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. For ESP warning message, see page 273. 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 ESP may activate (yellow ESP warning lamp in speedometer dial 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 ESP will immediately be engaged and will apply the rear wheel brakes. In winter operation, the maximum effectiveness of the ESP is only achieved with Mercedes-Benz recommended M+S rated radial-ply tires and/or snow chains.
Synchronizing ESP If the power supply was interrupted (battery disconnected or empty), the ESP warning message may be displayed with the engine running. Turn steering wheel completely to the left and then to the right. The ESP warning message should go out.

To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand or gravel, switch off ESP by pressing the upper half (1) of the ESP switch. The ESP warning lamp v located in the speedometer dial, is continuously illuminated.
Warning! When the ESP warning lamp is illuminated continuously, the ESP is switched off. Adapt your speed and driving to the prevailing road conditions.
With the ESP system switched off, the engine torque reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ESP is unavailable. Adapt your speed and driving to the prevailing road conditions. A portion of the ESP 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).
Notes: Avoid spinning of one drive wheel. This may cause serious damage to the drive train which is not covered by the Mercedes-Benz Limited Warranty. The ESP 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 return to the enhanced vehicle stability offered by ESP: press lower half (2) of the switch (the ESP warning lamp in the speedometer dial goes out).
Important! If the ESP warning lamp flashes: • During take-off, apply as little throttle as possible. • While driving, ease up on the accelerator.

Malfunction and indicator lamps in the instrument cluster
General information: If a bulb in the instrument cluster fails to light up during the bulb self-check when turning the electronic key in steering lock to position 2, have it checked and replaced if necessary.
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 authorized Mercedes-Benz Center qualified 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.
On-board diagnostic system Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the “CHECK ENGINE” malfunction indicator lamp comes on when the engine is running,
it indicates a malfunction of the fuel management system, emission control system, systems which impact emissions, or the fuel cap is not closed tight (check the fuel cap). If the “CHECK ENGINE” lamp is illuminated continuously and the vehicle is driving normally, you
may still drive the vehicle, however, in all cases, we recommend that you have the system checked at your authorized Mercedes-Benz Center as soon as possible. If the “CHECK ENGINE” lamp is flashing and/or the vehicle is not driving normally (e.g. malfunction of the fuel management system or running out of fuel), serious damage can occur to the emission system. Please contact your authorized Mercedes-Benz Center immediately. 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 Center as soon as possible. With some exceptions, the control module switches off the “CHECK ENGINE” malfunction indicator lamp if the condition, causing the lamp to come on, no longer exists during three consecutive cycles. An on-board diagnostic connector is located in the passenger compartment near to the parking brake pedal, allowing the accurate identification of system malfunctions through the readout of diagnostic trouble codes.

Brake warning lamp
Except Canada
Canada only
When the brake warning lamp and message appear while the engine is running, this means: • there is insufficient brake fluid in the reservoir (engine running and parking brake released), or
• the parking brake is set (engine running).
Warning! Driving with the brake warning lamp illuminated 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.
Note: If you find that the minimum mark on the brake fluid reservoir is reached, have the brake system checked for brake pad thickness and leaks.
Supplemental restraint system (SRS) indicator lamp
Fuel reserve warning
The operational readiness of the airbag system is verified by the indicator lamp “SRS” in the instrument cluster when
turning the electronic key in starter switch to position 1 or 2. 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.
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 Center 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 unnecessarily which could also result in injury.
See page 65 for notes on airbags, see page 63 for belt tensioners and page 55 for infant and child seat restraint.

ABS malfunction indicator lamp
ABS
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 symbol and warning in the instrument cluster remains illuminated 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. A malfunctioning ABS control unit can possibly affect the operation of other systems (e.g. Navigation, Automatic transmission). Be guided accordingly with respect to the use of those systems and have the system checked at your authorized Mercedes-Benz Center as soon as possible.
With the ABS malfunctioning, the BAS and ESP are also switched off. The malfunction indicator lamps and malfunction messages in the multifunction display 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. Have the system checked at your authorized Mercedes-Benz Center as soon as possible. See page 258 for notes on antilock brake system (ABS).
Malfunction and indicator lamp in the center console
AIRBAG OFF indicator lamp The ü indicator lamp will light up for approximately 6 seconds when you turn the electronic key in starter switch to position 1 or 2. It does not light up if there is a fault in the system. The ü indicator lamp stays lit as long as a Baby SmartTM child seat is properly installed on the front passenger seat. It indicates that the front passenger airbag is switched off. See page 62 for BabySmartTM airbag and its deactivation system.
Electronic stability program (ESP) — warning lamp
