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 transmission position P is engaged.
Volume
You can set the volume of the PDC signal tone,
refer to page
The setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
