Practical hints Towing the vehicle ! 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, or KEYLESS-GO* start/stop button in 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 ( page 85). To prevent the vehicle doors from locking, deactivate the automatic central locking ( page 106). 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.
