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 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 Use only 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 other 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.

Practical hints 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 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 87) and deactivate the auto- matic central locking (컄 page 148).

406

When circumstances do not permit the recommended towing methods, the vehi- cle may be towed with all wheels on the ground or front wheels raised 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: Do not tow-start the vehicle.

If the vehicle is towed with the front axle raised, the engine must be shut off (SmartKey in starter switch position 0 or 1). Otherwise, the ESP will immedi- ately 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 dis- tances 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 transmission, however, we recommend the drive shaft be dis- connected at the rear axle drive flange 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 sup- ply or in the vehicle’s electrical system as that will be necessary to adequately con- trol the towed vehicle.

Prior to towing the vehicle with all wheels on the ground, make sure 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, re- move SmartKey from starter switch and re- insert.

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 sig- nal in the usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the hazard warning flasher will operate again.

407

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.

408

If the battery is disconnected or dis- charged 앫 the SmartKey will not turn in the starter switch. For more informa- tion, see “Battery” (컄 page 401) and “Jump starting” (컄 page 404). 앫 the gear selector lever will remain locked in position P. For informa- tion on manually unlocking trans- mission gear selector lever, see (컄 page 380).

When towing the vehicle with all wheels on the ground, please note the follow- ing: With the automatic central locking acti- vated 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 approximately 9 mph (15 km/h) or more. Switch off the tow-away alarm (컄 page 87). To prevent the vehicle doors from lock- ing, deactivate the automatic central locking (컄 page 148). Towing of the vehicle should only be done using the properly installed tow- ing eye bolt. Never attach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.

왔 Rims and Tires Use only tires and rims which have been specifically developed for your vehicle and tested and approved by Mercedes-Benz. Other tires and rims can have detrimental effects, such as 앫 poor handling characteristics 앫 increased noise 앫 increased fuel consumption

Moreover, tires and rims not approved by Mercedes-Benz may, under load, ex- hibit dimensional variations and differ- ent tire deformation characteristics that could cause them to come into contact with the vehicle body or axle parts. This may result in damage to the tires or the vehicle.

Technical data Rims and Tires

Further information on tires and rims is available at any authorized Mercedes-Benz Center. A placard with the recommended tire inflation pressures is located on the driver’s door B-pillar. Some vehicles may have supplemental tire inflation pressure information for driving at high speeds (컄 page 310) or for vehicle loads less than the maximum loaded vehicle con- dition. If such information is provided, it can be found on the placard located on the inside of the fuel filler flap. The tire inflation pressure should be checked regularly and should only be adjusted on cold tires. Follow tire manufacturer’s maintenance recom- mendation included with vehicle.
