Limitations of the System
The Forward Collision-Avoidance
Assist (FCA) system is designed to
help monitor the vehicle ahead or a
pedestrian in the roadway through
radar signals and camera recognition
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.Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
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.
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.
WARNING

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 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.
Check the surrounding traffic condi-
tions before use.

Driving 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 drivingspeed 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 vehicle in front of you merges
out of the lane, the FCA system may
not immediately detect the new vehi-
cle that is now in front of you. In this
case, you must maintain a safe brak-
ing distance, and if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain 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.
Detecting pedestrians
The sensor may be limited when:
The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very
quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing
that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion 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 from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
There is an item similar to a per-
son's body structure
The pedestrian is small The pedestrian has impaired
mobility
The radar sensor or camera is
blocked with a foreign object or
debris
The camera lens is contaminated
due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel
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

HYUNDAI dealer.
When there is a problem with the
system do one of the following:
Turn the system on after turning
the engine off and on again.
Check if the ignition switch is in the
ON position.
Check if the system is affected by
the weather. (ex: fog, heavy rain,
etc.)
Check if there is foreign matter on
the camera lens.
If the problem is not solved, have
your vehicle checked by an author-
ized HYUNDAI dealer.
The LKA system will not be in the
ENABLED state and/or the steering
wheel will not be assisted when:
The turn signal is turned on before
changing a lane. If you change
lanes without the turn signal on, the
steering wheel might be controlled.
The vehicle is not driven in the mid-
dle of the lane when the system is
turned on or right after changing a
lane.
ESC (Electronic Stability Control) or
VSM (Vehicle Stability Management)
is activated.
The vehicle is driven on a sharp
curve.
Vehicle speed is below 35 mph
(56 km/h) and over 110 mph (177
km/h).
The vehicle makes sharp lane
changes.
The vehicle brakes suddenly.
The lane is very wide or narrow.
There are more than two lane lines
on the road. (e.g. construction area)
Only one side of the lane marker is
detected. Radius of a curve is too small.
The vehicle is driven on a steep
incline.
The steering wheel is turned sud-
denly.
Limitations of the System
The LKA system may operate pre-
maturely even if the vehicle does not
depart from the intended lane, OR,
the LKA system may not warn you if
the vehicle leaves the intended lane
under the following circumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane
marker from the road because the
lane marker is covered with dust or
sand.
It is difficult to distinguish the color
of the lane marker from the road.
There are markings on the road
surface that look like a lane marker
that is inadvertently being detected
by the camera.
The lane marker is indistinct or
damaged.
