2000 Mercedes-benz M Class Owners Manual

• if ignition is “on” and the engine is turned

manually.

If you see flames, steam or smoke coming from the engine compartment, or if the coolant temperature gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not open the hood until the engine has cooled. If necessary, call a fire department.

Checking engine oil level

1 Oil dipstick 2 Oil filler cap

To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check engine oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan.

Wipe oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three seconds to obtain accurate reading.

Oil level must be between the lower (min) and upper (max) mark of the dipstick.

Fill quantity between upper and lower dipstick marking, the level is approximately 2.1 US qt (2.0 l). Do not overfill the engine. Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered by the Mercedes-Benz Limited Warranty. See page 224 for low engine oil level warning.

Note: See page 89 for engine oil level indicator.

Automatic transmission fluid level The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or gear shifting malfunctions, have your authorized Mercedes-Benz Light Truck Center check the transmission fluid level.

Engine oil consumption Engine oil consumption checks should only be made after the break-in period. During the break-in period, higher oil consumption may be noticed and is normal. Frequent driving at high engine speeds results in increased consumption.

234

Coolant level

P20.30-0241-20

To check the coolant level, the vehicle must be parked on level ground and the engine stopped. Check coolant level only when coolant is cold. The coolant level should reach the COLD LEVEL mark in the reservoir.

Adding coolant If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. After adding coolant, close cap until you hear it click a few times. The drain plugs for the cooling system are located on the left and right side of the engine block directly above the engine mounts and at the bottom of the radiator. Anticorrosion/antifreeze mixture, see page 297.

Warning! In order to avoid possible serious burns or injury:

• Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.

• Do not remove pressure cap on coolant

reservoir if engine temperature is above 194°F (90°C). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.

• Using a rag, slowly open cap approximately

1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure.

• Do not spill antifreeze on hot engine parts.

Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts.

Wheels Replace rims or tires with the same designation, manufacturer and type as shown on the original part. See your authorized Mercedes-Benz Light Truck Center for further information.

Warning! Do not mix different tire construction types (i.e. radial, bias, bias-belted) on your vehicle because handling may be adversely affected and may result in loss of control.

See your authorized Mercedes-Benz Light Truck Center for information on tested and recommended rims and tires for summer and winter operation. They can also offer advice concerning tire service and purchase.

240

Tire replacement Front and rear tires should be replaced in sets. Furthermore – in the event of tire replacement – the optional regular size spare wheel should be used on the rear axle. Rims and tires must be of the correct size and type. For dimensions, see technical data on page 288. We recommend that you break in new tires for approximately 60 miles (100 km) at moderate speed. It is imperative that the wheel mounting bolts be fastened to a tightening torque of 110 ft.lb. (150 Nm) whenever wheels are mounted. For rim and tire specifications, refer to technical data on page 288.

Warning! Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them. When replacing rims, use only genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident.

Rotating wheels The wheels can be rotated according to the degree of tire wear while retaining the same direction of travel. Rotating, however, should be carried out as recommended by the tire manufacturer, before the characteristic tire wear pattern (shoulder wear on front wheels and tread center wear on rear wheels) becomes visible, as otherwise the driving properties deteriorate.

Important! Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward movement.

Notes: Thoroughly clean the inner side of the wheels any time you rotate the wheels or wash the vehicle underside. The use of retread tires is not recommended. Retread tires may adversely affect the handling characteristics and safety of the vehicle. Dented or bent rims can cause tire pressure loss and damage to the tire beads. For this reason, check rims for damage at regular intervals. The rim flanges must be checked for wear before a tire is mounted. Remove burrs, if any. Check and ensure proper tire inflation pressure after rotating the wheels. For tire inflation pressure see page 250.

Tire inflation pressure A table (see fuel filler flap) lists the tire inflation pressures specified for Mercedes-Benz recommended tires as well as for the varying operating conditions.

Important! Tire pressure changes by approximately 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage – especially in the winter. Example: If garage temperature = approximately +68°F (+20°C) and ambient temperature = approximately +32°F (0°C) then the adjusted air pressure = specified air pressure +3 psi (+0.2 bar).

