Alarm system
*
>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.
Avoiding an unintentional alarm The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages
with elevator ramps, for instance), or
when the vehicle is transported by
trailer or train:
Locking the vehicle twice (= arming the
system). Press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key. Refer to
page 34.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Reset the alarm to reactivate the tilt
alarm sensor and the interior motion
sensor.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's roof.
For the interior motion sensor to func-
tion properly, the windows and sliding/
tilt sunroof must be closed.
However, you should switch off the
interior motion sensor (see previous
column) if you wish to leave the
windows or sliding/tilt sunroof open.460de159

The conceptThe PDC assists you when you back
into a parking space. A signal warns
you of the distance to an obstacle. To
do this, four ultrasonic sensors in the
rear bumper measure the distance to
the nearest object. The range for the
sensors located at both rear corners
ends approx. 2 ft (60 cm) behind the
bumpers. The range for the two middle
sensors is slightly less than 4.9 ft
(1.50 meters).
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in posi-
tion 2. PDC is deactivated when you
shift back out of reverse.
Acoustical signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the
intervals between the tones become
shorter. A continuous tone indicates
the presence of an object less than 1 ft
(30 cm) away.
The warning signal is canceled after
approx. three seconds if the distance to
the obstacle remains constant during
this time (if you are moving parallel to
a wall, for instance).
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please refer the problem to your
BMW center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical limits of ultra-
sonic measurement, as occurs with tow
bars and trailer couplings, and in the
vicinity of thin and painted objects.
Certain sources of sound, such as a
loud radio, could drown the PDC signal
tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not subject the sensors to high-
pressure washers for a prolonged
period of time. Always maintain a
distance of more than 4 in (10 cm).<
