LANE KEEPING ASSIST (LKA) SYSTEM (IF EQUIPPED)

• 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

vehicle to an authorized

HYUNDAI dealer and have the

system checked for calibra-

tion.

WARNING

The Lane Keeping Assist (LKA)

system is not a substitute for

safe driving practices. It is the

responsibility of the driver to

always be aware of the sur-

rounding and steer the vehicle.

WARNING

OTLE058182

The Lane Keeping Assist (LKA) sys-

tem detects lane markers on the

road using a forward facing front

camera located on the top center of

the windshield. The LKA system

assists the driver's steering to help

keep the vehicle between the lane

markers.

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.

5

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.

Driving your vehicle

• 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.

Please refer to "Limitations of

the system".

• Do not remove or damage the

related parts of LKA system.

• 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 steer-

ing wheel after the "Keep

hands on steering wheel"

warning message appears,

the system will stop control-

ling the steering wheel.

However, if the driver has their

hands on the steering wheel

again, the system will start

• 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.

such as mirrors, white paper,

etc. The system may malfunc-

tion if the sunlight is reflected.

• 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.
