Catalytic Converter

Your MERCEDES-BENZ is equippedwith monolithic type catalytic converters,an important element in conjunction withthe oxygen sensor to achieve substantialcontrol of the pollutants in the exhaustemissions. Keep your vehicle in properoperating condition by following our re-commended maintenance instructions asoutlined in your Maintenance Booklet.

Caution!

To prevent damage to the catalyticconverters, use only premium unleadedgasoline in this vehicle.

Any noticeable irregularities in engineoperation should be repaired promptly.Otherwise, excessive unburned fuelmay reach the catalytic convertercausing it to overheat.

Warning!

As with any vehicle, do not idle, parkor operate this vehicle in areas wherecombustible materials such as grass,hay or leaves can come into contactwith the hot exhaust system, as thesematerials could be ignited.

15

Starting and Turning off the Engine

Before Starting

Engage parking brake and ensuregearshift lever is in neutral (selectorlever position "P" or “N” on automatictransmissions).Turn key in steering lock to position 2.The charge indicator lamp should comeon.

Cold Engine

Do not depress accelerator.Turn key in steering lock clock-wise tothe stop. Do not depress accelerator.Release key only when the engine isfiring regularly.

Hot Engine

Do not depress accelerator. Turn key insteering lock clock-wise to the stop. Ifthe engine has not fired after approx. 4seconds, depress accelerator andcontinue cranking until the engine isfiring regularly. Release key and backoff accelerator.At very high coolant temperatures theengine starting time can be shortened ifthe accelerator is depressed slowly atthe beginning of the starting process.

Turning Off

Turn the key in the steering lock toposition 0 to stop the engine.Note:Vehicles with automatic transmission:the key can only be removed with theselector lever in position "P".If the coolant temperature is very high(e.g. after hard driving on mountainroads), do not shut off the engineimmediately, but allow it to run for 1-2minutes at increased idle speed withselector lever in position "P" or "N".

Important!

Due to the installed starter non-repeatfeature, the key must be turnedcompletely to the left before attemptingto start the engine again.

Observe the oil pressure gaugeimmediately after starting the engine.In a very cold engine the oil pressurewill rise slowly after the engine hasstarted. Do not speed up the enginebefore pressure is registered on thepressure gauge. If you do not see thegauge register oil pressure, stop theengine and have it checked.

The battery charge indicator lampshould go out as soon as the engine hasstarted.

In areas where temperatures frequentlydrop below -4°F (-20°C) werecommend that an engine block heaterbe installed. Your authorizedMercedes-Benz dealer will advise youon this subject.

Driving InstructionsPower Assistance

Warning!

When the engine is not running, thebrake and steering systems arewithout power assistance. Underthese circumstances, a much greatereffort is necessary to stop or steer thevehicle.

Brakes

Caution!

When driving down long and steepgrades, relieve the load on the brakesby shifting into "3", "2" or "B" (formodels SL 500 and SL 600). This helpsprevent overheating of the brakes andreduces brake pad wear. Do not exceedengine speed limits. Refer to TechnicalData for downshift points.

After hard braking, it is advisable todrive on for some time, rather thanimmediately parking, so the air streamwill cool down the brakes faster..

Warning!

After driving in heavy rain for sometime without applying the brakes orthrough water deep enough to wetbrake components, the first brakingaction may be somewhat reducedand increased pedal pressure maybe necessary. Be sure to maintain asafe distance from vehicles in front.

The condition of the parking brakesystem is checked each time the car isin the shop for the requiredmaintenance.Between maintenance checks, it is agood practice to apply the parkingbrake once or twice while driving atapproximately 30 mph (50 km/h) on adry straight road. Apply parking brakelightly while pulling the release handleout until a slight drag on the wheels isfelt. Keep applying the brake for about10 seconds while pulling the releasehandle out before releasing the parkingbrake completely. This practice willkeep the parking brake at maximumefficiency.

Warning!

The stop lamps will not come onwhen applying the parking brakeonly. Perform the procedure in theprevious paragraph only when theroad is clear of other traffic.

Resting your foot on the brake pedalwill cause excessive and prematurewear of the brake pads.It can also result in the brakesoverheating thereby significantlyreducing their effectiveness. It maynot be possible to stop the car insufficient time to avoid an accident.

All checks and maintenance work onthe brake system should be carried outby an authorized Mercedes-Benzdealer.

17

If the parking brake is released and thebrake warning lamp in the instrumentcluster stays on, the brake fluid level inthe reservoir is too low.

Brake pad wear or a leak in the systemmay be the reason for low brake fluidin the reservoir.

Have the brake system inspected at anauthorized Mercedes-Benz dealerimmediately.

Install only brake pads and brake fluidrecommended by Mercedes-Benz.

Warning!

If other than recommended brakepads are installed, the brakingproperties of the vehicle can beaffected to an extent that safebraking is substantially impaired.

Tires

Tread wear indicators (TWI) arerequired by law. These indicators arelocated in six places on the treadcircumference and become visible at adepth of approximately 1/16 in (2 mm),at which point the tire is consideredworn and should be replaced.The tread wear indicator appears as asolid band across the tread.

Warning!

Do not allow your tires to weardown too far. With less than 1/16 in(1.5 mm) of tread, the adhesionproperties on a wet road are sharplyreduced.Depending upon the weather and/orroad surface (conditions), the tiretraction varies widely.

Specified tire pressures must bemaintained. This applies particularly ifthe tires are subjected to high loads(e.g. high speeds, heavy loads, highambient temperatures).

Warning!

Do not drive with a flat tire. A flattire affects the ability to steer orbrake the vehicle. You may losecontrol of the car. Continueddriving with a flat tire or driving athigh speed with a flat tire will causeexcessive heat build-up and possiblya fire.

18

Aquaplaning

Depending on the depth of the waterlayer on the road, aquaplaning mayoccur, even at low speeds and with newtires. Avoid track grooves in the roadand apply brakes cautiously in the rain.

Tire Traction

The safe speed on a wet, snow coveredor icy road is always lower than on adry road.You should pay particular attention tothe condition of the road as soon as theprevailing temperatures fall close to thefreezing point.

Warning!

If ice has formed on the road, tiretraction will be substantiallyreduced. Under such weatherconditions, drive, steer and brakewith extreme caution.

We recommend M + S radial-ply tiresfor the winter season for all fourwheels to insure normal balancedhandling characteristics.

On packed snow, they can reduce yourstopping distance as compared withsummer tires. Stopping distance,however, is still considerably greaterthan when the road is wet or dry.

Parking

Warning!

To reduce the risk of personal injuryas a result of vehicle movement,before turning off the engine andleaving the vehicle always:

1. Keep foot on brake pedal.2. Firmly depress parking

brake pedal.3. Engage first or reverse

gear (selector lever position “P”in the case of automatictransmissions).

4. Slowly release brake pedal.5. Turn front wheels towards

the road curb.6. Turn the key to steering

lock position 0 and remove.

Important!

It is advisable to set the parking brakewhenever parking or leaving thevehicle. In addition, engage first orreverse gear (selector lever position“P”).When parking on hills, always set theparking brake.

19

Winter Driving Instructions

The most important rule for slippery oricy roads is to drive sensibly and toavoid abrupt acceleration, braking andsteering action. Do not use the cruisecontrol system under such conditions.

When the vehicle is in danger ofskidding, declutch, or in case ofautomatic transmission move selectorlever to position “N”. Try to keep thevehicle under control by correctivesteering action.Road salts and chemicals can adverselyaffect braking efficiency. Increasedpedal force may become necessary toproduce the normal brake effect. Wetherefore recommend depressing thebrake pedal periodically when travelingat length on salt-strewn roads. This canbring road salt impaired brakingefficiency back to normal. Aprerequisite is, however, that this isdone without endangering other driverson the road.

If the vehicle is parked after beingdriven on salt treated roads, the brakingefficiency should be tested as soon aspossible after driving is resumed whileobserving the safety rules in theprevious paragraph.

Warning!

If the vehicle becomes stuck in snow,make sure that snow is kept clear ofthe exhaust pipe and from aroundthe vehicle with engine running.Otherwise, deadly carbon monoxide(CO) gases may enter vehicle interiorresulting in unconsciousness anddeath.To assure sufficient fresh airventilation, open a window slightlyon the side of the car that is out ofthe wind.

Passenger Compartment

Warning!

Always fasten items being carried assecurely as possible.In an accident, during hard brakingor sudden maneuvers, loose itemswill be thrown around inside thevehicle, and cause injury to vehicleoccupants unless the items aresecurely fastened in the vehicle.

Seat Belts and SupplementalRestraint System (SRS)

Your vehicle is equipped with lap-shoulder seat belts, emergencytensioning retractors for the seat belts,driver airbag and knee bolster andpassenger airbag and knee bolster.

Seat Belts

Important!

Laws in most states and all Canadianprovinces require seat belt use.

All states and provinces require use ofchild restraints that comply with U.S.Federal Motor Vehicle Safety Standard213 and Canadian Motor VehicleSafety Standard 213.1. We stronglyrecommend their use.

