• 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
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

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.
