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.

5-56
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 your vehicle
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

Driving your vehicle
Lane Keeping Assist system helps
detect lane markers on the road with
a front view camera at the front
windshield, and assists the driver's
steering to help keep the vehicle
between lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a slight counter-
steering torque, trying to help pre-
vent the vehicle from moving out of
its lane.

Lane Keeping Assist system is
not a substitute for safe driving
practices, but a convenience
function only. It is the responsi-
bility of the driver to always be
aware of the surroundings and
steer the vehicle.
WARNING
Take the following precautions
when using Lane Keeping
Assist system :
Do not turn the steering wheel
suddenly when the steering
wheel is being assisted by the
system.
LKA system helps to prevent
the driver from moving out of
the lane unintentionally by
assisting the driver's steering.
However, the driver should
not solely rely on the system
but always pay attention on
the steering wheel to stay in
the lane.
The operation of LKA system
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
(Continued)
WARNING

(Continued)
The system detects lane
markers and controls the
steering wheel by a front view
camera, therefore, if the lane
markers are hard to detect,
the system may not work
properly.
Please refer to "Limitations of
the System".
Do not remove or damage the
related parts of LKA system.
You may not hear a warning
sound of LKA system if the
audio volume is high.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. This may prevent LKA
system from functioning
properly.
When the lane markers are
hard to detect, please refer to
"Driver's Attention".
(Continued)(Continued)
Always have your hands on
the steering wheel while LKA
system is activated. If you
continue to drive with your
hands off the steering wheel
after the "Keep hands on
steering wheel" warning mes-
sage appears, the system will
stop controlling the steering
wheel.
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
rate when leaving a lane the
vehicle may not be controlled
by the system. The driver
must always follow the speed
limit when using the system.
If you attach objects to the
steering wheel, the system
may not assist steering or the
hands off alarm may not work
properly.
When you tow a trailer, make
sure that you turn off LKA
system.(Continued)
Do not disassemble LKA sys-
tem camera temporarily to
tint the window or attach any
types of coatings and acces-
sories. If you disassemble the
camera and assemble it again,
we recommend that you take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.
When you replace the wind-
shield glass, LKA system
camera or related parts of the
steering wheel, we recom-
mend that you take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked for calibration.
