2000 Mercedes-benz M Class Owners Manual

1 Observe all legal requirements.

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.

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 2 000 miles (Canada: 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 87. We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz Light Truck 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. Check regularly and before a long trip, see page 215.

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 the system is not activated the indicator lamp in the “SOS” button stays on after turning electronic key in starter switch to position 2 and the message “TELE AID – NOT ACTIVATED” will be shown in the MCS display for approx. 10 seconds. 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.

148

The Tele Aid system is operational providing that the vehicle’s battery is charged, properly connected, not damaged and cellular and GPS coverage is available. The speaker volume of a Tele Aid call can be adjusted using the volume control on the MCS unit. To activate, press the “SOS” button, the Roadside Assistance button • or the Information button ¡, depending on the type of response required. Shortly after the completion of your Acquaintance Call, you will receive a user ID and password via first call mail. By visiting www.mbusa.com and selecting “Tele Aid” (USA only), you will have access to account information, remote door unlock, Info Services* profile and more.

* Optional

System self-check Initially, after turning the key in steering lock to position 2, malfunctions are detected and indicated (the indicator lamps in the “SOS” button, the Roadside Assistance button • and Information button ¡ stay on longer than 10 seconds or do not come on). The message “TELE AID – PLEASE VISIT WORKSHOP” appears in the MCS display.

Important! Always make sure that the indicator lamps in the “SOS” button, the Roadside Assistance button • and the Information button ¡ do not remain illuminated constantly in red and the message “TELE AID – VISIT WORKSHOP” is not displayed in the MCS display after the system self check. If a malfunction is indicated as outlined above, have the system checked at the nearest Mercedes-Benz Light Truck Center as soon as possible.

Emergency calls An emergency call is initiated automatically: • following an accident in which the Emergency Tensioning Retractors (ETR’s) or airbags deploy,

• if the antitheft alarm or the tow away alarm stays on

for more than 20 seconds, see pages 35 and 36.

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 – CONNECTING CALL” appears in the MCS display. When the connection is established, the message “EMERGENCY CALL – CALL CONNECTED” appears in the MCS 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. When a voice connection is established the audio system mutes and the message “TELE AID – EMERGENCY CALL ACTIVE” appears in the MCS display. The Response Center will attempt to determine more precisely the nature of the accident provided they can speak to an occupant of the vehicle.

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 completed. Once a call is concluded, a chirp will be heard and the appropriate indicator lamp will stop flashing. The MCS system operation will resume.

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.

Notes: The indicator lamp for the respective button flashes until the call is concluded and this can only be completed by a Response Center or Client Assistance Center representative, except Roadside assistance and Information calls, which can also be terminated by using the End button on the MCS unit. When a Tele Aid call has been initiated, the MCS system audio is muted and the selected mode (radio, tape or CD) pauses. The optional cellular phone (if installed) switches off. If you must use this phone, the vehicle must be parked. Disconnect the coiled cord and place the call. The navigation system (if engaged) will continue to run. A pop-up window will appear in the MCS display to indicate that a Tele Aid call is in progress.

Remote door unlock In the case you have your vehicle locked unintentionally (e.g. key inside vehicle), and the reserve key is not handy, contact the Mercedes-Benz Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada). You will be asked to provide your password which you provided when you completed the subscriber agreement. Then return to your vehicle and pull outside handle of liftgate for a minimum of 20 seconds until the “SOS” button is flashing.

Catalytic converter

160

Catalytic converter Your Mercedes-Benz is equipped with monolithic type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial control of the pollutants in the exhaust emissions. Keep your vehicle in proper operating condition by following our recommended maintenance instructions as outlined in your Service Booklet.

Caution! To prevent damage to the catalytic converters, use only premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, excessive unburned fuel may reach the catalytic converter causing it to overheat, which could start a fire.

Warning! As with any vehicle, do not idle, park or operate this vehicle in areas where combustible materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

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 Light Truck 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.

Steering lock

1 Steering is unlocked.

(If necessary, move steering wheel slightly to allow the key to be turned clockwise to position 1.) Most electrical consumers can be operated. For detailed information see respective subjects.

2 Driving position. 3 Starting position. See page 164 for starting and turning off the engine.

Warning! When leaving the vehicle always remove the key from the steering lock, 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.

