GVWR) and the Gross AxleWeight Rating (GAWR) for yourvehicle. See “Vehicle Load Limits” inthe owner manual for additionalloading information.

The following guidelines can helpyou with proper loading and loaddistribution when installingadditional equipment on the TahoePolice Package and Tahoe andSilverado Special ServicePackages.

{ Warning

Do not load the vehicle anyheavier than the GrossVehicle Weight Rating(GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoreduce stopping distance,damage the tires, and shortenthe life of the vehicle.


Driving and Operating 25

Adding Equipment to YourVehicle

Before adding accessories orequipment to your police vehicle,there are some things you needto know:

. The police vehicle's maximumcapacity weight.

. The weight of your policevehicle, including a full tank offuel but without a driver andpassengers.

. The weight of items you plan onadding to your police vehicle,like roof mounted light bar(s),push bumpers, securitybarrier(s), rear storageorganizer, highway flares, fireextinguishers, weapons,ammunition, radios, and videoequipment.

. The weight and number ofpassengers you intend to carryin your vehicle.

. The total weight of anyadditional cargo you intend tocarry in your vehicle.

When planning your vehicleequipment installation, remembernot to exceed the Gross VehicleWeight Rating (GVWR) or the GrossAxle Weight Rating (GAWR) of thefront or rear axles. To keep theavailable load weight less than thevehicle capacity weight, you mayneed to limit the number ofpassengers you carry in yourvehicle or change your choice ofadditional equipment.

Center of Gravity (CG)

A vehicle's center of gravity is animaginary location inside the vehicleand is a balance point for thevehicle mass as it moves down theroad. The police vehicle's center ofgravity, before you add a load andpassengers, is approximatelymidway between the center of theaxles, up from the ground to justbelow the front window, andbetween the driver and passenger.

Equipment location and weight onthe vehicle's center of gravity isimportant to keep in mind whenplanning an installation. Heavyequipment should be positioned as

low and as far forward in the rearload compartment as possible. Tryto mount the equipment below thebottom of the side windows. Referto the Loading Zone chart anddiagram to help with yourinstallation plan.

A procedure to make the necessarymeasurements and formulas tocalculate the vehicle longitudinal,lateral, and vertical position of thecenter of gravity can be found in theGM Coachbuilders Manual.Equipment required to conduct themeasurements for calculating thecenter of gravity are:

. Weight scales of sufficientcapacity to measure the vehicleweight at each wheel.

. A post-type hoist or other meansto safely elevate the front of thevehicle to at least an angle of20 degrees above horizontal.

See your GM dealer to get moreinformation about this coachbuilderprocedure.



Keeping the center of gravitymidway between the axles is alsoimportant to provide proper brakingperformance. About half the totalvehicle weight on each axle isrecommended.

Weigh your vehicle after theadditional equipment has beeninstalled to determine the actualweight of your vehicle. Weigh thevehicle with a full tank of fuel andwithout passengers. You may needto put a limit on how many people orother equipment you can carryinside your vehicle after theadditional equipment has beeninstalled.

Starting andOperating

Fast Idle SystemWhile parked with the engine idlingfor an extended period, turn off thefollowing factory equipment ifemergency lighting andcommunication equipment areoperating:

. Air Conditioner

. Fan

. Rear Window Defogger

. Factory Audio System

See “Running the Vehicle WhileParked” in the owner manual.

Engine Idle Speed - AlternatorOutput

Normal idle speed for the engine isset for 600 rpm. To increasealternator output while thetransmission remains in P (Park) orN (Neutral), and the electrical loadon the alternator is large enough,the engine idle speed can rise to ashigh as 800 to 1000 rpm.



Fuel

E85 or FlexFuel

Fleet Fuel Use

For fleets that use only E85 orFlexFuel, occasionally filling thetank with gasoline will help keep thefuel system clean.

Filling the Tank

{ Warning

Fuel vapors and fuel fires burnviolently and can cause injury ordeath.

. To help avoid injuries to youand others, read and followall the instructions on thefuel pump island.

. Turn off the engine whenrefueling.

. Keep sparks, flames, andsmoking materials awayfrom fuel.

(Continued)

Warning (Continued)

. Do not leave the fuel pumpunattended.

. Do not use a cell phonewhile refueling.

. Do not reenter the vehiclewhile pumping fuel.

. Keep children away fromthe fuel pump and never letchildren pump fuel.

. Fuel can spray out if the fuelcap is opened too quickly.This spray can happen if thetank is nearly full, and ismore likely in hot weather.Open the fuel cap slowlyand wait for any hiss noiseto stop then unscrew thecap all the way.

The fuel cap is behind a hinged fueldoor on the driver side of thevehicle. If the vehicle has E85 fuelcapability, the fuel cap will be yellowand state that E85 or gasoline canbe used. See E85 or FlexFuel 0 28.

To open the fuel door, push andrelease the rearward center edge ofthe door.

To remove the fuel cap, turn itslowly counterclockwise. Whilerefueling, hang the tethered fuel capfrom the hook on the fuel door.

Be careful not to spill fuel. Do nottop off or overfill the tank. Wait afew seconds after you have finishedpumping before removing thenozzle. Clean fuel from paintedsurfaces as soon as possible. See“Exterior Care” in the owner manual.

When replacing the fuel cap, turnthe fuel cap clockwise until it clicks.It will require more effort to turn the



fuel cap on the last turn as youtighten it. Make sure the cap is fullyinstalled. The diagnostic system candetermine if the fuel cap has beenleft off or improperly installed. Thiswould allow fuel to evaporate intothe atmosphere. See “MalfunctionIndicator Lamp” in the ownermanual.

The TIGHTEN GAS CAP messagedisplays if the fuel cap is notproperly installed.

{ Warning

If a fire starts while you arerefueling, do not remove thenozzle. Shut off the flow of fuel byshutting off the pump or bynotifying the station attendant.Leave the area immediately.

Caution

If a new fuel cap is needed, besure to get the right type of capfrom your dealer. The wrong typeof fuel cap may not fit properly,may cause the malfunctionindicator lamp to light, and coulddamage the fuel tank andemissions system. See“Malfunction Indicator Lamp” inthe owner manual.

Towing

Trailer TowingFor more information, see “TrailerTowing” in the owner manual.

Weight of the Trailer

How heavy can a trailer safely be?

It depends on how the rig is used.For example, speed, altitude, roadgrades, outside temperature andhow much the vehicle is used to pulla trailer are all important. It candepend on any special equipmenton the vehicle, and the amount oftongue weight the vehicle can carry.

Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment.The weight of additional optionalequipment, passengers, andcargo in the tow vehicle must besubtracted from the maximum trailerweight.



For Tahoe Police and SpecialService Package vehicles, theTrailer Weight Rating (TWR) iscalculated assuming the tow vehiclehas only the driver and all requiredtrailering equipment. Weight ofadditional optional equipment,passengers, and cargo in the towvehicle must be subtracted from thetrailer weight rating.

For Silverado Special ServicePackage vehicles, the Trailer weightrating (TWR) is calculated assumingthe tow vehicle has the driver, afront seat passenger, and allrequired trailering equipment.Weight of additional optionalequipment, passengers, and cargoin the tow vehicle must besubtracted from the trailer weightrating.

Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle modeland options.
