1999 Mercedes-benz C280 Owners Manual

Drive Sensibly - Save Fuel

Fuel consumption, to a great extent, depends on driving habits and operating conditions. To save fuel you should: • keep tires at the recommended inflation pressures, • remove unnecessary loads, • remove roof rack when not in use, • allow engine to warm up under low load use, • avoid frequent acceleration and deceleration, • have all maintenance work performed at regular intervals by an authorized Mercedes-Benz dealer.

Fuel consumption is also increased by driving in cold weather, in stop-and-go traffic, on short trips and in hilly country.

Catalytic Converter Your Mercedes-Benz is equipped with monolithic type catalytic converters, an important element in conjunction with the oxygen sensors 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 Service Booklet.

Caution! 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, which could start a fire.

Warning! 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 and cause a vehicle fire.

Starting and Turning Off the Engine

Before Starting Ensure that parking brake is engaged and that selector lever is in position "P" or "N". Turn electronic key in steering lock to position 2. The charge indicator lamp should come on.

Starting (Model C 230) Do not depress accelerator. Turn electronic key in steering lock clockwise to the stop. Release electronic key only when the engine is firing regularly.

Starting (Models C 280, C 43 AMG) Do not depress accelerator. Briefly turn electronic key in steering lock clockwise to the stop and release. The starter will engage until the engine is running. If engine will not run, and the starting procedure stops, turn electronic key completely to the left and repeat starting the engine. After several unsuccessful attempts, have the system checked at the nearest authorized Mercedes-Benz dealer.

Important! Due to the installed starter non- repeat feature, the electronic key must be turned completely to the left before attempting to start the engine again. 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.

Turning Off

Turn the electronic key in the steering lock to position 0 to stop the engine. The electronic key can only be removed with your foot off the brake pedal and the selector lever in position "P".

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 service.

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. All checks and maintenance work on the brake system should be carried out by an authorized Mercedes-Benz dealer. 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. This could result in an accident.

Caution ! When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear. 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 approximately1/16 in (1.5 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. As tread depth approaches 1/16 in (1.5 mm), 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. Reduce vehicle speed, avoid track grooves in the road and apply brakes cautiously in the rain.

Tire Traction 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 whenever the outside temperatures areclose 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.

Tire Speed Rating Model C 36 AMG only: This vehicle is factory equipped with "Z"-rated tires. All other models: Your vehicle is factory equipped with "H"-rated tires, which have a European speed rating of 130 mph (210 km/h). An electronic speed limiter prevents your vehicle from exceeding the speed rating. 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.

Parking

Warning ! To reduce the risk of personal injury as a result of vehicle movement, before turning off the engine and leaving the vehicle always: 1. Keep right foot on brake pedal 2. Firmly depress parking brake pedal. 3. Move the selector lever to position "P". 4. Slowly release brake pedal. 5. Turn front wheels towards the road curb. 6. Turn the key to steering lock position 0 and remove.

7. Take your key and lock vehicle when leaving

Important ! It is advisable to set the parking brake whenever parking or leaving the vehicle. In addition, move selector lever to position "P". When parking on hills, always set the parking brake.

Winter Driving Instructions The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, 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 travelling 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.

Deep Water Caution ! Do not drive through flooded areas or water of unknown depth. If you must drive through deep water, drive slowly to prevent water from entering the engine compartment or being ingested by the air intake, possibly causing damage to electrical components or wiring, to engine or transmission that is not covered by the Mercedes-Benz Limited Warranty.

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.

Automatic Climate Control

The system is always at operational readiness, except when manually switched off. The automatic climate control only operates with the engine running. The temperature selector should be left at the desired temperature setting. The temperature selected is reached as quickly as possible. The system will not heat or cool any quicker by setting a higher or lower temperature.

Warning ! When leaving the vehicle always remove the electronic key from the steering lock. The power seats can also be operated with the driver's or passenger door open. Do not leave children unattended in the vehicle or with access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause serious personal injury.

Caution ! Do not remove head restraints except when mounting seat covers. For removal refer to Head Restraints, Front, see Index. Whenever restraints have been removed be sure to reinstall them before driving.

