The PDC assists you when you are
parking. A signal warns you of the real
distance to an obstacle. To do this, four
ultrasonic sensors in the rear bumper
measure the distance from the nearest
object. The monitoring range for the
two corner sensors ends approx. 2 feet
(60 cm) beyond the respective bumper.
The range of the two middle sensors is
approx. 4.9 feet (1.50 meters) outward.
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in posi-
tion 2. It is similarly deactivated when
you engage reverse gear or move the
selector lever position from the "R" po-
sition.
Acoustical signalsThe distance to the nearest object is in-
dicated by a tone sounding at various
intervals. As the distance between vehi-
cle 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 will be canceled af-
ter approx. 3 seconds if the distance to
the obstruction 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 the cause checked
and corrected by your authorized BMW
center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the ve-
hicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be de-
tected. This applies especially in those
cases where the system approaches
the physical limits of ultrasonic mea-
surement, 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 effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than approx. 4 inches (10 cm).<
