Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
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.
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.

InformationWARNING
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.◀

WARNING
The system does not relieve 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. Adjustthe driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀

The system is automatically interrupted in the
following situations:
▷When the brakes are applied.▷If selector lever position D is disengaged.▷If DTC Dynamic Traction Control is acti‐

an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐

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.
Parking using pathway and turning

dius lines lead to within the limits of the
parking space.Seite 158ControlsDriving comfort158

Detection of objects
Very low obstacles as well as high, protruding
objects such as ledges may not be detected by
the system.
Assistance functions also take into account
data of the PDC.
Follow instructions in the PDC chapter, refer to
page 154.
The objects displayed on the Control Display
under certain circumstances are closer than
they appear. Do not estimate the distance from
the objects on the display.
Top View
The concept Top View provides assistance in parking and
maneuvering. The area around the vehicle is
shown on the Control Display.
General information The image is captured by two cameras
integrated in the exterior mirrors, by the rear‐
view camera and a camera on the front of the
vehicle.
The range is no more than approx. 6.5 ft/2 m to
the side, front and rear.
Obstacles within this range are thus displayed
early on the Control Display.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. There is risk of an accident.
Adjust the driving style to the traffic condi‐ tions. Watch traffic and vehicle surroundings
closely and actively interfere in the respective
situations.◀

Displaying the turning radius and
pathway lines
▷The static, red turning radius line shows
the space needed to the side of the vehicle
when the steering wheel is turned all the
way.▷The variable, green pathway line assists
you in assessing the amount of space ac‐
tually needed to the side of the vehicle.
The lane line depends on the engaged
gear and the current steering angle. The
track line is continuously adjusted for the
steering wheel movement.
"Parking aid lines"
Turning circle and pathway lines are displayed.
System limits
A Check Control message is displayed when a
camera is not working.
Side View The concept
Side View provides an early look at cross traffic
at blind driveways and intersections. Road
users concealed by obstacles to the left and
right of the vehicle can only be detected rela‐
tively late from the driver's seat. To improve
the viewing, each camera, front and rear on the
vehicle, detects the traffic area on the side.
Which camera is active is shown on the top
edge of the screen.
Information The images of the cameras are displayed, de‐
pending on the gear selected, on the Control
Display.
