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.
The intermittent tone is interrupted after approx.
3 seconds:
▷ If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.
▷ If moving parallel to a wall.
The signal tone is switched off:
▷ When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.
▷ When selector lever position P is engaged.
Volume
You can set the volume of the PDC signal, refer
to page 141 .
The setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal sounds. The display appears
as soon as PDC is switched on.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC has failed.
A message appears on the Control Display.
Have the system checked.
To ensure full operability:
▷ Keep the sensors clean and free of ice.
▷ When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.
