Practical hints 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. Warning! G Warning! G ! Do not tow-start the vehicle. ! Use flatbed or wheel lift/dolly equipment 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 ( page 100) and the automatic central locking ( page 166). If circumstances require towing the vehicle with all wheels on the ground, always tow with a tow bar if: the engine will not run there is a malfunction in the electro-hydraulic brake system there is a malfunction in the power supply or in the vehicle's electrical system This is 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. The brake system requires electrical power to operate. A malfunction in the vehicle's power supply or electrical system may impair brake system operation and switch it into its emergency operation mode. To brake, the driver must then apply significantly greater brake pedal pressure and depress the pedal much further to obtain the expected braking effect. If necessary, apply full pressure to the brake pedal. Brakes are only applied to the front wheels. Stopping distance is increased! Adapt your driving style accordingly. For more information, see "Electro-hydraulic brake system" ( page 94). 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. When circumstances do not permit the recommended towing methods, the vehicle 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. 434
