System Malfunction
Check Forward Collision Avoidance
Assist system
When the FCA is not working prop-
erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, 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.
The FCA is only a supplemen-
tal system for the driver’s con-
venience. The driver should
hold the responsibility to con-
trol 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.
In certain instances and
under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
or cyclists ahead. The FCA
system may not activate and
the warning message will not
be displayed.
WARNING Even if there is any problem
with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
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 a colli-
sion.
The brake control may not
work, possibly causing a colli-
sion, if a vehicle in front
abruptly stops. Always pay
extreme caution.

Limitations of the System
The Forward Collision Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian or cyclists on the roadway
through radar signals and camera
recognition to warn the driver that a
collision is imminent, and if neces-
sary, apply emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle, a pedestrian or
cyclists ahead. In these cases, the
FCA system may not operate nor-
mally. 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 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
There is interference by electro-
magnetic waves
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 FCA system cannot
detect the cross traffic cyclist
that are approaching.
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.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates
only to detect vehicles, pedes-
trian or cyclist in front of 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.

- Driving on a curve
The performance of Forward
Collision-Avoidance Assist system
may be limited when driving on a
curved road.
The front camera or radar sensor
recognition system may not detect
the vehicle, pedestrian or cyclist trav-
eling in front on a curved road.
This may result in no alarm and brak-
ing 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 main-
tain a safe distance.Forward Collision-Avoidance Assist
system may recognize in the next
lane or outside the lane when driv-
ing on a curved road.
If this occurs, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving.- Driving on a slope
The performance of Forward
Collision-Avoidance Assist system
may be decreased while driving
upward or downward on a slope. The
front camera or front radar sensor
recognition may not detect the vehi-
cle, pedestrian or cyclist in front.
This may result in unnecessary
alarm and braking or no alarm and
braking when necessary.
When the system suddenly recog-
nizes the vehicle, pedestrian or
cyclist 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, addi-
tional special attention is required.
The FCA system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians or
cyclists
The sensor may be limited when:
The pedestrian or cyclist is not fully
detected by the camera recogni-
tion 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 wear-
ing 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 distin-
guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclist or a large
crowd There is an item similar to a per-
son'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 obstruct-
ed
The adverse road conditions cause
excessive vehicle vibrations while
driving
When the pedestrian or cyclist
suddenly interrupts in front of the
vehicle

vated when:
- The vehicle drives a certain dis-
tance away
- The vehicle direction is changed
against the possible-colliding point
- The steering wheel is abruptly
moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in
the middle of the vehicle lanes to
keep the system in the ready status.
When the vehicle drives too close to
one side of the vehicle lanes, the
system may not properly operate.
In addition, the system may not prop-
erly control your vehicle in accor-
dance with driving situations. Thus,
always pay close attention to road
situations.Detecting Sensor
