distance, there are four ultrasonic sensors in
each bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 2 ft/60 cm from
the front sensors

or both rear corner sensors,

or approx. 5 ft/1.50 m from the rear center sen-
sors.

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.

Automatic mode

With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you engage reverse
gear or move the automatic transmission selec-
tor lever to position R. Wait this short period
before driving.

Switching on manually

Press the button, the LED lights up.

Switching off manually

Press the button again; the LED goes out.
The system is automatically deactivated once
the vehicle travels approx. 165 ft/50 m or
exceeds a speed of approx. 20 mph or 30 km/h;
the LED goes out. You can reactivate the sys-
tem as needed.

Signal tones

When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, the tone sounds at the rear if the system
detects an object behind the car. 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.
The warning signal is canceled after approx.
3 seconds, if you are moving parallel to a wall.

Malfunction

The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the

Control Display. Have the system checked.
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 spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.

Manual mode

The LED above the button flashes in addition.

PDC with optical warning

You can also have the system show distances
to objects on the Control Display. The contours
of distant objects are shown on the Control Dis-
play even before the acoustic signal sounds.
