LKA Operation
ODN8069059ODN8069059
To activate/deactivate LKA system:
With the ignition switch in the ON
position, press LKA system button
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 LKA system is in the READY but
NOT ENABLED state.
Note that the vehicle speed
must be at least approximately
40 mph (64 km/h) to ENABLE
LKA system. The indicator in the
cluster display will illuminate
green.
- White: Sensor does not detect lane markers or vehicle speed is under 40
mph (64 km/h).
- Green: Sensor detects lane markers 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 additional control.
If you press the LKA button again, the
indicator on the cluster goes off.
LKA System Function Change
The driver can change LKA to
Lane Departure Warning or Lane
Keeping Assist from the LCD display
or infotainment system display(if
equipped). Go to the ‘User Settings →
Driver Assistance → Lane Safety → Lane
Keeping Assist/Lane Departure Warning/
Off'. The system is automatically set to
Lane Keeping Assist if a function is not
changed.
Lane Keeping Assist
The LKA mode guides the driver to help
keep the vehicle within the lanes. It
rarely controls the steering wheel, when
the vehicle drives well inside the lanes.
However, it starts to control the steering
wheel, when the vehicle is about to
deviate out of the lanes.
Lane Departure Warning
LDW alerts the driver with a visual
warning and a warning alarm when the
system detects the vehicle departing
the lane. The steering wheel will not be
controlled.

• If vehicle speed is over 40 mph (64 km/h) and the system detects lane
markers, the color changes from gray
to white.
• If your vehicle speed exceeds 40 mph (64 km/h) and LKA system button is
ON, the system is enabled. If your
vehicle departs from the projected

1. 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. 2. LKA system will help 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 normally.
- The steering wheel is not turned suddenly.
When lanes are detected and all the
conditions to activate LKA system are
satisfied, LKA system indicator light
(
) will change from white to green.
This indicates that LKA system is in the
ENABLED state and the steering wheel
will be controlled.

Keep hands on steering wheel
If the driver takes their hands off the
s
teering wheel for several seconds while
LKA system is activated, the system will
warn the driver.
Information
If the steering wheel is held very lightly
the message may still appear because LKA
system may not recognize that the driver
has their hands on the wheel.
WARNING
The warning message may appear
late according to road conditions.
Therefore, always have your hands on
the steering wheel while driving.
OOSH069085LOOSH069085L
Driver’s hands not detected.
LKA system is disabled temporarily
If the driver still does not have their
hands on the s
teering wheel after the
message “Keep hands on steering
wheel”, the system will not control the
steering wheel and warn the driver
only when the driver crosses the lane
markers.
However, if the driver has their hands on
the steering wheel again, the system will
start controlling the steering wheel.
WARNING
• LKA system is a supplemental system
only. It is the responsibility of the
driver to safely steer the vehicle and
to maintain it in its lane.
• Turn off LKA system and drive
without using the system in the
following situations:
- In bad weather
- In bad road conditions
- When the steering wheel needs
to be controlled by the driver
frequently
Information
Even though the steering is assisted by the
system, the driver can still steer to control
the steering wheel.
The steering wheel may feel heavier when
the steering wheel is assisted by the system
than when it is not.

WARNING
• The warning light on the side view
mirror will illuminate whenever a
vehicle is detected at the rear side by
the system.
To avoid accidents, do not focus only
on the warning light and neglect to
see the surrounding of the vehicle.
• Drive safely even though the
vehicle is equipped with Blind-Spot
Collision-Avoidance Assist system.
Do not solely rely on the system
but check your surrounding before
changing lanes or backing the
vehicle up.
• The system may not alert the driver
in some conditions so always check
your surroundings while driving.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning
alarm.
• Playing the vehicle audio system at
high volume may offset the Blind-
Spot Collision Warning system
warning sounds.
• The warning of Blind-Spot Collision-
Avoidance Assist system may not
sound while other system’s warning
sounds.
Blind-Spot Collision-Avoidance
Assist
Blind-Spot Collision-Avoidance Assist
system may apply braking power, when
an approaching vehicle is detected
within a certain distance next to or
behind your vehicle.
It gently applies braking power on the
tire, which is located in the opposite
side of the possibly-colliding point. The
instrument cluster will inform the driver
of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated
when:
- The vehicle drives a certain distance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in the
middle of the vehicle lanes to keep the
system in the ready status.
When the vehicle drives too close to one
side of the vehicle lanes, the system may
not properly operate.
In addition, the system may not properly
control your vehicle in accordance with
driving situations. Thus, always pay close
attention to road situations.

WARNING
• The driver is responsible for accurate
steering.
• Do not unnecessarily operate the
steering wheel, when Blind-Spot
Collision-Avoidance Assist system is
in operation.
• Always pay extreme caution while
driving. The Blind-Spot Collision-
Avoidance Assist system may not
operate or unnecessarily operate
in accordance with your driving
situations.
• Blind-Spot Collision-Avoidance
Assist system is not a substitute
for safe driving practices, but a
convenience function only. It is
the responsibility of the driver to
always drive cautiously to prevent
unexpected and sudden situations
from occurring. Pay attention to the
road conditions at all times.
