Upon canceling the turn signal, the hazard warning flasher will operate again. ! When towing the vehicle with all wheels on the ground, note the following: With the automatic central locking activated and the key in starter switch position 2, the vehicle doors lock if the wheels are 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 ( page 128). 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. With the engine not running, there is no power assistance for the braking 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. i The selector lever will remain locked in position P and the key will not turn in the starter switch if the battery is disconnected or discharged.