Tire pressures listed for light loads are minimum values offering high driving comfort. Increased inflation pressures for heavy loads produce favorable handling characteristics with lighter loads and are perfectly permissible. The ride of the vehicle, however, will become somewhat harder. Tire temperature and pressure increase with the vehicle speed. Tire pressure should therefore only be checked and corrected on cold tires. Correct tire pressure in warm tires only if pressure has dropped below the pressure listed in the table and the respective operating conditions are taken into consideration. An underinflated tire due to a slow leak (e.g. due to a nail in the tire) may cause damage such as tread separation, bulging etc.. Regular tire pressure checks (including the spare tire) at intervals of no more than 14 days are therefore essential.

If a tire constantly loses air, it should be inspected for damage. The spare tire should be checked periodically for condition and inflation. Spare tire will age and become worn over time even if never used, and thus should be inspected and replaced when necessary.

Warning! Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.. Follow recommended inflation pressures. Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the driver’s door latch post). Overloading the tires can overheat them, possibly causing a blowout.

Battery

Warning! Failure to follow these instructions can result in severe injury or death. Never lean over batteries while connecting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc..

Important! Battery replacement information: The maintenance-free battery is located in the engine compartment. The service life of the battery is dependent on its condition of charge. The battery should always be kept sufficiently charged, in order to last an optimum length of time.

Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for short distance trips, or if it is not used for long periods of time. Only charge a battery with a battery charger after the battery has been disconnected from the vehicle’s electrical circuit. Always disconnect the battery negative lead first and connect last. When removing and connecting the battery, always make sure that all electrical consumers are off and the key is in steering lock position 0. The battery must always be securely installed when the vehicle is in operation. During removal and installation always protect the disconnected battery positive (+) terminal with the cover attached to the battery. While the engine is running the battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components would be damaged.

252

Note: After reconnecting the battery also set the clock in instrument cluster (see page 80), set date in trip computer (see page 83), resynchronize the sliding/pop- up roof (see page 272), the Skyview Top (see page 273) and the electronic stability program (ESP) (see page 206).

Battery recycling Batteries contain material that can harm the environment with improper disposal. Large 12 Volt storage batteries contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

Jump starting

Warning! Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death. Never lean over batteries while connecting or jump starting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water, and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and very explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc.. Read all instructions before proceeding.

Important! A discharged battery can freeze at approximately +14°F (–10°C). In that case, it must be thawed out before jumper cables are used. Attempting to jump start a frozen battery can result in it exploding, causing personal injury. Jumper cable specifications: • Minimum cable cross-section of 25 mm2 or

approximately 2 AWG

• Maximum length of 11.5 ft. (3.5 m). If the battery is discharged, the engine should be started with jumper cables and the (12 V) battery of another vehicle. Only use 12 V battery to jump start your vehicle. Jump starting with more powerful battery could damage the vehicle’s electrical systems, which will not be covered by the Mercedes-Benz Limited Warranty. The battery is located in the engine compartment.

Proceed as follows:

1. Position the vehicle with the charged battery so that

the jumper cables will reach, but never let the vehicles touch. Make sure the jumper cables do not have loose or missing insulation.

2. On both vehicles:

• Turn off engine and all lights and accessories, except hazard warning flashers or work lights. • Apply parking brake and shift selector lever to

position “P”.

Important!

3. Clamp one end of the first jumper cable to the

positive (+) under hood terminal of the discharged battery and the other end to the positive (+) terminal of the charged battery. Make sure the cable clamps do not touch any other metal parts.

4. Clamp one end of the second jumper cable to the

grounded negative (–) terminal of the charged battery and the final connection to the negative (–) terminal of the discharged battery.

254

Important!

5. Start engine of the vehicle with the charged battery

and run at high idle. Make sure the cables are not on or near pulleys, fans, or other parts that move when the engine is started. Allow the discharged battery to charge for a few minutes. Start engine of the disabled vehicle in the usual manner.

6. After the engine has started, remove jumper cables

by exactly reversing the above installation sequence, starting with the last connection made first. When removing each clamp, make sure that it does not touch any other metal while the other end is still attached.

Notes: If engine does not run after several unsuccessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Light Truck Center. Excessive unburned fuel may damage the catalytic converter.

