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
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.
You can have various signals set
as an acknowledgment message
when locking.<520de100
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 141 for operating the
passenger door.

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.
Keep the luggage compartment lid
closed while driving so that no exhaust
fumes will penetrate to the inside of the
vehicle. If, however, the luggage
compartment lid has to stay open and
the convertible top is closed while
driving,
>close all the windows
>increase the air supply from the
heating and ventilation system to a

Alarm system>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 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.<
