The concept
The vehicle alarm system responds to:
► Opening of a door, the hood or the tailgate.
► Movements in the vehicle.
► Changes in the vehicle tilt, e.g., during attempts
to steal a wheel or when towing the
car.
► Interruptions in battery voltage.
The alarm system briefly indicates tampering:
► By sounding an acoustic alarm.
► By switching on the hazard warning system.
► By flashing the high beams.
