Central locking system Opening and closing Ð from outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and re-
leases the locks on the
>doors,
>luggage compartment lid and
>fuel filler door.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
Activating it from inside does not lock
the fuel filler door (see page 38). When
the system is actuated from the out-
side, the antitheft system is activated
simultaneously. Both the door locks
and the safety lock buttons remain
locked. The alarm system
* is also
armed or disarmed.
If locked from the inside, the central
locking system unlocks automatically in
the event of an accident. In addition,
the hazard warning flashers and interior
lamps come on.
Using the keyOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
the passenger-side door, the luggage
compartment lid and the fuel filler door.
You can have a confirmation mes-
sage set to inform you that the car
has been properly locked.<
You will find additional information on
the alarm system
* on page 42.

dows and sliding/tilt sunroof

>To open: With the door closed, turn
the key to the "Unlock" position and

Watch during the closing process
to be sure that no one is injured.
Releasing the key stops the opera-
tion.<

Luggage compartment lidOpening from the insideIf the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is sta-
tionary.460de011
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage com-
partment lid is clear when it is closed,
as with all closing procedures.<460de067
Operate the vehicle only when the
luggage compartment lid is com-
pletely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle. Should it be absolutely nec-
essary to operate the vehicle with the
luggage compartment lid open:
>Close all windows. Shut the sliding/
tilt sunroof
*.
>Increase the airflow of the automatic
climate control to a high level. Refer
to page 86.<

Alarm system
*
>If the indicator lamp flashes for
10 seconds when the system is dis-
armed: An attempted entry has been
detected in the period since the sys-
tem was armed.
Following triggering of an alarm, the in-
dicator lamp will flash continuously.Avoiding an unintentional alarmThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages
with elevator ramps, for instance), or
when the vehicle is transported by
trailer or train:
Lock the vehicle twice (= arm the sys-
tem). Press button 2 on the remote con-
trol twice in succession or lock the
vehicle twice with the key (refer to
page 36).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's roof.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
However, you should switch off the inte-
rior motion sensor (see previous column
under the heading "Avoiding an unin-
tentional alarm") if you wish to leave the
windows or sliding/tilt sunroof open.460de159
The tilt sensor and interior motion
sensor are deactivated if the con-
venience closing mode for the windows
and the sliding/tilt sunroof is interrupted
within the first 10 seconds and then
reinitiated. If this happens, you must
disarm the system and then re-arm it.<

Electric power windows Sliding/Tilt sunroof
*
Safety switch You can use the safety switch to deacti-
vate the rear power window switches
(when children are in the rear seats, for
instance).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.<460de014
Exercise care when closing the
sliding/tilt sunroof and keep it in
your field of vision until it is completely
closed. Failure to do so can result in
injuries.
Remove the key from the ignition and
close the doors when you leave the ve-
hicle so that children cannot operate
the sunroof and possibly injure them-
selves.<
To avoid pressure or drafts in the pas-
senger compartment when the sunroof
is open or raised, keep the air vents in
the dashboard open and increase the air
supply if necessary. Refer to page 89.
If the sunroof is completely open, air
disturbances may be caused in the
vehicle when you are driving at higher
speeds. Close the roof as far as is nec-
essary until this natural phenomenon
ceases.
For the convenience operating mode
with the door lock or the remote con-
trol, refer to page 34 or 35.

After the ignition has been switched off,
you can still operate the sunroof for up
to 15 minutes, as long as neither of the
front doors has been opened.Automatic opening and closing>Press the switch past the resistance
