Central locking system Opening and closing Ð from the outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door
>glove compartment
>cellular phone holder.
The central locking system can be
operated
>from the outside via the driver's door
lock or by using the remote control
>from the inside by pressing a button.
If you initiate central locking from
inside, neither the fuel filler door, the
glove compartment, nor the cellular
phone holder are locked (refer to
page 36).
If you do set it from outside, the anti-
theft alarm is automatically activated as
well. This prevents the door handles
from unlocking the doors. The alarm
system is also activated or deactivated.
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.
Using the keySwing the door lock mechanism's cover
upward. Return it to its original position
and allow the detent to engage when
you have finished locking or unlocking
the doors.
Turn the key in the driver's door once to
unlock the driver's door only; turning
the key a second time will unlock the
passenger door, the luggage compart-
ment lid, the fuel filler door, the glove
compartment, and the cellular phone
holder.
If necessary, you can open the fuel filler
door by pressing the button inside the
vehicle; refer to page 25.520de100
You can have various signals set
as an acknowledgment message
when locking.<
Convenience operationYou can also operate the windows via
the door lock.
>To open: with the door closed, turn
the key to the "Unlock" position and
hold it
>To close: with the door closed, turn
the key to the "Lock" position and
hold it.
As the windows are closing you
should always monitor their path
and progress to ensure that no injuries
occur. Release the key to stop the
windows.
Turn the key to the extreme left or right
to unlock/lock the driver's door.
Refer to page 143 for operating the
passenger door.

Luggage compartment lidTo unlock from the insidePress on the upper half of the button
(luggage compartment lid symbol).
The luggage compartment lid opens
slightly.
This button will not open the
luggage compartment lid if the
glove compartment is locked. Refer to
page 78.<520de012
To open from the outsideReach into the recess and open the
luggage compartment lid all the way.
The luggage compartment is illumi-
nated when the lid is opened. Manual operation Should the electrical system malfunc-
tion, the luggage compartment lid can
be opened from the inside. Refer to
page 142. To closeThe luggage compartment is locked
again as soon as you close the lid.520us017
As with all closing procedures, be
sure that the travel path for the
luggage compartment lid is clear when
being closed to avoid injury.
Operate the vehicle only when the
luggage compartment lid is completely
closed. Otherwise exhaust fumes could
penetrate the interior of the vehicle. If,
however, the luggage compartment lid
has to stay open and the convertible
top is closed while driving,
>close all windows
>increase the air supply from the
heating and ventilation system to a
high level. Refer to page 74.<

Alarm systemIndicator lamp displaysThe indicator lamp is located in the
inside rear view mirror's rotary knob.
>The indicator lamp flashes continu-
ously: the system is armed
>The indicator lamp flashes during
arming: a door, the hood or luggage
compartment lid is not completely
closed. Even if you do not respond by
securing the affected area, the system
starts to monitor all other points and
the indicator lamp reverts to contin-
uous, uninterrupted operation once
ten seconds have elapsed. The inte-
rior motion sensor remains off
>The indicator lamp goes out during
disarming: no manipulation or
attempted intrusions have been
detected in the period since the
system was armed520de014
>The indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding unintentional alarms The tilt alarm sensor and interior motion
sensor may be switched off at the same
time 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
system) by pressing button 2 on the
remote control twice in succession
(refer to page 34), or lock the vehicle
twice with the key (refer to page 32).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
remain deactivated for as long as the
system is armed.
Interior motion sensorIn order for the interior motion sensor to
function properly, the windows and the
luggage compartment lid must be
closed.
Nevertheless, you should deactivate
the interior motion sensor (refer to the
previous column) if
>children or animals are left in the
vehicle
>windows should remain open.
For US vehicles only:
The interior motion sensor is not
installed on US models as it has not
received FCC (Federal Communica-
tions Commission) approval.<
