Alarm system
The concept
The vehicle alarm system responds:
> When a door, the hood or the trunk lid is 
opened
> To movements inside the vehicle: interior 
motion sensor, refer to page 39
> When the car's inclination changes, e.g. 
if an attempt is made to  jack it up and steal 
the wheels or to raise it prior to towing away: 
tilt alarm sensor, refer to page 39