0 The key can be withdrawn in this position only. The steering is locked when the key is removed from the steering lock. If necessary, move steering wheel slightly to allow the locking mechanism to engage. The key can only be removed with the selector lever in position “P”. After removing the key or with the key in steering lock position 0, the selector lever is locked in position “P”.

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

Notes: A warning sounds when the driver’s door is opened while the key is in steering lock 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.

Starting and turning off the engine

164

Starting and turning off the engine

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

Starting Do not depress accelerator. Briefly turn key in steering lock clockwise to the stop and release. The starter will engage until the engine is running. If engine will not run, and the starting procedure stops, turn key completely to the left and repeat starting the engine. After several unsuccessful attempts, have the system checked at the nearest authorized Mercedes-Benz Light Truck Center. A starting procedure can be interrupted by turning the key to steering lock position 0.

Important! Due to the installed starter non-repeat feature, the 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 Light Truck Center will advise you on this subject.

Note: In case the engine cannot be started and the messages Á and î are shown in the odometer display field, the system is not operational. Contact an authorized Mercedes-Benz Light Truck Center or call 1-800-FOR-MERCedes (in the USA), or 1-800-387-0100 (in Canada).

Turning off Turn the key in the steering lock to position 0 to stop the engine. The key can only be removed with the selector lever in position “P”.

Automatic transmission

The automatic transmission selects individual gears automatically, dependent upon • Selector lever position • 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”.

Automatic transmission

166

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 or 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 173 for parking brake. When parked on an incline, also turn front wheel against curb.

Warning! When leaving the vehicle always remove the key from the steering lock, and lock the vehicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. Children could move the gear selector lever from position “P”, which could result in an accident or serious injury.

Towing a trailer

If the transmission hunts between gears on inclines, manually shift to a lower gear (select “4”, “3”, “2” or “1”). A lower gear and reduction of speed reduces the chance of engine overloading and/or overheating. At very steep inclines, not manageable with selector lever in position “1”, switch transfer case to LOW RANGE, see page 209 for instructions on how to engage LOW RANGE. For instructions on trailer towing refer to page 190.

Selector lever position

The current selector lever position is indicated in the gear range indicator display. 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. Notes: The key can only be removed from the steering lock with the selector lever in position “P”. With the key removed, the selector lever is locked in position “P”. With a malfunction in the vehicle’s electrical system the selector lever could remain locked in position “P”. To unlock the selector lever manually, see page 259. Reverse gear Shift to reverse gear only with the vehicle stopped.

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 winter driving instructions on page 180). 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 indicated 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. Continue driving in the usual manner. The transmission will then shift down automatically. 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:

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).

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 Light Truck Center as soon as possible.

Parking brake

To engage, firmly depress parking brake pedal (1). When the key is in steering lock position 2, the brake warning lamp É in the instrument cluster should come on brightly.

To release the parking brake, pull handle (2) on instrument panel. The brake warning lamp É in the instrument cluster should go out. A warning sounds, if you start to drive without having released the parking brake. Also see brake warning lamp on page 219.

Warning! When leaving the vehicle always remove the key from the steering lock, 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 Light Truck 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 and there is no audible warning (EBP), 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 Light Truck Center immediately. All checks and service work on the brake system should be carried out by an authorized Mercedes-Benz Light Truck 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.

176

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 the service brake pedal. 2. Firmly depress parking brake pedal. 3. Move the selector lever to position “P”. 4. Slowly release the service brake pedal. 5. Turn front wheels towards the road curb. 6. Turn the key to steering lock position 0 and

remove.

7. Take the key and lock vehicle when leaving.

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

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 Light Truck 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.

Warning! Do not allow your tires to wear down too far. As tread depth approaches 1/16 in (1.5 mm), the adhesion properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Specified tire pressures must be maintained. This applies particularly if the tires are subjected to high loads (e.g. high speeds, heavy loads, high ambient temperatures).

Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the 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.

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.

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 with a minimum tread depth of approximately 1/8 in (4 mm) 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.

Tire speed rating ML 320 and ML 430: 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 tire speed rating. ML 55 AMG: Your vehicle is factory equipped with “W”-rated tires, which have a speed rating of 168 mph (270 km/h). Despite the tire rating, local speed limits should be obeyed. Use prudent driving speeds appropriate to prevailing conditions.