Seat Belt Warning System

With the key in steering lockposition 2, an audible warning soundsfor a short time if the driver's seat beltis not fastened.

Warning!

Failure to wear and properly fastenand position your seat belt greatlyincreases your risk of injuries andtheir likely severity in an accident.You and your passengers shouldalways wear seat belts.If you are ever in an accident, yourinjuries can be considerably moresevere without your seat beltproperly buckled. Without your seatbelt buckled, you can hit the interiorof the vehicle or be ejected from it.You can be seriously injured orkilled.

In the same crash, the possibility forinjury or death is lessened with yourseat belt buckled.

The seat belts provide protectiononly with the backrest locked inplace. If the seat belt warning lampdoes not go out, but is instead lit con-tinuously, then a backrest is notengaged in its lock.

Never ride in a moving vehicle withthe seat back reclined. Sitting in anexcessively reclined position can bedangerous. You could slide under theseat belt in a collision. If you slideunder it, the belt would apply forceat the abdomen or neck. That couldcause serious or even fatal injuries.The seat back and seat belts providethe best restraint when the wearer isin an upright position and belts areproperly positioned on the body.

Fastening of Seat Belts

Pull belt with latch plate (1) acrossshoulder and lap. Push latch plate (1)into buckle (2) until it clicks. The lapbelt should be positioned as low aspossible on your hips and not acrossthe abdomen. Do not twist the belt. Atwisted seat belt may cause injury.For safety reasons, avoid adjusting theseat or seat back into positions whichcould affect the correct seat beltposition.

Press switch (4) to adjust seat belt sothat the shoulder portion is located asclose as possible to the middle of yourshoulder.The shoulder portion of the seat beltmust be pulled snug and checked forsnugness immediately after engaging itand during driving. Tighten the lapportion to a snug fit by pullingshoulder portion up.

41

Unfastening of Seat Belts

Push in the red button (3) in the beltbuckle (2).

Allow the retractor to completelyrewind the seat belt by guiding thelatch plate (1).

Operation:

The inertia reel stops the belt fromunwinding during sudden vehicle stopsor when quickly pulling on the belt.

The locking function of the reel may bechecked by quickly pulling on the belt.

The emergency tensioning retract orstighten the fastened seat belts duringfrontal and front-angled impactsexceeding the first threshold of theSRS (see Index).

Note:For cleaning and care of the seat belts,see Cleaning and Care of the Vehiclein Index.

42

Warning!

USE SEAT BELTS PROPERLY.

• Each occupant should weartheir seat belt at all times.Together with the "SRS", theseat belt offers the bestconditions for protection of thebody in case of major frontalimpact.

• Improperly positioned seatbelts do not provide maximum protection and maycause serious injuries incase of an accident.

• Never wear the shoulderbelt under your arm, againstyour neck or off your shoulder.In a crash, your body wouldmove too far forward. Thatwould increase the chance ofhead and neck injuries. The beltwould also apply top much forceto the ribs, which could severelyinjure internal organs such asyour liver or spleen.

• Position the lap belt as lowas possible on your hipsand not across theabdomen. If the belt ispositioned across yourabdomen, it could causeserious injuries in a crash.

• Each seat belt should neverbe used for more than oneperson at a time. Do notfasten a seat belt around aperson and objects.

• Belts should not be worntwisted. In a crash, youwouldn't have the full widthof the belt to take impactforces. The twisted beltagainst your body couldcause injuries.

• Pregnant women shouldalso use a lap-shoulder belt.The lap belt portion shouldbe positioned as low aspossible on the hips toavoid any possible pressureon the abdomen.

USE CHILD RESTRAINTSPROPERLY.

• Infants and small childrenmust be seated in an infantor child restraint system,which is properly securedby a lap belt or lap beltportion of a lap-shoulderbelt. Children could beendangered in an accident iftheir child restraints are notproperly secured in thevehicle.

• Rear-facing child restraintsmust not be used in thefront seat. They could bestruck by the airbag when itinflates in a crash. If thishappens, a child in therestraint could be seriouslyinjured.

• Children too big for childrestraint systems shoulduse regular seat belts.Position shoulder beltacross chest and shoulder,not face or neck. A boosterseat may be necessary toachieve proper beltpositioning.

43

Supplemental Restraint System(SRS)

The SRS uses two crash severity levels(thresholds) to activate either the ETRor airbag or both. Activation dependson the direction and severity of theimpact, exceeding the thresholds andfastening of the seat belt.

Seat belt fastened

• first threshold exceeded:ETR activates

• second threshold exceeded:airbag also activates

Seat belt not fastened

• first threshold exceeded:airbag activates, but not ETR

Driver and front passenger systemsoperate independently from each other.

Emergency TensioningRetractor (ETR)

The seat belts are equipped withemergency tensioning retractors. Thesetensioning retractors are located in eachbelt's inertia reel and becomeoperationally ready with the key insteering lock position 1 or 2.

The emergency tensioning retractorsare designed to activate only when theseat belts are fastened during frontaland front-angled impacts exceeding thefirst threshold of the SRS. They re-move slack from the belts in such away that the seat belts fit more snuglyagainst the body, restricting its forwardmovement as much as possible.

In cases of other frontal impacts, roll-overs, certain side impacts, rearcollisions, or other accidents withoutfrontal forces, the emergencytensioning retractors will not beactivated. The driver and passengerwill then be protected by the fastenedseat belts and inertia reel in the usualmanner.

For seat belt and emergency tensioningretractor safety guidelines, see SafetyGuidelines in Index.

44

Airbags

The most effective occupant restraintsystem yet developed for use inproduction vehicles is the seat belt. Insome cases, however, the protectiveeffect of a seat belt can be furtherenhanced by an airbag.

The driver airbag (1) is located in thesteering wheel hub. The passengerairbag (2) is located in the dashboardahead of the passenger. In conjunctionwith wearing the seat belts withemergency tensioning retractors (4),they provide increased protection forthe driver and passenger.The operational readiness of theairbag system is verified by theindicator lamp "SRS" (3) in theinstrument cluster. If no fault isdetected, the lamp will go out afterapproximately 4 seconds; after thelamp goes out, the system continuesto monitor the components andcircuitry of the airbag system andwill indicate a malfunction bycoming on again.

45

The following system components aremonitored or undergo a self-check:crash-sensor, airbag ignition circuits,driver and passenger seat belt buckles.Initially, when the key is turned fromsteering lock position 0 to positions 1or 2, malfunctions in the crash-sensorare detected and indicated (the "SRS"indicator lamp stays on longer than 4seconds).

In the operational mode, after theindicator lamp has gone out followingthe initial check, interruptions andshort circuits in the airbag ignitioncircuit and in the driver and passengerseat belt buckle harnesses, and lowvoltage in the entire system aredetected and indicated.

In the event a malfunction of the"SRS" is indicated as outlined above,the "SRS" may not be operational. Westrongly recommend that you visit anauthorized Mercedes-Benz dealerimmediately to have the systemchecked; otherwise the "SRS" may notbe activated when needed.

Important!

The airbags are designed to activateonly in certain frontal and front-angled impacts. Only during thesetypes of impacts will they providetheir supplemental protection. Thedriver and passenger should alwayswear the seat belts, otherwise it is notpossible for the airbags to providetheir intended supplementalprotection.In cases of other frontal impacts,roll-overs, certain side impacts, rearcollisions, or other accidents withoutfrontal forces, the airbags will not beactivated. The driver and passengerwill then be protected by thefastened seat belts.

We caution you not to rely on thepresence of an airbag in order toavoid wearing your seat belt.

Important!

The "SRS" is designed to reduce thepotential of injury in certain frontaland front-angled impacts which maycause injuries, however, no systemavailable today can totally eliminateinjuries and fatalities.

The activation of the "SRS"temporarily releases a small amountof dust from the air-bags. This dust,however, is neither injurious to yourhealth, nor does it indicate a fire inthe vehicle.

The service life of the airbagsextends to the date indicated on thelabel located on the driver-side doorlatch post. To provide continuedreliability after that date, theyshould be inspected by an authorizedMercedes-Benz dealer at that timeand replaced when necessary.

46

Warning!

It is very important for your safety toalways be in a properly seatedposition and to wear your seat belt.For maximum protection in the eventof a collision always be in normalseated position with your backagainst the seat back. Fasten yourseat belt and ensure that it isproperly positioned on the body.

Since the airbag inflates withconsiderable speed and force, aproper seating position willkeep you in a safe distance from theairbag:

• Sit properly belted in anupright position with your backagainst the seat back.

• Do not lean with your head orchest close to the steering wheelor dashboard.

• Adjust the driver seat as faras possible rearward, stillpermitting proper operationof vehicle controls.

• Adjust the passenger seatas far as possible rearward fromthe dashboard, especially when achild restraint is installed.

• Infants and small childrenshould only be seated in aninfant or child restraintwhich is properly securedby the seat belt.

• Rear-facing child restraintsmust not be used in a front seat.

Failure to follow these instructionscan result in severe injuries to you orother occupants.

47

Safety Guidelines for the Seat Belt,Emergency Tensioning Retractorand Airbag

Warning!

