Park Distance Control (PDC)
*
The PDC assists you when you are 
parking. Acoustic signals warn you 
of the distance to an obstacle. In addi-
tion, four ultrasonic sensors in each the 
front and rear bumpers measure the 
distance from the nearest object. The 
monitoring range for the four front sen-
sors and that of the two rear corner 
sensors ends approx. 2 feet (60 cm) 
beyond the respective bumper. The two 
center sensors cover a distance of 
approx. 5 feet (1.50 m).

The system starts to operate automati-
cally about one second after you move 
the selector lever to "R" when the igni-
tion key is in position 2. It is similarly 
deactivated when you move the selec-
tor lever position from the "R" position. 
The indicator lamp in the button (arrow) 
comes on to signal the active status.
Manual activation/deactivation is possi-
ble using the button in the center 
console (arrow) (indicator lamp comes 
on/goes out). The system deactivates 
once the vehicle travels approximately 
160 ft (50 m) or exceeds a speed of 
about 18 mph (30 km/h). It must then be 
switched on again as desired.
Acoustical signals
The distance to an obstruction in the 
front is indicated by a higher interval 
tone, while the distance to an obstruc-
tion in the rear is indicated by a deeper 
tone. As the distance between vehicle 
and object decreases, the intervals be-
tween the tones become shorter. A 
continuous tone indicates the presence 
of an object less than 1 ft. (30 cm) 
away.
The warning signal is canceled after ap-
prox. three seconds if the distance to 
the obstruction remains constant during 
this time (if you are moving parallel to a 
wall, for instance).
System malfunctions are indicated by a 
short, continuous tone and a flashing 
indicator lamp (indicator lamp only 
when the system is activated by shifting 
the transmission into "R").
Switch the system off and consult an 
authorized BMW center to have the 
problem corrected.
