2001 Mercedes-benz C Class Owners Manual

Control and operation of radio transmitters COMAND, radio, telephone and two-way radio

Telephones and two-way radio

Warning! Please do not forget that your primary responsibility is to drive the vehicle. Only operate the COMAND (Cockpit Management and Data System), radio, telephone1 or two-way radio1 if road and traffic conditions permit. Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of approximately 50 feet (approximately 14 m) every second.

Warning! Never operate radio transmitters equipped with a built-in or attached antenna (i.e. without being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunction of the vehicle’s electronic system, possibly resulting in an accident and personal injury.

Radio transmitters, such as a portable telephone or a citizens band unit should only be used inside the vehicle if they are connected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation instructions regarding use of an external antenna.

1 Observe all legal requirements.

The first 1 000 miles (1 500 km) 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 1 000 miles (1 500 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 that you select positions “3”, “2” or “1” only at moderate speeds (for hill driving). After 1 000 miles (1 500 km) speeds may be gradually increased to the permissible maximum.

Maintenance Approximately 30 days or 2000 miles (2000 km) prior to the next recommended service, the remaining distance or days are displayed in the multifunction indicator. See Flexible service system (FSS) on page 125. We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz Center, in accordance with the Service Booklet at the times called for by the FSS. Failure to have the vehicle maintained in accordance with the Service Booklet at the designated times/ mileage may result in vehicle damage not covered by the Mercedes-Benz Limited Warranty.

Tele Aid

Important! The initial activation of the Tele Aid system may only be performed by completing the subscriber agreement and placing an acquaintance call using the “SOS” button. Failure to complete either of these steps will result in a system that is not activated. If you have any questions regarding activation, please call the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada).

(Telematic Alarm Identification on Demand) The Tele Aid system consists of three types of response; automatic and manual emergency, roadside assistance and information. The Tele Aid system is always operational, providing that the vehicle’s battery is charged and properly connected. To activate, press the “SOS” button, the Roadside Assistance button (cid:127) or the Information button ¡, depending on the type of response required.

System self-check Initially, after turning the electronic key in starter switch to position 2, malfunctions are detected and indicated (the indicator lamps in the “SOS” button, the Roadside Assistance button (cid:127) and the Information button ¡ stay on longer than 5 seconds or do not come on). If a malfunction is indicated as outlined above, have the system checked at the nearest Mercedes-Benz Center as soon as possible.

Important! Always make sure that the indicator lamp in the “SOS” button remains illuminated for approximately 5 seconds during the system self-check after turning electronic key in starter switch to position 2.

Emergency calls An emergency call is initiated automatically following an accident in which the Emergency Tensioning Retractors (ETR’s) or airbags deploy. An emergency call can also be initiated manually by opening the cover next to the inside rear view mirror labeled “SOS”, then

pressing the button (for longer than 2 seconds) located under the cover. See below for instructions on initiating an emergency call manually. Once the emergency call is in progress, the indicator lamp in the “SOS” button will begin to flash. The message “EMERGENCY CALL – ESTABLISHING CALL” appears in the multifunction display. When the connection is established, the message “EMERGENCY CALL – CALL CONNECTED” appears in the multifunction display. All information relevant to the emergency, such as the location of the vehicle (determined by the GPS satellite location system), vehicle model, identification number and color are generated. A voice connection between the Response Center and the occupants of the vehicle will be established automatically soon after the emergency call has been initiated. The Response Center will attempt to determine more precisely the nature of the accident provided they can speak to an occupant of the vehicle.

The Tele Aid system is available if: • it has been activated and is operational. Activation requires a subscription for monitoring services and cellular air time,

• the relevant cellular phone network and GPS signals

are available.

Note: Location of the vehicle on a map is possible if the vehicle is able to receive signals from the GPS satellite network.

Warning! If the indicator lamp in the “SOS” button is illuminated continuously and there was no voice connection to the Response Center established, then the Tele Aid system could not initiate an emergency call (e.g. the relevant cellular phone network is not available). The message “EMERGENCY CALL – CALL FAILED” appears in the multifunction display. Should this occur, assistance must be summoned by other means.

Initiating an emergency call

Manually: Briefly press on cover (1) – the cover will open.

Press the emergency call switch (2) briefly (for longer than 2 seconds). The indicator lamp in the emergency call switch (2) will flash until the emergency call is concluded. Wait for a voice connection to the Response Center. Close the cover (1) after the emergency call is concluded.

