The anti-theft alarm system (hereinafter referred to as the alarm system) in-
creases protection against theft and break-in attempts into the vehicle.
The alarm system is activated automatically approximately 30 seconds after

The alarm system triggers audible and visual signals if an attempt is made to
break into the vehicle (hereafter referred to as alarm).

The alarm is triggered when the following unauthorized actions are carried out
on the locked vehicle.

▶
Opening the doors.
▶
Manipulation of the ignition lock.
▶
Towing the vehicle.
▶
Movement in the vehicle.
▶

If the driver's door of a vehicle is unlocked and opened by the lock cylinder,
then the alarm is triggered.

the ignition.
CAUTION
Before leaving the vehicle, it must be checked that all of the windows, doors
and the sliding/tilting roof are locked in order to ensure the full functionality of
