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
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations. ◀

Warning sensitivityThe more sensitive the warning settings are,
the more warnings are displayed. However,
there may also be an excess of false warnings.
Person warning with City
light 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 interior mirror con‐
trols 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
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective 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, for
example by braking, steering or evading.
Engine power
The desired speed may not be maintained on
uphill grades if engine power is insufficient.
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
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
Using this system, a desired speed can be ad‐
justed using the buttons on the steering wheel.
The system maintains the desired speed. The
system accelerates and brakes automatically as
needed.
General information
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Depending on the driving settings, the features
of the cruise control can change in certain
areas.

The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
information regarding the system limits and ac‐
tively intervene, if needed. ◀
Limits of ultrasonic measurement Ultrasonic measuring might not function under
the following circumstances:▷For small children and animals.▷For persons with certain clothing, for exam‐
ple coats.▷With external interference of the ultra‐
sound, for example from passing vehicles
or loud machines.▷When sensors are dirty, iced over, damaged
or out of position.▷If cargo protrudes.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.▷With tow bars and trailer couplings of other
vehicles.▷With thin or wedge-shaped objects.▷With moving objects.▷With elevated, protruding objects such as
ledges or cargo.▷With objects with corners and sharp edges.▷With objects with a fine surface structure
such as fences.▷For objects with porous surfaces.
Low objects already displayed, for example,
curbs, can move into the blind area of the sen‐
sors before or after a continuous tone sounds.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:▷In heavy rain.▷When sensors are very dirty or covered with
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed bumps.▷In large buildings with right angles and
smooth walls, for example, in underground
garages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, for exam‐
ple, sweeping machines, high pressure
steam cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.
With front PDC: to reduce false alarms, switch
off automatic PDC activation on obstacle detec‐
tion, for example in car washes, refer to
page 135.
Malfunction A Check Control message, refer to page 81, is
displayed in the instrument cluster.
