The First 1000 Miles (1500km)
The more cautiously you treat your vehicle during the break-in period, the more satisfied you will be with its performance later on. Therefore, drive your vehicle during the first 1000 miles (1500 km) at moderate vehicle and engine speeds.
During this period, avoid heavy loads (full throttle driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended to brake the vehicle by manually shifting to a lower gear. We recommend to select positions "3", "2" or "1" only at moderate speeds (for hill driving).
After 1000 miles (1500 km) speeds may be gradually increased to the permissible maximum.
Check Regularly and Before a Long Trip
See Index

Catalytic Converter
Caution!
Warning!
Your MERCEDES-BENZ is equipped with monolithic type catalytic converters, an important element in conjunction with the oxygen sensor to achieve substantial control of the pollutants in the exhaust emissions. Keep your vehicle in proper operating condition by following our re­commended maintenance instructions as outlined in your Maintenance Booklet.
To prevent damage to the catalytic converters, use only premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, excessive unburned fuel may reach the catalytic converter causing it to overheat.
As with any vehicle, do not idle, park or operate this vehicle in areas where combustible materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited.

Starting and Turning off the Engine
Cold Engine
Important!
Starter Lock-Out
Important!
The engine can only be started, if the vehicle was unlocked from the outside.
Before Starting
Engage parking brake and ensure gearshift lever is in neutral (selector lever position "P" or "N" on automatic transmissions). Turn key in steering lock to position 2. The charge indicator lamp should come on.
Note: If transmit button of the remote control is inadvertently pressed again prior to starting the engine, the start lock-out is activated. In this case press transmit button again to deactivate the start lockout.
Do not depress accelerator. Turn key in steering lock clock-wise to the stop. Do not depress accelerator. Release key only when the engine is firing regularly.
Hot Engine
Do not depress accelerator. Turn key in steering lock clock-wise to the stop. If the engine has not fired after approx. 4 seconds, depress accelerator and continue cranking until the engine is firing regularly. Release key and back off accelerator. At very high coolant temperatures the engine starting time can be shortened if the accelerator is depressed slowly at the beginning of the starting process.
Turning Off
Turn the key in the steering lock to position 0 to stop the engine.
The key can only be removed with the selector lever in position
"P".
Due to the installed starter non-repeat feature, the key must be turned completely to the left before attempting to start the engine again.
Observe the oil pressure gauge immediately after starting the engine. In a very cold engine the oil pressure will rise slowly after the engine has started. Do not speed up the engine before pressure is registered on the pressure gauge. If you do not see the gauge register oil pressure, stop the engine and have it checked.
The battery charge indicator lamp should go out as soon as the engine has started.
In areas where temperatures frequently drop below -4°F (-20°C) we recommend that an engine block heater be installed. Your authorized Mercedes-Benz dealer will advise you on this subject.

Driving Instructions
Warning!
If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard flashers, carefully slow down, and drive with caution to an area which is a safe distance from the roadway. Inspect the tires and under the vehicle for possible damage. If the vehicle or tires appear unsafe, have it towed to the nearest Mercedes-Benz or tire dealer for repairs.
Power Assistance
Warning!
When the engine is not running, the brake and steering systems are without power assistance. Under these circumstances, a much greater effort is necessary to stop or steer the vehicle.
Brakes
Warning!
After driving in heavy rain for some time without applying the brakes or through water deep enough to wet brake components, the first braking action may be somewhat reduced and increased pedal pressure may be necessary. Be sure to maintain a safe distance from vehicles in front. Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads. It can also result in the brakes overheating thereby significantly reducing their effectiveness. It may not be possible to stop the car in sufficient time to avoid an accident.
The condition of the parking brake system is checked each time the car is in the shop for the required maintenance.
All checks and maintenance work on the brake system should be carried out by an authorized Mercedes-Benz dealer.
If the parking brake is released and the brake warning lamp in the instrument cluster stays on, the brake fluid level in the reservoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized Mercedes-Benz dealer immediately.
Install only brake pads and brake fluid recommended by Mercedes-Benz.
Warning!
If other than recommended brake pads are installed, or other than recommended brake fluid is used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired.
16
Page 17
Caution!
When driving down long and steep grades, relieve the load on the brakes by shifting into "3", "2" or "1" (for models SL 500 and SL 600). This helps prevent overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some time, rather than immediately parking, so the air stream will cool down the brakes faster.
Tires
Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a depth of approximately
1
/16in (2 mm), at which point the tire is considered worn and should be replaced. The tread wear indicator appears as a solid band across the tread.
Warning!
Do not allow your tires to wear down too far. With less than
1
/16in (1.5 mm) of tread, the adhesion properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions), the tire traction varies widely.
Specified tire pressures must be maintained. This applies particularly if the tires are subjected to high loads (e.g. high speeds, heavy loads, high ambient temperatures).
Warning!
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the car. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build-up and possibly a fire.
Aquaplaning
Depending on the depth of the water layer on the road, aquaplaning may occur, even at low speeds and with new tires. Avoid track grooves in the road and apply brakes cautiously in the rain.
17
Page 18
Tire Traction
Tire Speed Rating
Parking
The safe speed on a wet, snow covered or icy road is always lower than on a dry road. You should pay particular attention to the condition of the road as soon as the prevailing temperatures fall close to the freezing point.
Warning!
If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.
We recommend M + S radial-ply tires for the winter season for all four wheels to insure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance as compared with summer tires. Stopping distance, however, is still considerably greater than when the road is wet or dry.
Your vehicle is factory equipped with "Z"-rated tires.
Despite the tire rating, local speed limits should be obeyed. Use prudent driving speeds appropriate to prevailing conditions.
Warning!
Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires.
Exceeding the maximum speed for which tires are rated can lead to sudden tire failure causing loss of vehicle control and resulting in personal injury and possible death.
Warning!
To reduce the risk of personal injury as a result of vehicle movement,
turning off the engine and
before leaving 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 automatic transmissions).
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 brake whenever parking or leaving the vehicle. In addition, engage first or reverse gear (selector lever position "P"). When parking on hills, always set the parking brake.
18
Page 19
Winter Driving Instructions
The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering action. Do not use the cruise control system under such conditions.
When the vehicle is in danger of skidding, declutch, or in case of automatic transmission move selector lever to position "N". Try to keep the vehicle under control by corrective steering action. Road salts and chemicals can adversely affect braking efficiency. Increased pedal force may become necessary to produce the normal brake effect. We therefore recommend depressing the brake pedal periodically when traveling at length on salt-strewn roads. This can bring road salt impaired braking efficiency back to normal. A prerequisite is, however, that this is done without endangering other drivers on the road.
If the vehicle is parked after being driven on salt treated roads, the braking efficiency should be tested as soon as possible after driving is resumed while observing the safety rules in the previous paragraph.
Warning!
If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from around the vehicle with engine running. Otherwise, deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death. To assure sufficient fresh air ventilation, open a window slightly on the side of the car that is out of the wind.
Passenger Compartment
Warning!
Always fasten items being carried as securely as possible. In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle, and cause injury to vehicle occupants unless the items are securely fastened in the vehicle.