Important ! Prior to operating the vehicle, the driver should adjust the seat height for proper vision as well as fore/aft placement and seat back angle to insure adequate control, reach, operation, and comfort. The head restraint should also be adjusted for proper height. See also airbag section for proper seat positioning. Both the inside and outside rear view mirrors should be adjusted for adequate rearward vision. Fasten seat belts. Infants and small children should be seated in a properly secured restraint system that complies with U.S. Federal Motor Vehicle Safety Standard 213 and Canadian Motor Vehicle Safety Standard 213.1. All seat, head restraint, and rear view mirror adjustments as well as fastening of seat belts should be done before the vehicle is put into motion.

Warning ! Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the passenger side airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. The back seat is the safest place for children. Infants and small children must ride in the back seats and be seated in an appropriate infant or child restraint system, which is properly secured with the vehicle's seat belt, fully in accordance with the seat manufacturer's instructions. A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint.

Important ! For safety reasons, always drive with the rear head restraints in the upright position when the rear seats are occupied. Keep area around head restraints clear of articles (e.g. clothing) to not obstruct the folding operation of the head restraints.

Seat Belts Your vehicle is equipped with seat belts for all seats, emergency tensioning retractors for the front seats, as well as front and side impact airbags and knee bolsters for driver and front passenger.

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. For your safety and that of your passengers we strongly recommend their use.

Warning !

Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart? compatible child seat, which operates with the BabySmart? system installed in the vehicle to deactivate the passenger side front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. The back seat is the safest place for children. Infants and small children must ride in back seats and be seated in an appropriate infant or child restraint system, which is properly secured with the vehicle's seat belt, fully in accordance with the seat manufacturer's instructions. A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint.

Warning !

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.

Seat Belt Warning System With the electronic key in steering lock position 2, a 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 are much more likely to 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.

Fastening of Seat Belts

1. Latch plate 2. Buckle 3. Release button 4. Button for belt outlet eight adjustment

Push latch plate (1) into buckle (2) until it clicks. Do not twist the belt. A twisted seat belt may cause injury. The lap belt should be positioned as low as possible on your hips and not across the abdomen. Tighten the lap portion to a snug fit by pulling shoulder portion up. The shoulder portion of the seat belt must be pulled snug and checked for snugness immediately after engaging it. Adjust seat belt so that shoulder portion is located as close as possible to the middle of your shoulder (it should not touch the neck). For this purpose, you can adjust the height of the belt outlet. Three positions are available

Raising: Slide belt outlet upward. Lowering: Press button (4) and slide belt outlet downward.

Caution ! For safety reasons, avoid adjusting the seat or seat back into positions which could affect the correct seat belt position.

Lap Belt for Center Seating Position of the Rear Seat Pull belt with latch plate (1) over lap so that the belt is positioned as low as possible on your hips and not across the abdomen. Push latch plate (1) into buckle (2) until it clicks. Do not twist the belt but keep it tight. To tighten the belt: With the latch plate engaged, pull the loose end of the belt. To lengthen the belt: With the belt unfastened, turn the latch plate so that it is a little more than 90° perpendicular to the belt, then extend the belt. Fasten the belt and tighten as stated above. To disengage the belt, push red button (3) in the buckle. If the center seat is not occupied, the belt buckle and rolled- up seat belt can be stored in the space next to the rear armrest (to the left or right of armrest). Note: For cleaning and care of the seat belts, see Cleaning and Care of the Vehicle in Index.

Unfastening of Seat Belts Push the release 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 out the belt.

Warning !

USE SEAT BELTS PROPERLY. • Each occupant should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, including rollovers. "SRS" (driver airbag, front passenger airbag, front door side impact airbags), "ETR" (seat belt emergency tensioning retractors), and knee bolsters are impacts which exceed preset deployment thresholds. • Improperly positioned seat belts do not provide maximum protection and may cause serious injuries in case of an accident. • Never wear the shoulder belt under your arm, against your neck or off your shoulder. In a crash, your body would move too far forward. That would increase the chance of head and neck injuries. The belt would also apply too much force to the ribs or abdomen, which could severely injure infernal organs such as your liver or spleen.

• 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. • Each seat belt should never 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 manage 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.

Warning !

