Central locking system
The concept
The central locking system functions when the 
driver's door is closed.
The system simultaneously engages and 
releases the locks on the following:
> Doors
> Liftgate
> Fuel filler door
Operating from outside
>via the remote control
> via the door lock
> with comfort access
* via the door handles
The interior lamps and the courtesy lamps
* are 
also switched on and off with the remote con-
trol. The alarm system
 is armed/disarmed at the 
same time.
You can find more detailed information on the 
alarm system
 on page 38.
Operating from inside
Via the button for centra l locking, refer to 
page 32. The fuel filler door is not locked.
In an accident of sufficient severity, the central 
locking system automati cally unlocks the vehi-
cle. In addition, the hazard warning flashers and 
interior lamps come on.
Opening and closing:
Using remote control
Persons or animals left unattended in a 
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. <
