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.
