Practical hints Battery

Use leak-proof battery only to avoid the risk of acid burns in the event of an accident.

Batteries contain materials that can harm the environment if disposed of improperly. 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.

Failure to follow these instructions can re- sult in severe injury or death.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 223). 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.

Never charge a battery while still installed in the vehicle. Gases may escape during charg- ing and cause explosions that may result in paint damage, corrosion or personal injury.

Have the battery removed at a Mercedes-Benz Light Truck Center.

Have the battery checked regularly by an authorized Mercedes-Benz Light Truck Center. Refer to Service Booklet for mainte- nance intervals or contact your autho- rized Mercedes-Benz Light Truck Center for further information.

If you charge the battery yourself, make sure to comply with the operating instruc- tions for your battery charger.

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.

Attempting to jump start a frozen battery can result in it exploding, causing personal injury.

Read all instructions before proceeding.

If the battery is discharged, the engine can be started with jumper cables and the bat- tery of another vehicle. Observe the follow- ing: 앫 Jump starting should only be performed when the engine and catalytic convert- er are cold.

앫 Do not start the engine if the battery is

frozen. Let the battery thaw out first. 앫 Only use 12 V battery to jump start

your vehicle. Jump starting with a more powerful battery could damage the ve- hicle’s electrical system, which will not be covered by the Mercedes-Benz Lim- ited Warranty.

앫 Use only jumper cables with sufficient

cross-section and insulated terminal clamps.

앫 Always make sure that the jumper ca- bles are not on or near pulleys, fans, or other parts that move when an engine is started or running.

Practical hints Jump starting

Avoid repeated and lengthy starting at- tempts. Do not attempt to start the engine us- ing a battery quick charge unit. If engine does not run after several un- successful starting attempts, have it checked at the nearest authorized Mercedes-Benz Light Truck Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the catalytic converter and may present a fire risk. Make sure the jumper cables do not have loose or missing insulation. Make sure the cable clamps do not touch any other metal part while the other end is still attached to a battery.

Do not tow-start the vehicle.

Towing the vehicle Mercedes-Benz recommends that the vehi- cle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment. This method is pref- erable to other types of towing.

Use flatbed or wheel lift/dolly equip- ment, with key in starter switch turned to position 0. Do not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports. To prevent damage during transport, do not tie down vehicle by its chassis or suspension parts. Use the towing eyes. Switch off the ESP (컄 page 76), tow-away alarm (컄 page 80) and the automatic central locking (컄 page 128).

When circumstances do not permit the recommended towing methods, the vehi- cle may be towed with all wheels on the

ground only so far as necessary to have the vehicle moved to a safe location where the recommended towing methods can be em- ployed.

When towing the vehicle with all wheels on the ground, the selector lever must be in position N and the key must be in starter switch position 2. When towing the vehicle with all wheels on the ground, the vehicle may be towed only for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). If the vehicle is towed with one axle raised (observe instructions regarding flexible drive shaft and propeller shafts), the engine must be shut off (key in starter switch position 1). Oth- erwise, the 4-ETS may become en- gaged which may cause loss of towing control.

Practical hints Towing the vehicle

Do not tow-start the vehicle.

Warning!

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

If the key is left in the starter switch position 0 for an extended period of time, it can no longer be turned in the switch. In this case, the steering is locked. To unlock, re- move key from starter switch and reinsert.

Always tow with a tow bar if: 앫 the engine will not run 앫 there is a malfunction in the power sup- ply or in the vehicle’s electrical system as that will be necessary to adequately con- trol the towed vehicle.

299

i To signal turns while being towed with hazard warning flasher in use, turn key in starter switch to position 2 and acti- vate combination switch for left or right turn signal in usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the haz- ard warning flasher will operate again.

When towing the vehicle with all wheels on the ground, note the following: With the automatic central locking acti- vated and the key in starter switch position 2, the vehicle doors lock if the wheels are turning at vehicle speeds of approx. 9 mph (15 km/h) or more. To prevent the vehicle doors from lock- ing, deactivate the automatic central locking (컄 page 128). Towing of the vehicle should only be done using the towing eye. Never at- tach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.

Practical hints Towing the vehicle

Warning!

With the engine not running, there is no power assistance for the braking and steer- ing systems. In this case, it is important to keep in mind that a considerably higher de- gree of effort is necessary to brake and steer the vehicle. Adapt your driving accord- ingly.

The selector lever will remain locked in position P and the key will not turn in the starter switch if the battery is dis- connected or discharged. See notes on the battery (컄 page 295) or on jump starting (컄 page 297). Manually unlocking of transmission se- lector lever (컄 page 275).

Transporting the vehicle

Towing the vehicle with various faults

When transporting the vehicle, you can use the towing eyes for pulling the vehicle onto a trailer or transporter. 왘 Move the gear selector lever to posi-

tion N.

왘 Shift the transfer case to neutral posi-

tion N.

왘 To avoid damaging the vehicle, it should only be tied down on the wheels/wheel rims, not on chassis components such as the transverse link or trailing arm.

When removing drive shaft, place M10 nuts on bolts as distance sleeves and tighten using M8 nuts. Always install new self-locking nuts when reinstalling the drive shaft.

왘 Comply with all towing information

(컄 page 299).

In case of engine damage, transmission damage or malfunctions in electrical equipment 왘 Move the gear selector lever to posi-

tion N.

왘 Shift the transfer case to neutral posi-

tion N.

Practical hints Towing the vehicle

In case of transfer case damage or for towing vehicle distances exceeding 30 miles (50 km) The propeller shafts to the drive axles must be removed.

In case of front axle damage Raise the front axle when towing. The pro- peller shaft between the rear axle and the transfer case must be removed.

In case of rear axle damage When the rear axle is raised, the vehicle can only be towed with a wheel lift or a dol- ly placed under its front wheels.

Freeing a stranded vehicle

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

In the front, the towing eye is located on the driver’s side under the bumper.

In the rear, the towing eye is located on the driver’s side under the bumper.
