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. 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 risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
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 camera viewing field or the front
windshield are dirty or covered.
Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.
During calibration of the camera immedi‐
ately after vehicle shipment.
If there is constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
When it is dark outside.
Lane departure warning
The concept
Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