Warning! If you feel at any way in jeopardy when in the vehicle (e.g. smoke or fire in the vehicle, vehicle in a dangerous road location), please do not wait for voice contact after you have pressed the emergency button. Carefully leave the vehicle and move to a safe location. The Response Center will automatically contact local emergency officials with the vehicle’s approximate location if they receive an “SOS” signal and cannot make voice contact with the vehicle occupants.

Roadside Assistance button (cid:127) Located below the center armrest cover is the Roadside Assistance button (cid:127). Pressing and holding the button (for longer than 2 seconds) will initiate a call to a Mercedes-Benz Roadside Assistance dispatcher. The button will flash while the call is in progress. The Tele Aid system will transmit data generating the vehicle identification number, model, color and location (subject to availability of cellular and GPS signals).

A voice connection between the Roadside Assistance dispatcher and the occupants of the vehicle will be established. The nature of the need for assistance can then be described. Sign and Drive services (jump start, a few gallons of fuel or the replacement of a flat tire with the vehicle spare tire) are available. If the vehicle requires more than Sign and Drive services, the Mercedes-Benz Roadside assistance dispatcher will either dispatch a qualified Mercedes-Benz technician or arrange to tow your vehicle to the nearest Mercedes-Benz Center. For other than Sign and Drive services, labor and/or towing charges may apply. Refer to the Roadside Assistance manual for more information.

Notes: The indicator lamp in the Roadside Assistance button (cid:127) remains illuminated in red for approximately 5 seconds during the system self-check after turning electronic key in starter switch to position 2 (together with the “SOS” button and the Information button ¡). See system self-check on page 220 when the indicator lamp does not light up in red or stays on longer than approximately 5 seconds.

See system self-check on page 220 when the indicator lamp does not light up in red or stays on longer than approximately 5 seconds.

Important! If the indicator lamps do not illuminate or remain illuminated (in red) at any time, the Tele Aid system has detected a fault or the service is not currently active, and may not initiate a call. Visit your Mercedes-Benz Center and have the system checked or contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada) as soon as possible.

Upgrade Signals Tele Aid system processes calls using the following priority. • Automatic emergency – First priority • Manual emergency – Second priority • Roadside assistance – Third priority • Information – Fourth priority Should a higher priority call be initiated while you are connected, an upgrade (alternating) tone will be heard, and the appropriate indicator lamp will flash. If certain information such as vehicle identification number or client information is not available, the operator may need to retransmit. During this time you will hear a chirp and voice contact will be interrupted. Voice contact will resume once the retransmission is complete. Once a call is concluded, a chirp will be heard, the appropriate indicator lamp will stop flashing and a tone will be heard indicating that the system has reset.

Important! If the indicator lamp continues to flash or the system does not reset, contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada), or Mercedes-Benz Client Assistance at 1-800-FOR-MERCedes (1-800-367-6372) in the USA or Customer Service at 1-800-387-0100 in Canada.

Catalytic converter

228

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.

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.

Emission control 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 Center authorized technicians. Engine adjustments should not be altered in any way. Moreover, the specified service jobs must be carried out regularly according to Mercedes-Benz servicing requirements. For details refer to the Service Booklet.

Warning! 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.

key or with the electronic key in starter switch position 0, the selector lever is locked in position “P”.

1 Gear selector lever is unlocked.

Most electrical consumers can be operated. For detailed information see respective subjects.

2 Driving position. 3 Starting position.

See page 232 for instructions on starting and stopping the engine.

Warning! When leaving the vehicle always remove the electronic key from the starter switch, and lock the vehicle. 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.

Important! If the electronic key is left in the starter switch position 0 for a extended period of time, it can no longer be turned in the lock. In this case, remove electronic key from starter switch and reinsert.

Caution! To prevent accelerated battery discharge and a possible dead battery, always remove the electronic key from the starter switch. Do not leave the electronic key in starter switch position 0.

Notes: A warning sounds when the driver’s door is opened with the electronic key is in starter switch position 1 or 0. With the engine at idle speed, the charging rate of the alternator (output) is limited. It is therefore recommended that you turn off unnecessary electrical consumers while driving in stop- and-go traffic. This precaution helps to avoid draining of the battery. Unnecessary strain on the battery and charging system may be minimized by turning off the following power consumers, for example: Heated seats, rear window defroster. In addition, the automatic climate air volume control should be set to the lowest position.

