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

Radar sensor
A radar sensor is located in the front bumper
for detecting vehicles on the road ahead of the
vehicle.
A dirty or covered sensor may hinder the de‐
tection of vehicles.
▷If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.▷Do not cover the view field of the radar
sensor.Camera
The camera is located near the base of the
mirror.
Keep the windshield in the area behind the in‐
terior rearview mirror clean and clear.
A dirty or covered area in front of the interior
mirror may hinder the detection of vehicles.
▷If necessary, clean the area in front of the
interior mirror, e.g., carefully remove salt
residue in the winter.

System limits
When driving within narrow driving lanes, e.g.,
in construction zones or rescue lanes, the sys‐
tem cannot be activated or meaningfully used.
Limited detection capacity
Because of the limits to the detection ca‐
pacity of the camera and the sensor, you
should be alert at all times so that you can in‐
tervene actively, if necessary; otherwise, there
is the danger of an accident occurring.◀
Complying with country-specific laws
When the Congestion Assistant is used,
observe specific national laws.◀
Cruise control
The concept The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
General information
Depending on the set driving program, the
characteristics of the cruise control can
change in certain areas.

Obstacle marking
General information
Obstacles behind the vehicle are detected by
the PDC sensors and, when appropriately
equipped, detected by the rearview camera.
Marks for detected obstacles can be shown in
the rearview camera image.
Their colored steps match the markings of the
PDC. This simplifies estimation of the distance
to the object shown.
Parking using pathway and turning
circle lines
1.Position the vehicle so that the turning cir‐
cle lines lead to within the limits of the
parking space.2.Turn the steering wheel to the point where
the pathway line covers the corresponding
turning circle line.

Ultrasound sensors measure parking spaces
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
and braking and if necessary changes the drive
modes. Hold down the parking assistant but‐
ton for the duration of the parking operation. At
the end of the parking procedure, the P selec‐
tor lever position is engaged.
When parking, also take note of the visual and
acoustic information and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 150.
Hints Personal responsibility
Even an active system does not relieve
the driver from personal responsibility for the
driving process.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Continuously and attentively monitor the driv‐
ing process, the area surrounding the vehicle
and the traffic situation, and actively intervene
when required, otherwise, there is a risk of an
accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
For measuring parking spaces▷Maximum speed while driving forward ap‐
prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.
Suitable parking space
▷Gap between two objects with a minimum
length of approx. 5 ft/1.5 m.▷Minimum length of the gap: own vehicle's
length plus approx. 4 ft/1.2 m.▷Minimum depth: approx. 5 ft/1.5 m.