Towing the vehicle

Prior to towing the vehicle with all wheels on the ground, make certain that the key is in steering lock position 2.

Important! When towing the vehicle, please, note the following: With the automatic central locking activated and the engine running, the vehicle doors lock if the left front wheel is turning at vehicle speeds of approximately 9 mph (15 km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking, see page 32.

To be certain to avoid additional damage to the vehicle powertrain, however you should do the following: • With damage to front axle, raise front axle. Remove flexible drive shaft between rear axle and transfer case

• With damage to rear axle, raise rear axle and tow vehicle with wheel lift or dolly placed under front wheels.

• With damage to transfer case, remove flexible drive

shafts to the drive axles.

Note: Always install new self-locking nuts when reinstalling the flexible drive shaft.

258

Caution! If the vehicle is towed with the front axle raised, the engine must be shut off (key in steering lock position 1). Otherwise, the 4-ETS+ may become engaged which may cause loss of towing control. Switch off the tow-away alarm (see page 36) as well as the ESP (see page 207).

Warning! With the engine not running, there is no power assistance for the braking and steering systems. In this case, it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer the vehicle.

Note: To signal turns while being towed with hazard warning flasher in use, turn key in steering lock to position 2 and activate combination switch for left or right turn signal in usual manner. Now deactivate the hazard warning flasher, only the selected turn signal will operate. Upon canceling the turn signal, the hazard warning flasher must be activated again.

Transmission selector lever, manually unlocking

Stranded vehicle Freeing a stranded vehicle, on which the wheels are dug into sand or mud, should be done with the greatest of care, especially if the vehicle is heavily loaded. Avoid pulling the vehicle jerkily or diagonally, since it could result in damage to the chassis alignment. Never try to free a vehicle that is still coupled to a trailer. If possible, a vehicle equipped with trailer hitch receiver should be pulled backward in its own previously made tracks.

In the case of power failure the transmission selector lever can be manually unlocked, e.g. to tow the vehicle. To do so, insert a pin (1), e.g. ball point pen, into the covered opening below the position “D” of the shift pattern. While pushing the pin down, move selector lever from position “P”. After removal of the pin from the opening, the cover will not close fully. Only after moving the selector lever to positions “D+” and “D–” does the cover return to its closed position.

Adjusting headlamp aim

low beam

Correct headlamp adjustment is extremely important. To check and readjust a headlamp, follow steps 1 through 7. Please note: • High beam adjustments simultaneously aim the low

beam.

• Vehicle should have a normal trunk load.

268

1. Park vehicle on level surface approximately 6 inches

(152 mm) from a vertical test screen or wall. The centerline of the vehicle must be at a 90° angle to the test screen.

2. (High beams on):

Using a carpenter’s level, align and mark a vertical centerline (1) on the test screen for each headlamp lens at a distance of 25 3/4 inches (654 mm) from the vertical centerline. As a check, the distance between centerlines should be 51 1/2 inches (1308 mm). The star emblem on the hood may be used to determine the vehicle centerline. If the distance does not check, have the system verified at an authorized Mercedes-Benz Light Truck Center. 3. Move vehicle on the level surface 25 feet (7.6 m)

straight back from the wall.

4. Open hood.

7. For proper aim, the indicator (8 on page 261) should align with the “0” mark after horizontal adjustment. Graduations: 0.33° pitch.

Note: If it is not possible to obtain a proper headlamp adjustment, have the system checked at your authorized Mercedes-Benz Light Truck Center.

5. (High beams on):

Simultaneously turn adjusting screws (1 and 2 on page 261 or 262) counterclockwise to adjust headlamp downward, clockwise upward) equally until bubble in the level (7 on page 261) is centered on the “0” mark. Graduations: screw 1: 0.50° pitch, screw 2: 0.67° pitch.

6. Horizontal headlamp aim (High beams on):

Turn adjusting screw (2) (left headlamp: counterclockwise to adjust to the left, clockwise to the right [right headlamp in opposite direction]) until the headlamp (high beam pattern) is centered about the vertical centerline (1) as shown. The left and right headlamps must be adjusted individually.