USE CHILD RESTRAINTS PROPERLY. Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized Baby Smart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the passenger side front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. The back seat is the safest place for children. Infants and small children must ride in back seats and be seated in an appropriate infant or child restraint system, which is properly secured with the vehicle's seat belt, fully in accordance with the seat manufacturer's instructions. A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint. Children too big for child restraint systems must ride in back seats using 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.

BabySmart™ Airbag Deactivation System

Special child seats, designed for use with the Mercedes-Benz system and available at any authorized Mercedes-Benz dealer are required for use with the BabySmart™ airbag deactivation system. With the special child seat properly installed, the passenger front airbag will not deploy. The

indicator lamp located on the center console will be illuminated, except with electronic key removed or in steering lock position 0. The system does not deactivate the door mounted side impact airbag.

Warning !

The BabySmart™ Airbag Deactivation System will ONLY work with a special seat designed to operate with it. It will not work with seats which are not BabySmart™ compatible. Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the deactivation system. Follow the manufacturer's instructions for installation of special indicator lamp child seats. The passenger side front airbag will not deploy only if the remains illuminated. Please be sure to check the indicator every time you use the special system child seat. Should the light go out while the restraint is installed, please check installation. If the light remains out, do not use the BabySmart™ restraint to transport children, or otherwise do not transport child restraints on the front passenger seat until the system has been repaired.

Self-Test BabySmart™ Without Special Child Seat Installed After turning electronic key in steering lock to position 1 or 2, the center console comes on for approx. 6 seconds. If the lamp should not come on or is continuously lit, the system is not functioning. You must see an authorized Mercedes-Benz dealer before using any child seat.

Supplemental Restraint System (SRS)

The term Supplemental Restraint System means that airbags are intended as a supplement to seat belts. Airbags alone cannot protect as well as airbags plus seat belts in impacts for which the airbags were designed to operate, and do not afford any protection whatsoever in crashes for which the system is not designed to deploy. 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.

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.

Emergency Tensioning Retractor (ETR)

The seat belts for the front seats are equipped with emergency tensioning retractors. These tensioning retractors are located in each belt's inertia reel and become operationally ready with the electronic key in steering lock position 1 or 2. The emergency tensioning retractors are designed to activate only when the seat belts are fastened during frontal impacts exceeding the first threshold of the SRS and in rear impacts exceeding a preset security level. 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. In cases of other frontal impacts, angled impacts, roll-overs, certain side impacts, or other accidents without sufficient frontal or rear impact forces, the emergency tensioning retractors will not be activated. The driver and passengers will then be protected by the fastened seat belts and inertia reel in the usual manner. For seat belt and emergency tensioning retractor safety guidelines see Safety Guidelines in Index.

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 front 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 or rear impacts (for front airbags) and side impacts (for side impact airbags). 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 coming on again. The following system components are monitored or undergo a self-check: crash-sensor(s), airbag ignition circuits, front seat belt buckles, emergency tensioning retractors, seat sensor (when present). Initially, when the electronic 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 or short circuits in the airbag ignition circuit and in the driver and passenger seat belt buckle harnesses, and low voltage in the entire system are detected and indicated.

Warning ! In the event a malfunction of the "SRS" is indicated as outlined above, the "SRS" may not be operational. For your safety, 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 in an accident, which could result in serious or fatal injury, or it might deploy unexpectedly and unneccesarily which could also result in injury.

Front Airbags The driver and passenger front "SRS" airbags are designed to activate only in certain frontal or rear impacts. The front passenger airbag deploys only if the passenger seat is occupied.

Note: Heavy objects on passenger seat can cause the front airbag to deploy in a crash.

Side Impact Airbags The side impact "SRS" airbags are designed to activate only in certain side impacts. Only the side airbag on the impacted side of the vehicle deploys. The side impact airbag for the front passenger deploys only if the seat is occupied. Side impact airbags operate best in conjunction with a properly positioned and fastened seat belt. Note: Heavy objects on passenger seat can cause the side impact airbag to deploy in a crash

Important ! The "SRS" airbags are designed to activate only in certain frontal or rear (front airbags) impacts, or side (side airbags) impacts. Only during these types of impacts, if of sufficient severity to meet the deployment thresholds, 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, angled impacts, roll-overs, other side impacts, rear collisions, or other accidents without sufficient forces, the airbag will not be activated. The driver and passengers 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. The "SRS" is designed to reduce the potential of injury in certain frontal and rear (front airbags) impacts, and side (side airbags) impacts which may cause significant 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 airbags. 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 driverside 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.

