The anti-theft alarm system increases the level of protection against people

signals if an attempt is made to break into the vehicle (hereafter referred to only
as alarm).
An alarm is triggered when the following monitored areas of the vehicle have a
fault.
› Bonnet.
› Boot lid.
› Doors.
› Ignition lock.
› Vehicle inclination
» page 39.
› Interior of car
» page 39.
› A drop in voltage of the on-board power supply.
› Socket of the factory-fitted towing device
» page 162, Towing a trailer .
An alarm is immediately triggered if either of the two battery terminals is discon-
nected while the anti-theft alarm system is activated.
The alarm is switched off by unlocking the vehicle or switching on the ignition.
CAUTION
Before leaving the vehicle, it must be checked that all of the doors and windows
including the sliding/tilting roof are locked in order to ensure the full functionality
of the anti-theft alarm system.
Note
The working life of the alarm siren is 5 years.