The system will not heat or cool any quicker by setting a higher or lower temperature. The automatic climate control only operates with the engine running. Higher engine rpm results in higher coolant compressor rpm, thereby increasing cooling capacity.
The automatic climate control removes considerable moisture from the air during operation in the cooling mode. It is normal for water to drip on the ground through ducts in the underbody.
Note: Keep the air intake grille in front of windshield free of snow and debris.
Dust Filter
Dust particles (down to a certain size) and pollen are filtered out before outside air enters the passenger compartment through the air distribution system.
Important!
This vehicle is equipped with an air conditioner system that uses HFC-134a (ozone-friendly hydro-fluorocarbon) as a refrigerant.
Repairs should always be performed by a qualified technician, and refrigerant should be collected in a recovery system for recycling.

Seat Belts and Supplemental Restraint System (SRS)
Your vehicle is equipped with lap­shoulder seat belts, emergency tensioning retractors for the seat belts, driver airbag and knee bolster and passenger airbag and knee bolster.
Seat Belts
Important!
Laws in most states and all Canadian provinces require seat belt use.
All states and provinces require use of child restraints that comply with U.S. Federal Motor Vehicle Safety Standard 213 and Canadian Motor Vehicle Safety Standard 213.1. We strongly recommend their use.
Seat Belt Warning System
With the key in steering lock position 2, an audible warning sounds for a short time if the driver's seat belt is not fastened.
Warning!
Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. You and your passengers should always wear seat belts. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you can hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed.
In the same crash, the possibility for injury or death is lessened with your seat belt buckled.
The seat belts provide protection only with the backrest locked in place. If the seat belt warning lamp does not go out, but is instead lit con­tinuously, then a backrest is not engaged in its lock.
Never ride in a moving vehicle with the seat back reclined. Sitting in an excessively reclined position can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat back and seat belts provide the best restraint when the wearer is in an upright position and belts are properly positioned on the body.

Fastening of Seat Belts
Pull belt with latch plate (1) across shoulder and lap. Push latch plate (1) into buckle (2) until it clicks. The lap belt should be positioned as low as possible on your hips and not across the abdomen. Do not twist the belt. A twisted seat belt may cause injury. For safety reasons, avoid adjusting the seat or seat back into positions which could affect the correct seat belt position.
41
Page 42
Unfastening of Seat Belts
Push in the red button (3) in the belt buckle (2).
Allow the retractor to completely rewind the seat belt by guiding the latch plate (1).
Operation: The inertia reel stops the belt from unwinding during sudden vehicle stops or when quickly pulling on the belt.
The locking function of the reel may be checked by quickly pulling on the belt.
The emergency tensioning retract-ors tighten the fastened seat belts during frontal and front-angled impacts exceeding the first threshold of the SRS (see Index).
Note: For cleaning and care of the seat belts, see Cleaning and Care of the Vehicle in Index.
Warning!
USE SEAT BELTS PROPERLY.
Each occupant should wear their seat belt at all times, because seat belts help re duce the likelihood of and potential severity of injuries in accidents, including roll­overs. "SRS" (driver airbag, passenger airbag), "ETR" (seat belt emergency tensioning retractors), and knee bolsters are designed to enhance the protection offered to properly belted occupants in certain frontal impacts which exceed preset deployment thresholds.

Position the lap belt as low as possible on your hips and not across the abdomen. If the belt is positioned across your abdomen, it could cause serious injuries in a crash.
be used for more than one person at a time. Do not fasten a seat belt around a person and objects.
Belts should not be worn twisted. In a crash, you wouldn't have the full width of the belt to take impact forces. The twisted belt against your body could cause injuries.
Pregnant women should also use a lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen.
USE CHILD RESTRAINTS PROPERLY.
Infants and small children must be seated in an infant or child restraint system, which is properly secured by a lap belt or lap belt portion of a lap-shoulder belt. Children could be en dangered in an accident if their child restraints are not properly secured in the vehicle.
Rear-facing child restraints must not be used in the front seat. They could be struck by the airbag when it inflates in a crash. If this happens, a child in the restraint could be seriously injured.
Children too big for child restraint systems should use regular seat belts. Position shoulder belt across chest and shoulder, not face or neck. A booster seat may be necessary to achieve proper belt positioning.
43
Page 44
Supplemental Restraint System (SRS)
The SRS uses two crash severity levels (thresholds) to activate either the ETR or airbag or both. Activation depends on the direction and severity of the impact, exceeding the thresholds and fastening of the seat belt.
Emergency Tensioning Retractor (ETR)
The seat belts are equipped with emergency tensioning retractors. These tensioning retractors are located in each belt's inertia reel and become operationally ready with the key in steering lock position 1 or 2.
In cases of other frontal impacts, roll­overs, certain side impacts, rear collisions, or other accidents without frontal forces, the emergency tensioning retractors will not be activated. The driver and passenger will then be protected by the fastened seat belts and inertia reel in the usual manner.
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 systems operate independently from each other.
The emergency tensioning retractors are designed to activate only when the seat belts are fastened during frontal and front-angled impacts exceeding the first threshold of the SRS. They remove slack from the belts in such a way that the seat belts fit more snugly against the body, restricting its forward movement as much as possible.
For seat belt and emergency tensioning retractor safety guidelines, see Safety Guidelines in Index.