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 and hands on steering wheel position will help to keep you in a safe distance from the airbag: • Sit properly belted in an upright position with your back against the seat back. • Adjust the driver seat as far as possible rearward, still permitting proper operation of vehicle controls. • Do not lean with your head or chest close to the steering wheel or dashboard. • Keep hands on the outside of steering wheel rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when airbag inflates. • Adjust the front passenger seat rearward as far as possible from the dashboard when the seat is occupied. • Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the passenger side front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. Failure to follow these instructions can result in severe injuries to you or other occupants.

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, front passenger airbag cover, or front door trim panels, and installation of additional electrical/electronic equipment on or near "SRS" components and wiring. • An airbag system component within the steering wheel gets hot after the airbag has inflated. • 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 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.

Infant and Child Restraint Systems

We recommend that all infants and children be properly restrained at all times while the vehicle is in motion. All lap- shoulder belts except driver seat have special seat belt retractors for secure fastening of child restraints. To fasten a child restraint, use this seat belt: Follow child restraint instructions for routing. Then pull shoulder belt out completely and let it retract. The belt 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 appropriate infant or child restraint system properly secured by a lap-shoulder belt, and that complies with U.S. Federal Motor Vehicle 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. Please read and observe warning labels affixed to inside of vehicle.

Warning ! Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the passenger side front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. The back seat is the safest place for children, infants and small children must ride in back seats and be seated in an infant or child restraint system, which is properly secured with the vehicle's seat belt, fully in accordance with the seat manufacturer's instructions. 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 must ride in back seats using regular seat belts. Position shoulder belt across chest and shoulder, not face or neck. A booster seat is necessary to achieve proper belt positioning for children from 41 Ibs. to the point where a lap/shoulder belt fits properly without one. 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 is provided with tether anchorages for a top tether strap. Consult your authorized Mercedes-Benz dealer for installation of these anchorages. In compliance with Canadian Motor Vehicle Safety Standard 210.1, child restraint tether anchorage hardware is attached to the tool kit located in the trunk.

Enlarged Cargo Area. Split Folding Rear Seat Backrest

On vehicles with optional split folding rear seat backrest you can fold down the two sections separately to enlarge the cargo area.

Fold down: Pull locking handle and fold backrest forward. Set up: Pull backrest up until it locks in its upright position. Check for secure locking by pushing and pulling on the backrest.

Warning ! Always lock backrest in its upright position when rear seat bench is occupied by passengers, cargo is being carried in the trunk, or the extended cargo area is not in use.

Note: To prevent unauthorized persons from access to the trunk, always lock backrest in its upright position.

Loading instructions (Vehicles with enlarged cargo area)

The total load weight including vehicle occupants and luggage/ cargo should not exceed the vehicle capacity weight indicated on the certification tag which can be found on the left door pillar. The handling characteristics of a fully loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle according to the illustrations shown, with the heaviest items being placed towards the front of the vehicle. Always place items being carried against front or rear seat backrests, and fasten them as securely as possible. The heaviest portion of the cargo should always be kept as low as possible since it influences the handling characteristics of the vehicle.

Notes: The trunk is the preferred place to carry objects. The enlarged cargo area should only be used for items which do not fit in the trunk alone.

Warning ! In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle. To help avoid personal injury during a collision or sudden maneuver, exercise care when stowing things. Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backs. Do not place anything on the shelf below the rear window. Never drive vehicle with trunk lid open while pass-through is not closed and seat backrest not locked in its upright position. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

Cargo Tie-Down Rings (Vehicles with enlarged cargo area)

1. Ring Carefully secure cargo by applying even load on all four rings with rope of sufficient strength to hold down the cargo.

Shelf below Rear Window

Warning! The shelf below the rear window should not be used to carry objects. This will avoid such objects from being thrown about and injuring vehicle occupants during an accident or sudden maneuver.