Starting and turning off the engine

Before starting Ensure that parking brake is engaged and that selector lever is in position “P” or “N” (gearshift lever in neutral). Turn electronic key in starter switch to position 2.

Starting

Vehicles with automatic transmission: Do not depress accelerator. Briefly turn electronic key in starter switch 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 Center.

Vehicles with manual transmission: Do not depress accelerator. Fully depress clutch pedal, otherwise the engine cannot be started due to the integrated safety interlock. Turn electronic key in starter switch clockwise to the stop. Release only when the engine is firing regularly.

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. In areas where temperatures frequently drop below -4°F (-20°C) we recommend that an engine block heater be installed. Your authorized Mercedes-Benz Center will advise you on this subject, see page 251.

Turning off Turn the electronic key in the starter switch to position 0 to stop the engine.

Vehicles with automatic transmission: The electronic key can only be removed with the selector lever in position “P”.

Manual transmission

See illustration for gearshift lever positions corresponding to the individual gears.

Manual transmission

233

Stop the vehicle completely before shifting into reverse; to shift into reverse, pull the gearshift lever up. Do not exceed the maximum engine speed in the individual gears. Refer to tachometer (see page 91) for engine speeds.

Important! When vehicle is parked, always be sure to engage first or reverse gear and firmly set parking brake. When parked on an incline, also turn front wheel towards the road curb. Downshifting gears leading to overrevving the engine can result in transmission damage that is not covered by the Mercedes-Benz Limited Warranty. Do not exceed engine speed limits, see page 91.

Warning! On slippery road surfaces as well as high engine speeds, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle’s ABS will not prevent this type of loss of control.

Automatic transmission

The automatic transmission selects individual gears automatically, dependent upon • Selector lever position • Program mode selector • Accelerator position • Vehicle speed

The gear shifting process is continuously adapted, dependent on the driving style, the driving situation and the road characteristics.

Important! When parking the vehicle or 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 firmly on the brake pedal, the vehicle could accelerate quickly forward on in reverse. You could lose control of the vehicle 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 a lower gear = maximum acceleration. Once the desired speed is attained, ease up on the accelerator — the transmission shifts up again.

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” and hold the vehicle with the service brake. When stopping the vehicle on an uphill gradient, do not hold it with the accelerator, use the brake. This avoids unnecessary transmission heat build up.

Maneuvering To maneuver in tight areas, e.g. when pulling into a parking space, control the vehicle speed by gradually releasing the brakes. Accelerate gently and never abruptly step on the accelerator. To rock a vehicle out of soft ground (mud or snow), alternately shift from forward to reverse, while applying slight partial throttle.

Rocking a vehicle free in this manner may cause the ABS or traction system malfunction indicator lamp to come on. Turn off and restart the engine to clear the malfunction indication.

Warning! Getting out of your vehicle with the selector lever not fully engaged in position “P” is dangerous. Also, when parked on an 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”, see page 243 for parking brake. When parked on an incline, also turn front wheel against curb.

Selector lever position

1 Program mode indicator,

see page 241

2 Gear range indicators

The current selector lever position is highlighted in the gear range indicator display (2), as well as shown by a red indicator light next to the gear selector lever. The automatic gear shifting process can be adapted to specific operating conditions using the selector lever.

Park position The park position is to be used when parking the vehicle. Engage only with the vehicle stopped. The park position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should always use the parking brake in addition to placing the selector lever in park to secure the vehicle.

Note: The electronic key can only be removed from the starter switch with the selector lever in position “P”. With the electronic key removed, the selector lever is locked in position “P”. Reverse gear Shift to reverse gear only with the vehicle stopped. Dependent on the program mode selector switch position “S” or “W” the maximum speed in the reverse gear is different. However, it is not possible to change the program mode while in reverse.

Neutral No power is transmitted from the engine to the drive 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 250 for winter driving instructions).

Important! Coasting the vehicle, or driving for any other reason with selector lever in “N” can result in transmission damage that is not covered by the Mercedes-Benz Limited Warranty. The transmission automatically upshifts through 5th gear. Position “D” provides optimum driving characteristics under all normal operating conditions.

