Central door locking
By means of the central door locking system
both doors are electrically locked or unlocked
by operating one lock.
When the doors are locked the locking but-
tons (A) must be fully retracted. If this is not
the case the lock on that door is not properly
engaged. Re-open the door, close it properly
and re-lock it.
On vehicles with central locking the passenger
door can be locked and unlocked by turning
the knob (B) as well as with the key.
To prevent being accidentally locked out of
the vehicle it is impossible to lock the door,
while open, either using the knob (B) or with
the key.
Central locking is only possible when both
driver and passenger doors are closed. If
one door is locked before the other is closed
it will automatically unlock when the other door
is closed.
When the ignition has been switched on or
when the ignition key is turned to position 1,
both doors can be electrically locked or un-
locked by pressing the central locking button
in the center console. The lamp in the central
door locking button remains lit whilst the sys-
tem is activated.
When the ignition is switched off but with the
key still in the ignition lock the doors can be
centrally locked using either the key or the
knob (B).
Door guard lights
The door guard lights come on when a door
or the luggage compartment door is opened.
