System Malfunction
Check Forward Collision Avoidance
Assist system
When the FCA is not workingproperly, the FCA warning light
( ) will illuminate and the warn-
ing message will appear for a few
seconds. After the message dis-
appears, 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 prematurely. This ini-
tial 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 or pedestri-
an ahead. The FCA system
may not activate and the
warning message will not be
displayed.
WARNING 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 a colli-
sion.
The brake control may be
insufficient, possibly causing
a collision, 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 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
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).
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.
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.
The FCA system operates
only to help 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.
WARNING

- Driving on a curve
The performance of the FCA system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the FCA system may activate
prematurely.
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 main-
tain 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 driving
on a curved road.
In this case, the system may unnec-
essarily 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 distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
- Driving on a slope
The performance of the FCA decreas-
es while driving upward or downward
on a slope, not recognizing the vehi-
cle in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the FCA suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.

- Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the FCA sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
- 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.

Blind-Spot Collision-Avoidance Assist
(BCA) system is automatically deacti-
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
(Camera and Radar)

The driver is responsible for
accurate steering.
Do not unnecessarily operate
the steering wheel, when the
Blind-Spot Collision-Avoidance
Assist System is in operation.
Always pay extreme caution
while driving. The Blind-Spot
Collision-Avoidance Assist
system may not operate or
unnecessarily operate in
accordance with your driving
situations.
The Blind-Spot Collision-
Avoidance Assist system is
not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. Pay attention to the road
conditions at all times.
