▷When a vehicle is approaching at a speed
much faster than your own.▷In heavy fog, rain or snowfall.▷In tight curves or on narrow lanes.
Radar sensors
The radar sensors are located under the rear
bumper.
The system may not be fully functional in the
following situations:
▷Dirty or icy bumper.▷Stickers on the bumper.
A Check Control message is displayed when the
system is not fully functional.
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is governed
by the following:
FCC ID:
▷NBG009014A.
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 interfer‐
ence, and▷this device must accept any interference re‐
ceived, including interference that may
cause undesired operation.Any unauthorized modifications or changes to

Brake force display
The concept▷During normal brake application, the outer
brake lamps light up.▷During heavy brake application, the inner
brake lamps light up in addition.
Active Protection
The concept
The system is used to detect critical driving sit‐
uations that might lead to an accident. In in these
situations, preventative protection measures
are automatically undertaken to minimize the
risk in the event of an accident as much as pos‐
sible.
Critical driving situations may include:
▷Full application of the brakes.▷Severe understeering.▷Severe oversteering.
If the vehicle includes the collision warning fea‐
ture, impending collisions with vehicles driving
ahead or stopped in front of you can also be de‐
tected within the system's range.

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
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 con‐
ditions make it impossible to drive at a constant
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 vehicle
and cause an accident.◀

Cameras
The lenses of the Top View cameras are located
at the bottom of the exterior mirror housings.

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 relatively late
from the driver's seat. To improve visibility, two
cameras in the front of the vehicle record the
traffic situation on each side.
Capturing the image
Two cameras integrated in the bumpers capture
the image.
The cameras capture a maximum range of
330 ft/100 m.
Display
The images from both cameras are shown si‐
multaneously on the Control Display.
Check the traffic situation as well
Check the traffic situation around the ve‐
hicle on blind driveways and intersections with
your own eyes. Otherwise, an accident could re‐
sult from road users or objects located outside
the picture area of the Side View cameras.◀

Parking assistant
The concept
This system assists the driver in parking parallel
to the road.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.

closely and intervene if necessary; otherwise,
there is the danger of an accident.◀

cle can drown out the signal tones of the parking
assistant and PDC.

dicated on the Control Display.2.Follow the instructions on the Control Dis‐
play.

cated on the Control Display.3.Adjust the parking position yourself if nec‐
essary.
Notes
▷The parking assistant takes control of steer‐
ing for as long as the symbol for active park‐
ing appears on the display.▷The system maneuvers the vehicle to posi‐
tion it properly in smaller parking spaces, for
example.▷To achieve the best possible parking posi‐
tion, wait for the automatic steering wheel
movement after the gear change when the
vehicle is stationary.▷When parking in parking spaces on the driv‐
er's side, the corresponding turn signal must
be set.
Interrupting manually
The parking assistant can be interrupted at any
time by:
▷Grasping the steering wheel and steering
yourself.Seite 123Driving comfortControls123

Warm objects that are similar in shape to human
beings are detected by the system.
People detected by the system are displayed
with a slight yellow hue.
Under good ambient conditions, the pedestrian
detection system operates within a range of ap‐
prox. 50 ft/15 m to approx. 330 ft/100 m.
Environmental influences can limit the availabil‐
ity of pedestrian detection.
If pedestrian detection is not available, a symbol
is displayed in the heat image.
This symbol disappears when the function be‐
comes available again.
Warning of people in danger
If the system detects a person in a defined area
in front of the vehicle and if there is the danger
of collision with this person, a warning symbol
appears on the Control Display and in the Head-
up Display.
Although both the shape and the heat radiation
are analyzed, false warnings cannot be ruled out.
Warning area in front of the vehicle
The warning area in front of the vehicle is divided
into two areas.
▷Central area 1 directly in front of the vehicle.▷Expanded area 2 to the right and left.
The entire area moves along with the vehicle in
the direction of the steering angle and changes
with the vehicle speed. As the vehicle speed in‐
creases, the area becomes longer and wider, for
example.
Prewarning The yellow symbol is displayed when a
person is detected in the central area,
arrow 1, immediately in front of the ve‐
hicle.
The yellow symbol is displayed when a
person detected in the extended area,
arrow 2, is moving from the right or left
to the central area.
Acute warning The red symbol is displayed and a signal
sounds. You are requested to intervene
immediately by braking or making an
evasive maneuver.
Display in the Head-up Display The warning is displayed simultane‐
ously in the Head-Up Display and on the
Control Display. The displayed symbol
can vary with the people detected. For people
