system.
Anti-theft alarm (DWA). This is a
dealer-installed option for which the
E46 vehicles are factory-wired. When
armed, the system monitors door lock
contacts and trunk and engine hood
locks and sounds a siren if it detects
tampering.
Tilt sensor. Located in the right side of
the trunk above the battery, the tilt
sensor monitors the vehicle parked
angle when DWA is armed. The siren is
activated if the vehicle angle is
changed. This helps prevent theft of
the car using a ramp truck.
Ultrasonic interior protection (UIS). An
interior ultrasonic emitter/detector is
installed in the center of the headliner
of Sedan, Coupe and Sport Wagon
models. The DWA alarm is triggered if
motion is detected inside the car.
Short distance radar (SDR) is the
interior motion detector system used in
Convertible models. The SDR emitter is
located on the driveshaft tunnel under
the center console next to the parking
brake.

systems, see 515 Central Locking
and Anti-theft.

Emergency location

If emergency assistance is needed, the
on-board navigation system (if
equipped) uses GPS technology to
pinpoint the location of the vehicle.
