Forward Collision-Avoidance Assist (FCA)
system disabled. Camera obscured / Radar blocked
When the sensor cover is blocked with
dirt, snow, or debris, FCA system may
not detect other vehicles. If this occurs, a
warning message will appear on the LCD
display.
The system will operate normally when
such dirt, snow or debris is removed.
FCA may not properly operate in an area
(e.g. open terrain), where any substances
are not detected after turning ON the
vehicle.
Also, even though a warning message
does not appear on the LCD display, FCA
may not properly operate.
WARNING
FCA system may not activate according
to the road conditions, inclement
weather, driving conditions or traffic
conditions.

Check Forward Collision Avoidance Assist system
When FCA is not working properly, FCA
warning light () will illuminate and the
warning message will appear for a few
seconds. After the message disappears,
the master warning light (
) will
illuminate. In this case, have the vehicle
inspected by an authorized HYUNDAI
dealer.
The FCA warning message may appear
along with the illumination of the ESC
(Electronic Stability Control) warning
light. Both FCA warning light and
warning message will disappear once the
ESC warning light issue is resolved.
WARNING
• FCA is only a supplemental system
for the driver's convenience. The
driver should hold the responsibility
to control the vehicle operation. Do
not solely depend on FCA system.
Rather, maintain a safe braking
distance, and, if necessary, depress
the brake pedal to reduce the driving
speed or to stop the vehicle.
• In certain instances and under
certain driving conditions, FCA
system may activate unintentionally.
This initial warning message appears
on the LCD display with a warning chime.
Also due to sensing limitations, in
certain situations, the front radar
sensor or camera recognition
system may not detect the vehicle,
pedestrian or cyclist (if equipped)
ahead. FCA system may not activate
and the warning message may not be
displayed.
• Even if there is any problem with
the brake control function of FCA
system, the vehicle’s basic braking
performance will operate normally.
However, brake control function for
avoiding collision will not activate.

•
The pedestrian or cyclist is not fully
detected by the camera recognition
system, for example, if the pedestrian
is leaning over or is not fully walking
upright
• The pedestrian or cyclist is moving
very quickly or appears abruptly in the
camera detection area
• The pedestrian or cyclist is wearing
clothing that easily blends into the
background, making it difficult to be
detected by the camera recognition
system
• The outside lighting is too bright (e.g.
when driving in bright sunlight or
in sun glare) or too dark (e.g. when
driving on a dark rural road at night)
• It is difficult to detect and distinguish
the pedestrian or cyclist from other
objects in the surroundings, for
example, when there is a group of
pedestrians, cyclists or a large crowd
• There is an item similar to a person’s
body structure
• The pedestrian or cyclist is small
• The pedestrian has impaired mobility
• The sensor recognition is limited •
The radar sensor or camera is blocked
with a foreign object or debris
• Inclement weather such as heavy rain
or snow obscures the field of view of
the radar sensor or camera
• 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
• The windshield glass is fogged up; a
clear view of the road is obstructed
• The adverse road conditions cause
excessive vehicle vibrations while driving
• The sensor recognition changes
suddenly when passing over a speed bump
• You are on a roundabout
• The pedestrian or cyclist suddenly
interrupts in front of the vehicle
• The cyclist in front is riding intersected
with the driving direction
• There is any other electromagnetic
interference
• The construction area, rail or other
metal object is near the cyclist
• The bicycle material is not reflected
well on the radar
WARNING
Turn off Forward Collision avoidance
Assist system through cluster or
infotainment system before towing
a vehicle. Application of FCA system
while towing may adversely affect the
safety of your vehicle or the towing
vehicle.
Use extreme caution when the vehicle
in front of you has cargo that extends
rearward from the cab, or when the
vehicle in front of you has higher
ground clearance.

Do not place objects on the
dashboard that reflects light such as
mirrors, white paper, etc. This may
prevent LKA system from functioning
properly.
• Always have your hands on the
steering wheel while LKA system is
activated. If you continue to drive
with your hands off the steering
wheel after the “Keep hands on
steering wheel” warning message
appears, the system will stop
controlling the steering wheel.
• The steering wheel is not
continuously controlled so if the
vehicle speed is at a higher rate
when leaving a lane the vehicle may
not be controlled by the system. The
driver must always follow the speed
limit when using the system.
• If you attach objects to the steering
wheel, the system may not assist
steering or the hands off alarm may
not work properly.
