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 vehi-
cle. Four ultrasonic sensors in both the 
bumpers monitor the distance to the near-
est object. The sensors at the front and at 
the two rear corners have a range of 
approx. 1.64 ft/50 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 
In ignition key position 2, the system auto-
matically assumes operational status after 
a few seconds each time you engage 
reverse gear or selector-lever position R. 
Wait this short period before revers-
ing.

Manual activation
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. 
Signal tones
The signal indicating the distance to the 
nearest obstacle is directional. Thus, an 
object detected to the left rear of the vehi-
cle 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 continu-
ous 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 message appears on the 
Control Display. Please note any supple-
mentary information that appears there. 
Switch the system off and have the cause 
of the malfunction corrected by your BMW 
center. 
PDC with visual warning* 
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display for the specific key in use. The 
Control Display will also indicate the pres-
