(Continued)
Do not damage the sensor or
sensor area by a strong
impact. If the sensor moves
slightly off position, Smart
Cruise Control will not operate
correctly without any warning

If this occurs, have your vehi-
cle checked by an authorized
Kia dealer as soon as possi-
ble.

paint anything on the sensor
cover.
If the front bumper becomes
damaged in the area around
the radar sensor, Smart Cruise

Do not tint the window or
install stickers, accessories
around the inside mirror
where the camera is installed.
Make sure the frontal camera
installation point does not get
wet.

LFA activation
If the vehicle is inside the lane with
both lanes recognized by the func-
tion, and there is no steep steering
made by the driver, LFA changes into
steering assist mode. The indicator
light will come on green, and the
function helps the vehicle stay in line
by controlling the steering wheel.
When the steering wheel is not con-
trolled temporarily, the indicator light
will flash green and changes to
white.
When the both lanes are not recog-
nized by the function, the function
controls the steering wheel limitedly
whether there is a vehicle in front or
not.
Warning
If you keep your hands off the wheel
while driving with LFA assisting the
steering, the hands-off warning will
be triggered.
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 LFA released, the steer-
ing assist will re-start.
WARNING
LFA ensures the vehicle stays
in its lane. LFA does not guar-
antee 100% safety. Make sure
you always check road condi-
tions and drive safely at all
times.
Never completely rely on your
LFA.

Limitation of the function
If the driver turns on the turn signal
light or the emergency warning
light to change the lane
- Operate the turn signal light
switch before changing the lane
- If you change the lane without
operating the turn signal lights,
steering reaction force of the
wheel may occur.
Once LFA is turned on or the lane
is changed, the vehicle should be
in the center of the road to switch
to the steering assist mode. If the
driver keeps driving along the lane,
LFA will not assist the steering.
When the ESC or VSM is activat-
ed, the function 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 110 mph (180 km/h), steering
assist mode may not work. When sudden steering is made,
the function could be temporarily
deactivated.
If you change the lane in a hurry,
the function does not assist the
steering.
If the vehicle suddenly stops, it
does not assist the steering.
If the lane is too narrow or too
wide, steering is not assisted.
If the function is not able to recog-
nize a vehicle in front and either of
the lanes is not recognized, the
steering is not assisted
If the radius is too small for the
curve
Cautions for the driver
If the lane recognition is difficult or
limited for LFA as shown below, the
driver may need to be careful
because it may not operate or may
cause unnecessary operation.
• Roads or lane markings in bad con-
dition
- When The lane is tainted or invisible
- When the driver cannot see the
lane due to rain, snow, dust,
sand, oil, puddles, etc
- When roads are set or the colors
of the lane and road are not dis-
tinctive
- If there is a sign other than the
lane near the lane or a mark sim-
ilar to the lane
- When the lane is not clear or
damaged
- If the road is covered in the shad-
ows of objects around the road,
such as medians, guard rails,
noise walls, and trees