• Damaged belts or belts that werehighly stressed in an accidentmust be replaced and theiranchoring points must also bechecked. Use only belts installedor supplied by an authorizedMercedes-Benz dealer.

• Do not pass belts over sharpedges.

• Do not make any modificationthat could change theeffectiveness of the belts.

• The "SRS" is designed tofunction on a one-time-onlybasis. An airbag or emergencytensioning retractor (ETR) thatwas activated must be replaced.

• No modifications of any kindmay be made to any componentsor wiring of the "SRS". Thisincludes the installation ofadditional trim material, badgesetc. over the steering wheel hubor front passenger airbag coverand installation of additionalelectrical/electronic equipmenton or near "SRS" componentsand wiring.

• Several airbag system com-ponents at the steering wheel gethot after the air-bag has inflated.Don't try to touch them.

• Improper work on the system,including incorrect installationand removal, can lead to possibleinjury through an uncontrolledactivation of the "SRS".

• In addition, through improperwork there is the risk ofrendering the "SRS"inoperative. Work on the "SRS"must therefore only beperformed by an authorizedMercedes-Benz dealer.

• When scrapping the airbag unitor emergency tensioningretractor, it is mandatory tofollow our safety instructions.These instructions are availableat your authorized Mercedes-Benz dealer.

When you sell the vehicle we stronglyurge you to give notice to thesubsequent owner that it is equippedwith an "SRS" by alerting him to theapplicable section in the Owner'sManual.

Infants and Child RestraintSystems

We recommend that all infants andchildren be restrained at all times whilethe vehicle is in motion.

Important!

The use of infant or child restraints isrequired by law in all 50 states and allCanadian provinces.Infants and small children should beseated in an infant or child restraintsystem, which is properly secured bythe lap belt portion of the lap-shoulderbelt, and that complies with U.S.Federal Motor Safety Standard 213 andCanadian Motor Vehicle SafetyStandard 213.1.A statement by the child restraintmanufacturer of compliance with thisstandard can be found on theinstruction label on the restraint and inthe instruction manual provided withthe restraint.When using any infant or childrestraint system, be sure to carefullyread and follow all manufacturer'sinstructions for installation and use.

Warning!

Rear-facing child restraints must notbe used in a front seat They could bestruck by the airbag when it inflatesin a crash. If this happens, a child inthe restraint could be seriouslyinjured.

Infants and small children shouldnever be held on the lap while thevehicle is in motion. During anaccident they would be almostimpossible to hold, and could becrushed between the adult and thedashboard.

Infants and small children shouldnever share a seat belt with anotheroccupant. During an accident, theycould be crushed between theoccupant and seat belt.

Children too big for child restraintsystems should use regular seatsbelts. Position the shoulder beltacross the chest and shoulder, notthe face or neck. A booster seat maybe necessary to achieve proper beltpositioning.

When the child restraint is not in use,remove it from the car or secure itwith the seat belt to prevent the childrestraint from becoming a projectilein the event of an accident.

U.S.A. Models only

Since 1986 all U.S. child restraintscomply with U.S. regulations withoutthe use of a tether strap.

Drinking and Driving

Warning!

Drinking and driving can be a verydangerous combination. Even a smallamount of alcohol or drugs can affectyour reflexes, perceptions andjudgment. The possibility of a seriousor even fatal accident is sharplyincreased when you drink and drive.Please don't drink and drive or allowa friend to drive when he has beendrinking.

Engine Oil Pressure Gauge

The oil pressure at idle speed may dropif the engine is at operatingtemperature. This will not jeopardizethe engine's operational reliability.Pressure must, however, riseimmediately upon acceleration.Note:If the oil pressure gauge needle dropsto "0" with the engine running, thendamage to the engine may occur withcontinued operation. Turn off engineimmediately and contact an authorizedMercedes-Benz dealer. Do not operatethe car until the condition is repaired.

Parking Brake

To engage, depress parking brakepedal. With the key in steering lockposition 2, the brake warning lamp inthe instrument cluster should come onbrightly (function check for lamp).To release the parking brake, pullhandle on instrument panel. The brakewarning lamp in the instrument clustershould go out (also see brake warninglamp, page 88).

Driving Off

Test the brakes briefly after drivingoff. Perform this procedure only whenthe road is clear of other traffic.Warm up the engine smoothly. Do notplace full load on the engine until theoperating temperature has beenreached.

Tachometer

Red marking on tachometer:Excessive engine speed.Avoid this engine speed, as it mayresult in engine damage that is notcovered by the Mercedes-Benz LimitedWarranty.For engine protection, the fuel supplyis interrupted if the engine is operatedwithin the red marking.

Warning!

Keep driver's foot area clear at alltimes. Objects stored in this areamay impair pedal movement.

74

Automatic Transmission

The automatic transmission selectsindividual gears automatically,dependent upon

• Selector lever position• Accelerator position• Vehicle speed

Important!

When parking the car and beforeworking on the vehicle with the enginerunning, firmly depress the parkingbrake pedal and shift the selector leverinto "P".

Driving

The selector lever is automaticallylocked while in position "P". To movethe selector lever out of position "P",the service brake pedal must be firmlydepressed before the shift lock willrelease.

Shift selector lever to the desiredposition only when the engine is idlingnormally and the service brake isapplied. Do not release the brake untilready to drive. The vehicle mayotherwise start creeping when theselector lever is in drive or reverseposition.

Warning!

It is dangerous to shift the selectorlever out of "P" or "N" if the enginespeed is higher than idle speed. Ifyour foot is not on the brake pedal,the car could accelerate quicklyforward or in reverse. You could losecontrol of the car and hit someone orsomething. Only shift into gear whenthe engine is idling normally andwhen your right foot is firmly on thebrake pedal.

Important!After selecting any driving positionfrom "N" or "P", wait a moment toallow the gear to fully engage beforeaccelerating, especially when theengine is cold.

Accelerator position

Partial throttle = early upshifting =normal acceleration

Full throttle = later upshifting = rapidacceleration

Kickdown (depressing the acceleratorbeyond full throttle) = downshifting tonext lowest gear = maximumacceleration. Once the desired speed isattained, ease up on the accelerator -the transmission shifts up again.

75

Selector Lever Positions SL 320

The automatic gear shifting process canbe adapted to specific operatingconditions using the selector lever.

P Parking lock.The parking lock is an additionalsafeguard to the parking brake whenparking the vehicle. Engage onlywith the car stopped.

Note:The key can be removed from thesteering lock only with the selectorlever in position "P". With the keyremoved, the selector lever islocked in position "P".

R Reverse gear.Shift to reverse gear only with thecar stopped.

N Neutral.No power is transmitted from theengine to the rear axle. When thebrakes are released, the vehicle canbe moved freely (pushed or towed).Do not engage "N" while drivingexcept to coast when the vehicle isin danger of skidding (e.g. on icyroads, see page 19).

Important!

Coasting the vehicle for an extendedperiod of time with selector lever in"N" can result in transmission damage.That is not covered by theMERCEDES-BENZ LimitedWarranty.

D The transmission automaticallyupshifts to 5th gear. Position "D"provides optimum drivingcharacteristics under all normaloperating conditions.

3 Upshift to 4th gear only.Suitable for performance driving.

4 Upshift to 3rd gear only. Suitablefor moderately steep hills. Since thetransmission does not shift higherthan 3rd gear, this gear selectionwill allow use of the engine'sbraking power downhill.

2 Upshift to 2nd gear only.For driving in mountainous regionsor under extreme operatingconditions. This gear selection willallow use of the engine's brakingpower when descending steepgrades.

Important!

With selector lever in position "D", "4"or "3", upshifting from 1st to 2nd to3rd gear is delayed depending onvehicle speed and engine temperature.This allows the catalytic converter toheat up more quickly to operatingtemperatures.During the brief warm-up period thisdelayed upshift and increased enginenoise might be perceived as amalfunction. However, neither theengine nor transmission are negativelyaffected by this mode of operation.

76

Important!

The delayed upshift is effective withvehicle speeds below 31 mph (50km/h) at partial throttle and enginetemperatures below 95°F (35°C).

Do not exceed the vehicle speed limitsfor individual gear selections, whichare indicated by marks (I, II, III, etc.)on the circumference of thespeedometer.To avoid over-revving the engine, theselector lever cannot be moved to alower gear if the vehicle speed exceedsthe speed limit of that gear.

Warning!

On slippery road surfaces, neverdownshift in order to obtain brakingaction. This could result in rearwheel slip and reduced vehiclecontrol. Your vehicle's ABS will notprevent this type of loss of control.

To prevent the engine from laboring atlow RPMs, do not allow the enginespeed to drop too low on uphillgradients.

Depending on the degree of the incline,shift selector lever to a lower gear earlyenough to maintain engine RPM withinthe best torque range.

Stopping

For brief stops, e.g. at traffic lights,leave the transmission in gear and holdvehicle with the service brake.For longer stops with the engine idling,shift into "N" or "P".When stopping the car on an uphillincline, do not hold it with theaccelerator, use the brake. This avoidsunnecessary transmission heat build up.