Page 45
Airbags
1. Driver airbag
2. Front passenger airbag
3. Side impact airbag
The most effective occupant restraint system yet developed for use in production vehicles is the seat belt. In some cases, however, the protective effect of a seat belt can be further enhanced by an airbag.
The driver airbag is located in the steering wheel hub. The passenger airbag is located in the dashboard ahead of the passenger.
The side impact airbags are located in the doors. In conjunction with wearing the seat belts with emergency tensioning retractors, the airbags can provide increased protection for the driver and passenger in certain major frontal and front-angled and side impacts.
The operational readiness of the airbag system is verified by the indicator lamp "SRS" in the instrument cluster. If no fault is detected, the lamp will go out after approximately 4 seconds; after the lamp goes out, the system continues to monitor the components and circuitry of the airbag system
and will indicate a malfunction by corning on again. The following system components are monitored or undergo a self-check: crash-sensor, airbag ignition circuits, driver and passenger seat belt buckles. Initially, when the key is turned from steering lock position 0 to positions 1 or 2, malfunctions in the crash-sensor are detected and indicated (the "SRS" indicator lamp stays on longer than 4 seconds).
In the operational mode, after the indicator lamp has gone out following the initial check, inter­ruptions and short circuits in the
45
Page 46
airbag ignition circuit and in the driver and passenger seat belt buckle harnesses, and low voltage in the entire system are detected and indicated. In the event a malfunction of the "SRS" is indicated as outlined above, the "SRS" may not be operational. We strongly recommend that you visit an authorized Mercedes-Benz dealer immediately to have the system checked; otherwise the "SRS" may not be activated when needed.
Front Airbags
The driver and passenger front "SRS" airbags are designed to activate only in certain frontal and front-angled impacts. Both airbags may deploy, even if the passenger seat is unoccupied.
Side Airbags
The side impact "SRS" airbags are designed to activate only in certain side impacts. Only the impacted side airbag deploys.
Important!
The airbags are designed to activate only in certain frontal and front­angled impacts. Only during these types of impacts will they provide their supplemental protection. The driver and passenger should always wear the seat belts, otherwise it is not possible for the airbags to provide their intended supplemental protection.
In cases of other frontal impacts, roll-overs, certain side impacts, rear collisions, or other accidents without frontal forces, the airbags will not be activated. The driver and passenger will then be protected by the fastened seat belts.
We caution you not to rely on the presence of an airbag in order to avoid wearing your seat belt.
Important!
The "SRS" is designed to reduce the potential of injury in certain frontal and front-angled impacts which may cause injuries, however, no system available today can totally eliminate injuries and fatalities.
The activation of the "SRS" temporarily releases a small amount of dust from the air-bags. This dust, however, is neither injurious to your health, nor does it indicate a fire in the vehicle.
The service life of the airbags extends to the date indicated on the label located on the driver-side door latch post. To provide continued reliability after that date, they should be inspected by an authorized Mercedes-Benz dealer at that time and replaced when necessary.
The passenger side impact airbag may deploy, even if the seat is unoccupied.
46
Page 47
Warning!
It is very important for your safety to always be in a properly seated position and to wear your seat belt.
For maximum protection in the event of a collision always be in normal seated position with your back against the seat back. Fasten your seat belt and ensure that it is properly positioned on the body.
Since the airbag inflates with considerable speed and force, a proper seating position will keep you in a safe distance from the airbag:
Sit properly belted in an upright position with your back against the seat back.
Do not lean with your head or chest close to the steering wheel or dashboard.
Infants and small children should only be seated in an infant or child restraint which is properly secured by the seat belt.
Rear-facing child restraints must not be used in a front seat.
Failure to follow these instructions can result in severe injuries to you or other occupants.
For unobstructive inflation of side airbags, keep door pock-et lids closed.
Adjust the driver seat as far as possible rearward, still permitting proper operation of vehicle controls.
Adjust the passenger seat as far as possible rearward from the dashboard, especially when a child restraint is installed.
47

Safety Guidelines for the Seat Belt, Emergency Tensioning Retractor and Airbag
Warning!
Damaged belts or belts that were highly stressed in an accident must be replaced and their anchoring points must also be checked. Use only belts installed or supplied by an authorized Mercedes-Benz dealer.
Do not pass belts over sharp edges.
Do not make any modification that could change the effectiveness of the belts.
The "SRS" is designed to function on a one-time-only basis. An airbag or emergency tensioning retractor (ETR) that was activated must be replaced.
No modifications of any kind may be made to any components or wiring of the "SRS". This includes the installation of additional trim material, badges etc. over the steering wheel hub or front passenger airbag cover and installation of additional electrical/electronic equipment on or near "SRS" components and wiring.
Several airbag system com­ponents at the steering wheel get hot after the air-bag has inflated. Don't try to touch them.
Improper work on the system, including incorrect installation and removal, can lead to possible injury through an uncontrolled activation of the "SRS".
In addition, through improper work there is the risk of rendering the "SRS" inoperative. Work on the "SRS" must therefore only be performed by an authorized Mercedes-Benz dealer.
When scrapping the airbag unit or emergency tensioning retractor, it is mandatory to follow our safety instructions. These instructions are available at your authorized Mercedes­Benz dealer.
When you sell the vehicle we strongly urge you to give notice to the subsequent owner that it is equipped with an "SRS" by alerting him to the applicable section in the Owner's Manual.