Gear selection for special circumstances The transmission gear ranges for special circumstances can be selected by pressing the selector lever to the right or the left with the selector lever in position “D”. The gear range currently selected is highlighted in the instrument cluster display. Briefly press selector lever in the ç direction: The transmission downshifts, one gear at a time, in the order “4”, “3”, “2”, “1”. Press and hold selector lever in the ç direction: The selector lever position display will switch to the gear range currently selected by the automatic transmission. The transmission will only shift down one gear if the gear range currently selected has already shifted to its highest possible gear. Briefly press selector lever in the æ direction: The transmission will shift from the current gear range to the next higher gear range. If the transmission is already in gear range “D”, an additional upshift of one gear is possible.

Press and hold selector lever in the æ direction: The transmission will shift from the current gear directly to gear range “D”.

Warning! On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle’s ABS will not prevent this type of loss of control.

Important! With transmission in gear range “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.

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 overrevving the engine when the selector lever is moved to a lower gear range, the transmission will not shift to a lower gear, if the engine’s revolutions per minute limit would be exceeded. In this case there will be no downshift, even when the vehicle speed reaches the engine’s rpm limit of that gear, e.g. by applying the service brakes. To prevent the engine from laboring at low RPM when driving uphill gradients or with your vehicle heavily loaded, the automatic transmission will downshift when necessary to maintain engine RPM within the best torque range.

Gear ranges:

240

Upshift through 4th gear only. Suitable for performance driving. Upshift through 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.

Upshift through 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. Use this position, which makes maximum use of the engine’s braking effect, while descending very steep or lengthy downgrades and only at speeds below 40 mph (60 km/h).

Program mode selector switch

The transmission is provided with a selector switch (1) for Standard “S” and Winter/Wet (snow and ice) “W” program modes. The program mode currently selected is indicated in the gear range indicator display.

Standard mode Press switch. “S” is displayed in the gear range indicator display, see page 237. Use this mode for all regular driving. The vehicle starts out in 1st gear. Accelerator Operation: Fast on = depressing the accelerator pedal quickly (not into kickdown position) while driving continuously, rather than depressing the accelerator pedal in the usual manner, will cause the automatic transmission to shift down into a lower gear. This gear shifting process is dependent on the current vehicle speed. Fast off = there will be no upshift when releasing the accelerator pedal quickly, e.g. using the engine’s braking power during performance driving.

W Winter/Wet (snow and ice) mode

Press switch. “W” is displayed in the gear range indicator display, see page 237. The vehicle starts out in 2nd gear, except with selector lever in 1st gear, or with accelerator pedal in kick-down position. The “W” mode helps to improve traction and driving stability of the vehicle. The gear shifting process occurs at lower vehicle and engine speeds than in the “S” program mode.

Caution! Never change the program mode when the selector lever is out of position “P”. It could result in a change of driving characteristics for which you may not be prepared.

Important! Always be certain of the program mode selected since the vehicle driving characteristics change with the selection of the program mode. Dependent on the program mode selector switch position “S” or “W” and the gear selector lever in position “R”, the ratio of power transmission changes.

Emergency operation (Limp home mode) If vehicle acceleration worsens or the transmission no longer shifts, the transmission is most likely operating in Limp Home Mode which engages when there is a malfunction of the transmission. This condition may be accompanied by the “CHECK ENGINE” malfunction indicator lamp in the instrument cluster coming on. In this mode only the 2nd gear or reverse gear can be activated.

To engage 2nd gear or reverse:

1. Stop the vehicle. 2. Move selector lever to position “P”. 3. Turn off the engine. 4. Wait approximately 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 Center as soon as possible.

Parking brake

To engage, firmly depress parking brake pedal. When the electronic key is in starter switch position 2, the brake warning lamp in the instrument cluster should come on brightly. To release the parking brake, pull handle on instrument panel. The brake warning lamp in the instrument cluster should go out. A warning sounds and the parking brake warning message appears in the multifunction display (see page 279), if you start to drive without having released the parking brake. Also see brake warning lamp on page 270.

Warning! When leaving the vehicle always remove the electronic key from the starter switch, and lock the vehicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. Children could release the parking brake, which could result in an accident or serious injury.

Drinking and driving

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 Center.

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

Warning! Drinking or taking drugs and driving can be a very dangerous combination. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgement. The possibility of a serious or even fatal accident is sharply increased when you drink or take drugs and drive. Please don’t drink or take drugs and drive or allow anyone to drive after drinking or taking drugs.

Pedals

Warning! Keep driver’s foot area clear at all times. Objects stored in this area may impair pedal movement.

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 to obtain expected braking effect. 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 vehicle in sufficient time to avoid an accident.

