The concept
PDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance to the nearest object. To
do this, four ultrasonic sensors in the
front and rear bumpers each measure
the distance to the nearest object. The
monitoring range of the front sensors
and two rear sensors at the ends of the
rear bumper extends outward roughly
2 ft (60 cm), while the rear bumper's
two centrally located sensors detect
objects at distances of up to approx.
5 ft (1.50 m).
Automatic function
The system is activated automatically
about one second after you engage
reverse with the ignition key in
position 2.
Manual activation
Press the button, the indicator lamp
lights up.
When you subsequently drive a dis-
tance of more than approx. 160 ft
(50 meters) or exceed a speed of
approx. 20 mph (30 km/h), the system
switches off and the indicator lamp
goes out. Switch the system on again
as required.
Manual deactivation
Press the button again.

Acoustic signals
The distance from an obstacle is indi-
cated in front with a higher intermittent
tone, at the rear with a lower intermit-
tent tone. As the distance between
vehicle and object decreases, the inter-
vals between the tones become shorter.
A continuous tone indicates the pres-
ence of an object less than 1 ft (30 cm)
away.
The warning signal is canceled after
approx. three seconds if you are
moving parallel to a wall.
If there is a malfunction of the system:
The indicator lamp flashes and a brief
continuous signal tone is heard
> when you activate PDC with the
button
> when you select reverse for the first
time after switching on the ignition
> if a malfunction occurs while the PDC
system is active.
Switch the system off and have the
cause of the malfunction corrected by
your BMW center.
