visibility (smog, smoke, dust, fog,
heavy rain, snow, etc.).
• When the windshield visibility is
poor. WARNING
• Do not attempt to disassemble
the front view camera without the
assistance of an authorized HYUNDAI
dealer technician. If the front camera
is removed for any reason, the
system may need to be re-calibrated.
Have the system inspected by an
authorized HYUNDAI dealer.
• If the windshield of your vehicle is
replaced, most likely the front view
camera will need to be re-calibrated.
If this occurs, have your vehicle
inspected and have the system re-
calibrated by an authorized HYUNDAI
dealer.
• Be careful that water doesn’t get into
High Beam Assist unit and do not
remove or damage related parts of
High Beam Assist system.
• Do not place objects on the crash
pad that reflect light such as mirrors,
white paper, etc. The system may
malfunction if sunlight is reflected.
• At times, High Beam Assist system
may not work properly. The system
is for your convenience only. It is the
responsibility of the driver for safe
driving practices and always check
the road conditions for your safety.
• When the system does not operate
normally, change the headlamp
position manually between the high
beam and low beam.

FCA Sensor
Front view cameraFront view camera
ODN8A069024ODN8A069024
Front radarFront radar
ODN8A069023ODN8A069023
These sensors detect frontal vehicles,
pedestrian and cyclist.
In order for FCA system to operate
properly, always make sure the sensor
cover or sensor is clean and free of dirt,
snow, and debris.
Dirt, snow, or foreign substances on the
sensor cover or sensor may adversely
affect the sensing performance of the
sensor. Always keep these clean.
 Refer to “Lane Keeping Assist (LKA)” for cautions for the front camera.
NOTICE
• Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
cover clean and free of dirt and
debris.
• Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, FCA system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, FCA system may not
operate properly. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• Use only genuine parts to repair or
replace a damaged sensor or sensor
cover. Do not apply paint to the
sensor cover.

While Driving6-48
• 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.

Forward Collision-Avoidance Assist
system may recognize a vehicle or
pedestrian or cyclist in the next lane
or outside the lane when driving on a
curved road.
If this occurs, the system may
unnecessarily alarm the driver and
apply the brake.
Always pay attention to road and
driving conditions, while driving.

While Driving6-58
Limitations of the system
FCA-Junction Turning function is only a
supplemental system for driver’s safety
whilst turning left on the crossroads. The
driver should hold the responsibility to
control the vehicle. The system monitors
the oncoming vehicle ahead the road
through the front view camera and
radar. In certain situations, the front view
camera and radar may not be able to
detect the oncoming vehicles properly.
The driver must pay careful attention
in the following situations where the
system operation may be limited or it
may activate unintentionally.
The sensor may be limited when:
• The radar sensor or camera r
ecognizes the approaching vehicle
too late.
• The radar sensor or camera is blocked with a foreign object or debris.
• The driving direction of the approaching vehicle is irregular or
frontal.
• The approaching vehicle changes lanes too late or decelerates suddenly.
• The angle of the approaching vehicle is out of range.
• Whilst circling, the sensor (the front view camera or front radar) does not
detect the approaching vehicle.
• The driving speed of the approaching vehicle is too fast or slow.
• The head lamps of the approaching vehicle are turned off or asymmetrical. • The approaching vehicle stops whilst
turning left.
• The vehicle moves out of its lane or returns to its lane.
• The vehicle changes lanes suddenly at a low speed whilst there is an
approaching vehicle.
• The brightness outside is too so it does not detect the vehicle.
• Inclement weather such as heavy rain or snow obscures the field of view of
the front view camera or front radar.
• The approaching vehicle is covered with snow.
• The field of view in front is obstructed by sun glare.
• The shape of approaching vehicle is unusual.
• Whilst driving upward or downward on a slope.
For more information, refer to “Forward
Collision-Avoidance Assist (FCA)” in this
chapter.
