PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones indicate the current distance
to an object behind or in front of your
vehicle. Four ultrasonic sensors in both the
bumpers monitor the distance to the
nearest object. The sensors at the front and
at the two rear corners have a range of
approx. 2 ft (60 cm); the rear middle sen-
sors have approx. 5 ft (1.50 m).
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic function
Whenever the ignition is on the system
automatically assumes operational status
after a few seconds each time you engage
the transmission position R.
Wait this short period before
reversing.<
Switching on manually
Press the button, the indicator lamp lights
up.
Manual deactivation
Press the button again; the indicator lamp
goes out.
Automatic deactivation
The system is automatically deactivated
once the vehicle travels approx. 165 ft
(50 m) or exceeds a speed of roughly
20 mph (30 km/h); the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Acoustic signals
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the
vehicle will be indicated by a signal tone
from the left rear speaker, etc. As the
distance between vehicle and object
decreases, the intervals between the tones
become shorter. The signal tone becomes
continuous once the distance to the
nearest object falls to below roughly 1 ft
(30 cm).
The warning signal is canceled after
approx. 3 seconds when the distance to an
object remains constant during this time,
if you are moving parallel to a wall, for
instance.
Malfunctions
The indicator lamp within the button
flashes and a status message appears in
the Check Control.
Please take note of the supplementary
information provided in the Control Display.
Switch the system off and have the cause
of the malfunction corrected by your BMW
center.
