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).380de619
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 signalsThe 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.