Maneuvering

To maneuver in tight areas, e.g. whenpulling into parking space, control thecar speed by gradually releasing thebrakes. Accelerate gently and neverabruptly step on the accelerator.To rock a car out of soft ground (mudor snow), alternately shift fromforward to reverse, while applyingslight partial throttle.Rocking a car free in this manner maycause the ABS warning lamp to comeon. Turn off and restart the engine toclear the malfunction indication.

Warning!

Getting out of your car with theselector lever not fully engaged inposition "P" is dangerous. Whenparked on a steep incline, position"P" alone may not prevent yourvehicle from rolling, possibly hittingpeople or objects.Always set the parking brake inaddition to shifting to position "P".When parked on an incline, also turnfront wheel against curb.

Important!

Coasting the vehicle for an ex-tended period of time with selectorlever in "N" can result intransmission damage. That is notcovered by the MERCEDES-BENZ Limited Warranty.

D The transmission automaticallyupshifts to 4th gear. Position "D"provides optimum drivingcharacteristics under all normaloperating conditions.

3 Upshift to 3rd gear only. Suitablefor moderately steep hills.

2 Upshift to 2nd gear only. Fordriving in mountainous regions.Since the transmission does notshift higher than 2nd gear, thisgear selection will allow use ofthe engine's braking powerdownhill.

B In this position, the engine'sbraking effect is utilized byshifting into 1st gear. Use thisposition while descending verysteep or lengthy downgrades andonly at speeds below 40 mph (60km/h).

Important!

With selector lever in position "D" or"3", upshifting from 2nd to 3rd gear isdelayed depending on vehicle speedand engine temperature. This allowsthe catalytic converter to heat up morequickly to operating temperatures.During the brief warm-up period thisdelayed upshift and increased enginenoise might be perceived asmalfunction. However, neither theengine nor transmission are negativelyaffected by this mode of operation.

78

The delayed upshift is effective withvehicle speeds below 31 mph (50km/h) at partial throttle and enginetemperatures below 95°F(35°C).

Important!

Do not exceed the vehicle speed limitsfor individual gear selections, whichare indicated by marks (I, II, III etc.) onthe circumference of the speedometer.Do not brake the vehicle bydownshifting to a lower gear (forexample from "D" to "3") unless thespeedometer needle is below the speedlimit mark of that particular gear range.Overrewing could result in seriousdamage to the engine.

Warning!

On slippery road surfaces, neverdownshift in order to obtain brakingaction. This could result in rearwheel slip and reduced vehiclecontrol Your vehicle's ABS will notprevent this type of loss of control.This applies particularly forposition "B".

To prevent the engine from laboring atlow RPMs, do not allow the enginespeed to drop too low on uphillgradients.Depending on the degree of the incline,shift selector lever to a lower gearrange early enough to maintain engineRPM within the best torque range.

Maneuvering

To maneuver in tight areas, e.g. whenpulling into parking space, control thecar speed by gradually releasing thebrakes. Accelerate gently and neverabruptly step on the accelerator.

To rock a car out of soft ground (mudor snow), alternately shift fromforward to reverse, while applyingslight partial throttle.

Rocking a car free in this manner maycause the ABS warning lamp to comeon. Turn off and restart the engine toclear the malfunction indication.

Stopping

For brief stops, e.g. at traffic lights,leave the transmission in gear and holdvehicle with the service brake.

For longer stops with the engine idling,shift into "N" or "P".

When stopping the car on an uphillincline, do not hold it with theaccelerator, use the brake. This avoidsunnecessary transmission heat build up.

Warning!

Getting out of your car with theselector lever not fully engaged inposition "P" is dangerous. Whenparked on a steep incline, position"P" alone may not prevent yourvehicle from moving, possibly hittingpeople or objects.Always set the parking brake inaddition to shifting to position "P".When parked on an incline,also turn front wheel against curb.

79

Cruise ControlAny given speed above approximately25 mph (40 km/h) can be maintainedwith the cruise control by operating thelever.

1. Accelerate and set:Lift lever briefly to set speed. Holdlever up to accelerate.

2. Decelerate and set:Depress lever briefly to setspeed.Hold lever down to decelerate.

Normally the vehicle is accelerated tothe desired speed with the accelerator.

Speed is set by briefly pushing thelever to position 1 or 2. The acceleratorcan be released.

The speed can be increased (e.g. forpassing) by using the accelerator. As"soon as the accelerator is released, thepreviously set speed will be resumedautomatically.If a set speed is to be increased ordecreased slightly, e.g. to adapt to thetraffic flow, hold lever in position 1 or2 until the desired speed is reached, orbriefly tip the control lever in theappropriate direction for increases ordecreases in 1 km/h (0.6 mph)increments. When the lever is released,the newly set speed remains.

3. CancelingTo cancel the cruise control,briefly push lever to position 3.When you step on the brake orclutch pedal or the vehicle speeddrops below approx. 40 km/h (25mph), for example when drivingupgrade, the cruise control will becanceled.If the cruise control cancels byitself and remains inoperative untilthe engine is restarted, have thesystem checked at your authorizedMERCEDES-BENZ dealer as soonas possible.

4. ResumeIf the lever is briefly pushed toposition 4 when driving at a speedexceeding approx. 40 km/h (25mph), the vehicle resumes thespeed which was set prior to thecancellation of the cruise control.The last memorized speed iscanceled when the key in thesteering lock is turned to position 1or 0.

80

Note:If the engine does not brake the vehiclesufficiently while driving on adowngrade, the speed you set on thecruise control may be exceeded andyou may have to step on the brakepedal to slow down. As soon as thegrade eases, the cruise controlled speedwill again be maintained as long as thebrakes were not previously applied, orthe lever may be used to resume thepreviously set speed if the brakes wereapplied.

Warning!

Only use the cruise control if thetraffic and weather conditions makeit advisable to travel at a steadyspeed.

• The use of cruise controlcan be dangerous on windingroads or in heavy trafficbecause conditions do notallow safe driving at asteady speed.

• The use of cruise controlcan be dangerous on slipperyroads. Rapid changesin tire adhesion can resultin wheel spin and loss ofcontrol.

The "Resume" function should onlybe operated if the driver is fullyaware of the previously set speed andwishes to resume this particularpreset speed.

Caution!

When driving with the cruise controlengaged, the transmission selectorlever must not be shifted to position"N" as otherwise the engine willoverrev, possibly causing enginedamage that is not covered by theMercedes-Benz Limited Warranty.

81

Charge Indicator Lamp

Should the charge indicator lamp fail tocome on prior to starting when the keyis in steering lock position 2 or shouldit fail to go out after starting or duringoperation, this indicates a fault whichmust be repaired at an authorizedMERCEDES-BENZ dealerimmediately.

If the charge indicator lamp comes onwhile the engine is running, this mayindicate that the poly-V-belt hasbroken. Should this condition occur,the poly-V-belt must be replaced beforecontinuing to operate the vehicle.Otherwise, the engine will overheat dueto an inoperative water pump whichmay result in damage to the engine.

Do not continue to drive the vehiclewith the charge indicator lampilluminated. Doing so could result inengine damage that is not covered bythe Mercedes-Benz Limited Warranty.

Engine Oil Pressure Gauge withOil Pressure Warning Lamp

With the key in steering lock position2, the oil pressure warning lamp comeson and goes out with the enginerunning.The oil pressure at idle speed may dropif the engine is at operatingtemperature. This will not jeopardizethe engine's operational reliability.

Pressure must, however, riseimmediately upon acceleration.

Note:If the oil pressure warning lamp doesnot go out after starting the engine orcomes on while driving and the oilpressure gauge needle drops to "0",then damage to the engine may occurwith continued operation. Turn offengine immediately and contact anauthorized MERCEDES-BENZ dealer.Do not operate the car until thecondition is repaired.

There is no need for concern should theoil pressure warning lamp light upbriefly, (for example, in sharp turns orhard braking) provided the lamp goesout immediately. We recommend youto drive to the nearest service stationwhere the engine oil should be toppedto the "full" mark on the dipstick withan approved oil.

82

Low Engine Oil Level WarningLamp

With the key in steering lock position2, the oil pressure warning lamp comeson and goes out with the enginerunning.If the warning lamp comes on with theengine running and at operatingtemperature, the engine oil level hasdropped to approximately the minimummark on the dipstick.

When this occurs, the warning lampwill first come on intermittently andthen stay on if the oil level dropsfurther.

If no oil leaks are noted and there isindicated engine oil pressure, continueto drive to the nearest service stationwhere the engine oil should be toppedto the "full" mark on the dipstick withan approved oil.

The low engine oil level warning lightshould not be ignored. Extendeddriving with the light illuminated couldresult in engine damage that is notcovered by the Mercedes-Benz LimitedWarranty.

In addition to the warning lamp, theengine oil level should be periodicallychecked with the dipstick, for exampleduring a fuel stop, or before a long trip.See page 98.

Engine Oil Consumption

Engine oil consumption checks shouldonly be made after the break-in period.During the break-in period, higher oilconsumption may be noticed and isnormal. Frequent driving at highengine speeds results in increasedconsumption.

