If the vehicle in front stops suddenly,
you may have less control of the
brake system. Therefore, always keep
a safe distance between your vehicle
and the vehicle in front of you.
• FCA system may activate during
braking and the vehicle may stop suddenly shifting loose objects
toward the passengers. Always keep
loose objects secured and fasten the
seat belt.
• FCA system may not activate if the
driver applies the brake pedal to
avoid collision.
• The brake control may be
insufficient, possibly causing a
collision, if a vehicle in front abruptly
stops. Always pay extreme caution.
• Occupants may get injured, if
the vehicle abruptly stops by the
activated FCA system. Pay extreme caution.
• FCA system operates only when the
system detect vehicles, pedestrian or
cyclist in front of the vehicle.
• FCA system may not activate
according to road conditions,
inclement weather, driving
conditions or traffic conditions.
• FCA system may not work for all
vehicles, passengers or cyclists.
WARNING
• FCA system does not operate when
the vehicle is in reverse.
• FCA system is not designed to detect
other objects on the road such as animals.
• FCA system does not detect vehicles
in the opposite lane.
• FCA system does not detect cross
traffic vehicles that are approaching.
• FCA system cannot detect vehicles
that are stopped vertically to your
vehicle at a intersection or dead end
street.
• FCA system cannot detect the cross
traffic cyclist that are approaching.
In these cases, you must maintain a
safe braking distance, and if necessary,
depress the brake pedal to reduce the
driving speed in order to maintain a
safe distance or to stop the vehicle.
Limitations of the System
Forward Collision avoidance assist
system is designed to monitor the
vehicle ahead or a pedestrian or cyclist
in the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent, and if
necessary, apply emergency braking.
In certain situations, the radar sensor
or the camera may not be able to
detect the vehicle, pedestrian or cyclist
ahead. In these cases, FCA system may
not operate normally. The driver must
pay careful attention in the following
situations where FCA operation may be
limited.

• Driving on a curve
The performance of Forward Collision-
Avoidance Assist system may be
limited when driving on a curved road.
The front view camera or radar sensor
recognition system may not detect the
vehicle, pedestrian or cyclist traveling
in front on a curved road. This may
result in no alarm and braking when
necessary.
Always pay attention to road and
driving conditions, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain a safe distance.

Forward Collision-Avoidance
Assist - Junction Turning (if equipped)
FCA-Junction Turning function is
designed to reduce the risk of collision
by detecting and monitoring the
oncoming vehicle ahead. When the
vehicle turns to the left at a junction, the
system recognises the oncoming vehicle
ahead in advance with the front view
camera and the front radar. It produces
warning messages or haptic warning
alarms in accordance with the collision
risk levels.
