Central Locking System
The entire vehicle may be locked
or unlocked with the central
locking system by:
• Using the master or valet key
in either front door.
• Using the master key in the
trunk lock.
• Pushing down or pulling up the
interior door lock button at
either front door.
The central locking system locks
or unlocks all doors, trunk lid and
fuel filler flap simultaneously.
Doors
When you lock the car, all door
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.
The central locking system can be
engaged from the driver's door
lock button, provided the door-
is completely closed. It can also
be engaged from the front pas­
senger door if the ignition key is
removed, or the key is inserted in
the steering lock without having
been turned (key in position 0).
If the car has been locked from
the outside , the anti-theft alarm (if
so equipped) will come on if a
door is opened from the inside.
Trunk
To unlock the trunk with the
central locking system, turn the
master key in the trunk lock
completely to the left and let it
return to the vertical position.
Push in trunk lock button and
open the trunk. To lock the trunk,
turn the master key completely to
the right and let it return to the
vertical position.
The trunk can remain locked while
the central locking system is
unlocked (e.g. while driving or
when leaving the car in a situa­
tion where it must be driven using
the valet key, but you wish the
trunk to remain locked at parking
lots, workshops, etc.). Turn the
master key completely to the right
and pull it out in the horizontal
position. Now the trunk can only
be unlocked with the master key
by turning it back completely to
the left.
Sliding/Pop-Up Roof and Side
Windows (Power Windows)
Turn key in door lock or trunk lock
to the locking position and hold.
The windows and the sliding/
pop-up roof begin to close
automatically after approx.
1 second.
Warning!
Never close the windows or
sliding/pop-up roof if there is
danger of anyone being
harmed by the closing proce­
dure.
In case of danger, the closing
procedure can be immediately
interrupted by turning the key
back to the vertical position.
