High-beam AssistantThe concept
The high-beam Assistant detects other traffic
participants early on and automatically
switches the high beams on or off depending
on the traffic situation. The assistant ensures
that the high beams are activated whenever
the traffic situation allows. In the low speed
range, the high beams are not switched on by
the system.
General information
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The driver can intervene at any time and switch
the high beams on and off as usual.
Depending on the version of the system in the
vehicle, the high beams may not switch off for
oncoming vehicles, but may only be dimmed in
the areas that blind oncoming traffic. In this
case, the blue indicator light will stay on.
Activating1.Turn the light switch to position .2.Press and hold PC button on blinker lever.
The indicator lamp in the instrument
cluster lights up.
When the low beams are on, the lights are au‐
tomatically brightened or dimmed.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams.
Deactivating The High-beam Assistant can be switched off
when manually switching the high beams on
and off, refer to page 103. To reactivate the
High-beam Assistant, press the button on the
turn signal lever.
System limits The High-beam Assistant cannot serve as a
substitute for the driver's personal judgment of
when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where required to avoid a safety risk.
The system is not fully functional in the follow‐
ing situations, and driver intervention may be
necessary:▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; or at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on highways.▷In poorly-lit towns and cities or in the pres‐
ence of highly reflective signs.▷When the windshield behind the interior
mirror is fogged over, dirty or covered with
stickers, etc.
Fog lights
Front fog lights
General information
The low beams must be switched on before
switching on the front fog lamps.

▷The indicator lamp does not light up when,
e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags
on the front passenger side are activated.
Detected child seats
The system generally detects children seated
in a child seat, particularly in child seats re‐
quired by NHTSA when the vehicle was manu‐ factured. After installing a child seat, make
sure that the indicator lamp for the front-seat
passenger airbags lights up. This indicates
that the child seat has been detected and the
front-seat passenger airbags are not activated.
Strength of the driver's and front-seat
passenger airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passeng‐ er's seat.
With a respective message appearing on Con‐
trol Display calibrate the front seats to keep the accuracy of this function over the long-
term.
Calibrating the front seats WARNING
There is risk of jamming when moving
the seats. There is risk of injuries or risk of
property damage. Make sure that the area of
movement of the seat is clear prior to any ad‐
justment.◀
A corresponding message appears on the
Control Display.
1.Press the switch and move the respective
seat all the way forward.2.Press the switch forward again. The seat
still moves forward slightly.3.Readjust the seat to the desired position.The calibration procedure is completed when
the message on the Control Display disap‐
pears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Intelligent Safety The conceptIntelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent a imminent collision.▷Front-end collision warning with braking
function, refer to page 140.▷Pedestrian warning with City Braking func‐
tion, refer to page 144.▷Night Vision with pedestrian and animal
detection, refer to page 147.▷Lane departure warning, refer to
page 150.▷Active Blind Spot Detection, refer to
page 153.▷Side collision warning, refer to page 156.
Information
WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to sys‐
tem limits, warnings or reactions of the system
may not be output or they may be output too
late or incorrectly. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic closely and actively inter‐
fere in the respective situations.◀

▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, e.g., DSC OFF.▷If the area of the front windshield in front of
the interior mirror is dirty or covered.▷Depending on equipment, if the radar sen‐
sor is dirty or obscured.▷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 there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
e.g. the warning time, the more warnings are
displayed. However, there may also be an ex‐
cess of premature warnings.
Pedestrian warning with City
braking function
The concept The system can help prevent accidents with
pedestrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
The camera in the area of the rearview mirror
controls the system.
Active Protection: if a collision seems to be un‐
avoidable, PreCrash functions are triggered.
General information The system warns of possible collisions with
pedestrians at speeds from ap‐
prox. 6 mph/10 km/h to ap‐
prox. 35 mph/60 km/h and supports you with a
braking intervention shortly before a collision.
Under those circumstances it reacts to people
who are within the detection range of the sys‐
tem.
Detection range
The detection area in front of the vehicle is div‐
ided into two areas
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are lo‐
cated within the central area. A warning is is‐
sued about pedestrians who are located within
the extended area only if they are moving in
the direction of the central area.