Fuel Consumption Gauge

While driving, instantaneous fuelconsumption is indicated in miles pergallon (mpg), or in Canada liters per100 kilometers (I/100 km).

With the engine switched off, theneedle reads "0".

Due to system design, maximumconsumption is indicated at idle speed.

83

Fuel Reserve Warning Lamp

With the key in steering lock position2, the fuel reserve warning lamp comeson and goes out with the enginerunning.If the warning lamp does not go outafter starting the engine or if it comeson while driving, it indicates that thefuel level is down to the reservequantity of approx. 2.6 gal (10 liters).

Outside Temperature Indicator

The temperature sensor is located inthe front bumper area. Due to itslocation, the sensor can be affected byroad or engine heat during idling orslow driving. This means that theaccuracy of the displayed temperaturecan only be verified by comparison to athermometer placed next to the sensor,not by comparison to external displays(e.g. bank signs, etc.).Adaptation to ambient temperaturetakes place in steps and depends on theprevailing driving conditions (stop-and-go or moderate, constant driving)and amount of temperature change.

Warning!

The outside temperature indicator isnot designed to serve as an Ice-Warning Device and is therefore un-suitable for that purpose. Indicatedtemperatures just above the freezingpoint do not guarantee that the roadsurface is free of ice.

Coolant Temperature Gauge

If the antifreeze mixture is effective to-22°F (-30°C ), the boiling point of thecoolant in the pressurized coolingsystem of your vehicle is approx.266°F (130°C).During severe operating conditions andstop-and-go city traffic, the coolanttemperature may rise close to the redmarking.The engine should not be operated withthe coolant temperature in the red zone.Doing so may cause serious enginedamage which is not covered by theMercedes-Benz Limited Warranty.

Warning!

• Driving when your engine isbadly overheated can cause somefluids which may have leaked intothe engine compartment to catchfire. You could be seriouslyburned. Turn off the engine andget out of the car until it coolsdown.

• Steam from an overheated enginecan cause serious burns and canoccur just by opening the enginehood. Stay away from the engineif you see or hear steam comingfrom it. Turn off the engine anddo not stand near the car until itcools down.

With the key in steering lock position2, the warning lamp comes on and goesout with the engine running.

Warning!

If the warning lamp does not go outafter starting the engine, or if itcomes on while driving, and theindicator lamps in the roll bar switchblink simultaneously, then the rollbar system is defective and may notactivate in an accident. In this case,raise the roll bar manually (seeIndex) before continuing to drive.

Have the roll bar system checked atyour authorized MERCEDES-BENZdealer as soon as possible.

Seat Belt and Backrest LockWarning Lamp

With the key in steering lock position2, the warning lamp comes on and anaudible warning sounds for a shorttime if the driver's seat belt is notfastened.

If a backrest is not engaged in its lock,an audible warning will soundintermittently for up to approx. 20seconds.

After starting the engine, the warninglamp blinks for a brief period toremind the driver and passenger tofasten seat belts before driving off.

If the warning lamp does not go putafter blinking briefly, but is instead litcontinuously, then a backrest is notengaged in its lock.

The warning lamp goes out as soon asthe backrest is engaged in its lock.

If the backrest is locked and thewarning lamp does not go out, havethe system checked at your authorizedMERCEDES-BENZ dealer as soon aspossible.

Exterior Lamp Failure IndicatorLamp

With the key in steering lock position2, a dim indicator lamp comes on andgoes out with the engine running.

With the key in steering lock position 2or with the engine running, a brightillumination of this lamp indicates anexterior lamp failure (except highmounted stop lamp).

Note:The indicator lamp will also come on ifan incorrect bulb is installed.If additional lighting equipment isinstalled (e.g. auxiliary headlampsetc.) be certain to connect into thefuse before the failure indicatormonitoring unit in order to avoiddamaging the system.

If an exterior lamp fails, the in-dicator lamp will come on onlywhen that lamp is switched on.

If a brake or turn signal lamp fails, thelamp failure indicator will come onwhen applying the brake or actuatingthe turn signal and stay on until theengine is turned off.

86

Brake Pad Wear Indicator Lamp

The brake pad wear indicator lamp inthe instrument cluster comes on whenthe key in the steering lock is turned toposition 2 and goes out when theengine is running.

If the indicator lamp lights up duringbraking, this indicates that the frontwheel brake pads are worn down(vehicles equipped with ASR frontand/or rear wheel brake pads).

Have the brake system checked at yourauthorized MERCEDES-BENZ dealeras soon as possible.•

Brake Warning Lamp

The brake warning lamp will come on:

• when there is insufficient brakefluid in the reservoir (enginerunning and parking brake released)

• as a lamp function check (key insteering lock position 2).

When the minimum mark on thereservoir is reached, have the brakesystem checked for brake pad thicknessand leaks.

To test the brake warning lamp, turnthe key in steering lock to position 2.The brake warning lamp comes on, andshould go out when the engine isrunning.

Warning!

Driving with the brake warninglamp on can result in an accident.Have your brake system checkedimmediately if the brake warninglamp stays on. Don't add brake fluidbefore checking the brake system.Overfilling the brake fluid reservoircan result in spilling brake fluid onhot engine parts and the brake fluidcatching fire. You can be seriouslyburned.

87

Antilock Brake System (ABS)

The ABS prevents the wheels fromlocking up above a vehicle speed ofapproximately 3 km/h (2 mph)independent of road surface conditions.It is necessary, however, that thevehicle speed reaches at least 8 km/h (5mph) before commencing to brake.

At the instant one of the wheels isabout to lock up, a slight pulsation canbe felt in the brake pedal, indicatingthat the ABS is in the regulating mode.

On slippery road surfaces, the ABSwill respond even with only slightbrake pedal pressure. The pulsatingbrake pedal can be an indication ofhazardous road conditions andfunctions as a reminder to take extracare while driving.

The ABS warning lamp in theinstrument cluster comes on with thekey in steering lock position 2 andshould go out with the engine running.

If the charging voltage falls below 10volts, the warning lamp comes on andthe ABS is switched off. When thevoltage is above this value again, thewarning lamp should go out and theABS will be operational.

If the ABS warning lamp does not goout or comes on while driving, itindicates that the ABS has detected amalfunction and has switched off. Inthis case, the brake system functions inthe usual manner, but without antilockassistance.

Have the system checked at yourauthorized MERCEDES-BENZ dealeras soon as possible.

Warning!

Even the ABS cannot prevent thenatural laws of physics from actingon the vehicle. The ABS cannotprevent accidents, including thoseresulting from excessive speed inturns, following another vehicle tooclosely, or aquaplaning. Only a safe,attentive, and skillful driver canprevent accidents. The capabilities ofan ABS equipped car must never beexploited in a reckless or dangerousmanner which could jeopardize theuser's safety or the safety of others.

Note:To alert following vehicles to slipperyroad conditions you discover, operateyour hazard warning flashers asappropriate.

88

Acceleration Slip Control (ASR)

The acceleration slip control willengage at all vehicle speeds, if one orboth drive wheels begin to lose tractionand spin due to excessive acceleration.While engaged, the yellow functionindicator in the speedometer lights up.With the acceleration slip controlengaged, the brake is applied to thespinning drive wheel until it regainssufficient traction. If both drive wheelslose traction and spin, the brake isapplied to both drive wheels andsimultaneously, engine torque islimited.

As traction on the road surfaceincreases, the allowable engine torquealso increases again and the brake is nolonger applied to drive wheels.

Caution!

If the vehicle is towed with the frontaxle raised (see Towing the vehicle inIndex), the key must not be in steeringlock position 2. Otherwise, theacceleration slip control willimmediately be engaged and will applythe rear wheel brakes.

Notes:With the key in steering lock position2, the yellow function indicator lampand the yellow ASR warning lamp inthe instrument cluster come on. Theymust go out with the engine running.

If the ASR warning lamp comes onwith the engine running, a malfunctionhas been detected. Pressing theaccelerator pedal will require greatereffort. Only partial engine output isavailable.Have the acceleration slip controlchecked at your authorized Mercedes-Benz dealer as soon as possible.

Driving the vehicle with varied sizetires will cause the wheels to rotate atdifferent speeds, therefore theacceleration slip control will activate(yellow ASR function indicator lamp ininstrument cluster comes on). For thisreason, all wheels, including the sparewheel, must have the same tire size.

When testing the parking brake on abrake test dynamometer, the key mustnot be in steering lock position 2.Otherwise, the acceleration slip controlwill immediately be engaged and willapply the rear wheel brakes.

In winter operation, the maximumeffectiveness of the acceleration slipcontrol can only be achieved with M +S radial-ply tires recommended byMercedes-Benz.

On vehicles equipped with accelerationslip control, the brake pad wearwarning lamp indicates brake pad wearfor the front as well as the rear brakes.

Emission Control

Certain systems of the engine serve tokeep the toxic components of theexhaust gases within permissible limitsrequired by law.

