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.◀

marking on both sides is detected.▷Below approx. 43 mph, 70 km/h: lane
marking on both sides or a vehicle driving
ahead is detected.▷At least one hand on the steering wheel
rim.▷Wide curves.▷Drive in the center of the lane.▷Turn signal not actuated.▷Camera calibration immediately after vehi‐
cle delivery is completed.
Switching on/off
Switching on Press button on the steering wheel.
Steering wheel symbol lights up gray.
System activates automatically as soon as all
function conditions are fulfilled, refer to
page 179.

ing and side collision warning are active. Set‐
tings on the Control Display remain un‐
changed.
Switch off Press button on the steering wheel.
The indicator goes out.
The system does not manipulate steering.
Automatic interruptionThe system is automatically interrupted in the
following situations:▷At a speed above 130 mph/210 km/h.▷When the steering wheel is released.▷When you manipulate steering.▷When you leave your own lane.▷When the turn signal is on.▷When the lane is too narrow.▷If for a particular time no lane marking is
detected and there is no vehicle driving in
front.
Steering wheel symbol lights up gray.
The system is paused and does not
manipulate steering.
If the system conditions are met, the system
reactivates automatically.

Overview
Camera
The camera is installed near the interior rear‐
view mirror.
Keep the windshield in the area behind the in‐
terior rearview mirror clean and clear.
General information
The system is active up to a speed
of 75 mph/120 km/h.
System limits
Functional limitations The system may not be fully functional or may
not be available in the following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷At rapid steering angles.▷When driving very close to the vehicle in
front of you.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the field of view of the camera or the front
windshield are dirty or covered.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.▷When it is dark outside.Malfunction
A Check Control message is displayed when
there is a camera malfunction. Visit the nearest
dealer’s service center or another qualified
service center or repair shop.
Active roll stabilization
The concept The system reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
The lateral inclination of the vehicle is bal‐
anced out by permanent adjustment on the
front and rear axles. The vehicle is thus always
stabilized.
Agility and driving comfort are increased under
all driving conditions.
General information
The system offers several different damping
settings.
These are assigned to the different driving
modes of the Driving Dynamics Control, refer
to page 110.
