Driving your vehicle
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.
✽ ✽NOTICE
• LKA helps prevent the driver
from moving out of the lane unin-
tentionally by assisting the dri-
ver’s steering. However, the sys-
tem is just a convenience function
and the steering wheel is not
always controlled. While driving,
the driver should pay attention to
the steering wheel.
• The operation of the LKA can be cancelled or not work properly
according to road condition and
surroundings. Always be cautious
when driving.
• Do not disassemble a front view camera temporarily for tinted
window or attaching any types of
coatings and accessories.
If you disassemble the camera and
assemble it again, take your vehi-
cle to an authorized Kia dealer
and have the system checked to
need a calibration. (Continued)
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 steer the steering wheel suddenly when the
steering wheel is being assist-
ed 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.

(Continued)
• When you replace the windshield
glass, front view camera or related
parts of the steering, take your
vehicle to an authorized Kia deal-
er and have the system checked to
need a calibration.
• The system detects lane markers and controls the steering wheel by
a front view camera, therefore, if
the lane markers are hard to
detect, the system may not work
properly. 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 crash pad that reflects light such as mir-
rors, white paper, etc. it may cause
malfunction of LKA if the sunlight
is reflected. (Continued)(Continued)
• You may not hear warning sound
of LKA because of the excessive
audio sound.
• If you continue to drive with your hands off the steering wheel, the
LKA will stop controlling the
steering wheel after the hands off
alarm. After then, if you drive
with your hands on the steering
wheel, the control will be activated
again.
• If the vehicle speed is high, steer- ing 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 steer- ing wheel, the system may not
assist steering.
• If you attach objects to the steer- ing wheel, hands off alarm may
not work properly.LKA operation
To activate/deactivate the LKA:
With the ignition switch in the ON
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
will initially illuminate white.
When the indicator(white) activated
in the previous ignition cycle, the
system turns on without any control.
If you press the LKA button again,
the indicator on the cluster display
will go off.

Driving your vehicle
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 40 mph
(64 km/h).
- 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 40 mph (64 km/h)
and all the activation conditions are
satisfied, a green steering wheel
indicator will illuminate and the
steering wheel will be controlled.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.

If the speed of the vehicle is over 40
mph (64 km/h) 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 40 mph (64
km/h).
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
is not satisfied, the system will con-
vert to LDW and warn the driver
only when the driver crosses the
lane markers. In this scenario, the
LDW system does not provide any
steering inputs into the vehicle for
you. Accordingly, you must take the
necessary steps to maintain con-
trol of the vehicle and keep it with-
in the lanes.

Driving your vehicle
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 controlling the steering
wheel.
WARNING
Always have your hands on the
steering wheel while driving.
If you hold the steering wheel lightly, the system would gen-
erate hands off warning
because LKA can treat the sit-
uation as you do not grab the
wheel.

WARNING
The driver is responsible foraccurate steering.
Even though the steering is assisted by the system, the
driver may control the steer-
ing wheel.
Turn off the system and drive the vehicle in below situa-
tions.
- In bad weather
- In bad road condition
- 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-

The steering will not be assisted when the lane is very wide or nar-
row.
The steering will not be assisted when only one side lane marker is
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.
