The alarm system is switched on.▷Indicator lamp flashes for approx. 10 sec‐
onds, then it flashes briefly every 2 sec‐
onds:
Interior motion sensor and tilt alarm sensor
are not active, as doors, hood, or tailgate
are not correctly closed. Correctly closed
access points are secured.
When the still open access points are
closed, interior motion sensor and tilt alarm
sensor will be switched on.▷The indicator lamp goes out after unlock‐
ing:
The vehicle has not been tampered with.▷The indicator lamp flashes after unlocking
until the engine ignition is switched on, but
no longer than approx. 5 minutes:
An alarm has been triggered.
Tilt alarm sensor The tilt of the vehicle is monitored.
The alarm system responds in situations such
as attempts to steal a wheel or when the car is
towed.
Interior motion sensor The windows and glass sunroof must be
closed for the system to function properly.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sen‐
sor can be switched off together, such as in
the following situations:▷In automatic car washes.▷In duplex garages.▷During transport on trains carrying vehi‐
cles, at sea or on a trailer.▷With animals in the vehicle.
Switching off the tilt alarm sensor and
interior motion sensor
Press the remote control button again
within 10 seconds as soon as the vehicle
is locked.
The indicator lamp lights up for approx. 2 sec‐
onds and then continues to flash.
The tilt alarm sensor and interior motion sen‐
sor are turned off until the vehicle is locked
again.
Switching off the alarm
▷Unlock vehicle with the remote control or
switch on the ignition, if needed through
emergency detection of remote control, re‐
fer to page 35.▷With Comfort Access: if you are carrying
the remote control on your person, grasp
the driver side or front passenger side door
handle completely.

Information WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively 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 ex‐
ample coats.▷With external interference of the ultra‐
sound, for example 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.▷For objects with porous surfaces.▷If cargo protrudes.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.
If necessary, switch off automatic PDC activa‐
tion on obstacle detection, for example in car
washes, to reduce false alarms.
Malfunction
A Check Control message is displayed.
The range of the sensors is shown as a shaded
area on the Control Display.
PDC has failed. Have the system checked.
Surround View
The concept Surround View comprises various camera as‐
sistance systems that help the driver when
parking, maneuvering, and at complex exits
and intersections.

Display on the Control Display
Functional requirement▷The rearview camera is switched on.▷The tailgate is fully closed.▷Keep the recording range of the camera
clear. Protruding cargo or carrier systems
and trailers that are not connected to a
trailer power socket can lead to malfunc‐
tions.
Activating assistance functions
More than one assistance function can be ac‐
tive at the same time.
▷Parking aid lines
"Parking aid lines"
Lanes and turning radius are indicated.
▷Obstacle marking
"Obstacle marking"
Spatially-shaped markings are displayed.
Pathway lines
Pathway lines can be superimposed on the im‐
age of the rearview camera.
Pathway lines help you to estimate the space
required when parking and maneuvering on
level roads.
Pathway lines depend on the current steering
angle and are continuously adjusted to the
steering wheel movements.
Turning circle lines
Turning circle lines can only be superimposed
on the rearview camera image together with
pathway lines.
Turning circle lines show the course of the
smallest possible turning radius on a level
road.
Only one turning radius line is displayed after
the steering wheel is turned past a certain an‐
gle.
Obstacle marking
Obstacles behind the vehicle are detected by
the PDC sensors and, when respectively
equipped, detected by the rearview camera.
Obstacle markings can be faded into the image
of the rearview camera.
Their colored margins of the obstacle mark‐
ings match the markings of the PDC.
