Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Radar sensor
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:▷OAYARS3-A
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:
▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
The desired speed is also maintained downhill,
but may not be maintained on uphill grades if
engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO drive mode, the ve‐
hicle may drop below the set desired speed in
some situations, e.g. on uphill grades.
Information 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.◀

General information
The system determines the position of the
lane markings and the vehicle driving ahead
using five radar sensors and a camera.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
In order to be able to use the system, place
your hands around the steering wheel.
The system is deactivated if the steering wheel
is no longer being touched.

System limits
When driving with gloves or with protective
covers, contact with the steering wheel cannot
be detected by the sensors. In this case sys‐
tem cannot be used.
When driving within narrow lanes, the system
cannot be activated or meaningfully used.
Do not use the system, e.g.:
▷In construction zones.▷In rescue lanes.▷Within city limits.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐

PDC Park Distance Control The conceptPDC is a support when parking. Objects that
you are approaching slowly in front of or be‐
hind the vehicle are indicated with:
▷Signal tones.▷Visual display.
With parking assistant: obstacles on the side of
the vehicle that are detected by the sensors of
the parking assistant, can also be reported by
the PDC. Side protection, refer to page 183.
General information
Ultrasound sensors in the bumpers and possi‐
bly sideways on the vehicle measure the dis‐
tances from objects.
The maneuvering range, depending on the ob‐
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷By the front center sensors at ap‐
prox. 74 in/70 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.▷By the corner sensors at ap‐
prox. 24 in/60 cm.Seite 180ControlsDriver assistance systems180

Parking aid linesPathway lines
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.
Parking using pathway and turning radius
lines1.Position the vehicle so that the red turning
radius line leads to within the limits of the
parking space.2.Turn the steering wheel to the point where
the green pathway line covers the corre‐
sponding turning radius line.
Obstacle marking
Obstacles behind the vehicle are detected by
the PDC sensors.
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.
