PDC Park Distance Con‐
trol
The concept
PDC supports you when parking. Slowly ap‐
proaching an object behind or, with the appro‐
priate equipment, also in front of your vehicle is
signaled by:

Online Edition for Part no. 01 40 2 963 334 - VI/15
▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on obsta‐
cles and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷By the front middle sensors and the two
corner sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.▷When a collision is imminent
Information
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal tone.
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively interfere in the respective situations. ◀
WARNING
Due to high speeds when PDC is acti‐
vated, the warning can be delayed due to phys‐
ical circumstances. There is risk of injuries or
risk of property damage. Avoid approaching an
object too fast. Avoid driving off fast while PDC
is not yet active. ◀

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 ve‐
hicle, 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.
If objects are located both in front of and to the
rear of the vehicle, an alternating continuous
signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with Steptronic transmission.
Volume
The ratio of the PDC signal tone volume to the
entertainment volume can be adjusted.1. "Multimedia", "Radio" or
"Settings"2."Tone"3."Volume settings"4."PDC"5.To adjust: turn the controller.6.To store: press the controller.
Settings are stored for the profile currently

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 Con‐
trol 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 col‐
ors: red, green and yellow.

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.▷For objects with porous surfaces.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered with
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed bumps.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.Malfunction

Detection of objects
Very low obstacles or high, protruding objects
such as ledges may not be recognized by the
system.
Assistance functions also take into account data
of the PDC.
Follow instructions in the PDC chapter, refer to
page 126.
The objects displayed on the Control Display
under certain circumstances are closer than
they appear. Therefore, do not estimate the
distance from the objects on the display.
Parking assistant
The concept
This system assists the driver in parking parallel
to the road.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best possi‐
ble parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC, the
parking assistant and, where applicable, the
rearview camera, and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 126.