Warning! Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires. Exceeding the maximum speed for which tires are rated can lead to sudden tire failure causing loss of vehicle control and resulting in personal injury and possible death.

Snow chains Use only snow chains that are tested and recommended by Mercedes-Benz. Your authorized Mercedes-Benz Light Truck Center will be glad to advise you on this subject. Snow chains should be used on all four wheels. With only two chains available, they should be mounted 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 207.

Model ML 55 AMG Use of snow chains is not permissible with tire size 285/50 R 18.

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 instructions The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, move selector lever to position “N”. Try to keep the vehicle under control by corrective steering action.

Caution! Do not use LOW RANGE mode when driving on ice or packed snow. At speeds below 18 mph (30 km/h) vehicle steering is adversely affected by the LOW RANGE ABS. 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.

Winter driving Have your vehicle winterized at your authorized Mercedes-Benz Light Truck 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 292.

• 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 237.

• 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.

In winter operation, the maximum effectiveness of the antilock brake system (ABS), the four wheel electronic traction system (4-ETS+), the electronic stability program (ESP), and electronic brake proportioning (EBP) can only be achieved with M+S rated radial-ply tires and/or snow chains recommended by Mercedes-Benz. Snow chains maximize performance. For driving instructions using snow chains see page 179.

Deep water

Caution! Do not drive through flooded areas or water of unknown depth. Before driving through water, determine its depth. It should not be deeper than approximately 20 inches (50 cm). 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.

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 Light Truck Center directory, you should request pertinent information from your authorized Mercedes-Benz Light Truck Center.

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.

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

Off-Road driving Familiarize yourself with the vehicle characteristics and gear changing before you attempt any difficult terrain off-road driving. We recommend that you start out with easy off-road travel. Please read this chapter carefully before you begin off-road travel. Special driving features are available for specific kinds of operation: • LOW RANGE mode, see page 209
• LOW RANGE - ABS, see page 202
• LOW RANGE - 4-ETS+, see page 204
• LOW RANGE - ESP, see page 208
Engage the LOW RANGE mode before driving under off-road conditions. For switching LOW RANGE mode on and off see page 209. Fasten items being carried as securely as possible, see page 136. We recommend to keep doors, liftgate, windows, and roof closed whenever driving in off-road mode.

Important! Adjust vehicle speed to condition of terrain. The more uneven, rutty and steeper the terrain, the lower the speed should be. Watch out for obstacles, such as rocks, holes, tree-stumps, ruts. Be especially careful when driving in unknown territory. Eventually get out of the vehicle and scout the path you intend to take. Continuous and speedy driving in sandy soil overcomes the vehicle rolling resistance, and helps to prevent the vehicle from sinking into the ground. Do not initiate jumps with the vehicle. It interrupts the forward momentum of the vehicle. Sand, dirt, mud and other material having friction property, can cause exceptional wear and tear as well as failure of the brakes. In this case the brakes may be less effective or even fail when you most need them. Always clean and check the brakes following each off-road trip.

Checklist before off-road driving • Tires: Check the tread depth and maintain specified tire pressure (see tire pressure label inside the fuel filler flap). Check tires for possible damage and remove foreign objects. The valve caps must be mounted.

• Rims: Dented or bent rims can cause tire pressure

loss and damage the tire beads. For this reason change rims before driving off-road.

• Vehicle tool kit: Check if the vehicle jack is

functional. In all cases take the vehicle tool kit, a strong tow rope, a shovel and a small plank (to put under the vehicle jack on sandy soil) with you.

Driving in steep terrain

Slope angle: 1 26° (ML 320 and ML 430)

23° (ML 55 AMG)

2 26° (ML 320 and ML 430)

21° (ML 55 AMG)

Switch to LOW RANGE mode before starting to drive up or down steep inclines, see page 209. Maximum vehicle climbing ability is a 60% grade.

Driving on embankments, slopes and other steep inclines should only be done straight up or downhill, i.e. in the line of gravity. Do not drive along the side of a slope (danger of vehicle rollover). If in doing so, the vehicle begins to show a tendency to roll, immediately steer into a line of gravity (straight up or downhill). To help avoid the vehicle rolling over, never turn it around on steep inclines. If the vehicle cannot complete the attempted climb, back it down in reverse gear. Utilize the engine’s braking power when descending a slope, observe the engine speed (do not overrev the engine). Apply the service brake as needed. Check the brakes after a lengthy downgrade drive.

