Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀

Avoid driving quickly with PDC
Avoid approaching an object quickly.

Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀

Limits of ultrasonic measurement

The detection of objects can reach the physical
limits of ultrasonic measurement, e.g.:

With tow bars and trailer hitches.

With thin or wedge-shaped objects.

With low objects.

With objects with corners and sharp edges.

Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.

False warnings

PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:

In heavy rain.

When sensors are very dirty or covered in
ice.

When sensors are covered in snow.

On rough road surfaces.

In large buildings with right angles and
smooth walls, e.g., in underground garages.

In heavy exhaust.

Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.

Switching on automatically

Select transmission position R with the engine
running.

Switching off automatically

The system switches off and the LED goes out:

After approx. 160 ft/50 m when driving for‐
ward.

Above approx. 22 mph/36 km/h when driv‐
ing forward.

Switch on the system again if necessary.

Switching on/off manually

Press the button.

On: the LED lights up.

Off: the LED goes out.

Signal tones

When approaching an object, an intermittent
tone is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