These systems, of course, will functionproperly only when maintained strictlyaccording to factory specifications.Any adjustments on the engine should,therefore, be carried out only byqualified MERCEDES-BENZtechnicians. Engine adjustments shouldnot be altered in any way. Moreover,the specified service and maintenancejobs must be carried out regularlyaccording to MERCEDES-BENZservicing requirements. For detailsrefer to the Maintenance Booklet.

Warning!

Inhalation of exhaust gas ishazardous to your health. Allexhaust gas contains carbonmonoxide, and inhaling it can causeunconsciousness and lead to death.Do not run the engine in confinedareas (such as a garage) which arenot properly ventilated. If you thinkthat exhaust gas fumes are enteringthe vehicle while driving, have thecause determined and corrected im-mediately. If you must drive underthese conditions, drive only with atleast one window fully open.

Traveling Abroad

Abroad, there is a widely-spreadMERCEDES-BENZ service network atyour disposal. If you plan to travel intoareas which are not listed in the indexof your dealer directory, you shouldrequest pertinent information from yourauthorized MERCEDES-BENZ dealer.

Winter Driving

Have your car winterized at yourauthorized MERCEDES-BENZ dealerbefore the onset of winter.

• Change the engine oil if the enginecontains an oil which is notapproved for winter operation. Forviscosity (SAE class) and fillingquantity, see "Fuels, Coolants,Lubricants, etc." see Index.

• Check engine coolantanticorrosion/antifreezeconcentration.

• Additive for the windshield washerand headlamp cleaning system: AddMB Concentrate "S" to a premixedwindshield washersolvent/antifreeze which isformulated for below freezingtemperatures (see Index).

• Test battery: Battery capacity dropswith decreasing ambienttemperature. A well charged batteryensures that the engine can alwaysbe started, even at low ambienttemperatures.

• Tires: We recommend M + S radialtires on all four wheels for thewinter season. Observe permissiblemaximum speed for M + S radialtires and the legal speed limit.

Note:In winter operation, the maximumefficiency of the acceleration slipcontrol or of the automatic lockingdifferential is only achieved with M +S radial tires.

Snow Chains

Use only snow chains that are testedand recommended by MERCEDES-BENZ. Your authorized MERCEDES-BENZ dealer will be glad to advise youon this subject.

Chains should only be used on the rearwheels. Follow the manufacturer'smounting instructions.

Snow chains should only be driven onsnow covered roads at speeds not toexceed 50 km/h (30 mph). Removechains as soon as possible whendriving on roads without snow.

Hood

To open:To unlock the hood, pull release lever(1) under the driver's side of theinstrument panel.

Important!

To avoid damage to the windshieldwipers or hood, open the hood onlywith wipers in the parked position.

Pull handle (2) out of radiator grill tostop, and open hood. Do not lift hoodat louvers of grill! Make certain thewindshield wiper arm is not foldedforward.

To close:Lower hood and let it drop into lockfrom a height of approx. 1 ft (30 cm),assisting with flat hands placed only onedges of hood (3).

To avoid hood damage, if hood isnot fully closed, re-open and repeatclosing procedure.

Warning!

To help prevent personal injury,stay clear of moving parts when thehood is open and the engine isrunning. Be sure the hood isproperly closed before driving.

The engine is equipped with atransistorized ignition system.Because of the high voltage it isdangerous to touch any components(ignition coil, distributor, spark plugsockets, ignition cables, diagnosticsocket) of the ignition system:

• with the engine running,• while starting the engine,• if the ignition is "on" and the

engine is turned manually.

We recommend that you do not openthe hood, if you see flames or smokecoming from the enginecompartment.

Example

Checking Coolant Level

The coolant level can be checkedvisually at the transparent coolantreservoir.To check the coolant level, the vehiclemust be parked on level ground.

Check coolant level only when coolantis cold:The coolant should reach the rib in thefiller neck. Also see marking (1) onreservoir.

Warning!

• Use extreme caution whenopening the hood if there are anysigns of steam or coolant leakingfrom the cooling system.

• Do not remove pressure cap oncoolant reservoir if enginetemperature is above 90°C(194°F). Allow engine to cooldown before removing cap. Thecoolant reservoir contains hotfluid and is under pressure.

• Using a rag, turn cap to firstnotch to relieve excess pressure.If opened immediately, hotscalding fluid and steam will beblown out under pressure,possibly causing personal injury,

• Do not spill antifreeze on hotengine parts. Antifreeze containsethylene glycol which may burn ifit comes into contact with hotengine parts. You can beseriously burned.

Adding Coolant

If coolant has to be added, a 50/50mixture of water and MBanticorrosion/antifreeze should beadded.

SL 320:The drain plugs for the coolingsystem are located on the right sideof the engine block and at the bottomof the radiator.

Example

Checking AutomaticTransmission Fluid Level

Dipstick locking lever

1. Break seal2. Release3. Engage

Regular automatic transmission fluidlevel checks are not required. For thisreason the dipstick opening is sealed.

When noticing fluid loss or gearshifting malfunctions, we recommendto have your authorized Mercedes-Benzdealer check the transmission fluidlevel.The transmission fluid level shouldonly be checked with the engine idling,parking brake engaged and selectorlever in position "P". The vehicle mustbe parked on level ground.Prior to the check, allow engine to idlefor approx. 1 to 2 minutes.To pull dipstick from tube, break sealby moving plastic pin (1) sideways.Then open cap by releasing lockinglever (2).Measure fluid level with the dipstickcompletely inserted and the lockinglever released (2).Extreme cleanliness must be observed!To wipe the dipstick, use a clean, lint-free cloth.To fill the transmission with fluid, pourit through a fine-mesh filter into thedipstick opening. Even the slightestimpurity may cause operationaltroubles.

The level of the transmission fluid isdependent upon its temperature. Two setsof maximum and minimum fluid levelmarks on the dipstick are applicablereferences only if the transmission fluidhas either reached its normal operatingtemperature of 176°F (80°C), or itstemperature is 86°F (30°C).

Important!

The fluid level must not exceed thedipstick maximum mark. Drain or siphonexcess fluid, if required.Then push dipstick all the way in andswing locking lever downwards (3).

Note:Damage to transmission caused bycontamination of transmission fluid oroverfilling of transmission may result inserious transmission damage which is notcovered by the Mercedes-Benz LimitedWarranty.

Vehicle Jack

1. Jack arm2. Jack base3. Tool kit

See illustration for proper storage ofjack.Before storing the jack, the jack arm(1) must be lowered almost to the base(2) of the jack.

Note:First remove the vehicle jack, then thespare wheel; reinstall in reverse order.

Warning!

The jack is designed exclusively forjacking up the vehicle at the jacktubes built into either side of thevehicle. Use the jack only to lift thevehicle during a wheel change. Neverget beneath the vehicle while it issupported by the jack. Keep handsand feet away from the area underthe lifted vehicle. Always firmly setparking brake and block wheelsbefore raising vehicle with jack.

Do not disengage parking brakewhile the vehicle is raised. Be certainthat the jack is always vertical whenin use, especially on hills. Lower thevehicle onto sufficient capacityjackstands before working under thevehicle.

Vehicle Tools

The vehicle tools (3) are located belowthe jack.

Wheels

Replace rims or tires with the samedesignation, manufacturer and type asshown on the original part. See yourauthorized MERCEDES-BENZ dealerfor further information.

Warning!

Do not mix different tire con-struction types (i.e. radial, bias, andbias-belted) on your car becausehandling may be adversely affectedand may result in loss of control.

See your authorized MERCEDES-BENZ dealer for information on testedand recommended rims and tires forsummer and winter operation. Theycan also offer advice concerning tireservice and purchase.

101

Tire Replacement

Front tires should be replaced in sets.Furthermore - in the event of tirereplacement - the spare wheel, ifpossible, should be used on the rearaxle. Rims and tires must be of thesame size. For dimensions, see"Technical Data".

We recommend that you break in newtires for approx. 100 km (60 miles) atmoderate speed. It is imperative thatthe wheel mounting bolts beretightened after approx. 60 -300 miles(100 to 500 km).

On new vehicles retightening is carriedout during the 1st inspection.Retightening is also necessarywhenever wheels are fitted, e.g. whenthe spare wheel is used for the firsttime or when a set of wheels with M +8 tires is installed.Tightening torque: 80 ft. lb (110 Nm).

For rim and tire specifications, refer to“Technical Data”.

Warning!

Worn, old tires can cause accidents.If the tire tread is badly worn, or ifthe tires have sustained damage,replace them.

When replacing rims, use onlygenuine MERCEDES-BENZ wheelbolts (identified by Mercedes star)specified for the rim type. Failure todo so can result in the bolts loosen-ing and possibly an accident

Rotating Wheels

The wheels can be rotated according tothe degree of tire wear while retainingthe same direction of travel.

Rotating, however, should be carriedout at a mileage of 3000-6000 miles(5000-10000) km, before the charac-teristic tire wear pattern (shoulder wearon front wheels and tread center wearon rear wheels) becomes visible, asotherwise the driving propertiesdeteriorate.

Important!

Unidirectional snow tires must alwaysbe mounted with arrow on tire sidewallpointing in direction of vehicle forwardmovement.

