1. Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC)
determines the conditions ahead of
the vehicle while traveling at night and
detects traffic lanes. The distance in
which the Forward Sensing Camera
(FSC) can detect objects varies
depending on the surrounding
conditions.
WARNING
Do not modify the suspension:
If the vehicle height or inclination is
changed, the system will not be able to
correctly detect vehicles ahead. This
will result in the system not operating
normally or mistakenly operating,
which could cause a serious accident.
CAUTION

Do not apply accessories, stickers or
film to the windshield near the
Forward Sensing Camera (FSC).
If the area in front of the Forward
Sensing Camera (FSC) lens is
obstructed, it will cause the system
to not operate correctly.
Consequently, each system may not
operate normally which could lead
to an unexpected accident.
 Do not disassemble or modify the
Forward Sensing Camera (FSC).
Disassembly or
modification of the
Forward Sensing Camera (FSC) will
cause a malfunction or mistaken
operation. Consequently, each
system may not operate normally
which could lead to an unexpected
accident.
 Heed the following cautions to
assure the correct operation of the
Forward Sensing Camera (FSC).
 Be careful not to scratch the
Forward Sensing Camera (FSC)
lens or allow it to get dirty.
