BMW 7 Series: Introduction
Anti-theft System
The anti-theft system is available as an option. The task of the anti-theft system is to indicate unauthorized access to the vehicle by emitting an alarm. The alarm can be triggered both audibly and visually. To do this, however, the anti-theft system must be activated. When activated, the alarm monitors the whole of the vehicle interior.
In addition the anti-theft system monitors the engine compartment and the vehicle's rest position. In order that nothing can be stolen from the trunk, the anti-theft system monitors opening of the trunk lid.
The alarm also signals an attempt to tamper with the vehicle, e.g. cutting of the supply line to the emergency power siren.
The anti-theft system's ultrasonic interior movement detector is entirely integrated in the roof function center.
The ultrasonic signal passes into the inside of vehicle through apertures in the grille of the roof function center.
The emergency power siren and combined tilt sensor is located near the rear wheel arch.
