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.
