Pedestrian detection
Warm objects that are similar in shape to human
beings are detected by the system.
People detected by the system are displayed
with a slight yellow hue.
Under good ambient conditions, the pedestrian
detection system operates within a range of ap‐
prox. 50 ft/15 m to approx. 330 ft/100 m.
Warning of people in danger
If the system detects a person in a defined area
in front of the vehicle and if a collision with this
person is imminent, a warning symbol appears
in the Control Display and Head-up Display*.
The warning area in front of the vehicle is divided
into two areas.
▷
Central area 1 directly in front of the vehicle.
▷
Expanded area 2 to the right and left.
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 in‐
creases, the area becomes longer and wider, for
example.
This symbol is displayed when a person
is detected in the central area, arrow 1,
immediately in front of the vehicle.
This symbol is displayed when a person
detected in the extended area, arrow 2,
is moving from the right or left to the
central area.
The symbols in the Head-up Display* corre‐
spond to the symbols in the Control Display. For
people located in the central area, the distance
to the person is indicated by the size of the sym‐
bol.
Although both the shape and the heat radiation
are analyzed, false warnings cannot be ruled out.
System limits
Animals are not detected by the pedestrian de‐
tection function, even if they are clearly visible in
the image.

the following:
▷
On steep hills, in steep depressions or in
tight curves.
▷
When the camera is dirty or the protective
glass is damaged.
▷

especially when their heads are covered.
