Alarm indicator

A red LED on the instrument panel indicates the alarm system's status:

LED not lit – alarm not armed.
The LED flashes once every other second – alarm is armed.
After the alarm has been disarmed, the LED flashes rapidly for a maximum of 30 seconds or until ignition position I has been activated - the alarm has been triggered.

When armed, the alarm is triggered if:

a door, the bonnet or the tailgate is opened^[1]
a movement is detected in the passenger compartment (if fitted with a movement detector^*)
the car is raised or towed away (if fitted with a tilt detector^*)
the battery is disconnected
the siren is disconnected.

When the alarm has been triggered, the following happens:

If the cause of alarm activation is not rectified, the alarm cycle is repeated up to 10 times^[1].

Movement and tilt detectors react to movements inside the car^[2] e.g. if the window is broken or if anyone tries to tow the car away.

To avoid triggering the alarm unintentionally:

Close all windows when leaving the car.
Close the panoramic roof.
If the climate control is used – aim the airflow so that it does not point upwards in the passenger compartment.

It is also possible to reduce the alarm level in the centre display.
