Practical hints Towing the vehicle 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. 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 automatic transmission must be in position N and the SmartKey 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 the front axle raised (observe instructions regarding flexible drive shaft), the engine must be shut off (SmartKey in starter switch position 1). Otherwise, the 4-ETS may become engaged which may cause loss of towing control. ! Use flatbed or wheel lift/dolly equipment, with the 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. Use the towing eyes. Switch off the ESP® ( page 101), tow-away alarm ( page 107) and the automatic central locking ( page 130). Do not tow-start the vehicle. ! 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 vehicles with all wheels on the ground. 499
