If you press the LKAS button again,
the indicator on the cluster display
will go off. The color of indicator will change
depend on the condition of LKAS.
- White : Sensor does not detect thelane marker or vehicle speed is less than 64 km/h (40 mph).
- Green : Sensor detects the lane marker and system is able to con-
trol the steering.LKAS activation
To see the LKAS screen on theLCD display in the cluster, Tab to
the ASSIST mode ( ). For more
details, refer to "LCD Display" inchapter 3.
After LKAS is activated, if both lane markers are detected, vehicle
speed is over 64 km/h (40 mph)
and all the activation conditions are
satisfied, a green steering wheelindicator will illuminate and the
steering wheel will be controlled.
OLF057562N The Lane Keeping Assist System is a system to help pre-

If the vehicle moves out its lane
because steering torque for assis-tance is not enough, the line indica-
tor of deviation direction will blink.Keep hands on steering wheel
If the driver takes hands off the steer-
ing wheel for several seconds while
the LKAS is activated, the system
will warn the driver.5

The warning message may
appear late according to road
conditions. Therefore, always
have your hands on the steer-ing wheel while driving.
If you hold the steering wheel
lightly, the system would gen-erate hands off warningbecause LKAS can treat the
situation as you do not grabthe wheel.
WARNING

Driver's grasp not detected.
LKAS will be disabled temporarily
If the driver still does not have their
hands on the steering wheel after
several seconds, the system will not
control the steering wheel and warn
the driver only when the driver cross-
es the lane markers.
However, if the driver has their hands
on the steering wheel again, the sys-
tem will start controlling the steeringwheel.
LKAS malfunction
Check LKAS
LKAS failure indicator
The LKAS failure indicator (yellow) will illuminate if the LKAS is not
working properly. Have your vehicle
checked by an authorized HYUNDAI
dealer.

The driver is responsible for accurate steering.
Turn off the system and drive
the vehicle in below situa-tions. - In bad weather
- In bad road condition
- When the steering wheelneeds to be controlled by the
driver frequently.
The steering wheel may feel
heavier when the steering
wheel is assisted by the sys-tem than when it is not.
WARNING

5-59
Driving your vehicle
The system will be cancelled when:
You change lanes with the turn sig-nal.
- Using the turn signal to changelanes.
- If you change lanes without the turn signal on, the steering wheel might be controlled.
LKAS can transit to steering assist mode when the car is near to mid-dle of the lane after system on or
the lane was changed. LKAS can
not assist steering if the vehicle fol-
lows lane marker too close contin-
uously before transition to steering
assist mode.
The control of ESC (Electronic Stability Control) or VSM (Vehicle
Stability Management) is activated.
The steering will not be assisted when your drive fast on a sharp
curve.
The steering will not be assisted when vehicle speed is below 64
km/h (40 mph) and over 177 km/h(110 mph).
The steering will not be assisted when you change lanes fast. The steering will not be assisted
when you brake suddenly.
The steering will not be assisted when the lane is very wide or nar-
row.
The steering will not be assisted when only one side lane marker isdetected.
There are more than two lane markers such as a constructionarea.
Radius of a curve is too small.
When you turn steering wheel sud- denly, the LKAS will be disabled
temporarily.
Driving on a steep slope or hill.

LKAS function change Lane Departure Warning
LDWS alerts the driver with a visual
and acoustic warning when the sys-
tem detects the vehicle leaving the
lane. In this mode, the steering wheel
will not be controlled. When the vehi-
cle’s front wheel contacts the inside
edge of lane line, LKAS issues the
lane departure warning.
Standard LKA
The Standard LKA mode guides the
driver to help keep the vehicle within
the lanes. It rarely controls the steer-
ing 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.
Active LKA
The active LKA mode provides more
frequent steering wheel control in
comparison with the Standard LKA
mode. Active LKA can reduce the dri-
ver’s fatigue to assist the steering for
maintaining the vehicle in the middle
of the lane.
Driving your vehicle
The driver can change LKAS to Lane Departure Warning System (LDWS) or
the LKAS mode between Standard LKA and Active LKA from the User
Settings Mode on the LCD display.

marker is covered with dust.
It is difficult to distinguish the color of the lane marker from road.
There is something looks like a lane marker.
The lane marker is indistinct or damaged.
The number of lanes increases/ decreases or the lane lines are
crossing (Driving through a toll
plaza/toll gate, merged/dividedlane).
There are more than two lane markers.
The lane marker is very thick or thin.
The lane marker is not visible due to snow, rain, stain, a puddle or
other factors. A shadow is on the lane marker
because of a median strip,
guardrail, noise barriers and oth-
ers.
When the lane markers are compli- cated or a structure substitutes for
the lines such as a constructionarea.
There are crosswalk signs or other symbols on the road.
The lane marker in a tunnel is cov- ered with dirt or oil.
The brightness of outside changes suddenly when entering or exitinga tunnel.
The headlamps are not on at night or in a tunnel, or light level is low.
There is a boundary structure in the roadway.
The light of street, sun, oncoming vehicle and so on reflects from the
water on the road.
When light shines brightly in the reverse direction you drive.
The lane suddenly disappears such as at the intersection. The distance from the vehicle
ahead is very short or the vehicle
ahead drives hiding the lane line.
You drive on a steep grade or a sharp curve.
The vehicle vibrates heavily.
The temperature near inside mirror is very high due to direct sun light.
The lens or windshield is covered by strange materials.
The sensor cannot detect the lane because of fog, heavy rain or snow.
The windshield is fogged by humid air in the vehicle.
