Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed.
The system simultaneously engages and 
releases the locks on the following:
>Doors
>Luggage compartment lid or tailgate and 
rear window
>Fuel filler door
Operating from outside
>via the remote control
>via the door lock
>with comfort access
* via the door handles
At the same time, the anti-theft system is also 
operated. It prevents the doors from being 
unlocked using the lock buttons or door han-
dles. In addition, it the remote control is used, 
the welcome lamps, the interior lamps and the 
courtesy lamps
* are switched on or off. The 
alarm system
 is armed/disarmed at the same 
time.
You can find more detailed information on the 
alarm system
 on page37.
Operating from inside
Via the button for central locking, refer to 
page33. The fuel filler door is not locked.
In the event of a sufficiently severe accident, the 
central locking system unlocks automatically. In 
addition, the hazard warning flashers and inte-
rior lamps come on.

parked vehicle can lock the doors from 
the inside. Always take along the remote control 
when leaving the vehicle so that the vehicle can 
then be opened from the outside.<
