Lane Following Assist system helps
detect lane markers on the road
with a front view camera at the front
windshield, and assists the driver’s
steering to help keep the vehicle
between lanes.
WARNING
Lane Following Assist system is not a
substitute for safe driving practices,
but a convenience function. 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 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 center 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.
• Do not disassemble LFA 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.
• When you replace the windshield
glass, LFA system camera or related
parts of the steering wheel, have the
vehicle inspected by an authorized
HYUNDAI dealer.
• 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.
• Please refer to “Limitations of the
S y s t e m ”.
• 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 system from functioning
properly.
• 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 message
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.
• 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 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.
LFA Operation
ODN8069079
With the Engine Start/Stop button
is in the ON or START position, Lane
Following Assist can be activated by
pressing the button.
Operating conditions
When the system is activated, the
indicator (
) on the cluster will
illuminate. The color of the indicator will
change depending on the condition of
LFA system.
- Green: Steering assist mode is ON
- White: Steering assist mode is OFF
LFA system operation • If the vehicle is inside the lane with
both lanes detected by the system
(lane color changes from gray to
white), and there is no abrupt steering
made by the driver, LFA system
changes to steering assist mode. The
indicator light will come on
green, and the system helps the
vehicle stay in line by controlling the
steering wheel.
When the steering wheel is not
controlled temporarily, the
indicator light will flash green and
change to white.
