FCA Warning Message and
System Control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward Collision
Warning include Early or Later initial
warning time.
Collision Warning (First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- Your vehicle speed may deceleratemoderately.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision.
- If you select "Warning Only", the FCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the brake
directly because the FCA system
do not control the brake.
Emergency Braking(Second warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decel-
erate the vehicle.
- The FCA system limitedly controls
the brakes to preemptively mitigate
impact in a collision. The brake
control is maximized just before a
collision.

Driving your vehicle
- If you select "Warning Only", the FCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the brake
directly because the FCA system
do not control the brake.
Brake operation
In an urgent situation, the braking system enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA braking control is auto- matically canceled, when risk fac-
tors disappear.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
If any other warning sound such
as seat belt warning chime is
already generated, the Forward
Collision-Avoidance Assist (FCA)
system warning may not sound.
CAUTION
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
FCA system.
WARNING
The FCA braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING

5-60
Driving your vehicle
NEVER install any accessories or stickers on the front wind-
shield, nor tint the front wind-
shield.
NEVER locate any reflective objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the system.
Pay extreme caution to keep the camera out of water.
NEVER disassemble the camera assembly, nor apply any impact
on the camera assembly.
Playing the vehicle audio sys- tem at high volume may offset
the system warning sounds.
Information

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 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 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 Forward
Collision-Avoidance Assist system
may be limited when driving on a
curved road.
The front camera recognition system
may not detect the vehicle or pedes-
trian traveling in front on a curved
road. This may result in no alarm
and braking 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 a vehicle or
pedestrian in the next lane or outside
the lane when driving 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 recognition may not
detect the vehicle or pedestrian 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 or pedestrian 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.

System Description
Blind-Spot Collision Warning(BCW)
The Blind-Spot Collision Warning
(BCW) system uses radar sensors in
the rear bumper to monitor and warn
the driver of an approaching vehicle
in the driver's blind spot area.
1) Blind-Spot Area
The blind spot detection range varies
relative to vehicle speed.
Note that if your vehicle is traveling
much faster than the vehicles around
you, the warning will not occur. 2) Closing at high speed
The Lane Change Assist feature will
alert you when a vehicle is approach-
ing in an adjacent lane at a high rate
of speed. If the driver activates the
turn signal when the system detects
an oncoming vehicle, the system
sounds an audible alert.
Blind-Spot Collision-Avoidance
Assist (BCA)
The Blind-Spot Collision-Avoidance
Assist (BCA) system helps detect the
front lane through the camera
installed on the upper front wind-
shield and helps detect the side/rear
areas through radar sensors.
The Blind-Spot Collision-Avoidance
Assist system may activate the
Electronic Stability Control (ESC) in
accordance with a colliding possibili-
ty with an approaching vehicle while
changing lanes. It is to help the col-
liding risk or mitigate the colliding
damage.
