pressing on the brake pedal or accelerator
pedal.
Symbol flashes red and a signal sounds:
You are requested to intervene by brak‐
ing or make an evasive maneuver.
The system has been interrupted or dis‐
tance control is temporarily suppressed
because the accelerator pedal is being
pressed; a vehicle was not detected.

System limits
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Deceleration
The system does not decelerate in the following
situations:▷For pedestrians, cyclists or similarly slow-
moving road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.▷Unlit vehicles or vehicles with nonworking
lighting at night.
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, for ex‐
ample, when rapidly approaching a truck.
When a vehicle driving ahead of you is reliably
detected, the system requests that the driver
intervene by braking and carrying out evasive
maneuvers, if needed.

InformationWARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations. ◀
WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible. ◀

PDC Park Distance Con‐trol
The concept
PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is avail‐
able - then the object is reported through:▷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 inches/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 intervene 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 a risk of injury or
risk of property damage. Avoid approaching an
object too fast. Avoid driving off fast while PDC
is not yet active. ◀

Functional requirements To ensure full functionality:
▷Do not cover sensors, for example, with
stickers, bicycle racks.▷Keep the sensors clean and free of ice.
To clean: when using high-pressure washers,
do not spray the sensors for long periods and
maintain a distance of at least 12 inches/30 cm.

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 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 inches/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.
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.

played, the switch can be made to PDC:

Information WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
information regarding the system limits and ac‐
tively intervene, if needed. ◀
Limits of ultrasonic measurement Ultrasonic measuring might not function under
the following circumstances:▷For small children and animals.▷For persons with certain clothing, for exam‐
ple coats.▷With external interference of the ultra‐
sound, for example from passing vehicles
or loud machines.▷When sensors are dirty, iced over, damaged
or out of position.▷If cargo protrudes.▷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.▷For objects with porous surfaces.
Low objects already displayed, for example,
curbs, can move into the blind area of the sen‐
sors 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, for example, in underground
garages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, for exam‐
ple, 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.
With front PDC: to reduce false alarms, switch
off automatic PDC activation on obstacle detec‐
tion, for example in car washes, refer to
page 135.
Malfunction A Check Control message, refer to page 81, is
displayed in the instrument cluster.
