If there are objects in front of and behind the ve‐
hicle at the same time, and they are at a distance
of less than approximately 20 cm, 8 in, an alter‐
nating continuous tone sounds.
Steptronic transmission: the intermittent tone
and the continuous tone are switched off when
selector lever position P is engaged.
The intermittent sound switches off a short while
after the vehicle comes to a standstill.
Volume control
The PDC acoustic signal volume can be adjus‐
ted.
1.
"CAR"
2. "Settings"
3. "Driver assistance"
4. "Parking and manoeuvring"
5. "Volume PDC signal"
6. Set the desired value.
The setting is saved for the current driver profile.
Visual warning
The vehicle's approach to an object is shown on
the Control Display. Objects that are further away
are already displayed before an acoustic signal is
given.
The display appears as soon as PDC is activated.
The recording range of the sensors is shown in
green, yellow and red if obstacles are detected
within the range.
Driving path lines are displayed for better estima‐
tion of the space required.
If the rear-view camera image is shown, it is pos‐
sible to change over to PDC or, if required, to an‐
other view with obstacle markings:
1. If necessary, push the Controller to the left.
2. For example "Parking sensors"
Crossing traffic warning: depending on the
equipment, the PDC display also warns of vehi‐
cles approaching from the sides at the front and
rear.
