LKA Operation
ODN8069059
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.
- Whit

e: Sensor does not detect lane
markers or vehicle speed is under 40
mph (64 km/h).
- Gr

een: 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 →
Driv

er Assistance → Lane Safety → Lane
K

eeping 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
lane in front of you, LKA system
operates as follows:
•„Left lane departure warning•„Right lane departure warning

1. A visual w arning 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 s
ystem will help control the
vehicle’s steering to prevent the
vehicle from crossing the lane maker
in below conditions.
- V
ehicle speed is over 40 mph (64
km/h)
- The s
ystem detects both lane
markers
- When driving, the v
ehicle is located
between both lanes normally.
- The s
teering 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
steering 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.
OOSH069085L
Driver’s hands not detected.
LKA system is disabled temporarily
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 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 w

eather
-In bad r

oad conditions
-When the s

teering 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.

Limitations of the System
LKA system may operate prematurely
even if the vehicle does not depart from
the intended lane, OR, LKA system may
not assist your steering or warn you if the
vehicle leaves the intended lane under
the following circumstances:
When the lane and road conditions are
poor
• It is difficult to distinguish the lane
marking from the road surface or the
lane marking is faded or not clearly
marked.
• It is difficult to distinguish the color of
the lane marker from the road.
• There are markings on the road
surface that look like a lane marker
that is inadvertently being detected
by the camera.
• The lane marker is indistinct or
damaged.
• The lane marker is merged or divided
(e.g. tollgate).
• The lane number increases or
decreases or the lane marker are
crossing complicatedly.
• There are more than two lane markers
on the road in front of you. •
The lane marker is very thick or thin.
• The lane is very wide or narrow.
• The lane ahead is not visible due
to rain, snow, water on the road,
damaged or stained road surface, or
other factors.
• The shadow is on the lane marker by
a median strip, trees, guardrail, noise
barriers, etc.
• The lane markers are complicated or a
structure substitutes for the lines such
as a construction area.
• There are crosswalk signs or other
symbols on the road.
• The lane marker in a tunnel is stained
with oil, etc.
• The lane suddenly disappears such as
at the intersection.

6-66
When external condition is intervened
• The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing
under a bridge.
• The brightness outside is too low such
as when the headlamps are not on at
night or the vehicle is going through
a tunnel.
• There is a boundary structure in the
roadway such as a concrete barrier,
guardrail and reflector post that is
inadvertently being detected by the
camera.
• When light coming from a street light
or an oncoming vehicle is reflected on
a wet road surface such as a puddle in
the road.
• The field of view in front is obstructed
by sun glare.
• There is not enough distance between
you and the vehicle in front to be
able to detect the lane marker or the
vehicle ahead is driving on the lane
marke.
• Driving on a steep grade, over a hill, or
when driving on a curved road.
• The adverse road conditions cause
excessive vehicle vibrations while
driving.
• The surrounding of the inside rear
view mirror temperature is high due to
direct sunlight, etc.
• Road surface is not even. When front visibility is poor
•
The windshield or the camera lens is
blocked with dirt or debris.
• The windshield glass is fogged up; a
clear view of the road is obstructed.
• Placing objects on the dashboard, etc.
• The sensor cannot detect the lane
marker because of fog, heavy rain or

System Description
Blind-Spot Collision Warning
Blind-Spot Collision Warning system
uses rear corner radar sensors to monitor
and warn the driver of an approaching
vehicle in the driver’s blind spot area.
(1)
Blind-spo
t vehicle warning
OIK057138
BCW system detects and warns vehicles
in blind-spot.
The blind spot detection range varies
relative to vehicle speed.
Note that if your vehicle is traveling
much faster than the vehicles around
you, the warning will not occur. (2)

F
ast approach vehicle warning
OIK057139L
BCW system will alert you when a vehicle
is detected approaching in an adjacent
lane at a high rate of speed. If the driver
activates the turn signal when the system
detects an oncoming vehicle, the system
sounds an audible alert.
Blind-Spot Collision-Avoidance
Assist
ODN8H059322
Blind-Spot Collision-Avoidance Assist
system detects the front lane through the
front view camera installed on the upper
front windshield and detects the side/
rear areas through rear corner radars.

Blind-Spot Collision-Avoidance Assist
system may activate the Electronic
Stability Control (ESC) in accordance
with a colliding possibility with an
approaching vehicle while changing
lanes. It is to lower the colliding risk or
help mitigate the colliding damage.

• Always be aware of road conditions
while driving and be alert for
unexpected situations even though
the Blind-Spot Collision Warning
system and Blind-Spot Collision-
Avoidance Assist system are
operating.
• Blind-Spot Collision Warning system

and Blind-Spot Collision-Avoidance
Assist system are not substitutes
for proper and safe driving. Always
drive safely and use caution when
changing lanes or backing up the
vehicle.
