If the alarm system is armed, a visual and
audible alarm is triggered by the following:
R Unlocking the vehicle from inside
R Opening a door
R Opening the hood
i The alarm is not switched off, even if you
immediately close the open door that has
triggered it, for example.
X To stop the alarm: press the0036button
on the remote control.
Or
X Insert the key into the ignition lock.
The alarm stops. Tow-away alarm
Operation A visual and audible alarm is triggered if the
inclination of the vehicle changes when the
tow-away alarm is armed. This can be the
case if the vehicle is raised on one side, for
example.
Arming/deactivating The tow-away alarm is automatically armed
approximately 20 seconds after you lock the
vehicle.
The tow-away alarm is automatically deacti-
vated when you unlock the vehicle.
Deactivating X
Remove the key from the ignition lock.
X Press button 0043.
When the button is released, the indicator
lamp on button 0044lights up for about
5 seconds.
X Lock the vehicle.
The tow-away alarm is deactivated.
The tow-away alarm remains deactivated
until you lock the vehicle again.
Deactivate the tow-away alarm when locking
your vehicle and:
R loading and/or transporting the vehicle, on
a ferry or car transporter, for example
R parking on a moving surface, as split-level
garage
This will prevent false alarms. Interior motion sensor
Operation If the armed interior motion sensor detects
motion in the vehicle interior, a visual and
acoustic alarm is triggered. This can happen
if someone reaches into the vehicle interior,
for example.
i
If the interior motion sensor is armed and
the auxiliary heating system (Y page 122)
switches on, a false alarm may occur as a
result of interior temperature monitoring.
In this case, either deactivate the interior
motion sensor or switch off the auxiliary
heating.
Arming X
Close the side windows.
X Make sure that nothing (such as mascots
or coat hangers) are hanging on the rear-
view mirror or on the grab handles on the
headliner.
This will prevent false alarms.
X Lock the vehicle.
The interior motion sensor is armed after
approximately 40 seconds. Theft deterrent locking system
