Limitations of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead in the road-
way through camera recognition to
warn the driver that a collision is immi-
nent, and if necessary, apply emer-
gency braking.
In certain situations, the camera may
not be able to detect the vehicle
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.
• The camera is blocked with a for-
eign 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 camera
• The camera sensor recognition is
limited

reflected on a wet road surface
such as a puddle in the road
• The vehicle drives through a toll-
