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
>Fuel filler door
>Glove compartment
>Storage shelf for the cellular phone.
The central locking system can be
operated:
>From outside via the driver's door
lock, or by using the remote control
>From inside by pressing a button.
If you initiate central locking from in-
side, neither the fuel filler door, glove
compartment, nor the storage shelf for
the cellular phone are locked (refer to
page 34).
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.
If locked from 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 keySwing the cover panel for the door lock
upward. After either locking or unlock-
ing, return it to its original position until
it clicks back into its final position.
Turning the key in the driver's door
once will unlock the driver's door only;
turning the key a second time will un-
lock the passenger door, the luggage
compartment lid, fuel filler door, the
glove compartment, and the storage
shelf for the cellular phone.
If necessary, you can open the fuel filler
door by pressing the respective button
inside the vehicle; refer to page 23.
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.
Watch during the closing process
to be sure that no one is inadvert-
ently injured. Releasing the key stops
the operation.
Turn the key all the way to the extreme
left or right to unlock/lock the driver's
door.
Refer to page 141 for operating the
passenger-side door.

closed while driving so that no exhaust
fumes penetrate inside the vehicle. If,
however, the luggage compartment lid
has to stay open and the convertible
top is closed while driving,

ing and ventilation system to a high

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
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 vehi-
cle is transported by trailer or train:
Lock the vehicle twice (= arm the sys-
tem) by pressing button 2 on the re-
mote control twice in succession (refer
to page 32), or lock the vehicle twice
with the key (refer to page 30).
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 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 re-
ceived FCC (Federal Communications
Comission) approval.<
