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 approx. 9 mph (15 km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking ( page 112). 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 the vehicle chassis, frame or suspension parts. i If the battery is disconnected or discharged the SmartKey will not turn in the starter switch the gear selector lever will remain locked in position P.
