Citroen C4: Alarm

(Depending on version)

Exterior perimeter monitoring

The system checks for opening of the vehicle.

The alarm is triggered if anyone tries to open a door, the boot or the bonnet, for example.

Interior volumetric monitoring

The system checks for any variation in volume in the passenger compartment.

The alarm is triggered if anyone breaks a window, enters the passenger compartment or moves inside the vehicle.

Self-protection function

The system checks whether any of its components are out of service.

The alarm is triggered if the battery, the central control or the siren wiring is put out of service or damaged.
