The Lane Following Assist (LFA)
system is not a substitute for safe
driving practices, but a conven-
ience function. It is the responsi-
bility of the driver to always be
aware of the surrounding and
steer the vehicle.
WARNING
Take the following precautions
when using the Lane Following
Assist (LFA) system:
Do not steer the steering
wheel unnecessarily when the
steering wheel is being assist-
ed 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.
WARNING
The operation of the LFA sys-
tem can be canceled or not
work properly according to
road condition and surround-
ings. Always be cautious
when driving.
Do not disassemble the LFA
system 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, LFA system 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.

LFA operation
The driver can turn on the LFA sys-
tem with the vehicle on and by
selecting "Vehicle settings →Driver
assistance →Driving assist → LFA
(Lane Following Assist)" in the AVN
screen.
The set-up of the LFA system will be
maintained, as selected, when the
vehicle is restarted.
Driving your vehicle
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 LFA system.
You may not hear a warning
sound of LFA 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.
Always have your hands on
the steering wheel while the
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
be turned off automatically.
However, if the driver has their
hands on the steering wheel
again, the system will start
controlling the steering wheel.
The steering wheel may not
be continuously controlled by
the system if the vehicle
speed is too high. 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 nor-
mally or the hands off alarm
may not work properly.
When you tow a trailer, make
sure that you turn off the LFA
system.

Operating conditions
The system is activated when the
Lane Following Assist is selected
from the vehicle Settings mode when
the following conditions are satisfied:
- The Smart Cruise Control is in acti-vation (vehicle deceleration and
acceleration)
- Vehicle speed is lower than 90 mph (145 km/h)
When the system is activated, the
indicator ( ) on the cluster will illu-
minate. The color of the indicator will
change depending on the condition
of LFA system.
- Green : The system is in the assist state.
- White : The system is in the ready state.
LFA activation
After LFA is activated, if the vehicleis within the lane and both lane
markers are detected (lane color
changes grey to white) and there is
no abrupt steering by the driver, indicator light will change from
white to green. This indicates that
the LFA system is in the ASSIST
state and the steering wheel will be
able to be controlled. When the system does not recog-
nize the lane or depending on the
vehicle condition in front (presence
of the vehicle, driving status, etc.).
the steering wheel is controlled
restrictively.
When the control of the steering
wheel is stopped temporarily the
activation indicator blinks in green
and then changes to white.5

Warning message
Keep hands on steering wheel
If the driver takes their hands off from
the steering wheel for certain time
while the LFA system is activated,
the system will warn the driver.
Information
If the steering wheel is held very light-
ly the message may still appear
because the LFA system may not rec-
ognize that the driver has their hands
on the wheel.
Driver's grasp not detected.
LFA 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.

Limitations of the system
The LFA system may operate prema-
turely even if the vehicle does not
depart from the intended lane, OR,
the LFA system may not assist your
steering if the vehicle leaves the
intended lane under the following cir-
cumstances:
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 color 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 indistinct or damaged.
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 lane marker ahead is not visi- ble 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, guardrail,
noise barriers, etc.
The lane markers are complicated or a structure substitutes for the
lines such as a construction area.
There are crosswalk signs or other symbols on the road.
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.
