WARNING
Signal tones
General information
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 vehi‐
cle, 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 inches/25 cm, a continuous tone is
sounded.
If there are objects in front of and behind the ve‐
hicle at the same time, with a distance smaller
than approx. 10 in/25 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 ratio of the PDC signal tone volume to the
entertainment volume can be adjusted.
Via iDrive:
1.
"My Vehicle"
2. "iDrive settings"
3. "Tone"
4. "Volume settings"
5. "PDC"
6. Set the desired value.
The setting is stored for the driver profile cur‐
rently used.
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.
Pathway lines are faded in for better estimation
of the required 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:
"Rear view camera"
Crossing traffic warning, refer to page 235: de‐
pending on the equipment, it is warned in the
PDC display against vehicles approaching in the
front or rear from the side.
