The central locking system locks or
unlocks all doors, tru n k lid and fuel
filler flap simultaneously.
Doors
When you lock the car, all d oor lock
buttons should move down. If any one
stays up, the respective door is not
properly closed. You should then
unlock the car, open and reclose this
door, and lock the car again.
Note:
The central locking system can be
engaged from the driver-side door
lock button, provided the d oor is
com pletely closed. It can also be
engaged from the passenger-side if
the ignition key is removed, or
engaged in the steering lock w ithout
being turned (key in position 0).
If the car has been locked from the
outside with the m aster key, the anti­
theft alarm will come on if a door is
opened from the inside, or if opened
with the valet key.
Trunk
To unlock the tru nk with the central
locking system, turn the m aster key in
the trunk lock com pletely to the left
and let it return to the normal posi­
tion. Push in tru n k lock button and
open the trunk. To lock the trunk, turn
the master key com pletely to the right
and let it return to the normal posi­
tion.
The tru n k can remain locked while the
central locking system is unlocked
(e.g. while driving or when leaving the
car in a situation where it must be
driven using the valet key, but you
wish the trunk to remain locked at
parking lots, w orkshops, etc.). Turn
the master key com pletely to the right
and pull it out in that position. Now
the trunk can only be unlocked with
the master key by turning it back to
the left.