Infants and Child Restraint Systems
We recommend that all infants and children be restrained at all times while the vehicle is in motion. The passenger seat has a special seat belt retractor for secure fastening of a child restraint. To use, fasten child restraint with seat belt: Follow child restraint instructions for routing. Then pull shoulder belt out completely. Slide switch located on side of passenger seat to position . Let the belt retract. It is now locked. Push down on child restraint to take up any slack.
Important!
The use of infant or child restraints is required by law in all 50 states and all Canadian provinces. Infants and small children should be seated in an infant or child restraint system, which is properly secured by the lap belt portion of the lap-shoulder belt, and that complies with U.S. Federal Motor Safety Standard 213
and Canadian Motor Vehicle Safety Standard 213.1. A statement by the child restraint manufacturer of compliance with this standard can be found on the instruction label on the restraint and in the instruction manual provided with the restraint. When using any infant or child restraint system, be sure to carefully read and follow all manufacturer's instructions for installation and use.
Warning!
Rear-facing child restraints must not be used in a front seat They could be struck by the airbag when it inflates in a crash. If this happens, a child in the restraint could be seriously injured.
Infants and small children should never be held on the lap while the vehicle is in motion. During an accident they would be almost impossible to hold, and could be crushed between the adult and the dashboard.
Infants and small children should never share a seat belt with another occupant During an accident, they could be crushed between the occupant and seat belt.
Children too big for child restraint systems should use regular seats belts. Position the shoulder belt across the chest and shoulder, not the face or neck. A booster seat may be necessary to achieve proper belt positioning.
When the child restraint is not in use, remove it from the car or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident.
U.S.A. Models only Since 1986 all U.S. child restraints comply with U.S. regulations without the use of a tether strap.
Canada Models only This vehicle can be equipped with tether anchorages for a top tether strap. Consult your authorized Mercedes­Benz dealer for installation of these anchorages.

Drinking and Driving
Driving Off
Warning!
Drinking and driving can be a very dangerous combination. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment. The possibility of a serious or even fatal accident is sharply increased when you drink and drive. Please don't drink and drive or allow a friend to drive when he has been drinking.
Test the brakes briefly after driving off. Perform this procedure only when the road is clear of other traffic. Warm up the engine smoothly. Do not place full load on the engine until the operating temperature has been reached.
Warning!
Keep driver's foot area clear at all times. Objects stored in this area may impair pedal movement.
Parking Brake
To engage, depress parking brake pedal. With the key in steering lock position 2, the brake warning lamp in the instrument cluster should come on brightly (function check for lamp). To release the parking brake, pull handle on instrument panel. The brake warning lamp in the instrument cluster should go out (also see brake warning lamp, page 88).

Page 77
Automatic Transmission
The automatic transmission selects individual gears auto­matically, dependent upon
Selector lever position
Accelerator position
Vehicle speed
Important!
When parking the car and before working on the vehicle with the engine running, firmly depress the parking brake pedal and shift the selector lever into "P".
Driving
The selector lever is automatically locked while in position "P". To move the selector lever out of position "P", the service brake pedal must be firmly depressed before the shift lock will release.
Shift selector lever to the desired position only when the engine is idling normally and the service brake is applied. Do not release the brake until ready to drive. The vehicle may otherwise start creeping when the selector lever is in drive or reverse position.
Warning!
It is dangerous to shift the selector lever out of "P" or "N" if the engine speed is higher than idle speed. If your foot is not on the brake pedal, the car could accelerate quickly forward or in reverse. You could lose control of the car and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.
Important!
After selecting any driving position from "N" or "P", wait a moment to allow the gear to fully engage before accelerating, especially when the engine is cold.
Accelerator position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full throttle) = downshifting to next lowest gear = maximum acceleration. Once the desired speed is attained, ease up on the accelerator ­the transmission shifts up again.
77
Page 78
Selector Lever Positions SL 320
The automatic gear shifting process can be adapted to specific operating conditions using the selector lever.
P Parking lock.
The parking lock is an additional safeguard to the parking brake when parking the vehicle. Engage only with the car stopped.
Note: The key can be removed from the steering lock only with the selector lever in position "P". With the key removed, the selector lever is locked in position "P".
R Reverse gear.
Shift to reverse gear only with the car stopped. N Neutral. No power is transmitted from the engine to the rear axle. When the brakes are released, the vehicle can be moved freely (pushed or towed). Do not engage "N" while driving except to coast when the vehicle is in danger of skidding (e.g. on icy roads, see page 19).
Important!
Coasting the vehicle for an ex­tended period of time with selector lever in "N" can result in transmission damage. That is not covered by the MERCEDES­BENZ Limited Warranty.
D The transmission automatically
upshifts to 5th gear. Position "D" provides optimum driving characteristics under all normal operating conditions.
4 Upshift to 4th gear only.
Suitable for performance driving.
3 Upshift to 3rd gear only. Suitable
for moderately steep hills. Since the transmission does not shift higher than 3rd gear, this gear selection will allow use of the engine's braking power downhill.
2 Upshift to 2nd gear only. For
driving in mountainous regions or under extreme operating conditions. This gear selection will allow use of the engine's braking power when descending steep grades.
Important!
With selector lever in position "D", "4" or "3", upshifting from 1st to 2nd to 3rd gear is delayed depending on vehicle speed and engine temperature. This allows the catalytic converter to heat up more quickly to operating temperatures.
During the brief warm-up period this delayed upshift and increased engine noise might be perceived as a malfunction. However, neither the engine nor transmission are negatively affected by this mode of operation.
78
Page 79
The delayed upshift is effective with vehicle speeds below 31 mph (50 km/h) at partial throttle and engine temperatures below 95°F (35°C).
To avoid over-revving the engine, the selector lever cannot be moved to a lower gear if the vehicle speed exceeds the speed limit of that gear.
Warning!
On slippery road surfaces, never downshift in order to obtain braking action. This could result in rear wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control.
To prevent the engine from laboring at low RPMs, do not allow the engine speed to drop too low on uphill gradients.
Depending on the degree of the incline, shift selector lever to a lower gear early enough to maintain engine RPM within the best torque range.
Maneuvering
To maneuver in tight areas, e.g. when pulling into parking space, control the car speed by gradually releasing the brakes. Accelerate gently and never abruptly step on the accelerator.
To rock a car out of soft ground (mud or snow), alternately shift from forward to reverse, while applying slight partial throttle. Rocking a car free in this manner may cause the ABS warning lamp to come on. Turn off and restart the engine to clear the malfunction indication.
Stopping
For brief stops, e.g. at traffic lights, leave the transmission in gear and hold vehicle with the service brake. For longer stops with the engine idling, shift into "N" or "P". When stopping the car on an uphill incline, do not hold it with the accelerator, use the brake. This avoids unnecessary transmission heat build up.
Warning!
Getting out of your car with the selector lever not fully engaged in position "P" is dangerous. When parked on a steep incline, position "P" alone may not prevent your vehicle from rolling, possibly hitting people or objects. Always set the parking brake in addition to shifting to position "P".
When parked on an incline, also turn front wheel against curb.

