Driving your vehicle
The Lane Keeping Assist System
helps detect lane markers on the
road with a camera at the front wind-
shield, and assists the driver's steer-
ing to help keep the vehicle 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 slight counter-
steering torque, trying to prevent the
vehicle from moving out of its lane.
LANE KEEPING ASSIST SYSTEM (LKAS) (IF EQUIPPED)
OAE056048
The Lane Keeping Assist
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 System (LKAS):
•Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
•LKAS helps to prevent the
driver from moving out of the
lane unintentionally by assist-
ing 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.
(Continued)
WARNING
(Continued)
•The operation of the LKAS
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
•Do not disassemble the LKAS
camera temporarily to tint the
window or attach any types of
coatings and accessories. If
you disassemble the camera
and assemble it again, we rec-
ommend that you take your
vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.
•When you replace the wind-
shield glass, LKAS camera or
related parts of the steering
wheel, we recommend that
you take your vehicle to an
authorized HYUNDAI dealer
and have the system checked
for calibration.

LKAS operation
To activate/deactivate the LKAS:
With the ignition switch in the ON
position, press the LKAS button
located on the instrument panel on
the left hand side of the steering
wheel. (Continued)
•The system detects lane mark-
ers and controls the steering
wheel by a camera, therefore,
if the lane markers 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 LKAS.
•You may not hear a warning
sound of LKAS because of
excessive audio 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.
(Continued)
(Continued)
•Always have your hands on
the steering wheel while the
LKAS system is activated. If
you continue to drive with
your hands off the steering
wheel after the "Keep hands
on steering wheel" warning
message appears, the system
will stop controlling the steer-
ing wheel.
•The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
rate when leaving a lane the
vehicle may not 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 trailer, make
sure that you turn off the
LKAS system.

The indicator in the cluster display
will initially illuminate white. This indi-
cates the LKAS is in the READY but
NOT ENABLED state.
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 LKAS
button again, the indicator on the
cluster goes off.
The color of indicator will
change depending on the
condition of LKAS.
- White : Sensor does not detect lane
markers or vehicle speed is
under 60 km/h (40 mph).
- Green : Sensor detects lane mark-
ers and the system is able
to control vehicle steering.
LKAS activation
• To see the LKAS screen on the
LCD display in the cluster, select
SCC/LKAS mode ( ) for cluster
type A or ASSIST mode ( ) for
cluster type B. For more informa-
tion, refer to "LCD Display Modes"
in chapter 3.
• When both lane markers are
detected and all the conditions to
activate the LKAS are satisfied, a
green steering wheel indicator will
illuminate and the LKAS indicator
light will change from white to
green. This indicates that the LKAS
system is in the ENABLED state
and the steering wheel will be able
to be controlled.

• If vehicle speed is over 60 km/h (40
mph) and the system detects lane
markers, the color changes from
gray to white.
• If the system detects the left lane
marker, the left lane marker color
will change from gray to white.• If the system detects the right lane
marker, the right lane marker color
will change from gray to white.
• Both lane markers must be detect-
ed for the system to fully activate.• If your vehicle speed exceeds 60
km/h (40 mph) and the LKAS but-
ton is ON, the system is enabled. If
your vehicle departs from the pro-
jected lane in front of you, the
LKAS operates as follows:
A visual warning appears on the
cluster LCD display. Either the left
lane marker or the right lane marker
in the cluster LCD display will blink
depending on which direction the
vehicle is veering.
If the steering wheel appears, the
system will control the vehicle’s
steering to prevent the vehicle from
crossing the lane marker.

Keep hands on steering wheel
If the driver takes their hands off the
steering wheel for several seconds
while the LKAS is activated, the sys-
tem will warn the driver.
Information
If the steering wheel is held very light-
ly the message may still appear
because the LKAS system may not
recognize that the driver has their
hands on the wheel.
Driver's grasp not detected.
LKAS will be disabled momentarily
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.