Note:Thoroughly clean the inner side of thewheels any time you rotate the wheelsor wash the vehicle underside.

The use of retread tires is notrecommended. Retread tires mayadversely affect the handlingcharacteristics and safety of thevehicle.Dented or bent rims cause tire pressureloss and damage to the tire beads. Forthis reason, check rims for damage atregular intervals.The rim flanges must be checked forwear before a tire is mounted.Remove burrs, if any.

102

Warning!

The jack is designed exclusively forjacking up the vehicle at the jacktubes built into either side of thevehicle. Use the jack only to lift thevehicle during a wheel change. Neverget beneath the vehicle while it issupported by the jack. Keep handsand feet away from the area underthe lifted vehicle. Always firmly setparking brake and block wheelsbefore raising vehicle with jack.

Do not disengage parking brakewhile the vehicle is raised. Be certainthat the jack is always vertical whenin use, especially on hills. Lower thevehicle onto sufficient capacityjackstands before working under thevehicle.

Changing Wheels

Move vehicle to a level area which is asafe distance from the roadway.

1. Set parking brake and turn onhazard warning flasher.

2. Select 1st or reverse gear in vehicleswith manual transmission or position"P" in vehicles equipped with auto-matic transmission.

3. Prevent vehicle from rolling away byblocking wheels with wheel chocksor sizable wood block or stone (notsupplied with, vehicle). Whenchanging a wheel on a hill, placechocks on the downhill side blockingboth wheels of the other axle. On alevel road, place onechock in front of and one behind thewheel that is diagonally opposite tothe wheel being changed.

4. Unfold wrench, loosen but do notremove the wheel bolts yet.

103

5. Remove the protective cover fromthe jack support tube opening byinserting a screwdriver in theopening and prying it out.

The tube openings are locateddirectly behind the front wheelhousings and in front of the rearwheel housings.

6. Insert jack arm fully into thetube hole up to the stop.Position the jack so that it isalways vertical (plumb-line) asseen from the side (see arrow),even if the vehicle is parked onan incline.

7. Jack up the vehicle until thewheel is clear of the ground.

8. Unscrew wheel bolts completely.Keep bolt threads protected fromdirt and sand. While removing thelast bolt, hold wheel against hub toavoid paint damage on rim.

9. Remove wheel. Grip wheel fromsides. Keep hands from beneath thewheels.

10. Screw the alignment bolt (1)supplied in the tool kit into theupper-most threaded hole.

Warning!

Always replace wheel bolts that aredamaged or rusted.Never apply oil or grease to wheelbolts threads.Damaged wheel hub threads shouldbe repaired immediately.

104

11. Install spare wheel on wheelhub. Insert wheel bolts andtighten them slightly.To avoid paint damage, placewheel flat against hub and hold itthere while installing first wheelbolt. Unscrew the alignment boltto install the last wheel bolt.

12. Lower car. Remove jack andinsert jack tube cover.

13. Fold wrench together andtighten the five bolts evenly,following the sequenceillustrated above, until all boltsare tight.Observe a tightening torque of 80ft. lb (110 Nm).

14. Correct tire pressure.

Important!

When installing new wheels themounting bolts must be retightenedafter approx. 60 - 300 miles (100 to500 km).

Before storing the jack, the jack armmust be lowered almost to the base ofthe jack. Store the spare wheel first andthen the vehicle jack.

Warning!

Incorrect mounting bolts orimproperly tightened mounting boltscan cause the wheel to come off. Thiscould cause an accident Be sure touse the correct mounting bolts.

105

Tire Inflation Pressure

A table (see fuel filler flap) lists the tireinflation pressures specified forMercedes Benz recommended tires aswell as for the varying operatingconditions.

Important!

Tire pressure differs by approx. 1.5 psi(0.1 bar) per 18°F (10°C) of airtemperature change. Keep this in mindwhen checking tire pressure inside agarage - especially in the winter.

Example:

If garage temperature =approx. + 68 ° F (+ 20 ° C) andambient temperature =approx. + 32° F (0°C) then the adjustedair pressure = specifiedair pressure + 3 psi (+ 0.2 bar).

Tire pressures listed for light loads areminimum values offering high drivingcomfort.

Increased inflation pressures for heavyloads produce favorable handlingcharacteristics with lighter loads andare perfectly permissible. The ride ofthe vehicle, however, will becomesomewhat harder.

Tire temperature and pressure increasewith the vehicle speed. Tire pressureshould therefore only be corrected oncold tires. Correct tire pressure in warmtires only if pressure has dropped be-low the pressure listed in the table andthe respective operating conditions aretaken into consideration.

An underinflated tire due to a slowleak (e.g. due to a nail in the tire) maycause damage such as tread separation,bulging etc.. Regular tire pressurechecks (including the spare tire) atintervals of no more than 14 days aretherefore essential.If a tire constantly loses air, it shouldbe inspected for damage.

Warning!

Do not overinflate tires, overinflatingtires can result in sudden deflation(blowout) because they are morelikely to become punctured ordamaged by road debris, potholesetc.. Follow recommended inflationpressures.

Do not overload the tires byexceeding the specified vehiclecapacity weight (as indicated by thelabel on the driver's door latch post).Overloading the tires can overheatthem, possibly causing a blowout.

106

Battery

The maintenance-free battery is locatedin the trunk behind the right-hand coverpanel.

The service life of the battery isdependent on its condition of charge.The battery should always be keptsufficiently charged in order to last anoptimum length of time.

Therefore, we strongly recommendthat you have the battery chargechecked frequently, and corrected ifnecessary, especially if you use thevehicle less than approximately 200miles (300 km) per month, mostly forshort distance trips, or if it is notused for long periods of time.

Only charge a battery with a batterycharger after it has been disconnectedfrom the vehicle electrical circuit.

When removing and connecting thebattery, always make sure that allelectrical consumers are off and thekey is in steering lock position 0.

While the engine is running the batteryterminal clamps must not be loosenedor detached, otherwise the alternatorand other electronic components wouldbe damaged.

Battery Recycling

Batteries contain materials that canharm the environment withimproper disposal.

Large 12 Volt storage batteries containlead, and smaller watch-type batteries(such as in the Infrared RemoteControl Unit) may contain mercury.

Recycling of batteries is thepreferred method of disposal.

Many states require sellers of batteriesto accept old batteries for recycling.

Warning!

Never lean over batteries whileconnecting or jump starting, youmight get injured.

Battery fluid contains sulfuric acid.Do not allow this fluid to come incontact with eyes, skin or clothing.In case it does, immediately flushaffected area with water and seekmedical help.

A battery will also produce hydrogengas, which is flammable andexplosive. Keep flames or sparksaway from battery, avoid improperconnection of jumper cables,smoking, etc..

107

Before replacing a blown fuse,determine the cause of the short circuit.

Spare fuses are supplied inside the fusebox. Observe amperage and color offuse.

Always use a new fuse for re-placement. Never attempt to repair orbridge a blown fuse.

Warning!

Failure to follow these directions canlead to a battery explosion andpersonal injury.Read, all instructions beforeproceeding.

Proceed as follows:

1. Position the vehicle with thecharged battery so that the jumpercables will reach, but never let thevehicles touch. Make sure thejumper cables do not have loose ormissing insulation.

2. On both vehicles:• Turn off engine and all lights

and accessories, except hazardflashers or work lights.

• Apply parking brake andshift selector lever toposition "P" (neutral formanual transmission).

Important!

3. Clamp one end of the first jumpercable to the positive ( + ) terminalof the discharged battery and theother end to the positive (+)terminal of the charged battery.Make sure the cable clamps do nottouch any other metal parts.

4. Clamp one end of the secondjumper cable to the groundednegative (-) terminal of the chargedbattery and the final connection toa grounded heavy metal bracket inthe engine compartment or on theengine of the disabled vehicle.Make sure the cables are not on ornear pulleys, fans, or other partsthat will move when the vehiclewith the charged battery is started.

111

Important!

5. Start engine of the vehicle withthe charged battery and run athigh idle. Then start engine ofthe disabled vehicle in the usualmanner.

6. After the engine has started,remove jumper cables byreversing the above installationsequence exactly, starting withthe jumper cable connected toa heavy metal bracket in thedisabled vehicle's enginecompartment. When removingeach clamp, make sure that it doesnot touch any other metal while theother end is still attached.

Warning!

Never lean over batteries whileconnecting or jump starting, youmight get injured.

Battery fluid contains sulfuric acid.Do not allow this fluid to come incontact with eyes, skin or clothing. Incase it does, immediately flushaffected area with water, and seekmedical help.

A battery will also produce hydrogengas, which is flammable and veryexplosive. Keep flames or sparksaway from battery, avoid improperconnection of jumper cables,smoking, etc..

Important!

A discharged battery can freeze atapprox. + 14°F (-10°C). In that case, itmust be thawed out before jumpercables are used.

Jumper cable specifications:

• Minimum cable cross-section of25 mm2 or approx. 2 AWG

• Maximum length of 11.5 ft(3.5 m).

112

Towing of Vehicle

The rear towing eye is located at theright, below the bumper. The fronttowing eye is located on the passengerside behind a flap in the bumper panel.