N Neutral.
No power is transmitted from the engine to the rear axle. When the brakes are released, the vehicle can be moved freely (pushed or towed). Do not engage "N" while driving except to coast when the vehicle is in danger of skidding (e.g. on icy roads, see Winter driving Instructions in Index).
Important!
Coasting the vehicle for an ex­tended period of time with selector lever in "N" can result in transmission damage. That is not covered by the MERCEDES­BENZ Limited Warranty.
D The transmission automatically
upshifts to 4th gear. Position "D" provides optimum driving characteristics under all normal operating conditions.
4 Upshift to 4th gear only. Suitable
for performance driving. To shift from position "D" to "4", push selector lever to the left.
3 Upshift to 3rd gear only. Suitable
for moderately steep hills. Since the transmission does not shift higher than 3rd gear, this gear selection will allow use of the engine's braking power downhill.
2 Upshift to 2nd gear only. For
driving in mountainous regions or under extreme operating conditions. This gear selection will allow use of the engine's braking power when descending steep grades.
1 In this position, the engine's
braking effect is utilized by shifting into 1st gear. Use this position while descending very steep or lengthy downgrades and only at speeds below 40 mph (60 km/h).
Important!
With selector lever in position "D", "4" or "3", upshifting from 1st to 2nd to 3rd gear is delayed depending on vehicle speed and engine temperature.

When stopping the car on an uphill incline, do not hold it with the accelerator, use the brake. This avoids unnecessary transmission heat build up.
Warning!
To avoid overrevving the engine when the selector lever is moved to a lower driving range, the transmission will not shift to a lower gear as long as the vehicle speed exceeds the speed limit of that gear.
To prevent the engine from laboring at low RPMs, do not allow the engine speed to drop too low on uphill gradients.
Depending on the degree of the incline, shift selector lever to a lower gear range early enough to maintain engine RPM within the best torque range.
To rock a car out of soft ground (mud or snow), alternately shift from forward to reverse, while applying slight partial throttle.
Rocking a car free in this manner may cause the ABS warning lamp to come on. Turn off and restart the engine to clear the malfunction indication.
Getting out of your car with the selector lever not fully engaged in position "P" is dangerous. When parked on a steep incline, position "P" alone may not prevent your vehicle from moving, possibly hitting people or objects. Always set the parking brake in addition to shifting to position "P". When parked on an incline, also turn front wheel against curb.

Press switch on symbol "S". Use this mode for all regular driving.
The vehicle starts out in 1st gear.
W Winter (snow and ice) mode
Press switch on symbol "W". The vehicle starts out in 2nd gear, except with selector lever in 1st gear, or with accelerator pedal in kick-down position.
Emergency Operation (Limp Home Mode)
If vehicle acceleration worsens, or the transmission no longer shifts, the transmission operates in Limp Home Mode. In addition the "CHECK ENGINE" malfunction indicator lamp in the instrument cluster may come on.
In this mode only the 2nd gear or reverse gear can be activated.
Program Mode Selector Switch
The transmission is provided with a selector switch for Standard "S" and Winter (snow and ice) "W" program modes.
Warning!
Always be certain of the program mode selected since the vehicle driving characteristics change with the selection of the program mode.
The "W" mode helps to improve traction and driving stability of the vehicle. With hard acceleration the upshifts occur at lower vehicle and engine speeds than in the "S" program mode.
Warning!
During stops use the brake, especially on an incline, to prevent the vehicle from rolling.
To engage 2nd gear or reverse:
1. Stop the vehicle.
2. Move selector lever to position "P".
3. Turn off the engine.
4. Wait 10 seconds.
5. Restart the engine.
6. Move selector lever to position "D" (for 2nd gear), or move selector lever to position "R" (for reverse gear).
Have the transmission checked at your authorized Mercedes-Benz dealer as soon as possible.

Cruise Control
speed.
Any given speed above approximately 25 mph (40 km/h) can be maintained with the cruise control by operating the lever.
1. Accelerate and set: Lift lever briefly to set speed. Hold lever up to accelerate.
2. Decelerate and set: Depress lever briefly to set Hold lever down to decelerate.
Normally the vehicle is accelerated to the desired speed with the accelerator.
Speed is set by briefly pushing the lever to position 1 or 2. The accelerator can be released.
The speed can be increased (e.g. for passing) by using the accelerator. As "soon as the accelerator is released, the previously set speed will be resumed automatically.
If a set speed is to be increased or decreased slightly, e.g. to adapt to the traffic flow, hold lever in position 1 or 2 until the desired speed is reached, or briefly tip the control lever in the appropriate direction for increases or decreases in 1 km/h (0.6 mph) increments. When the lever is released, the newly set speed remains.
3. Canceling To cancel the cruise control, briefly push lever to position 3.
When you step on the brake or clutch pedal or the vehicle speed drops below approx. 35 km/h (22 mph), for example when driving upgrade, the cruise control will be canceled. If the cruise control cancels by itself and remains inoperative until the engine is restarted, have the system checked at your authorized MERCEDES-BENZ dealer as soon as possible.
4. Resume If the lever is briefly pushed to position 4 when driving at a speed exceeding approx. 40 km/h (25 mph), the vehicle resumes the speed which was set prior to the cancellation of the cruise control. The last memorized speed is canceled when the key in the steering lock is turned to position 1 or 0.
83
Page 84
Note: If the engine does not brake the vehicle sufficiently while driving on a downgrade, the speed you set on the cruise control may be exceeded and you may have to step on the brake pedal to slow down. As soon as the grade eases, the cruise controlled speed will again be maintained as long as the brakes were not previously applied, or the lever may be used to resume the previously set speed if the brakes were applied.
Warning!
Only use the cruise control if the traffic and weather conditions make it advisable to travel at a steady speed.
The use of cruise control can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a steady speed.
The use of cruise control can be dangerous on slippery roads. Rapid changes in tire adhesion can result in wheel spin and loss of control.
The "Resume" function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed.
Caution!
When driving with the cruise control engaged, the transmission slector lever must not be shifted to position "N" as otherwise the engine will overrev, possibly causing engine damage that is not covered by the Mercedes-Benz Limited Warranty.

