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 the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷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:

System limits
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, dam‐
aged or out of position.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.▷With tow bars and trailer couplings of other
vehicles.▷With thin or wedge-shaped objects.▷With moving objects.▷With elevated, protruding objects such as
ledges or cargo.▷With objects with corners and sharp edges.▷With objects with a fine surface structure
such as fences.Seite 154ControlsDriving comfort154

▷Possible on snow-covered or slippery road
surfaces.▷When there are obstacles that are hard to
overcome, such as curbs.▷When there are obstacles that suddenly
arise.▷If the Park Distance Control PDC displays
clearances that are too small.▷If a maximum number of parking attempts
or the time taken for parking is exceeded.▷If a turn signal has been actuated contrary
to the desired side for parking.▷When switching to another function on the
Control Display.
A Check Control message is displayed.
Resume An interrupted parking procedure can be con‐
tinued if needed.
Follow the instructions on the Control Display
to do this.

The parking assistant does not offer assis‐
tance in the following situations:

Functional limitations
The system may not be fully functional in the
following situations:
▷On bumpy road surfaces such as gravel
roads.▷On slippery ground.▷On steep uphill or downhill grades.▷With accumulations of leaves/snow in the

move into the blind area of the sensors before
or after a continuous tone sounds.
The parking assistant may identify parking
spaces that are not suitable for parking.
Malfunction
A Check Control message is displayed.
The parking assistant failed. Have the system
checked.
