Park Distance Control (Pdc) - BMW SERIE 3 COUPE 2001 Manual

Park Distance Control (PDC)

The concept
The 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 signals
The 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
