acceleration control)
Refer to
details.
- Driving the vehicle at 95 mph (150 km/h) and under
Once the system starts working, the
indicator light ( ) comes on the
instrument panel.
The indicator light colors according
to the system status are as follows.
- White: steering assist mode deacti- vation
- Green: steering assist mode activa- tion
(Continued)
- Depending on your surround- ings and road conditions, theLFA system could fail to rec-ognize the lane and stop work-ing. In turn, extra caution isrequired while driving withthe LFA system on.
- Be sure to check the non- operating conditions and cau-tions for the driver beforeusing the LFA system.
- Do not place reflective materi- als such as white paper ormirror on the dashboard pad.Sunlight reflections can causethe LFA system to not operateproperly.
- Loud audio volumes can pre- vent the occupants from hear-ing the alarm sounds from theLFA system
(Continued)(Continued)- Keeping your hands off the wheel while driving will triggerthe hands-off warning anddeactivate the steering-assistsystem. Put your hands backon the wheel, then the steer-ing-assist system will be re-activated.
- When driving at a high speed, the steering assist force canbecome weak and the vehiclecan drive out of its lane. Extracaution is required, and com-ply with the speed limit.
- Attaching an object to the steering wheel could detersteering assistance.
- Attaching an object to the steering wheel could deter thehands-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, 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.

LFA system malfunction
The warning message popped up
(turned off after a certain period of
time)means a problem with the LFA
system.
Have the system checked by an
authorized K900 Kia dealer.
CAUTION
Hands-off warnings may be
delayed depending on roadconditions. Always keep yourhands on the steering wheelwhile driving.
Hold the steering wheel tight. Otherwise, the LFA systemcould misjudge that the driverhands are off the wheel, and ahands-off warning may occur.
CAUTION
It is the driver’s responsibility to operate the steering wheelwhile driving.
With the LFA system on, The driver can steer the vehicle byoperating the wheel on hisown.
We recommend that the driver turns off the LFA system andoperates the steering wheelby himself in the following sit-uations:
- 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 the LFA sys-tem is assisting the steering.

Limitation of the system
If the driver turns on the turn signallight 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 the 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, 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
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 either of the lanes is not recog- nized, 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.
• 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

- If the number of lanes increases
or decreases, or if the lanes inter-
sect with each other more
intensely (tollgate entry section,
road section / joining section,
etc.)
- When there are two or more lane markings such as a construction
section, a designated lane, etc.
- When the lane is crowded such as the construction section or the
lane is replaced by some struc-
tures
- If there is a road marking such as a zigzag lane, crosswalk mark, or
road surface milestone
- When a lane suddenly becomes invisible or disappears from an
intersection
• The external environment affecting the system
- If the outside brightness of the vehi- cle suddenly changes, such as
when entering or exiting the tunnel
or passing under the bridge - If the vehicle's headlights are not
used at night or in the tunnel, or the
brightness of the headlights is too
weak
- If there are boundary structures such as tollgate booths and side-
walk blocks
- If it is difficult to distinguish lanes due to the reflection on the wet road
made by sunlight, streetlight, and
oncoming traffic.
- When the backlight is strongly reflect- ed in the direction of the vehicle
- When Driving to the left or right lane by bus lane or on the bus lane
- If there is not enough distance between the front car or if the lane
is covered by the car ahead of me
- When the lane change is large, such as a steep curve or a continu-
ous curve
- When passing through speed bump, sudden up / down or left /
right slope
- If the vehicle is severely shaken
- When the temperature around the rearview mirror is very high due to
direct sunlight • If the front camera clock is of poor
quality

era or related parts of the
steering, take your vehicle to
an authorized K900 Kia dealer
and have the system checked
to need a calibration.
The system is designed to detect lane markers using a
front view camera. If the lane
markers are hard to detect,
then the system may be limit-
ed. Always be cautious when
using the system.
When the lane markers are hard to detect, please refer to
“Driver’s Attention”.

Do not remove or damage therelated parts of LKA system.
Do not place objects on the dashboard that reflects light
such as mirrors, white paper,
etc. This may prevent the LKA
system from functioning
properly.
You may not hear warning sound of LKA system because
of the excessive audio sound.
When other beeps such as the seat belt warning sound are in
operation and override the
LKA alarming system, LKA
beeps may not occur.
If the vehicle speed is high, steering torque for assistance
will not be enough to keep
your vehicle within the lane. If
so, the vehicle may move out
of its lane. Obey speed limit
when using LKA system.
(Continued)(Continued)
If you attach objects to thesteering wheel, the system
may not assist steering.