The condition of the parking brake system is checked each time the vehicle is in the shop for the required maintenance 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 Center immediately. All checks and service work on the brake system should be carried out by an authorized Mercedes-Benz Center. 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 to use the engine’s braking power. 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.

Driving off Apply the service brakes to test them 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. When starting off on a slippery surface, do not allow one drive wheel to spin for an extended period with the ESP switched off. Doing so may cause serious damage to the drive train which is not covered by the Mercedes-Benz Limited Warranty.

246

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 service brake pedal. 2. Firmly depress parking brake pedal. 3. Move the selector lever to position “P”

(manual transmission: first or reverse gear).

4. Slowly release service brake pedal. 5. Turn front wheels towards the road curb. 6. Turn the electronic key to starter switch

position 0 and remove.

7. Take the electronic 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” (manual transmission: first or reverse gear). When parking on hills, always set the parking brake.

Tires

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 warning 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 Center or tire dealer for repairs.

Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approximately 1/16 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.

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 vehicle. 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.

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.

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 are close to the freezing point.

Tire speed rating Vehicles without Sport Package: Your vehicle is factory equipped with “H”-rated tires, which have a speed rating of 130 mph (210 km/h). An electronic speed limiter prevents your vehicle from exceeding the speed rating.

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 rated 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 not snow or ice covered.

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.

Snow chains Use only snow chains that are tested and recommended by Mercedes-Benz. Your authorized Mercedes-Benz Center will be glad to advise you on this subject. Chains should only be used on the rear wheels. Follow the manufacturer’s mounting instructions. Snow chains should only be driven on snow covered roads at speeds not to exceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow. When driving with snow chains, press the ESP control switch to OFF, refer to page 262.

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” or in case of manual transmission declutch. 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 be 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 vehicle not facing the wind.

Winter driving Have your vehicle winterized at your authorized Mercedes-Benz Center before the onset of winter. • Change the engine oil if the engine contains an oil

which is not approved for winter operation. For viscosity (SAE/CCMC class) and filling quantity, see page 357.

• Check engine coolant anticorrosion/antifreeze

concentration.

• Additive for the windshield washer and headlamp

cleaning system: Add MB Concentrate “S” to a premixed windshield washer solvent/antifreeze which is formulated for below freezing temperatures, see page 302.

• Test battery: Battery capacity drops with decreasing ambient temperature. A well charged battery helps to ensure that the engine can be started, even at low ambient temperatures.

• Tires: We recommend M+S rated radial-ply tires on

all four wheels for the winter season. Observe permissible maximum speed for M+S rated radial-ply tires and the legal speed limit.

Note: In winter operation, the maximum effectiveness of the antilock brake system (ABS) and electronic stability program (ESP) can only be achieved with M+S rated radial-ply tires and/or snow chains recommended by Mercedes-Benz. Snow chains maximize performance.

Block heater (Canada only) The engine is equipped with a block heater. The electrical cable may be installed at your authorized Mercedes-Benz Center.

252

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 passenger compartment, 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. The trunk is the preferred place to carry objects.

Traveling abroad Abroad, there is a widely-spread Mercedes-Benz service network at your disposal. If you plan to travel into areas which are not listed in the index of your Mercedes-Benz Center directory, you should request pertinent information from your authorized Mercedes-Benz Center.

Cruise control

The cruise control allows you to drive in a more relaxed manner, for example over long distances, as it automatically maintains the set speed by actively regulating the throttle setting. Any given speed above approximately 25 mph (40 km/h) can be maintained with the cruise control by operating the lever.

254

1 Accelerate and set:

Lift lever briefly to set speed. Hold lever up to accelerate.

2 Decelerate and set:

Depress lever briefly to set speed. 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 then be released. The speed can be increased (e.g. for passing) by using the accelerator. After 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 lever in the appropriate direction for increases or decreases in 0.6 mph (1 km/h) increments. When the lever is released, the newly set speed remains.

3 Canceling

4 Resume

To cancel the cruise control, briefly push lever to position 3. When you step on the brake pedal or the vehicle speed drops below approximately 25 mph (40 km/h), 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 Center as soon as possible.

If the lever is briefly pushed to position 4 when driving at a speed exceeding approximately 25 mph (40 km/h), the vehicle resumes the speed which was set prior to the cancellation of the cruise control. The last memorized speed is canceled when the electronic key in the starter switch is turned to position 1 or 0.

