The Lane Keeping Assist (LKA) sys-
tem helps detect lane markers on the
road with a front view camera at the
front windshield, and assists the dri-
ver's steering to help keep the vehi-
cle between 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 counter-steer-
ing torque, to try to prevent the vehi-
cle from moving out of its lane.

The Lane Keeping Assist (LKA)
system is not a substitute for
safe driving practices, but a
convenience function only. It is
the responsibility of the driver
to always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist (LKA) system:
•Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKA system helps to prevent
the driver from moving out of
the lane unintentionally by
assisting the driver's steering.
However, the driver should not
solely rely on the system but
always pay attention on the
steering wheel to stay in the
lane.
WARNING
The operation of the LKA sys-
tem can be canceled or not
work properly according to
road condition and surround-
ings. Always be cautious
when driving.
Do not disassemble the LKA
system camera temporarily to
tint the window or attach any
types of coatings and acces-
sories. If you disassemble the
camera and assemble it again,
take your vehicle to an author-
ized HYUNDAI dealer and
have the system checked for
calibration.
When you replace the wind-
shield glass, LKA system
camera or related parts of the
steering wheel, take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked for calibration.
The system detects lane lines
and controls the steering
wheel by a camera, therefore,
if the lane lines are hard to
detect, the system may not
work properly.

LKA System Operation
To activate/deactivate the LKA sys-
tem:
With the ignition switch in the ON
position, press the LKA system
switch located on the instrument
panel on the left hand side of the
steering wheel. The indicator in the
cluster display will initially illuminate
white. This indicates the LKA system
is in the READY but NOT ENABLED
state.
If you press the LKA button again,
the indicator on the switch and clus-
ter display will go off.
However, if the driver has their
hands on the steering wheel
again, the system will start con-
trolling the steering wheel.
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
speed when leaving a lane the
vehicle may not be able to be
controlled by the system. The
driver must always follow the
speed limit when using the
system.
If you attach objects to the
steering wheel, the system
may not assist steering or the
hands off alarm may not work
properly. When you tow a trail-
er, make sure that you turn off
the LKA system.
When you tow a trailer, make
sure that you turn off the LKA
system.
Please refer to "Limitations of
the system".
Do not remove or damage the
related parts of LKA system.
You may not hear a warning
sound of LKA system because
of excessive audio sound.
If any other warning sound
such as seat belt warning
chime is already generated,
the Lane Keeping Assist
(LKA) system warning may
not sound.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
Always have your hands on the
steering wheel while the LKA
system is activated. Also, when
Active LKA is selected from the
User Settings mode and if you
continue to drive with your
hands off the steering wheel
after the "Keep hands on steer-
ing wheel" warning message
appears, the system will stop
controlling the steering wheel.

Note that the vehicle
speed must be at least
approximately 40 mph
(64 km/h) to ENABLE the
LKA system. The indicator in the
cluster display will illuminate green.
The color of indicator will change
depending on the condition of LKA
system.
- White : Sensor does not detect
lane markers or vehicle
speed is under 40 mph (64
km/h).
- Green : Sensor detects lane mark- ers and the system is able
to control vehicle steering.
Information
If the indicator (white) is activated
from the previous ignition cycle, the
system will turn ON without any addi-
tional control. If you press the LKA
switch again, the indicator on the clus-
ter goes off.
LKA system activation
To see the LKA system screen onthe LCD display in the cluster,
select Assist mode ( ). For more
details, refer to "LCD Display
Modes" in chapter 3.

The Lane Keeping Assist (LKA)
system is a system to help pre-
vent the driver from leaving the
lane. However, the driver should
not solely rely on the system
but always check the road con-
ditions when driving.
WARNING

5-96
Driving your vehicle
If vehicle speed is over 40 mph (64 km/h) and the system detects lane
markers, the color changes from
gray to white.
Both lane markers must be detect- ed for the system to fully activate. If your vehicle departs from the
projected lane in front of you, the
LKA system operates as follows:
1. A visual warning appears on the cluster LCD display. Either the left
lane marker or the right lane mark-
er in the cluster LCD display will
blink depending on which direction
the vehicle is veering. Also, a
warning sound will be heard. 2. The LKA system will control the
vehicle's steering to prevent the
vehicle from crossing the lane
maker in below conditions.
- Vehicle speed is over 40 mph (64 km/h)
- The system detects both lane markers
- When driving, the vehicle is located between both lanes nor-
mally.
- The steering wheel is not turned suddenly.
When lanes are detected and all the
conditions to activate the LKA sys-
tem are satisfied, a LKA system indi-
cator light ( ) will change from
white to green. This indicates that the
LKA system is in the ENABLED state
and the steering wheel will be able to
be controlled.

Warning Light and Message
Keep hands on steering wheel
If the driver takes their hands off the
steering wheel for several seconds
while the LKA system is activated,
the system will warn the driver.
Information
If the steering wheel is held very light-
ly, the message may still appear
because the LKA system may not rec-
ognize that the driver has their hands
on the wheel.
Driver's grasp not detected.LKA system will be disabledtemporarily
If the driver still does not have their
hands on the steering wheel after the
message "Keep hands on steering
wheel", the system will not control
the steering wheel and warn the driv-
er only when the driver crosses the
lane markers.
However, if the driver has their hands
on the steering wheel again, the sys-
tem will start controlling the steering
wheel.
This warning message is available
when Active LKA is selected from the
User Settings mode.
i
The warning message may
appear late according to road
conditions. Therefore, always
have your hands on the steering
wheel while driving.