Flap removal: Insert finger in recess offlap and pull flap out.

Flap installation: Engage flap at bottomand press in top securely.

We recommend that the vehicle betransported using flat bed equipment.This method is preferable to other typesof towing.

The vehicle may be towed with all ofthe wheels on the ground and theselector lever in position "N" fordistances up to 30 miles (50 km) and ata speed not to exceed 30 mph (50km/h).To positively avoid a possibility ofdamage to the transmission, however,we recommend to disconnect the driveshaft at the rear axle drive flange onany towing beyond a short tow to anearby garage.Do not tow with sling-type equipment.Towing with sling-type equipmentover bumpy roads will damage radiatorand supports.The use of wheel lift equipment willdamage engine oil pan.

Cleaning and Care of the Vehicle

Warning!

Many cleaning products can behazardous. Some are poisonous,others are flammable. Always followthe instructions on the particularcontainer. Always open your car'sdoors or windows when cleaning theinside.Never use fluids or solvents that arenot designed for cleaning your car.

In operation, your vehicle is subjectedto varying external influences which, ifgone unchecked, can attack the paint-work as well as the underbody andcause lasting damage.

Such damage is caused not only byextreme and varying climaticconditions, but also by air pollution,road salt, tar, gravel and stonechipping. Grease and oil, fuel, coolant,brake fluid, bird droppings, tree resins,etc. should be removed immediately to

avoid paint damage. Frequentwashing, however, reduces and/oreliminates the aggressiveness andpotency of the above adverse in-fluences.

More frequent washings are necessaryto deal with unfavorable conditions; forexample, near the ocean, in industrialareas (smoke, exhaust emissions), orduring winter operation.

You should check your vehicle fromtime to time for stone chipping or otherdamage. Any damage should berepaired as soon as possible to preventthe start of corrosion.

In doing so, do not neglect theunderside of the car. A prerequisite fora thorough check is a washing of theunderbody followed by a thoroughinspection. Damaged areas need to bereundercoated.

Your vehicle has been treated at thefactory with a wax-base rustproofing inthe body cavities which will fast for thelifetime of the vehicle. Post-productiontreatment is neither

necessary nor recommended byMERCEDES-BENZ because of thepossibility of incompatibility betweenmaterials used in the productionprocess and others applied later.

We have selected car-care products andcompiled recommendations which arespecially matched to our vehicles andwhich always reflect the latest techno-logy. You can obtain MB car-careproducts at your authorizedMERCEDES-BENZ dealer.

Scratches, corrosive deposits, corrosionor damage due to negligent or incorrectcare cannot always be removed orrepaired with the car-care products re-commended here. In such cases it isbest to seek aid at your authorizedMERCEDES-BENZ dealer.

The following topics deal with thecleaning and care of your vehicle andgive important "how-to" information aswell as references to recommendedMB car-care products.

114

Engine Cleaning

Corrosion protection, such as MBAnticorrosion Wax should be appliedto the engine compartment after everyengine cleaning. Before applying, allcontrol linkage bushing should belubricated. The V-belt and all pulleysshould be protected from any wax.

Car Washing

Before washing your vehicle, removeinsect residues, MB Insect Remover isrecommended. Do not use hot water orwash your car in direct sunlight. Useonly a mild car wash detergent, such asMB Autoshampoo.

During vehicle operation, the boilingpoint of the brake fluid is continuouslyreduced through the absorption ofmoisture from the atmosphere. Underextremely hard operating conditions,this moisture content can lead to theformation of bubbles in the system thusreducing the system's efficiency.

The brake fluid must therefore bereplaced every two years, preferablyin the spring.

It is recommended to use only brakefluid approved by Mercedes Benz.Your authorized Mercedes-Benz dealerwill provide you with additionalinformation.

Premium Unleaded Gasoline

Caution!

To maintain the engine's durability andperformance, premium unleadedgasoline must be used. If premiumunleaded is not available and lowoctane fuel is used, follow theseprecautions:

• have the fuel tank filled onlypartially with unleaded regularand fill up with premium unleaded as soon as possible,

• avoid full throttle driving andabrupt acceleration,

• do not exceed an engine speedof 3000 rpm, if the vehicle isloaded with a light load such astwo persons and no luggage,

• do not exceed 2/3 of maximumaccelerator pedal position, if thevehicle is fully loaded or operatingin mountainous terrain.

Fuel Requirements

Use only Premium unleaded meetingASTM standard D 439:

The octane number (posted at thepump) must be 91min. It is an averageof both, the Research (R) octanenumber and the Motor (M) octanenumber: [(R + M)/2]. This is alsoknown as ANTI-KNOCK INDEX.

Unleaded gasoline containingoxygenates such as Ethanol, IPA, IBAand TBA can be used provided theratio of any one of these oxygenates togasoline does not exceed 10%, MTBEnot to exceed 15%.

The ratio of Methanol to gasoline mustnot exceed 3% plus additionalcosolvents.

Using mixtures of Ethanol andMethanol is not allowed. Gasohol,which contains 10% Ethanol and 90%unleaded gasoline, can be used.

These blends must also meet all otherfuel requirements such as resistance tospark knock, boiling range, vaporpressure etc..

Gasoline Additives

A major concern among enginemanufacturers is carbon build upcaused by gasoline. Mercedes-Benzrecommends to use only qualitygasoline containing additives thatprevent the build up of carbon deposits.

After an extended period of using fuelswithout such additives, carbon depositscan build up especially on the intakevalves and in the combustion area,leading to engine performanceproblems such as:

• warm-up hesitation,• unstable idle,• knocking/pinging,• misfire,• power loss.

Damages or malfunctions resultingfrom poor fuel quality are not coveredby the Mercedes-Benz LimitedWarranty.

139

Coolants

The engine coolant is a mixture of waterand anticorrosion/anti-freeze, whichprovides:

• corrosion protection• freeze protection• boiling protection (by increasing

the boiling point).

The cooling system was filled at thefactory with a coolant providing freezeprotection to approx. -22 °F (-30 °C) andcorrosion protection.

The coolant solution must be used yearround to provide the necessary corrosionprotection and increase in the boil-overprotection. You should have it replacedevery 3 years.

To provide the important corrosionprotection, the solution must be at least45% anticorrosion/antifreeze (equals afreeze protection to approx. -22 °F[-30 °C]). If you use a solution that ismore than 55% anticorrosion/antifreeze(freeze protection to approx. -49 °F[-45°C]), the engine temperature willincrease due to the lower heat transfercapability of the solution.

Therefore, do not use more than thisamount of anti-corrosion/antifreeze.If the coolant level is low, water andMB anticorrosion/antifreeze should beused to bring it up to the proper level(have cooling system checked for signsof leakage).

The water in the cooling system mustmeet minimum requirements, which areusually satisfied by normal drinkingwater. If you are not sure about thewater quality, consult your authorizedMercedes-Benz dealer.

Anticorrosion/antifreeze

Your vehicle contains a number ofaluminum parts. The use of aluminumcomponents in motor vehicle enginesnecessitates that anticorrosion/antifreeze coolant used in such enginesbe specifically formulated to protect thealuminum parts. (Failure to use suchanticorrosion/antifreeze coolant willresult in a significantly shortenedservice life.)

Therefore the following product isstrongly recommended for use in yourcar: Mercedes-BenzAnticorrosion/Antifreeze Agent.

Before the start of the winter season (oronce a year in the hot southern regions),you should have the anticorrosion/antifreeze concentration checked. Thecoolant is also regularly checked eachtime you bring your vehicle to yourauthorized Mercedes-Benz dealer formaintenance service.

Consumer Information

This has been prepared as required of allmanufacturers of passenger cars underTitle 49, Code of U.S. FederalRegulations, Part 575 pursuant to the"National Traffic and Motor VehicleSafety Act of 1966".

Uniform Tire Quality Grading

Refer to the tire sidewall for the specifictire grades for the tires with which thisvehicle is equipped.All passenger car tires must conform tofederal safety requirements in addition tothese grades.

Treadwear

The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear one and one-half (11/2) times aswell on the government course as a tiregraded 100. The relative performance oftires "depends upon the actual conditionsof their use, however,

and may depart significantly from thenorm due to variations in driving habits,service practices and differences in roadcharacteristics and climate.

Traction "A", "B", "C"

The traction grades, from highest tolowest, are "A", "B" and "C" and theyrepresent the tire's ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked "C" may have poor tractionperformance.

Warning!

The traction grade assigned to thistire is based on braking (straightahead) traction tests and does notinclude cornering (turning) traction.

Temperature "A", "B", "C"

The temperature grades are "A" (thehighest). "B" and "C", representing thetire's resistance to the generation of heatand its ability .to dissipate heat when

tested under controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can causethe material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tire fail-ure. The grade "C" corresponds to alevel of performance which allpassenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 109 Grades "B" and "A" representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.

Warning!

The temperature grade for this tire isestablished for a tire that is properlyinflated and not overloaded.Excessive speed, underinflation, orexcessive loading, either separately orin combination, can cause excessiveheat build up and possible tirefailure.
