OAEE056144R
(Continued)
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 system".
Do not remove or damage the
related parts of LKA system.
You may not hear a warning
sound of LKA system
because of excessive audio
sound.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
(Continued)
(Continued)
Always have your hands on
the steering wheel whilst the
LKA system is activated. If
you continue to drive with
your hands off the steering
wheel after the "Keep hands
on steering wheel" warning
message appears, the system
will stop controlling the steer-
ing 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.
Whilst other beeps such as
the seat belt warning sound
are in operation and override
the LKA alarming system,
LKA beeps may not occur

Driving your vehicle
The indicator in the cluster display
will initially illuminate white. This indi-
cates the LKA system is in the
READY but NOT ENABLED state. The colour of indicator
will change depending on
the condition of LKA sys-
tem.
- White : Sensor does not detect
lane markers or vehicle
speed is under 37 mph (60
km/h).
- Green : Sensor detects lane mark- ers and the system is able
to control vehicle steering.
LKA activation
To see the LKA screen on the LCDdisplay in the cluster, select
ASSIST mode ( ). For more
information, refer to "LCD Display
Modes" in chapter 3.
When both lane markers are detected and all the conditions to
activate the LKA system are satis-
fied, a green steering wheel indica-
tor will illuminate and the LKA sys-
tem indicator light will change from
white to green. This indicates that
the LKA system is in the
ENABLED state and the steering
wheel will be able to be controlled.
OAE058247R
The Lane Keeping Assist (LKA)
system is a system to prevent
the driver from leaving the lane.
However, the driver should not
solely rely on the system but
always check the road condi-
tions when driving.
WARNING

Driving your vehicle
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", the system will not control
the steering wheel and warn the driv-
er only when the driver crosses the
lane markers.
However, if the driver has their hands
on the steering wheel again, the sys-
tem will start controlling the steering
wheel.Information
• Even though the steering is assistedby 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.
i
The driver is responsible for
accurate steering.
Turn off the system and drive
the vehicle in below situa-
tions.
- In bad weather
- In bad road condition
- When the steering wheelneeds to be controlled by the
driver frequently.
WARNING
OAE058252L

Warning light and message
Check LKA (Lane Keep Assist)system
If there is a problem with the system
a message will appear for a few sec-
onds. If the problem continues the
LKA system failure indicator will illu-
minate.
LKA system failure indicator
The LKA system failure
indicator (yellow) will illu-
minate if the LKA system
is not working properly.
We recommend that the system be
checked by a HYUNDAI authorised
repairer.
When there is a problem with the
system do one of the following:
Turn the system on after turning the vehicle 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, we rec-
ommend that the system be checked
by a HYUNDAI authorised repairer.
The LKA system will not be in the
ENABLED state and the steering
wheel will not be assisted when:
Vehicle speed is below 37 mph (60 km/h) and over 112 mph (180
km/h).
Only one lane marker is detected.
The turn signal is turned on before changing a lane. If you change
lanes without the turn signal on,
the steering wheel might be con-
trolled.
The hazard warning flasher is on.
The width of the lane is below 2.6m (8.5 feet) or over 4.5m (15 feet).
ESC (Electronic Stability Control) or VSM (Vehicle Stability Management)
is activated.
The vehicle is driven on a sharp curve.
The vehicle brakes suddenly.
The vehicle makes sharp lane changes.
There are more than two lane markers on the road. (e.g. construc-
tion area)

Driving your vehicle
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 assist your
steering or 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 lanemarking from the road surface or
the lane marking is faded or not
clearly marked.
It is difficult to distinguish the colour 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 merged or
divided. (e.g. tollgate)
The lane number increases or decreases or the lane marker are
crossing complicatedly.
There are more than two lane markers on the road in front of you.
The lane marker is very thick or thin.
The lanes ahead are not visible due to rain, snow, water on the
road, damaged or stained road
surface, or other factors.
The shadow is on the lane marker by a median strip, trees, etc.
The lanes are incomplete or the area is in a construction zone.
There are crosswalk signs or other symbols on the road.
The lane marker in a tunnel is stained with oil, etc.
The lane suddenly disappears such as at the intersection. When external condition is inter-
vened
The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing
under a bridge.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
There is a boundary structure in the roadway such as a concrete
barrier, guardrail and reflector post
that is inadvertently being detected
by the 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.
There is not enough distance between you and the vehicle in
front to be able to detect the lane
marker or the vehicle ahead is driv-
ing on the lane marker.

Driving on a steep grade, over ahill, or when driving on a curved
road.
The adverse road conditions cause excessive vehicle vibrations whilst
driving.
The surrounding of the inside rear view mirror temperature is high
due to direct sunlight, etc.
When front visibility is poor
The windscreen or the LKA cam- era lens is blocked with dirt or
debris.
The windscreen glass is fogged up; a clear view of the road is
obstructed.
Placing objects on the dashboard, etc.
The sensor cannot detect the lane because of fog, heavy rain or snow.LKA system function change
The driver can change LKA to Lane
Departure Warning (LDW) or change
the LKA mode between Standard
LKA and Active LKA from the LCD
display. Go to the 'User Settings →
Driver assistance → Lane safety →
Lane LDW (Lane Departure
Warning)/Standard LKA (Lane Keep
Assist)/Active LKA (Lane Keep
Assist)'.
The system is automatically set to
Standard LKA if a function is not
selected.
LDW (Lane Departure Warning)
LDW alerts the driver with a visual
warning and a warning alarm when
the system detects the vehicle
departing the lane. The steering
wheel will not be controlled.
Standard LKA (Lane Keep Assist)
The Standard LKA mode guides the
driver to help keep the vehicle within
the lanes. It rarely controls the steer-
ing 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.
Active LKA (Lane Keep Assist)
The Active LKA mode provides more
frequent steering wheel control in
comparison with the Standard LKA
mode. Active LKA can reduce the dri-
ver’s fatigue to assist the steering for
maintaining the vehicle in the middle
of the lane.

and accessories.
If you disassemble a camera and
assemble it again, we recom-
mend that you take your vehicle
to a HYUNDAI authorised repair-
er and have the system checked
for calibration.

mined (possibly due to wide
variation in tyre pressures,
uneven tyre wear-out, toe-
in/toe-out alignment).
The vehicle drives on a curvy
road.
The vehicle drives through a
windy area.
The vehicle drives on a
bumpy road.
