Park Distance Control PDC*

been detected by only one of the corner

The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals warn you of
the presence of an object behind your vehi-
cle.Four ultrasonic sensors in the bumper mea-
sure the distance.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning.Have the system checked.
An acoustic warning does not sound until an
object is closer than approx. 2 ft/60 cm to the
corner sensors, or closer than approx. 5 ft/
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not direct the
jet toward the sensors for lengthy periods and
only spray from a distance of at least 4 in/10 cm.

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, oth-
erwise physical circumstances may lead to the
system warning being issued too late.<
System limitations
Even with PDC, final responsibility for
estimating the distance between the

vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC
signal. Therefore, always drive cautiously, oth-
erwise there is a risk of personal injury or prop-
erty damage.<
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above
approx. 20 mph/30 km/h, the system switches
off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
Driving stability control
systems
An interval tone is interrupted after approx.
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
