Display
Signal tones When approaching an object, an intermittent
sound indicates the position of the object. E. g.
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, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
An interval tone is interrupted with the appro‐
priate equipment after about 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 selector
lever position P is engaged on vehicles with
Steptronic transmission.
Volume
The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume set‐
tings of the radio.
Settings are stored for the profile currently 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 already displayed on the
Control Display before a signal sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in the
colors green, yellow and red.
When the image of the rearview camera is dis‐
played, the reel can be made to PDC:
