Park Distance Control PDC*
The concept
PDC provides extra safety and conven-
ience during parking maneuvers. 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 near-
est object.
The front and rear sensors on the corners
have a range of approx. 2 ft/60 cm. The
two rear middle sensors have a range of
approx. 5 ft/1.50 m and the two front mid-
dle sensors of approx. 2.6 ft/80 cm.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching objects too fast, other-
wise the system may give warning of phys-
ical obstacles too late.
<
If you are driving with a trailer, the rear sen-
sors are unable to make proper measure-
ments – so they do not switch on.
Automatic mode
As of ignition key position 2, the system
automatically assumes operational status
after a few seconds each time you engage
reverse gear or selector-lever position R.
Wait this short period before park-
ing.
<
You can have a signal tone pro-
grammed into the system to verify
that the PDC is active.

Automatic deactivation
After driving a distance of more than
approx. 160 ft/50 m or exceeding a speed
of approx. 20 mph/30 km/h, the system
switches off and the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Manual mode
Press the button; the indicator lamp comes
on.
Manual deactivation
Press the button again; the indicator lamp
goes out.
Signal tones
The distance to an object behind the vehi-
cle is signaled in accordance with the posi-
tion by an intermittent tone from a loud-
speaker in the rear-end.
The distance to an object in front of the
vehicle is signaled by an intermittent tone
from a loudspeaker beneath the instrument
cluster.
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 near-
est 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.
Malfunction
The indicator lamp flashes and a short
steady signal tone is sounded.
Switch the system off and have the cause
of the malfunction corrected by your BMW
Sports Activity Vehicle Center.
