Practical hints Jump starting 왔 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.

326

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 con- verter 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 starting 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 an engine is started or running.

Jump starting may only be performed on the battery installed in the engine compartment. Avoid repeated and lengthy starting attempts. 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 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.

Warning!

Keep flames or sparks away from battery. Do not smoke.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 258).

The battery is located in the engine compartment on the right hand side. The terminals for jump starting are located in front of the battery. 왘 Make sure the two vehicles do not

touch.

You can now again turn on the electrical consumers. Do not turn on the lights under any circumstances. 왘 Remove the jumper cables first from

negative terminals 3 and 4 and then from positive terminals 1 and 2.

You can now turn on the lights. 왘 Have the battery checked at the near- est authorized Mercedes-Benz Center.

Vehicles with automatic transmission and/or 4MATIC: Do not tow-start the vehicle.

327

Practical hints Towing 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 SmartKey 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. Switch off the tow-away alarm (컄 page 79) and deactivate the auto- matic central locking (컄 page 133).

328

When circumstances do not permit the recommended towing methods, the vehicle may be towed with all wheels on the ground or front wheels raised (except vehicles with 4MATIC) only so far as necessary to have the vehicle moved to a safe location where the recommended towing methods can be employed.

Vehicles with automatic transmission and/or 4MATIC: Do not tow-start the vehicle.

Vehicles with 4MATIC: Do not tow with one axle raised. Doing so could damage the transfer case, which is not covered by the Mercedes-Benz Limited Warranty. All wheels must be on or off the ground. Observe instructions for towing the vehicle with all wheels on the ground.

If the vehicle is towed with the front axle raised (not permissible for vehicles with 4MATIC), the engine must be shut off (SmartKey in starter switch position 0 or 1). Otherwise the ESP will immediately be engaged and will apply the rear wheel brakes. When towing the vehicle with all wheels on the ground, the gear selector lever must be in position N (manual trans- mission: gears disengaged) and the SmartKey must be in starter switch position 2. When towing the vehicle with all wheels on the ground or the front axle raised, 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).

! To be certain to avoid a possibility of damage to the drive train, however, we recommend the drive shaft be discon- nected at the rear axle drive flange (vehicles with 4MATIC: disconnected at the front and rear axle drive flanges) for any towing beyond a short tow to a nearby garage.

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 supply or in the vehicle’s electrical system

as that will be necessary to adequately control the towed vehicle.

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

If the SmartKey is left in 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, remove SmartKey from starter switch and reinsert.

Practical hints Towing the vehicle

To signal turns while being towed with the hazard warning flasher in use, turn SmartKey in starter switch to position 2 and activate the combina- tion switch for the left or right turn signal in the usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the hazard warning flasher will operate again.

329

Practical hints Towing the vehicle

Warning!

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 ve- hicle. Adapt your driving accordingly.

330

If the battery is disconnected or discharged 앫 the SmartKey will not turn in the starter switch. See notes on the battery (컄 page 323) or on jump starting (컄 page 326).

앫 the gear selector lever will remain locked in position P. See notes on manually unlocking transmission gear selector lever (컄 page 308).

When towing the vehicle with all wheels on the ground, please note the following: With the automatic central locking activated and the SmartKey in starter switch position 2, the vehicle doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approx. 9 mph (15 km/h) or more. Switch off the tow-away alarm (컄 page 79). To prevent the vehicle doors from locking, deactivate the automatic central locking (컄 page 133). Towing of the vehicle should only be done using the properly installed towing eye bolt. Never attach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.
