High-beam Assistant The concept
When the low beams are activated, this system automatically switches the high beams on and
off. The procedure is controlled by a camera on
the front of the interior rearview mirror. The as‐
sistant ensures that the high beams are acti‐
vated whenever the traffic situation allows. The
driver can intervene at any time and switch the
high beams on and off as usual. In the low
speed range, the high beams are not switched
on by the system.

Front-end collision
warning with City Brak‐
ing function
The concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is done
with limited force and duration.
The system is controlled via a camera in the
base of the mirror.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system reac‐
tions.
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.Detection range
It responds to objects if they are detected by
the system.
Information WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to system
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 conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀

Pedestrian warning with
city braking function
The concept
The system can help prevent accidents with pe‐
destrians.
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.
A camera at the base of the rearview mirror
controls the system.
General information
With sufficient brightness, the system warns
about possible collision danger with pedes‐
trians starting at approx. 6 mph/10 km/h to ap‐
prox. 35 mph/60 km/h and assists with braking
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.
Information WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to system
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 conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀

tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system decelerates
you may compensate it by briefly accelerating.
After releasing the gas pedal the system is reac‐
tivated and controls speed independently.
Weather
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 recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected.
Drive attentively, and react to the current traffic
situation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Malfunction
A Check Control message is displayed if the sys‐
tem fails or was automatically deactivated.
The system may not be fully functional in the
following situations:▷When an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
front windshield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.
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 is insufficient.
Information WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:
▷On winding roads.▷In heavy traffic.Seite 106CONTROLSDriving comfort106

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 ve‐
hicle, 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 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and to the
rear of the vehicle, an alternating continuous
signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
