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 switched on, when‐
ever 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, for example, in towns
and cities.
The driver can intervene at any time and switch
the high beams on and off as usual.
Activating1.Depending on the equipment, turn the light
switch into position
or .
2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster is illuminated, when the low
beams are switched on.
The high beams are switched on and off auto‐
matically.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams.
Deactivating
The High-beam Assistant is deactivated when
manually switching the high beams on and off,
refer to page 73. 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; and 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 and in the
presence of highly reflective signs.▷When the windshield behind the interior
mirror is fogged over, dirty or covered with
stickers, etc.
Fog lights

The parking lights or low beams must be
switched on.
Press button. The green indicator
lamp lights up.
If the automatic headlamp control, refer to
page 101, is activated, the low beams will
come on automatically when you switch on the
front fog lights.

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.
With instrument display: The red sym‐
bol is displayed and a signal 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. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with
some braking intervention if there is a risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g. by
deactivating the DSC Dynamic Stability Con‐
trol.
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
Information WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.◀
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.Seite 122ControlsSafety122

When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
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.
Information WARNING
The system does not release the driver
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 ac‐
tively intervene in the respective situations. In
the event of a warning, do not unnecessarily
jerk the steering wheel.◀

The concept
Two radar sensors in the rear bumper monitor
the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
If there is a risk of collision: the lamp in the ex‐
terior mirror flashes and the steering wheel vi‐
brates.
Information WARNING
The system does not release from the
personal responsibility to correctly assess visi‐
bility and traffic situation. There is risk of an ac‐
cident. Adjust the driving style to the traffic
conditions. Watch traffic closely and actively

Display
Signal tones When approaching an object, an intermittent
sound indicates the position of the object. E.g.
if an object is detected to the left rear of the
vehicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 inches/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
An interval tone is interrupted with the appro‐
priate equipment after about 3 seconds:
▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
