Driving your vehicle
Lane changing
A vehicle which moves into your
lane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The radar may not detect immedi-
ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Narrow vehicles such as motorcy-
cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles (When the vehi-
cle ahead drives away, the system
may not detect a stopped vehicle.)
- Vehicles with small rear profile
such as trailers with no loadsA vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
luggage compartment
- While the steering wheel is operat-
ing
- When driving to one side of the
lane
- When driving on narrow lanes or
on curves
Apply the brake or accelerator pedal
if necessary.5

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 driver
should 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 FCA
system.

(Continued)
Be careful not to apply unneces-
sary force on the radar sensor or
sensor cover. If the sensor is
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.
NEVER place any reflective
objects (i.e. white paper, mirror)
over the crash pad. Any light
reflection may prevent the sys-
tem from functioning properly.
Pay extreme caution to keep the
camera dry.
NEVER disassemble the camera
assembly, or apply any impact
on the camera assembly.
Information
We recommend that you have the sys-
tem checked by an authorized
HYUNDAI dealer when:
• The windshield glass is replaced.
• The front radar sensor or cover gets
damaged or replaced.
Warning message and warning
light
Forward Collision-Avoidance Assist
(FCA) system disabled.
Radar blocked
When the sensor cover is blocked
with dirt, snow, or debris, FCA sys-
tem may not detect other vehicles. If
this occurs, a warning message will
appear on the LCD display. Remove
any dirt, snow, or debris and clean
the radar sensor cover before oper-
ating FCA system.
The system will operate normally
when such dirt, snow or debris is
removed.i
NOTICE
OIK057090L

Driving your vehicle
FCA is only a supplemental
system for the driver's con-
venience. The driver should
hold 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 brake
pedal 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 view
camera 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 loose
objects secured.
FCA system may not activate
if the driver applies the brake
pedal to avoid collision.
(Continued)WARNING
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.
(Continued)
WARNING
(Continued)
If a vehicle in front abruptly
stops, the brake control may
not work possibly causing a
collision.
Occupants may get injured, if
the vehicle abruptly stops by
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 15
seconds 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 or
coated 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.) (Continued)
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 end
street.
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 or to stop the
vehicle.

Driving your vehicle
The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the front view cam-
era recognition system (for exam-
ple a tractor trailer, etc.)
The front view 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 vehicle in front does not have
their rear lights or their rear lights
does not turned ON or their rear
lights are located unusually
The outside brightness changes
suddenly, for example when enter-
ing or exiting 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 obstruct-
ed by sun glare or head light of
oncoming vehicle
The windshield glass is fogged up; a
clear view of the road is obstructed The vehicle in front is driving errati-
cally
The vehicle is on unpaved or
uneven rough surfaces, or road
with sudden gradient changes
The vehicle is driven near areas
containing metal substances as a
construction zone, railroad, etc.
The vehicle drives inside a building,
such as a basement parking lot
The front view camera does not
recognize the entire vehicle in front
The front view 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
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 obstructed The rear part of the vehicle in front
is not normally visible. (the vehicle
turns in other direction or the vehi-
cle is overturned.)
The adverse road conditions cause
excessive vehicle vibrations while
driving
The sensor recognition changes
suddenly when passing over a
speed bump
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
You are on a roundabout and the
vehicle in front circles

Driving on a curve
The performance of Forward
Collision-Avoidance Assist system
may be limited when driving on a
curved road.
The front view camera or front
radar sensor recognition system
may not detect the vehicle, pedes-
trian or cyclist 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 neces-
sary, depress the brake pedal to
reduce your driving speed in order
to maintain a safe distance.
Forward Collision-Avoidance Assist
system may recognize a vehicle or
pedestrian or cyclist 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 view camera or front
radar sensor recognition may not
detect the vehicle, 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.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, Forward Collision-
Avoidance Assist system may not
immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. In this case, you
must maintain a safe braking dis-
tance, 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 vehicle in front of you merges
out of the lane, Forward Collision-
Avoidance Assist system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking dis-
tance, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance. 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. Forward Collision-
Avoidance Assist system may not
be able to detect the cargo extend-
ing from the vehicle. In these
instances, you must maintain a
safe braking distance from the
rearmost object, and if necessary,
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 front view camera
recognition 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 front view 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 front view
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, cyclists or a large
crowd

detect and monitor the vehicle
ahead or detect a pedestrian
or cyclist (if equipped) in the
roadway through radar sig-
nals and camera recognition.
It is not designed to detect
bicycles, motorcycles, or
smaller wheeled objects such
as luggage bags, shopping
carts, or strollers.
