Limitations of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a pedes-
trian in the roadway through radar sig-
nals and camera recognition to warn
the driver that a collision is imminent,
and if necessary, apply emergency
braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
• The radar sensor or camera is
blocked with a foreign object or
debris
• The camera lens is contaminated
due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
• Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
• There is interference by electro-
magnetic waves
• There is severe irregular reflection
from the radar sensor
• The radar/camera sensor recogni-
tion is limited
• The camera does not recognize
the entire vehicle in front.
• The camera is damaged.
• The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
• The shadow is on the road by a
median strip, trees, etc.
• The vehicle drives through a toll-
gate.
• The rear part of the vehicle in front
is not normally visible. (the vehicle
turns in other direction or the vehi-
cle is overturned.)
• The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.)
• The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
• The camera's field of view is not
well illuminated (either too dark or
too much reflection or too much
backlight that obscures the field of
view)
• The vehicle in front does not have
their rear lights properly turned ON
or their rear lights are located
unusually.
• The outside brightness changes
suddenly, for example when enter-
ing or exiting a tunnel
