The camera’s limitations
The camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 166), and Lane Departure Warning (see
page 169).
NOTE
• To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.
• Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.
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.
• 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
