WARNING
Forward Collision-Avoidance Assist-
Junction Turning only activates for
vehicles except pedestrians, two wheel
vehicles, animals or obstacles.
WARNING
Forward Collision-Avoidance Assist
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
Forward Collision-Avoidance
Assist-Junction Turning 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 Forward Collision-
Avoidance Assist
Junction Turning is only a supplemental
function for driver’s safety whilst turning
left on the crossroads. The driver should
hold the responsibility to control the
vehicle. Forward Collision-Avoidance
Assist 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 Forward Collision-Avoidance
Assist 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.

• The approaching vehicle stops whilst
turning left.
• The vehicle moves out of its lane or
returns to its lane.
• The vehicle changes lanes suddenly
at a low speed whilst there is an
approaching vehicle.
• The brightness outside is too so it
does not detect the vehicle.
• Inclement weather such as heavy rain
or snow obscures the field of view of
the front view camera or front radar.
• The approaching vehicle is covered
with snow.
• The field of view in front is obstructed
by sun glare.
• The shape of approaching vehicle is
unusual.
• Whilst driving upward or downward
on a slope.

Lane Keeping Assist 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 Lane Keeping Assist 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 Lane Keeping
Assist.
• Lane Keeping Assist 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 Lane Keeping Assist but
always pay attention on the steering
wheel to stay in the lane.
• The operation of Lane Keeping
Assist can be cancelled or not work
properly according to road condition
and surroundings. Always be
cautious when driving.
• Do not disassemble Lane Keeping
Assist 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 Lane Keeping Assist
checked for calibration.
LANE KEEPING ASSIST (LKA)

06
6-59
• When you replace the windshield
glass, front view camera or related
parts of the steering wheel, have the
vehicle inspected by an authorized
HYUNDAI dealer and have the system
checked for calibration.
• Lane Keeping Assist 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 Lane Keeping Assist.
• You may not hear a warning sound
of Lane Keeping Assist 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 Lane Keeping Assist from
functioning properly.
• Always have your hands on the
steering wheel while Lane Keeping
Assist is activated. If you continue
to drive with your hands off the
steering wheel after the “Keep hands
on steering wheel” warning message
appears, Lane Keeping Assist will
stop controlling the steering wheel.
• The steering wheel is not
continuously controlled so if the
vehicle speed is at a higher rate
when leaving a lane the vehicle may
not be controlled by Lane Keeping
Assist. The driver must always follow
the speed limit when using Lane
Keeping Assist.
• If you attach objects to the steering
wheel, Lane Keeping Assist may not
assist steering or the hands off alarm
may not work properly.

Lane Keeping Assist Operation
ODN8069059ODN8069059
To activate/deactivate Lane Keeping
Assist:
With the ignition switch in the ON
position, press Lane Safety button
located on the instrument panel on the
left hand side of the steering wheel.
The
indicator in the cluster
display will initially illuminate white. This
indicates Lane Keeping Assist is in the
READY but NOT ENABLED state.
Note that the vehicle speed
must be at least approximately
40 mph (64 km/h) to ENABLE
Lane Keeping Assist. The
indicator in the cluster display
will illuminate green.
- White: Sensor does not detect lane
markers or vehicle speed is under 40
mph (64 km/h).
-Green: Sensor detects lane markers
and Lane Keeping Assist is able to
control vehicle steering.
Information
If the indicator (white) is activated from
the previous ignition cycle, Lane Keeping
Assist will turn ON without any additional
control. If you press the Lane Safety
button again, the indicator on the cluster
goes off.
Lane Keeping Assist Function
Change
The driver can change Lane Keeping
Assist to Lane Departure Warning or
Lane Keeping Assist from the LCD
display or infotainment system display(if
equipped). Go to the ‘User Settings →
Driver Assistance → Lane Safety → Lane
Keeping Assist/Lane Departure Warning/
Off'. Lane Keeping Assist is automatically
set to Lane Keeping Assist if a function is
not changed.
Lane Keeping Assist
The Lane Keeping Assist mode guides
the driver to help keep the vehicle within
the lanes. It rarely controls the steering
wheel, when the vehicle drives well
inside the lanes. However, it starts to
control the steering wheel, when the
vehicle is about to deviate out of the
lanes.
Lane Departure Warning
Lane Departure Warning alerts the driver
with a visual warning and a warning
alarm when Lane Departure Warning
detects the vehicle departing the lane.
The steering wheel will not be controlled.

Information
If the steering wheel is held very lightly
the message may still appear because Lane
Keeping Assist may not recognize that the
driver has their hands on the wheel.
WARNING
The warning message may appear
late according to road conditions.
Therefore, always have your hands on
the steering wheel while driving.

Driver’s hands not detected.
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”, Lane Keeping Assist 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, Lane Keeping
Assist will start controlling the steering
wheel.
WARNING
• Lane Keeping Assist is a supplemental
function only. It is the responsibility of
the driver to safely steer the vehicle
and to maintain it in its lane.
• Turn off Lane Keeping Assist 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
Lane Keeping Assist, the driver can still
steer to control the steering wheel.
The steering wheel may feel heavier when
the steering wheel is assisted by Lane
Keeping Assist than when it is not.
