The Lane Keeping Assist system 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 slight counter-
steering torque, trying to prevent the
vehicle from moving out of its lane.
LANE KEEPING ASSIST (LKA) SYSTEM (IF EQUIPPED)
WARNING
Driver is responsible for being
aware of surroundings and
steering the vehicle for safe
driving practices.
Do not turn the steering wheel suddenly when the steering
wheel is being assisted by the
system.
WARNING
The Lane Keeping Assist System
is a supplemental system and is
not a substitute for safe driving
practices. It is the responsibility
of the driver to always pay atten-
tion and drive safely.
OJFHP058305L
WARNING
The operation of the LKA canbe cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
Do not disassemble the front view camera temporarily for
tinting window or attaching
any types of coatings and
accessories.
If you disassemble the camera
and assemble it again, take
your vehicle to an authorized
Kia dealer and have the system
checked to need a calibration.
When you replace the wind- shield glass, front view camera
or parts of the steering, take

position, press the LKA button locat-
ed on the instrument panel on the
lower left hand side of the driver.
The indicator in the cluster display

OJFHP058308
(Continued)
The system is designed todetect 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 the related parts of LKA.
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 if the audio vol-
ume is high.
(Continued)(Continued)
If you to drive with your handsoff the steering wheel, the
LKA will stop controlling the
steering wheel after the hands
off alarm. If you drive with
your hands on the steering
wheel again the control will be
activated again.
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.
If you attach objects to the steering wheel, the system
may not assist steering.
If you attach objects to the steering wheel, hands off
alarm may not work properly.

The color of indicator will change
depend on the condition of LKA.
- White : Sensor does not detect the lane marker or vehicle
speed is less than 60
km/h (37 mph).
- Green : Sensor detects the lane
marker and system is able
to control the steering.LKA activation
To see the LKA screen on the LCD
display in the cluster, Tab to the
ASSIST mode ( ).
For further details, refer to ‘menu settings’ in chapter 4.
After LKA is activated, if both lane markers are detected, vehicle
speed is over 60 km/h (37 mph)
and all the activation conditions are
satisfied, a green steering wheel
indicator will illuminate and the
system will provide steering inputs.WARNING
The Lane Keeping Assist system
is a system to help prevent the
driver from leaving the lane.
However, the driver should not
solely rely on the system but
always check the road condi-
tions when driving.

5119
Driving your vehicle
If the speed of the vehicle is over 60
km/h (37 mph) and the system
detects lane markers, the color
changes from gray to white
When the conditions below are met,
LKA will be enable to assist steering.
Vehicle speed is above 64 km/h(40 mph).
Both lane markers are detected by LKA.
The vehicle is between the lane markers.
If LKA can assist steering, a green
steering wheel indicator will illumi-
nate.
Warning
If the vehicle leaves a lane, the lane
marker you cross will blink on the
LCD display.
If the vehicle moves out its lane
because steering torque for assis-
tance is not enough, the line indica-
tor will blink.
If all the conditions to activate LKA are not satisfied, the system will
convert to the Lane Departure
Warning (LDW) system and warn
the driver only when the driver
crosses the lane markers. If the driver takes hands off the steer-
ing wheel for several seconds while
the LKA is activated, the system will
warn the driver.

If the driver still does not have their
hands on the steering wheel after
several seconds, the system will not
control the steering wheel and warn
the driver only when the driver cross-
es the lane markers.
However, if the driver has their hands
on the steering wheel again, the sys-
tem will start providing steering
inputs.
✽ ✽
NOTICE
• Even though the steering is assist-
ed by the system, the driver may
control the steering.
• The steering wheel may feel heav- ier when the steering wheel is
assisted by the system than when it
is not. WARNING
Always have your hands on the
steering wheel while driving
If you hold the steering wheel with a light grip, the system
may generate a hands off
warning.
WARNING
It is the responsibility of thedriver to safely steer the vehi-
cle and to maintain it in its lane.
Even though the steering is assisted by the system, the
driver may control the steer-
ing wheel.
Turn off the LKA system and drive without using the sys-
tem in the following situa-
tions:
- In bad weather
- In bad road conditions
- When the steering wheelneeds to be controlled by the
driver frequently.
The steering wheel may feel heavier when the steering
wheel is assisted by the sys-
tem than when it is not.

- Using the turn signal to changelanes.
- If you change lanes without the turn signal on, the steering wheel
might be controlled.
LKA can transit to steering assist mode when the car is near to mid-
dle of the lane after system on or
the lane was changed. LKA cannot
assist steering if the vehicle follows
a lane marker too closely.
The control of ESC (Electronic Stability Control) or VSM (Vehicle
Stability Management) is activated.
The steering will not be assisted when you drive fast on a sharp
curve. The steering will not be assisted
when vehicle speed is below 60
km/h (37 mph) and over 177 km/h
(110 mph). Always obey all traffic
laws and drive safely.
The steering will not be assisted when you change lanes quickly.

detected.
There are more than two lane markers such as a construction
area.
Radius of a curve is too small.
When you turn steering wheel sud- denly, the LKA will be disabled
temporarily.
Driving on a steep slope or hill.DRIVER’S ATTENTION
The driver must be cautious in the
following situations because the sys-
tem may be limited when recogni-
tion of the lane marker is poor or
limited :
  When lane and road condition is
poor
• It is difficult to distinguish the lane marker from road when the lane
