OverviewControlsMaintenanceRepairsDataIndex
The conceptPDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance to an object. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object.The monitoring range for
the two rear sensors extends outward
roughly 2 ft (60 cm). The range for the
two center sensors is approx. 4.9 ft
(1.50 m) wide.
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in
position 2. PDC is deactivated when
you shift back out of reverse.
Acoustic signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the inter-
vals 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 have your BMW center
resolve the problem.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 or wedge-shaped
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 apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in (10 cm).<