Important! Moving gear selector lever to position “N” switches the cruise control off.

Vehicles with automatic transmission: Downshift occurs (max. to 3rd gear) to maintain the set cruise controlled speed by using the engine’s braking power. As soon as the grade eases, the automatic transmission shifts up again dependent on the selector lever position.

Vehicles with manual transmission: The set cruise controlled speed is switched off when declutching exceeds four seconds during downshifting a gear.

Nevertheless, in some cases you may have to step on the brake pedal to slow down. In this case the cruise control is switched off. Use the lever to resume the previously set speed.

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.

Notes: 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. In this case the following will assist in maintaining the set cruise controlled speed:

Applying the brakes very quickly results in maximum BAS assistance. To receive the benefit of the system you must apply continuous full braking power during the stopping sequence. Do not reduce brake pedal pressure. Once the brake pedal is released, the BAS is deactivated. If the BAS warning message is displayed, a malfunction has been detected in the system. The brake system functions in the usual manner, but without BAS. With the ABS malfunctioning, the BAS is also switched off. If a BAS warning message is displayed, have the BAS checked at your authorized Mercedes-Benz Center as soon as possible.

Brake assist system (BAS)

Warning! BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. The BAS 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 a BAS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

The BAS is designed to maximize the vehicle’s braking capability during emergency braking maneuvers by having maximum power boost applied to the brakes more quickly in emergency braking conditions than might otherwise be afforded solely by the driver’s braking style. This can help reduce braking distances over what ordinary driving and braking style might do. The BAS complements the antilock brake system (ABS).

Antilock brake system (ABS)

Warning! Do not pump the brake pedal, rather use firm, steady brake pedal pressure. Pumping the brake pedal defeats the purpose for ABS and significantly reduces braking effectiveness.

Important! The ABS improves steering control of the vehicle during hard braking maneuvers. The ABS prevents the wheels from locking up above a vehicle speed of approximately 5 mph (8 km/h) independent of road surface conditions.

258

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. Keep firm and steady pressure on the brake pedal while experiencing the pulsation. Continuous steady brake pedal pressure results in applying the advantages of the ABS, namely braking power and ability to steer the vehicle. In the case of an emergency brake maneuver keep continuous full pressure on the brake pedal. In this manner only can the ABS be most effective. On slippery road surfaces, the ABS will respond even with light brake pedal pressure because of the increased likelihood of locking wheels. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.

ABS control The ABS malfunction indicator lamp - in the instrument cluster comes on with the electronic key in starter switch position 2 and should go out with the engine running. When the ABS malfunction indicator lamp in the instrument cluster comes on while the engine is running, 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. For ABS malfunction indicator lamp, see page 272. With the ABS malfunctioning, the BAS and ESP are also switched off. Both malfunction indicator lamps come on with the engine running. If the charging voltage falls below 10 volts, the malfunction indicator lamp comes on and the ABS is switched off. When the voltage is above this value again, the malfunction indicator lamp should go out and the ABS is operational.

If the ABS malfunction indicator lamp stays illuminated, have the system checked at your authorized Mercedes-Benz Center as soon as possible.

Warning! ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. 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 a ABS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

Note: To alert following vehicles to slippery road conditions you discover, operate your hazard warning flashers as appropriate.

Important! If the ESP warning lamp v 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.

• Do not switch off the ESP.

Caution! If the vehicle is towed with the front axle raised (see page 321, “Towing the vehicle”), the engine must be shut off (electronic key in starter switch position 0 or 1). Otherwise, the ESP will immediately be engaged and will apply the rear wheel brakes.

Electronic stability program (ESP)

Warning! ESP cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded. The ESP cannot prevent accidents, including those resulting from excessive speed in turns, or aquaplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

The ESP enhances directional control and reduces driving wheel spin of the vehicle under various driving conditions. Over/understeering of the vehicle is counteracted by applying brakes to the appropriate wheel to create a countervailing vehicle movement. Engine torque is also limited. The ESP warning lamp, located in the speedometer dial, starts to flash when ESP is in operation.

Notes: The yellow ESP warning lamp v in the speedometer dial comes on with the electronic key in starter switch position 2. It should go out with the engine running. If the ESP warning message is displayed, a malfunction has been detected in the system. Pressing the accelerator pedal will require greater effort. Only partial engine output will be available. Have the ESP checked at your authorized Mercedes-Benz Center as soon as possible.