Charge Indicator Lamp
Should the charge indicator lamp fail to come on prior to starting when the key is in steering lock position 2 or should it fail to go out after starting or during operation, this indicates a fault which must be repaired at an authorized MERCEDES-BENZ dealer immediately.
If the charge indicator lamp comes on while the engine is running, this may indicate that the poly-V-belt has broken. Should this condition occur, the poly-V-belt must be replaced before continuing to operate the vehicle. Otherwise, the engine will overheat due to an inoperative water pump which may result in damage to the engine.
Do not continue to drive the vehicle with the charge indicator lamp illuminated. Doing so could result in engine damage that is not covered by the Mercedes-Benz Limited Warranty.
Engine Oil Pressure Gauge
The oil pressure at idle speed may drop if the engine is at operating temperature. This will not jeopardize the engine's operational reliability.
Pressure must, however, rise immediately upon acceleration.
Note: If the oil pressure gauge needle drops to "0" with the engine running, then damage to the engine may occur with continued operation. Turn off engine immediately and contact an authorized Mercedes-Benz dealer. Do not operate the car until the condition is repaired.
Low Engine Oil Level Warning Lamp
With the key in steering lock position 2, the oil pressure warning lamp comes on and goes out with the engine running.
If the warning lamp comes on with the engine running and at operating temperature, the engine oil level has
dropped to approximately the minimum mark on the dipstick. When this occurs, the warning lamp will first come on intermittently and then stay on if the oil level drops further.
If no oil leaks are noted and there is indicated engine oil pressure, continue to drive to the nearest service station where the engine oil should be topped to the "full" mark on the dipstick with an approved oil.
The low engine oil level warning light should not be ignored. Extended driving with the light illuminated could result in engine damage that is not covered by the Mercedes-Benz Limited Warranty.
In addition to the warning lamp, the engine oil level should be periodically checked with the dipstick, for example during a fuel stop, or before a long trip. See Index.

Engine Oil Consumption
Fuel Consumption Gauge
Tachometer
Engine oil consumption checks should only be made after the break-in period. During the break-in period, higher oil consumption may be noticed and is normal. Frequent driving at high engine speeds results in increased consumption.
While driving, instantaneous fuel consumption is indicated in miles per gallon (mpg), or in Canada liters per 100 kilometers (I/100 km).
With the engine switched off, the needle reads "0".
Due to system design, maximum consumption is indicated at idle speed.
Red marking on tachometer: Excessive engine speed. Avoid this engine speed, as it may result in engine damage that is not covered by the Mercedes-Benz Limited Warranty. For engine protection, the fuel supply is interrupted if the engine is operated within the red marking.

Fuel Reserve Warning Lamp
Warning!
Warning!
With the key in steering lock position 2, the fuel reserve warning lamp comes on and goes out with the engine running. If the warning lamp does not go out after starting the engine or if it comes on while driving, it indicates that the fuel level is down to the reserve quantity of approx. 2.6 gal (10 liters).
Outside Temperature Indicator
The temperature sensor is located in the front bumper area. Due to its location, the sensor can be affected by road or engine heat during idling or slow driving. This means that the accuracy of the displayed temperature can only be verified by comparison to a thermometer placed next to the sensor, not by comparison to external displays (e.g. bank signs, etc.). Adaptation to ambient temperature takes place in steps and depends on the prevailing driving conditions (stop-and­go or moderate, constant driving) and amount of temperature change.
The outside temperature indicator is not designed to serve as an Ice­Warning Device and is therefore un­suitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice.
Coolant Temperature Gauge
If the antifreeze mixture is effective to
-22°F (-30°C ), the boiling point of the
coolant in the pressurized cooling system of your vehicle is approx. 266°F (130°C). During severe operating conditions and stop-and-go city traffic, the coolant temperature may rise close to the red marking. The engine should not be operated with the coolant temperature in the red zone. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.
Driving when your engine is badly overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. Turn off the engine and get out of the car until it cools down.
Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Turn off the engine and do not stand near the car until it cools down.