Notes: Avoid excessive engine speeds – drive with moderate engine speeds (max. 3000 RPM). Select gear range “2” or “1” on the automatic transmission, see page 165.

Traction in steep terrain: Be easy on the accelerator and watch for continuous wheel traction when driving in steep terrain. The 4-ETS+ helps greatly when starting out on a steep incline. The front wheels have then the tendency to slip due to the weight reduction over the front axle. The ETS recognizes the situation and limits the torque for the front wheels by braking them. Simultaneously the torque for the rear wheels is increased. See page 203 for four wheel electronic traction system (4-ETS+).

Driving across a hilltop: To prevent the vehicle from speeding up too much after climbing a hill, decelerate just ahead of a hilltop (do not select gear range “N”). Use the momentum of the vehicle to drive across the hilltop. Driving in this manner prevents the vehicle from jumping across the hilltop and thus loosing its forward momentum.

Driving downhill: Select gear range “1” on the automatic transmission, see page 165. Drive downhill observing the same rules as driving uphill. Driving on embankments, slopes and other steep inclines should only be done straight up or downhill, i.e. in the line of gravity. Do not drive along the side of a slope (danger of vehicle rollover). If in doing so, the vehicle begins to show a tendency to roll, immediately steer into a line of gravity (straight up or downhill).

Utilize the engine’s braking power when descending a slope, observe the engine speed (do not overrev the engine). Apply the service brake as needed. The special low range ABS setting allows for precise and brief (cyclical) blocking of the front wheels, permitting them to dig into loose ground. Remember that the front wheels when stopped, slide across a surface, thus loose their ability to steer the vehicle. Check the brakes after a lengthy downgrade drive.

Important! Only apply the service brake if the vehicle travels straight downhill, i.e. in the line of gravity.

Driving through water

Switch to LOW RANGE mode before driving through water. Switch off the exterior lamps as well as the climate control. Enter the water only at a shallow spot. Never take a running start. Drive slowly, avoiding a bow wave. Do not stop vehicle immersed in water, and do not shut off the engine. To dry the brakes, apply pressure to the brake pedal several times after leaving the water.

1 20 in (50 cm)

Before driving through water, determine its depth. It should not be deeper than approximately 20 inches (50 cm).

Notes: Check the vehicle clearance before crossing obstacles that possibly could damage the undercarriage. If possible use the assistance of a second person. Special attention is needed when crossing obstacles on a steep incline. The vehicle could slide sideways as a result of its possible slanted position.

Ruts: Select gear range “1” on the automatic transmission, see page 165. A number of off-road tracks or other byways have deep ruts which can cause the undercarriage to come in contact with the ground. Drive next to the ruts rather than through them if at all possible.

Notes: Check the vehicle clearance. Damage on the vehicle definitely increases the chance for a subsequent accident.

Crossing obstacles: Select gear range “1” on the automatic transmission, see page 165.

Cross obstacles (e.g. tree stumps or big rocks) very slowly by aiming one of the front wheels at the center of the obstacle, and repeat same with the rear wheel.

Important! Damage on the vehicle definitely increases the chance for a subsequent accident.

Returning from off-road driving Off-road driving increases strain on the vehicle. We recommend that you inspect the vehicle for possible damage after each off-road trip. Recognizing any damage and a subsequent timely repair reduces the chance of a possible breakdown or accident later on. Proceed as follows: • Switch off the LOW RANGE mode, see page 209. • Remove excessive dirt from tires, wheels, wheel

housings, and underbody. For instance, after driving in mud, clean the radiator, chassis, engine, brakes, and wheels from extreme dirt, using a strong jet of water.

• Inspect frame, oil pan, brake hoses, etc., as well as

vehicle underbody for possible damage.

• Check tires for possible damage, clean all exterior

lamps, and conduct a brake test.

• Check for brush or branches caught in the

undercarriage. They could increase the possibility of a fire, as well as cut fuel and/or brake lines, puncture rubber bellows of the axles or drive shafts.

Warning! If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to
