Collision warning with Full Auto-brake and Pedestrian Detection*
WARNING
•
The camera has the same limitations as
the human eye. In other words, its
"vision is impaired" by adverse weather
conditions such as heavy snowfall,
dense fog, etc. These conditions may
reduce the function of systems that
depend on the camera or cause these
systems to temporarily stop function-
ing.
•
04
Never place any objects, decals, etc.,
on the windshield in front of the camera.
This could reduce or block the camera's
function, and could cause one or more
of the systems that utilize the camera to
stop functioning.
•
Strong sunlight, reflections from the
road surface, ice or snow covering the
road, a dirty road surface, or unclear
lane marker lines may drastically reduce
the camera's capacity to detect the side
of a lane, a pedestrian or another vehi-
cle.

Pedestrians
The system cannot identify all pedestrians
The Collision Warning system can only identify
and detect a pedestrian who is standing
upright. This person can be standing still, walk-
ing or running.
This means that the system has to be able to
identify a person's head, arms, shoulders, legs,
the upper and lower parts of the body and a
person's pattern of movement when walking or
running.
If parts of the body are not visible to the cam-
era, the system cannot detect the pedestrian.
The following conditions apply:
•
In order to detect a pedestrian, the system
must have a full view of the person's entire
I n f o r m a t i o n P r o v i d e d b y :
body and the person must be at least
32 in. (80 cm) tall.
•
The system cannot detect a pedestrian
carrying a large object.
•
The camera's capacity to see a pedestrian
at dawn or dusk is limited, much as it is for
the human eye.
•
The camera's function is deactivated and
will not detect a pedestrian in darkness or
in tunnels, even if there is street lighting in
the area.
WARNING
•
Collision Warning with Full Auto-brake
and Pedestrian Detection is designed to
be a supplementary driving aid. It is not,
however, intended to replace the driv-
er's attention and judgement. The driver
is always responsible for operating the
vehicle in a safe manner.
•
The system cannot detect all pedes-
trians in all situations, such as in dark-
ness/at night and cannot detect parti-
ally hidden pedestrians, people who are
less than approx. 32 in. (80 cm) tall, or
people wearing clothing that obscures
the contours of their bodies.