Page 88
Low Engine Coolant Level Warning Lamp
With the key in steering lock position 2, the warning lamp comes on and goes out with the engine running.
If the warning lamp does not go out after starting the engine, or if it comes on while driving, then the coolant level has dropped below the required level. If no leaks are noticeable and the engine temperature does not increase, continue to drive to the nearest service station and have coolant added to the coolant system. (see Index).
The low engine coolant level warning light should not be ignored. Extended driving with the light illuminated may cause serious engine damage not covered by the Mercedes-Benz Limited Warranty.
In cases of major or frequent minor coolant loss, have the cooling system checked at your authorized MERCEDES-BENZ dealer as soon as possible.
Note: Do not drive without coolant in the cooling system. The engine can overheat causing major engine damage.
Monitor the coolant temperature gauge while driving.
Warning!
Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You can be seriously burned.
Low Windshield and Headlamp Washer Fluid Level Warning Lamp
With the key in steering lock position 2, the warning lamp comes on and goes out with the engine running.
If the warning lamp comes on with the engine running, the level of the reservoir has dropped to approx. 1/4 of the total volume. The reservoir should be refilled with MB Windshield Washer Concentrate "S" and water (or commercially available premixed windshield washer solvent/antifreeze, depending on ambient temperature ­see Index) at the next opportunity. The reservoir for the windshield and headlamp washer system is located in the engine compartment.
88
Page 89
Roll Bar Warning Lamp
With the key in steering lock position 2, the warning lamp comes on and goes out with the engine running.
Warning!
If the warning lamp does not go out after starting the engine, or if it comes on while driving, and the indicator lamps in the roll bar switch blink simultaneously, then the roll bar system is defective and may not activate in an accident. In this case, raise the roll bar manually (see Index) before continuing to drive.
Have the roll bar system checked at your authorized MERCEDES-BENZ dealer as soon as possible.
Seat Belt and Backrest Lock Warning Lamp
With the key in steering lock position 2, the warning lamp comes on and an audible warning sounds for a short time if the driver's seat belt is not fastened.
If a backrest is not engaged in its lock, an audible warning will sound intermittently for up to approx. 20 seconds.
After starting the engine, the warning lamp blinks for a brief period to remind the driver and passenger to fasten seat belts before driving off.
If the warning lamp does not go put after blinking briefly, but is instead lit continuously, then a backrest is not engaged in its lock.
The warning lamp goes out as soon as the backrest is engaged in its lock.
Exterior Lamp Failure Indicator Lamp
With the key in steering lock position 2, a dim indicator lamp comes on and goes out with the engine running.
With the key in steering lock position 2 or with the engine running, a bright illumination of this lamp indicates an exterior lamp failure (except high mounted stop lamp).
Note: The indicator lamp will also come on if an incorrect bulb is installed. If additional lighting equipment is installed (e.g. auxiliary headlamps etc.) be certain to connect into the fuse before the failure indicator monitoring unit in order to avoid damaging the system.
If an exterior lamp fails, the in­dicator lamp will come on only when that lamp is switched on.
If the backrest is locked and the warning lamp does not go out, have the system checked at your authorized MERCEDES-BENZ dealer as soon as possible.
If a brake or turn signal lamp fails, the lamp failure indicator will come on when applying the brake or actuating the turn signal and stay on until the engine is turned off.

Brake Pad Wear Indicator Lamp
Brake Warning Lamp
Warning!
The brake pad wear indicator lamp in the instrument cluster comes on when the key in the steering lock is turned to position 2 and goes out when the engine is running.
If the indicator lamp lights up during braking, this indicates that the front wheel brake pads are worn down (vehicles equipped with ASR front and/or rear wheel brake pads).
Have the brake system checked at your authorized MERCEDES-BENZ dealer as soon as possible.
The brake warning lamp will come on:
when there is insufficient brake fluid in the reservoir (engine running and parking brake released)
when the parking brake is set (engine running)
When the minimum mark on the reservoir is reached, have the brake system checked for brake pad thickness and leaks.
To test the brake warning lamp, turn the key in steering lock to position 2. The brake warning lamp comes on, and should go out when the engine is running.
Driving with the brake warning lamp on can result in an accident. Have your brake system checked immediately if the brake warning lamp stays on. Don't add brake fluid before checking the brake system. Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You can be seriously burned.

Antilock Brake System (ABS)
Important!
The ABS improves steering control of the vehicle during braking maneuvers. For maximum benefit, do not pump the brake pedal, rather use firm, steady brake pedal pressure.
The ABS prevents the wheels from locking up above a vehicle speed of approximately 5 mph (8 km/h) independent of road surface conditions.
At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal, indicating that the ABS is in the regulating mode.
On slippery road surfaces, the ABS will respond even with only slight brake pedal pressure. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.
The ABS warning lamp in the instrument cluster comes on with the key in steering lock position 2 and should go out with the engine running.
If the charging voltage falls below 10 volts, the warning lamp comes on and the ABS is switched off. When the voltage is above this value again, the warning lamp should go out and the ABS will be operational.
If the ABS warning lamp does not go out or comes on while driving, it indicates that the ABS has detected a malfunction and has switched off. In this case, the brake system functions in the usual manner, but without antilock assistance.
Have the system checked at your authorized MERCEDES-BENZ dealer as soon as possible.
Warning!
Even the ABS cannot prevent the natural laws of physics from acting on the vehicle. The ABS cannot prevent accidents, including those resulting from excessive speed in turns, following another vehicle too closely, or aquaplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ABS equipped car must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others.
Notes:
To alert following vehicles to slippery road conditions you discover, operate your hazard warning flashers as appropriate.
With the ABS malfunctioning, the ETS, ASR or ESP are also switched off. Both malfunction indicator lamps come on with the key in steering lock position 2.
91
Page 92
Electronic Traction System (ETS)
The ETS improves vehicle traction, especially under slippery road conditions. It engages at vehicle speeds up to approximately 24 mph (40 km/h), and applies the brakes to the spinning drive wheel. At approximately 50 mph (80 km/h), the ETS switches off.
With the key in steering lock position 2, the yellow ETS malfunction indicator lamp in the instrument cluster and the ETS warning lamp in the speedometer dial come on. They must go out when the engine is running.
If the ETS malfunction indicator lamp comes on with the engine running, a malfunction has been detected.
Caution!
If the vehicle is towed with the front axle raised (see Towing the vehicle in Index), or when testing the parking brake on a brake test dynamometer, the engine must be shut off. Otherwise, the electronic traction system will immediately be engaged and will apply the rear wheel brakes.
The ETS warning lamp, located in the speedometer dial, starts to flash at any vehicle speed, as soon as the tires lose traction and the wheels begin to spin.
Important!
If the ETS warning lamp flashes:
during take-off, apply as little throttle as possible,
while driving, ease up on the accelerator.
Adapt your speed and driving to the prevailing road conditions.
Have the ETS checked at your authorized Mercedes-Benz dealer as soon as possible.
With the ABS malfunctioning, the ETS is also switched off.
Notes: If the ETS malfunction indicator lamp comes on while the ETS warning lamp flashes, the electronic traction system is being switched off temporarily to prevent overheating of the drive wheel brakes.
In winter operation, the maximum effectiveness of the electronic traction system is only achieved with Mercedes-Benz recommended M + S radial-ply tires and/or snow chains.
92
Page 93
Acceleration Slip Regulation (ASR)
The acceleration slip regulation will engage at all vehicle speeds, if one or both drive wheels begin to lose traction and spin due to excessive acceleration. While engaged, the yellow warning lamp in the speedometer flashes.
With the acceleration slip regulation engaged, the brake is applied to the spinning drive wheel until it regains sufficient traction. If both drive wheels lose traction and spin, the brake is applied to both drive wheels and simultaneously, engine torque is limited, to improve the vehicle's driving stability.
As traction on the road surface increases, the allowable engine torque also increases again and the brake is no longer applied to drive wheels.
Important!
If the ASR warning lamp flashes, adapt your speed and driving to the prevailing road conditions.
Caution!
If the vehicle is towed with the front axle raised (see Towing the vehicle in Index), the engine must be shut off. Otherwise, the acceleration slip regulation will immediately be engaged and will apply the rear wheel brakes.
Notes: With the key in steering lock position 2, the yellow malfunction indicator lamp in the instrument cluster and the yellow ASR warning lamp in the speedometer dial come on. They must go out when the engine is running.
If the ASR malfunction indicator lamp comes on with the engine running, a malfunction has been detected. Pressing the accelerator pedal will require greater effort. Only partial engine output is available.
Have the ASR checked at your authorized Mercedes-Benz dealer as soon as possible.
With the ABS malfunctioning, the ASR is also switched off. Driving the vehicle with varied size tires will cause the wheels to rotate at different speeds, therefore the acceleration slip regulation may activate (yellow ASR malfunction indicator lamp in instrument cluster comes on). For this reason, all wheels, including the spare wheel, must have the same tire size.
When testing the parking brake on a brake test dynamometer, the engine must be shut off. Otherwise, the acceleration slip regulation will immediately be engaged and will apply the rear wheel brakes.
In winter operation, the maximum effectiveness of the acceleration slip regulation is only achieved with Mercedes-Benz recommended M + S radial-ply tires and/or snow chains.

