Lane Following Assist is designed to
center the vehicle in the chosen lane
by using a front view camera on top
of the windshield.
It can only become active in combi-
nation with Smart Cruise Control
and therefore assists the driver in his
task to control the lateral movement
of the vehicle.
* LFA stands for Lane Following
Assist.
LANE FOLLOWING ASSIST (LFA) (IF EQUIPPED)
ODEP059029
WARNING
It is the driver's responsibility
to operate the steering wheel
for safe driving.
Do not turn the steering wheel
hastily if LFA is operating.
LFA assists the steering
wheel control so that the vehi-
cle can stay in the center of
the lane. LFA does not auto-
matically control the steering
wheel at all times, which
means the driver must keep
hands on the wheel at all
times while driving.
When using LFA, always be
aware of surroundings and
road conditions that may
interrupt or stop LFA.
CAUTION
- Do not attach glass tinting,
stickers, accessories to the
windshield where the front
view camera near the indoor
mirror is placed.
- The removal or re-assembly of
the front view camera to
attach tinting, stickers, acces-
sories may require LFA to be
thoroughly inspected and
modified. In such case, have
your vehicle inspected by an
authorized Kia dealer.
- Inspection or modification
may be required when replac-
ing parts related to the wind-
shield or front view camera,
steering. we recommend that
the system be checked by an
authorized Kia dealer.

LFA operation
To use Lane Following Assist two
steps are necessary:
(1) LFA has to be enabled, and
(2) SCC has to be activated
With the ignition switch or ENGINE
START/STOP button in the [ON],
select or release the setting from
“User setting Driver Assistance 
Driving Assist Lane Following
Assist”.
Select LFA in the user setting of the
instrument panel.
LFA status is remembered by the
function and therefore does not need
to be enabled again for each new
journey.
(Continued)
- Depending on your surround-
ings and road conditions, LFA
could fail to recognize the
lane and stop working. In turn,
extra caution is required
while driving with LFA on.
- Be sure to check the non-
operating conditions and cau-
tions for the driver before
using LFA.
- Do not place reflective materi-
als such as white paper or
mirror on the crash pad.
Sunlight reflections can cause
a malfunction in LFA.
- Too big sound from the sound
function can interrupt the
alarming sound from LFA.
(Continued)(Continued)
- Keeping your hands off the
wheel while driving will trigger
the hands-off warning and
deactivate the steering-assist
function. Put your hands back
on the wheel, then the steer-
ing-assist system will be re-
activated.
- When driving at a high speed,
the steering assist force can
become weak and the vehicle
can drive out of its lane. Extra
caution is required, and com-
ply with the speed limit.
- Attaching an object to the
steering wheel could deter
steering assistance.
- Attaching an object to the
steering wheel could deter the
hands-off alarming system.

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.

Driving your vehicle
LFA malfunction
The warning message popped up
(turned off after a certain period of
time)means a problem with LFA. If
this occurs, we recommend that the
system be checked by an authorized
Kia dealer.
CAUTION
Hands-off warnings may be
delayed depending on road
conditions. Always keep your
hands on the steering wheel
while driving.
Hold the steering wheel tight.
Otherwise, LFA could mis-
judge that the driver hands off
the wheel, and a hands-off
warning may occur.
CAUTION
It is the driver’s responsibility
to operate the steering wheel
while driving.
With LFA on, the driver can
steer the vehicle by operating
the wheel on his own.
We recommend that the driver
turns off LFA and operates the
steering wheel by himself in
the following cases
- bad weather
- bad road conditions
- when frequent operation of
the steering wheel is required
- when towing other vehicle or
trailers
The steering wheel can feel
heavy or light if LFA is assist-
ing the steering.

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.
