>When the car's inclination changes, for 
instance if an attempt is made to jack it up 
and steal the wheels or to raise it prior to 
towing away
>When there has been an interruption of 
power supply from the battery
The alarm system signals unauthorized entry 
attempts for a short time by means of:
>An acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams
