Prerequisite for activation
FCA gets ready to be activated,
when 'Active Assist' or 'Warning
Only' under Forward Safety is select-
ed in the cluster LCD display, and
when the following prerequisites aresatisfied.
- ESC (Electronic Stability Control)is on.
- Vehicle speed is over 8 km/h (5 mph). (FCA is only activated within
a certain speed range.)
- The system detects a pedestrian, cyclist (if equipped) or a vehicle in
front, which may collide with your
vehicle. However, FCA may not be
activated or may only sound a
warning alarm depending on the
driving or vehicle conditions.
The FCA may not operate properly according to the frontal situation,
the direction of pedestrian orcyclist (if equipped) and speed.
FCA warning message and
brake control
FCA produces warning messages,
warning alarms, and emergency
braking based on the level of risk ofa frontal collision, such as when a
vehicle ahead suddenly brakes, orthe system detects that a collision
with a pedestrian or cyclist (ifequipped) is imminent.To avoid driver distractions, do not attempt to set or can-cel FCA while driving the vehi-
cle. Always completely stop
the vehicle at a safe place
before setting or cancelingthe system.
FCA automatically activates
when the POWER button is in
the ON position. The driver
can deactivate FCA by cancel-ing the system setting on the
LCD display.
FCA automatically deactivates upon canceling the ESC
(Electronic Stability Control).When the ESC is canceled,
FCA cannot be activated on
the LCD display. In this situa-
tion, the FCA warning light will
illuminate which is normal.
WARNING

Driving your vehicle
Collision Warning (First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle. If FCA detects a vehicle in front,
the system operates when your
vehicle speed is between 8 km/h (5mph) and 180 km/h (110 mph).
Maximum vehicle speed maydecrease depending on the condi-
tion of the vehicle ahead and sur-
roundings.
If FCA detects a pedestrian or cyclist in front, the system operates
when your vehicle speed is
between 8 km/h (5 mph) and 70
km/h (45 mph). Maximum vehicle
speed may decrease depending
on the condition of the pedestrian
or cyclist ahead and surroundings.
If you select 'Warning Only' for the system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will 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 to help
decelerate the vehicle.

If FCA detects a vehicle in front,the system operates when your
vehicle speed is above 8 km/h (5mph) and less than or equal to 180
km/h (110 mph). Maximum vehicle
speed may decrease depending
on the condition of the vehicle
ahead and surroundings.
If FCA detects a pedestrian or cyclist in front, the system operates
when your vehicle speed is
between 8 km/h (5 mph) or aboveand under 70 km/h (45 mph).
Maximum vehicle speed maydecrease depending on the condi-
tion of the pedestrian or cyclist
ahead and surroundings.
If you select 'Warning Only' for the system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will not control the brake.Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
FCA provides additional braking 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 brake control is automat- ically canceled, when risk factors
disappear.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from FCA system.
After the brake control is acti-
vated, the driver must immedi-
ately depress the brake pedal
and check the surroundings.
The brake activation by the
system lasts for about 2 sec-onds.
If any other warning sound
such as seat belt warning
chime is already generated,
Forward Collision-Avoidance
Assist system warning maynot sound.
Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearingthe system warning sounds.

Driving your vehicle
FCA sensor (Front view
camera+ Front radar)
Sensors that detect vehicles ahead,
pedestrians and cyclists.
In order for FCA system to operate
properly, always make sure the sen-
sor cover or sensor is clean and free
of dirt, snow, and debris.Dirt, snow, or foreign substances on
the sensor cover or sensor may
adversely affect the sensing perform-
ance of the sensor.
Do not apply license plate frame
or foreign objects such as a
bumper sticker or a bumper
guard near the front radar sen-
sor. Doing so may adversely
affect the sensing performance
of the front radar.
Always keep the front radar sen- sor and cover clean and free of
dirt and debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
(Continued)
NOTICE
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The drivershould hold the responsibility
to safely drive and control the
vehicle.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehi-
cle, pedestrian or cyclist (if
equipped) ahead, the speed of
the vehicle ahead, and the dri-
ver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of FCAsystem.

forcibly moved out of proper
alignment, FCA system may not
operate correctly. In this case, a
warning message may not be
displayed. We recommend that
you have the vehicle inspected
by an authorized HYUNDAI deal-
er.
If the front bumper becomes damaged in the area around the
front radar sensor, FCA system
may not operate properly. We
recommend that you have the
vehicle inspected by authorized
HYUNDAI dealer.
Use only genuine parts to repair or replace a damaged sensor or
sensor cover. Do not apply paint
to the sensor cover. NEVER install any accessories
or stickers on the front wind-
shield, or tint the front wind-shield.

FCA is only a supplemental
system for the driver's con-
venience. The driver shouldhold the responsibility to con-
trol the vehicle operation. Do
not solely depend on FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brakepedal to reduce the driving
speed or to stop the vehicle.
In certain instances and
under certain driving condi-
tions, FCA system may acti-
vate unintentionally. This ini-
tial warning message appears
on the LCD display with a
warning chime. Also due to sensing limita-
tions, in certain situations, the
front radar sensor or front viewcamera recognition system
may not detect the vehicle,
pedestrian or cyclist ahead.
FCA system may not activate
and the warning message may
not be displayed.(Continued)
(Continued)
Even if there is any problem
with the brake control func-
tion of FCA system, the vehi-
cle's basic braking perform-
ance will operate normally.
However, brake control func-
tion 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.
FCA system may activate dur-
ing braking and the vehicle
may stop suddenly shifting
loose objects toward the pas-
sengers. Always keep looseobjects secured.
FCA system may not activate if the driver applies the brake
pedal to avoid collision.
(Continued)
WARNING (Continued)
If a vehicle in front abruptly
stops, the brake control may
not work possibly causing acollision.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
FCA system operates only when the system detects vehi-
cles, pedestrian, or cyclist
directly in front of the vehicle.

Limitations of the system
Forward Collision-Avoidance Assist system is designed to monitor the
vehicle ahead or a pedestrian or
cyclist in the roadway through front
view camera and radar signals recog-
nition to warn the driver that a colli-
sion is imminent, and if necessary,
apply emergency braking.
In certain situations, the front view
camera or the front radar sensor may
not be able to detect the vehicle,
pedestrian or cyclist ahead. In these
cases, FCA system may not operate
normally. The driver must pay careful
attention in the following situations
where the FCA operation may be lim-ited.
Detecting vehicles
The sensor may be limited when:
The system may not operate for 15seconds after the vehicle is started
or the front view camera is initial-
ized
The front view camera or front radar sensor is covered with a for-
eign object or debris
The front view camera lens is con- taminated due to tinted, filmed orcoated windshield, damaged
glass, or stuck of foreign matter
(sticker, bug, etc.) on the glass
Inclement weather such as heavy rain or snow obscures the field of
view of the front view camera or
front radar sensor
There is interference by electro- magnetic waves
There is severe irregular reflection from the front radar sensor
The front view camera/front radar sensor recognition is limited
The vehicle in front is too small to be detected (for example a motor-cycle etc.)
FCA system does not operate
when the vehicle is in reverse.
FCA system is not designed to detect other objects on the
road such as animals.
FCA system does not detect
vehicles in the opposite lane.
FCA system does not detect
cross traffic vehicles that are
approaching.
FCA system cannot detect
vehicles that are stopped ver-
tically to your vehicle at a
intersection or dead endstreet.
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 thebrake pedal to reduce the driv-
ing speed in order to maintain a
safe distance or to stop the
vehicle.
