PDC Park Distance Control *
The concept
The PDC assists you when you are parking.
Acoustic signals inform you of the distance
to an obstacle. Four ultrasonic sensors in
both the front and rear bumpers monitor
the distance to the nearest object. The
monitoring range of the front and two rear
corner sensors extends outward roughly
2 ft (60 cm), while the rear bumper's two
centrally located sensors detect objects at
distances of up to approximately 4.9 ft
(1.50 m).
Automatic function
Whenever the ignition is on the system
automatically assumes operational status
each time the selector lever is pressed
briefly in R.
Manual activation
Press the button, the indicator lamp lights
up.
The system is automatically deactivated
once the vehicle travels approximately
165 ft (50 m) or exceeds a speed of roughly
18 mph (roughly 30 km/h); the indicator
lamp goes out. You can reactivate the
system manually as needed.
Manual deactivation
Press the button again; the indicator lamp
goes out.
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
approximately 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 panel.
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.
