Lane Following Assist system
is not a substitute for safe driv-
ing practices, but a conven-
ience function. It is the respon-
sibility of the driver to always
be aware of the surroundings
and steer the vehicle.
WARNING
Take the following precautions
when using Lane Following
Assist system:
Do not turn the steering wheel
suddenly when the steering
wheel is being assisted by the
system.
LFA system helps the driver
to keep the vehicle in the cen-
ter of the lane 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 LFA system
can be canceled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
(Continued)
WARNING (Continued)
Do not disassemble the front
view 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, front view cam-
era 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.
The system helps detect 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.

LFA operation
System setting
With the ignition switch is in the ON
position, Lane Following Assist can
be activated by selecting 'User set-
tings →Driver assistance →
Driving assist →Lane following
assist' in the cluster LCD display.
Deselect the setting to turn off the
system.
If the vehicle is turned off then on
again, the system maintains the
last setting. (Continued)
Please refer to "Limitations of
the System".
Do not remove or damage the
related parts of LFA system.
You may not hear a warning
sound of LFA 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 LFA sys-
tem from functioning proper-
ly.
Always have your hands on
the steering wheel while LFA
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
turn off automatically.
However, if the driver has their
hands on the steering wheel
again, the system will start
controlling the steering wheel.
(Continued)
(Continued)
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 LFA sys-
tem.

helps the vehicle stay in line by con-
trolling the steering wheel. If the lane
markers are hard to detect, steering
wheel will be able to be controlled
depending on front vehicle and front
vehicle driving conditions. When the
steering wheel is not controlled tem-
porarily, the indicator light will

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 a
hill, or when driving on a curved
road.
The adverse road conditions cause
excessive vehicle vibrations while
driving.
The surrounding of the inside rear
view mirror temperature is high
due to direct sunlight, etc.