The ASR warning lamp, located in the speedometer dial, starts to flash at any vehicle speed as soon as the tires lose traction and the wheels begin to spin. To switch off: press lower half of the switch (the ASR warning lamp in the speedometer dial goes out).
Important!
ASR control switch located in center console
With the ASR system switched off, the engine torque reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ASR is unavailable.
Adapt your speed and driving to the prevailing road conditions. A portion of the ASR system remains active, even with the switch in the OFF position.
If one drive wheel loses traction and begins to spin, the brake is applied until the wheel regains sufficient traction. The traction control engages at vehicle speeds up to approximately 24 mph (40 km/h), and switches off at 50 mph (80 km/h).
If the ASR warning lamp flashes:
during take-off, apply as little throttle as possible,
while driving, ease up on the accelerator.

Page 95
Electronic Stability Program (ESP)
The ESP enhances directional control and improves traction of the vehicle under any driving condition.
Over/understeering of the vehicle is counteracted by applying brakes to the left or right side wheels. The ESP warning lamp, located in the speedometer dial, starts to flash.
Important!
If the ESP warning lamp flashes, adapt your speed and driving to the prevailing road conditions.
Caution!
If the vehicle is towed with the front axle raised (see Towing the vehicle in Index), the key must not be in steering lock position 2. Otherwise, the electronic stability program will immediately be engaged and will apply the rear wheel brakes.
Notes:
With the key in steering lock position 2, the yellow ESP and EPC malfunction indicator lamps in the instrument cluster and the yellow warning lamp in the speedometer dial come on. They must go out when the engine is running.
If the ESP or EPC malfunction indicator lamp comes on with the engine running, a malfunction has been detected. It is possible that now only partial engine output is available.
Have the ESP checked at your authorized Mercedes-Benz dealer as soon as possible.
With the ABS malfunctioning, the ESP is also switched off.
Driving the vehicle with varied size tires will cause the wheels to rotate at different speeds, therefore the electronic stability program may activate (yellow ESP malfunction indicator lamp in instrument cluster comes on). For this reason, all wheels, including the spare wheel, must have the same tire size.
When testing the parking brake on a brake test dynamometer, the engine must be shut off. Otherwise, the electronic stability program will immediately be engaged and will apply the rear wheel brakes.

Emission Control
Warning!
On-Board Diagnostic System
Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits required by law.
These systems, of course, will function properly only when maintained strictly according to factory specifications. Any adjustments on the engine should, therefore, be carried out only by qualified MERCEDES-BENZ technicians. Engine adjustments should not be altered in any way. Moreover, the specified service and maintenance jobs must be carried out regularly according to MERCEDES-BENZ servicing requirements. For details refer to the Maintenance Booklet.
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause unconsciousness and lead to death. Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected im­mediately. If you must drive under these conditions, drive only with at least one window fully open.
The Sequential Multiport Fuel Injection (SFI) control module monitors emission control components that either provide input signals to or receive output signals from the control module. Malfunctions resulting from interruptions or failure of any of these components are indicated by the "CHECK ENGINE" malfunction indicator lamp in the instrument cluster and are simultaneously stored in the SFI control module.
If the "CHECK ENGINE" malfunction indicator lamp comes on, have the system checked at your authorized Mercedes-Benz dealer as soon as possible.
An on-board diagnostic connector allows the accurate identification of system malfunctions through the readout of diagnostic trouble codes.
Connector location:
SL 320 - passenger compartment, near the accelerator pedal. SL 500, SL 600 ­engine compartment, on firewall.
