Automatic central locking
The central locking switch also operates the automatic 
central locking.
With the automatic central locking system activated, the 
doors and trunk are locked at vehicle speeds of approx. 
9 mph (15 km/h) or more. The fuel filler flap remains 
unlocked.
To activate:
With key in steering lock position 2 hold upper portion 
of switch (1) for a minimum of 5 seconds.
To deactivate:
With key in steering lock position 2 hold lower portion 
of switch (2) for a minimum of 5 seconds.
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 approx. 9 mph (15 km/h) or 
more.
If a door is opened from the inside at speeds of approx. 
9 mph (15 km/h) or less with the automatic central 
locking activated, the door will again be automatically 
locked at speeds of approx. 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 
key in steering lock position 2, the vehicle doors will 
lock if the left front wheel as well as the right rear 
wheel spin 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.
Emergency unlocking in case of accident
The doors unlock automatically a short time after a 
strong deceleration is detected, such as in a collision 
(this is intended to aid rescue and exit). Driving on 
rough roads may cause the vehicle to unlock. If 
necessary, the vehicle can be locked again with the 
interior central locking switch.
