LFA system activation
If the vehicle is inside the lane with
both lanes recognized by the sys-
tem, and there is no steep steering
made by the driver, the LFA system
changes into 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 lane is not recognized, the
steering wheel is controlled in a lim-
ited manner depending on the pres-
ence and the driving condition of the
preceding vehicle.
When the steering wheel is not con-
trolled temporarily, the indicator light
will flash green and changes to white.
Once the LFA system recognizes the
lanes, the color of the lane on the
screen will change from gray to
white.
Warning
If you keep your hands off the wheel
while driving with the LFA system
assisting the steering, the hands-off
warning will be triggered. (The 1
st
warning: warning message, the 2nd
warning: warning message and warn-
ing alarm)
If the driver keeps hands off the
wheel even with the hands-off warn-
ing on, the steering assist is tem-
porarily released automatically.
If you put your hands back on the
wheel with the LFA system released,
the steering assist will re-start.
WARNING
The LFA system ensures the
vehicle stays in its lane. The
LFA system does not guarantee
100% safety. Make sure you
make decisions on the road
after checking the road condi-
tions and safety matters while
driving. Never completely rely
on your LFA system.

should be in the center of the road
to switch to the steering assist
mode. If the driver keeps driving
along the lane, the LFA system will
not assist the steering.
When the ESC or VSM is activat- ed, the system does not assist
steering.
When driving on a curved road at a high speed, steering assist mode
may not work.
When driving at a speed faster than 95 mph (150 km/h), steering

The Lane Keeping Assist (LKA) sys-
tem is designed to detect the 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 in the lanes.When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a counter-steer-
ing torque, trying to prevent the vehi-
cle from moving out of its lane.
