Driving your vehicle
Limitation of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle or pedestrians
ahead in the roadway through cam-
era recognition to warn the driver
that a collision is imminent, and if
necessary, apply emergency brak-
ing.
In certain situations, the camera may
not be able to detect the vehicle or
pedestrians ahead. In these cases,
the FCA system 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 camera is covered object or
debris
• Inclement weather such as heavy
rain or snow obscures the field of
view of the camera
• The camera recognition is limited
• 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 trac-
tor, trailer, etc.)
• The camera's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light 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
• When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road.
• The field of view in front is
obstructed by sun glare or head-
light of oncoming vehicle.
• The windshield glass is fogged up.
• The vehicle in front is driving errat-
ically.
• The vehicle is on unpaved or
uneven rough surfaces, or roads
with sudden gradient changes.
• The vehicle is drives inside a build-
ing, such as a basement parking lot
• 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.
• Adverse road conditions cause
excessive vehicle vibrations while
driving
• The sensor recognition changes
suddenly when passing over a
speed bump