Warning with braking function
Display
If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a sig‐
nal sounds.
Intervene immediately by braking or make an
evasive maneuver.
Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise for the brake booster is sufficiently
quick and hard stepping on the brake pedal.
The system can additionally assist with braking
intervention if there is risk of a collision.
At low speeds the vehicle can be decelerated
to a complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Detection range
The detection potential of the camera is lim‐
ited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians having a body size less than
32 in/80 cm.
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.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷If the field of view of the camera or the front
windshield are dirty or covered.▷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.Seite 146ControlsSafety146

▷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.
Night Vision with pedestrian
and animal detection
The concept
Night Vision with pedestrian and animal detec‐
tion is a night vision system.
An infrared camera scans the area in front of
the vehicle and issues a warning if it detects
pedestrians and animals on the street. Warm
objects that are similar in shape to human be‐
ings or animals are detected by the system. If
necessary, the heat image can be displayed on
the Control Display.
Heat image
The image shows the heat radiated by objects
in the field of view of the camera.
Warm objects have a light appearance and
cold objects a dark appearance.
The ability to detect an object depends on the
temperature difference between the object
and the background and on the level of heat
radiation emitted by the object. Objects that
are similar in temperature to the environment
or that radiate very little heat are difficult to de‐
tect.
For safety reasons, when driving at speeds
above approx. 3 mph/5 km/h and in low ambi‐
ent light, the image is only displayed when the
low beams are activated.
A still image is displayed at regular intervals for
a fraction of a second.
Pedestrian and animal detection
Object detection and warning only functions in
darkness.
Objects whose form is similar to people with
sufficient heat radiation are detected.
In addition, the system also detects animals
above a certain minimum size, e.g., deer.
Display on the Control Display with heat image
activated:
▷People detected by the system: in light
yellow.▷Animals detected by the system: in dark
yellow.
Range of object detection, with good ambient
conditions:
▷Pedestrian detection: up to approx.
330 ft/100 m▷Detection of large animals: up to approx.
490 ft/150 m▷Detection of medium animals: up to ap‐
prox. 230 ft/70 m
Environmental influences can limit the availa‐
bility of object detection.
If the vehicle systems detect that the vehicle is
located in a residential area, the animal detec‐
tion is temporarily switched off.

Display
Warning of people or animals in
danger
If a collision with a person or an animal de‐
tected in this way is imminent, a warning sym‐
bol appears on the instrument cluster 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 for the pedestrian warning
consists of two parts:
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
With animal warnings, no distinction is made
between the central or expanded area.
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
increases, the area becomes longer and wider,
e.g.

ver.
The displayed symbol shows the side of the
road on which the person or animal was de‐
tected.
Prewarning
Prewarning for persons is displayed when a
person is detected in the central area immedi‐
ately in front of the vehicle as well as on the left
or right side in the extended area.
Prewarning for animals is displayed when an
animal is detected in the front of the vehicle.
The driver must intervene actively when there
is a prewarning.
Acute warning
Acute warning is displayed if a person or an
animal is detected in direct proximity if front of
the vehicle.
The driver must immediately intervene actively
when there is an acute warning.
Active Protection: if a collision seems to be un‐
avoidable, PreCrash functions are triggered.

Display in the Head-up Display
The warning is displayed simultaneously in the
Head-up Display and on the instrument clus‐
ter.
System limits
Basic limits System operation is limited in situations such
as the following:▷On steep hills, in steep depressions or in
tight curves.▷When the camera is dirty or the protective
glass is damaged.▷In heavy fog, rain or snowfall.▷At very high external temperatures.
Limits of pedestrian and animal
detection
In some situations, it may occur that pedes‐
trians are detected as animals or animals as
pedestrians.
Small animals are not detected by the object
detection function, even if they are clearly visi‐
ble in the image.
Limited detection, e.g. in the following circum‐
stances:
▷People or animals who are fully or partially
covered, especially when their heads are
covered.▷People who are not in an upright position,
e.g., lying down.▷Cyclists on unconventional bicycles (e.g.,
recumbent bicycles).▷After physical damage to the system, e.g.,
after an accident.
No display on the rear screen
The image from Night Vision cannot be dis‐
played on the rear screen.
Lane departure warning
The concept This system alerts at speeds be‐
tween 45 mph/70 km/h and 130 mph/210 km/h
when the vehicle on roads with lane markings
is about to leave the lane.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Vehicles with side collision warning: if the vi‐
brating steering wheel is ignored and the lane
marking crossed, the system intervenes with a
brief active steering intervention and helps to
maintain the vehicle in the lane.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess
route and traffic situation. There is risk of an
accident. Adjust the driving style to the traffic
conditions. Watch traffic closely and actively
interfere in the respective situations. In the
event of a warning, do not unnecessarily jerk
the steering wheel.◀
