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.
When the distance to a detected object is less
than approx. 8 in/20 cm, a continuous tone is
sounded.
When there are objects in front of and behind the
vehicle at the same time, with a distance smaller
than approx. 8 in/20 cm, an alternating constant
tone will sound.
Steptronic transmission: the intermittent tone
and constant tone are switched off if the selector
lever position P is engaged.
The intermittent tone is switched off after a short
time when the vehicle is stationary.
Volume
The PDC signal tone volume can be adjusted.
1.
"CAR"
2. "Settings"
3. "Driver Assistance"
4. "Parking and Maneuvering"
5. "Volume PDC signal"
6. Set the desired value.
Visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are already displayed on the Control
Display before a signal sounds.
The display appears as soon as PDC is activated.
The range of the sensors is represented in the
colors green, yellow and red when obstacles are
detected.
Lanes are faded in for better estimation of the re‐
quired space.
When the image of the rearview camera is dis‐
played, the switch can be made to PDC or to a
different view with obstacle markings as needed:
1. Press the Controller to the left, if needed.
2. For instance "Park. sensors only"
Cross traffic warning: depending on the equip‐
ment, it is warned in the PDC display against ve‐
hicles approaching in the front or rear from the
side.
