When FCA is not working properly, FCA
warning light () will illuminate and the
warning message will appear for a few
seconds. After the message disappears,
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. Both FCA warning light and
warning message will disappear once the
ESC warning light issue is resolved.
WARNING
• FCA is only a supplemental system
for the driver's convenience. The
driver should hold the responsibility
to control 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 conditions, FCA
system may activate unintentionally.
This initial warning message appears
on the LCD display with a warning chime.
Also due to sensing limitations, in
certain situations, the front radar
sensor or camera recognition
system may not detect the vehicle,
pedestrian or cyclist (if equipped)
ahead. FCA system may not activate
and the warning message may not be
displayed.
• Even if there is any problem with
the brake control function of FCA
system, the vehicle’s basic braking
performance will operate normally.
However, brake control function for
avoiding collision will not activate.

• Changing lanes
When a vehicle changes lanes in
front of you, FCA system may not
immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. In this case, you must
maintain a safe braking distance, and
if necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
OHI058308L
When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, FCA system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking
distance, and if necessary, depress
the brake pedal to reduce your driving
speed in order to maintain a safe
distance.
ODN8A069200
• 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 attention is required. 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 necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.

WARNING
FCA-Junction Turning function
only activates for vehicles except
pedestrians, two wheel vehicles,
animals or obstacles.
WARNING
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
FCA-Junction Turning function operates
in accordance with the collision risk
levels based on certain parameters
such as the condition, driving direction
and speed of the approaching vehicle.
Never deliberately drive dangerously to
activate the system. Limitations of the system
FCA-Junction Turning function is only a
supplemental system for driver’s safety
whilst turning left on the crossroads. The
driver should hold the responsibility to
control the vehicle. The system monitors
the oncoming vehicle ahead the road
through the front view camera and
radar. In certain situations, the front view
camera and radar may not be able to
detect the oncoming vehicles properly.
The driver must pay careful attention
in the following situations where the
system operation may be limited or it
may activate unintentionally.The sensor may be limited when:
•
The radar sensor or camera
recognizes the approaching vehicle
too late.
• The radar sensor or camera is blocked
with a foreign object or debris.
• The driving direction of the
approaching vehicle is irregular or
frontal.
• The approaching vehicle changes
lanes too late or decelerates suddenly.
• The angle of the approaching vehicle
is out of range.
• Whilst circling, the sensor (the front
view camera or front radar) does not
detect the approaching vehicle.
• The driving speed of the approaching
vehicle is too fast or slow.
• The head lamps of the approaching
vehicle are turned off or asymmetrical.

Lane Keeping Assist system detect lane
markers on the road with a 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 warning, while
applying a counter-steering torque,
trying to help prevent the vehicle from
moving out of its lane.
WARNING
Lane Keeping Assist system is not a
substitute for safe driving practices, but
a convenience function only. It is the
responsibility 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
(or road) 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.
• Do not disassemble LKA system
camera temporarily to tint the
window or attach any types of
coatings and accessories. If you
disassemble the camera and
assemble it again, have the vehicle
inspected by an authorized HYUNDAI
dealer and have the system checked
for calibration.
• When you replace the windshield
glass, LKA system camera or related
parts of the steering wheel, have the
vehicle inspected by an authorized
HYUNDAI dealer and have the system
checked for calibration.
• The system detects lane markers
and controls the steering wheel
by a camera, therefore, if the lane
markers are hard to detect, the
system may not work properly.
Please refer to “Limitations of the
S y s t e m ”.
• 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.

LKA system is disabled temporarily
If the driver still does not have their
hands on the steering wheel after the
message “Keep hands on steering
wheel”, the system will not control the
steering wheel and warn the driver
only when the driver crosses the lane
markers.
However, if the driver has their hands on
the steering wheel again, the system will
start controlling the steering wheel.
WARNING
• LKA system is a supplemental system
only. It is the responsibility of the
driver to safely steer the vehicle and
to maintain it in its lane.
• Turn off LKA system and drive
without using the system in the
following situations:
- In bad weather
- In bad road conditions
- When the steering wheel needs
to be controlled by the driver
frequently
Information
Even though the steering is assisted by the
system, the driver can still steer to control the steering wheel.
The steering wheel may feel heavier when the steering wheel is assisted by the system than when it is not.
