• The radar sensor or cover gets dam-aged or replaced.
Warning message and warninglight
Forward Collision Avoidance Assist
(FCA) system disabled.
Radar blocked
When the sensor cover is blocked
with dirt, snow, or debris, the FCA
system operation not be able to
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
objects or vehicles are not detected
after turning on the engine.
System Malfunction
Check Forward Collision Avoidance
Assist system
When FCA is not working properly,
the FCA warning light ( ) will illu-
minate and the warning message
will appear for a few seconds. After
the message disappears, the mas-
ter warning light ( ) will illumi-
nate. 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 warn-
ing message will disappear once
the ESC warning light issue is
resolved.
FCA is only a supplemental
system for the driver's con-
venience. It is the driver's
responsibility to control the
vehicle operation. Do not
solely depend on the 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 condi-
tions, the FCA system may
activate prematurely. This ini-
tial warning message appears
on the LCD display with a
warning chime.
WARNING
Also due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The FCA system
may not activate and the
warning message may not be
displayed.
If there is a malfunction with
the FCA system, the Forward
Collision avoidance assist
system is not applied even
though the braking system is
operating normally.
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.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate 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.
The FCA system may not acti-
vate according to the road
conditions, inclement weath-
er, driving conditions or traffic
conditions.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system does not
detect all vehicles.

Limitations of the System
The Forward Collision Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian on the roadway through
radar signals and camera recogni-
tion to warn the driver that a collision
is imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
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.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked 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
There is interference by electro- magnetic waves
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance or to stop the
vehicle.
The FCA system operates
only to detect vehicles or
pedestrians in front of the
vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street).

The vehicle is on unpaved oruneven rough surfaces, or road
with sudden gradient changes.
The vehicle drives through a con- struction area, on an unpaved
road, or above metal materials,
such as a railway
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The camera's field of view is not well illuminated (either too dark or
too much reflection or too much
backlight that obscures the field of
view)
The camera does not recognize the entire vehicle in front.
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 tractor
trailer, etc.)
The vehicle in front does not have rear lights or the rear lights are not
turned ON or the rear lights are
located unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel The vehicle drives inside a build-
ing, such as a basement parking
lot
The adverse road conditions cause excessive vehicle vibrations while
driving
You are on a roundabout and the vehicle in front circles
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
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.
Light coming from a street light or an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
The field of view in front is obstructed by sun glare
The shadow is on the road by a median strip, trees, etc.
The vehicle drives through a toll- gate. The windshield glass is fogged up;
a clear view of the road is obstruct-
ed
The radar/camera sensor recogni- tion is limited
The rear part of the vehicle in front is not normally visible (for example,
the vehicle is spinning or the vehi-
cle is overturned)
There is severe irregular reflection from the radar sensor
The sensor recognition changes suddenly when passing over a
speed bump
The vehicle in front is driving errat- ically
The vehicle in front is moving verti- cally to the driving direction
The vehicle in front is stopped ver- tically
The vehicle in front is driving towards your vehicle or reversing

Driving your vehicle
Driving on a curve The performance of the FCA sys-
tem may be limited when driving
on a curved road.
This may cause the alarm or brak-
ing to activate or not activate
improperly.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must
maintain a safe braking distance,
and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance. The FCA system may recognize a
vehicle in the next lane when driv-
ing on a curved road.
In this case, the system may
unnecessarily alarm the driver and
apply the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake
pedal to reduce your driving speed
in order to maintain a safe dis-
tance.
Also, when necessary depress the
accelerator pedal to prevent the
system from unnecessarily decel-
erating your vehicle.
Check the road conditions for safe
operation of the FCA system. Driving on a slope
The performance of the FCA
decreases while driving upward or
downward on a slope, not recog-
nizing the vehicle in front in the
same lane. It may unnecessarily
produce the warning message and
the warning alarm, or it may not
produce the warning message and
the warning alarm at all.
When the FCA suddenly recog-
nizes the vehicle in front while
passing over a slope, you may
experience sharp deceleration.

Detecting the vehicle in front of you If 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, additional special atten-
tion is required. The FCA system
may not be able to detect the cargo
extending from the vehicle. In
these instances, you must main-
tain a safe braking distance from
the rearmost object, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order
to maintain distance.
Detecting pedestrians
The sensor may be limited when:
The pedestrian is not fully detectedby the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
If the bicycle material is not reflect- ed well on the radar
When the pedestrian or cyclist suddenly interrupts in front of the
vehicle
When there is any other electro- magnetic interference
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 distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
There is an item similar to a per- son's body structure
The pedestrian 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
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
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel
