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 battery of another vehicle. Observe the following: 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 jump start from batteries with the same voltage rating (12 V). Jump start- ing with a more powerful battery could damage the vehicle’s electrical system, which will not be covered by the Mercedes-Benz Limited Warranty.

앫 Only use jumper cables with sufficient

cross-section and insulated terminal clamps.

앫 Always make sure the jumper cables are not on or near pulleys, fans, or oth- er parts that move when the engine is started or running.

Practical hints Jump starting

Avoid repeated and lengthy starting at- tempts. Do not attempt to start the engine using a battery quick charge unit. 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 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.

You can now turn on the lights. 왘 Have the battery checked at the

nearest authorized Mercedes-Benz Light Truck Center.

Do not tow-start the vehicle.

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

Use flatbed or wheel lift/dolly equip- ment, with key in steering lock 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 81), tow-away alarm (컄 page 85) and the automatic central locking (컄 page 93).

When circumstances do not permit the recommended towing methods, the vehicle 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 employed.

When towing the vehicle with all wheels on the ground, the gear selector lever must be in position N and the key must be in steering lock 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 the front axle raised (observe instructions re- garding flexible drive shaft), 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.

Practical hints Towing the vehicle

To be certain to avoid additional dam- age to the vehicle powertrain, however you should observe the following: 앫 With damage to the front axle

앫 raise front axle 앫 remove flexible drive shaft be- tween rear axle and transfer case

앫 With damage to the rear axle

앫 raise rear axle 앫 tow vehicle with wheel lift or

dolly placed under front wheels 앫 With damage to the transfer case 앫 remove flexible drive shaft to

the drive axles

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

Warning!

Warning!

If circumstances require towing the vehicle with all wheels on the ground, 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 Prior to towing the vehicle with all wheels on the ground, make sure the key is in steering lock position 2.

If the key is left in steering lock 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, remove key from steering lock and reinsert.

With the engine not running, there is no power assistance for the brake 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. Adapt your driving accordingly.

To signal turns while being towed with hazard warning flasher in use, turn key in steering lock 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 hazard warning flasher will operate again.

The vehicle cannot be started via tow-start.

If the battery is disconnected or dis- charged, the gear selector lever will re- main locked in position P and the key will not turn in the steering lock. For more information, see “Battery” (컄 page 272) and “Jump starting” (컄 page 291). For information on manual unlocking transmission gear selector lever, see (컄 page 270).

294

! When towing the vehicle with all wheels on the ground, note the following: With the automatic central locking activated and the key in steering lock position 2, the vehicle doors lock if the left front wheel is turning at vehicle speeds of approx. 9 mph (15 km/h) or more. To prevent the vehicle doors from locking, deactivate the automatic central locking (컄 page 93). Towing of the vehicle should only be done using the towing eye. Never attach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.
