Driving your vehicle
Lane Following Assist system is
designed to center the vehicle in the
chosen lane by using a front mount-
ed 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 system assists the steer-
ing wheel control so that the
vehicle can stay in the center
of the lane. LFA system does
not automatically 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 system,
always be aware of surround-
ings and road conditions that
may interrupt or stop LFA sys-
tem.
CAUTION
- Do not attach glass tinting,
stickers, accessories to the
windshield where the front
camera near the indoor mirror
is placed.
- The removal or re-assembly of
the front camera to attach tint-
ing, stickers, accessories may
require LFA system to be thor-
oughly inspected and modi-
fied. 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 camera, steer-
ing. we recommend that the
system be checked by an
authorized Kia dealer.

LFA system operation
To use Lane Following Assist two
steps are necessary:
(1) LFA system has to be enabled,
and
(2) SCC system 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 system in the user setting
of the instrument panel.
The LFA system status is remem-
bered by the system and therefore
does not need to be enabled again
for each new journey.
(Continued)
- Depending on your surround-
ings and road conditions, LFA
system could fail to recognize
the lane and stop working. In
turn, extra caution is required
while driving with LFA system
on.
- Be sure to check the non-
operating conditions and cau-
tions for the driver before
using LFA system.
- Do not place reflective materi-
als such as white paper or
mirror on the crash pad.
Sunlight reflections can cause
a malfunction in LFA system.
- Too big sound from the sound
system can interrupt the
alarming sound from LFA sys-
tem.
(Continued)(Continued)
- Keeping your hands off the
wheel while driving will trigger
the hands-off warning and
deactivate the steering-assist
system. 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 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, 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 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 system, the system con-
trols 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 system assist-
ing the steering, the hands-off warn-
ing 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 system released, the
steering assist will re-start.
WARNING
LFA system ensures the vehicle
stays in its lane. LFA system
does not guarantee 100% safe-
ty. Make sure you always check
road conditions and drive safe-
ly at all times.
Never completely rely on your
LFA system.

Driving your vehicle
LFA system malfunction
The warning message popped up
(turned off after a certain period of
time)means a problem with LFA sys-
tem. 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 system could
misjudge 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 system on, the driv-
er can steer the vehicle by
operating the wheel on his
own.
We recommend that the driver
turns off LFA system 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 system is
assisting the steering.

Limitation of the system
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 system 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 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 110 mph (180 km/h), steering
assist mode may not work. When sudden steering is made,
the system could be temporarily
deactivated.
If you change the lane in a hurry,
the system 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 system 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 the LFA system as shown
below, the driver may need to be
careful because it may not operate or
may cause unnecessary operation.

dition
