Instruments and controls Operation Driving Instrument cluster display 34 Practical hints Car care Technical data Index Central locking system Automatic central locking With the automatic central locking system activated, the doors and trunk are locked at vehicle speeds of approximately 9 mph (15 km/h) or more. The fuel filler flap remains unlocked. The automatic central locking function can be switched on or off. See page 111 for "Individual settings". Notes: If doors are unlocked with the central locking switch after activating the automatic central locking, and neither door is opened, then the doors remain unlocked even at vehicle speeds of approximately 9 mph (15 km/h) or more. If a door is opened from the inside at speeds of approximately 9 mph (15 km/h) or less with the automatic central locking activated, the door will again be automatically locked at speeds of approximately 9 mph (15 km/h) or more. Important! When towing the vehicle, or with the vehicle on a dynamometer test stand, please, note the following: With the automatic central locking activated and the electronic key in starter switch position 2, the vehicle doors will lock if the left front wheel as well as the right rear wheel spin at vehicle speeds of approximately 9 mph (15 km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking. See page 111 for "Individual settings" - "VEHICLE". Emergency unlocking in case of accident The doors unlock automatically a short time after an accident in which an airbag or emergency tensioning retractor deploys (this is intended to aid rescue and exit).
