otherwise, there is the danger of an accident
occurring.◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly in the curve, although
curves cannot be anticipated in advance.
Therefore, drive into a curve at an appropriate
speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not
be detected at all, or not until after a consider‐
able delay.
When approaching a curve, the system may
react briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away
In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines or
behind bumps in the road.
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, for
example.
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 shipment.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.Seite 144ControlsDriving comfort144

Congestion Assistant
The concept In congestion situations, the system controls
the speed, steers independently as required
and keeps the vehicle close to the center of
the lane.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you. The distance that the vehicle
maintains to the vehicle ahead of you can be
varied. For safety reasons, it depends on the
speed. To maintain a certain distance, the sys‐
tem automatically reduces the speed, applies
the brakes lightly, or accelerates again if the
vehicle ahead begins moving faster.
When lane markings are detected, the system
keeps the vehicle in the center of the lane. For
this purpose, the system steers independently
as needed, for example, during cornering.
General information The congestion assistant determines speed
and distance from the vehicle in front and the
position of the lane markings via a radar sensor
and a camera.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
The system is deactivated as soon as the
steering wheel is no longer being touched.
In order to be able to use the Congestion As‐
sistant, place your hands around the steering
wheel.
When driving with gloves or with protective
covers, contact with the steering wheel cannot
be detected by the sensors. The system in this
case cannot be used.
Hints Personal responsibility
Even an active system does not release
the driver from personal responsibility for the
driving process, especially for lane tracking,adaptation of speed, distance and driving style
to the traffic conditions.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Monitor the driving process, the surrounding
area and what is occurring in traffic continu‐
ously and attentively and actively intervene as
required, e.g., by braking, steering or making
an evasive maneuver.◀
Unfavorable weather conditions
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
recognition of vehicles and lane limits as well
as short-term interruptions for vehicles that are
already detected. Drive attentively, and react to
the current traffic events. Intervene actively
when necessary, e.g., by braking, steering or
making an evasive maneuver, otherwise, there
is danger of an accident.◀
Functional requirements▷Drive on approved road type. The data on
this are stored in the navigation system.
Approved road types are highways.▷Sufficient lane width.▷Lane marking on both sides is detected.▷Vehicle driving ahead is detected.▷Speed below 25 mph/40 km/h.▷Both hands on the steering wheel rim.▷Sufficient curvature.▷Drive in the center of the lane.Seite 145Driving comfortControls145

equipped, detected by the rearview camera.
Marks for detected obstacles can be shown in

on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and during the parking proce‐
dure takes control of steering, the acceleration
