• 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.
