- If you select "Warning Only", theFCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the brake
directly because the FCA system
do not control the brake.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA braking control is auto- matically canceled, when risk fac-
tors disappear.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
After the brake control is acti-
vated, the driver must immedi-
ately depress the brake pedal
and check the surroundings.
The brake activation by the
system lasts for about 2 sec-
onds.
If any other warning sound
such as seat belt warning
chime is already generated,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearing
the system warning sounds.
CAUTION
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions such
as inclement weather and road
conditions may affect the oper-
ation of the FCA system.
WARNING
The FCA braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
Never deliberately drive danger-
ously to activate the system.

Driving your vehicle
The Lane Keeping Assist (LKA) sys-
tem helps detect lane markers on the
road with a front view camera at the
front windshield, and assists the dri-
ver's steering to help keep the vehi-
cle 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 counter-steer-
ing torque, to try to prevent the vehi-
cle from moving out of its lane.

The Lane Keeping Assist (LKA)
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-
roundings and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist (LKA) system:
Do not turn the steering wheel
suddenly when the steering
wheel is being assisted 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.
WARNING
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.

LKA System Operation
To activate/deactivate the LKA sys-
tem:
With the ignition switch in the ON
position, press the LKA system
switch 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 the LKA system
is in the READY but NOT ENABLED
state.
If you press the LKA button again,
the indicator on the switch and clus-
ter display will go off.
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 steering wheel
after the "Keep hands on steer-
ing wheel" warning message
appears, the system will stop
controlling the steering wheel.
However, if the driver has their
hands on the steering wheel
again, the system will start con-
trolling the steering wheel.
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.
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.
The system helps detect lane
markers 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 LKA system.
You may not hear a warning
sound of LKA system if the
audio volume is high.
If any other warning sound
such as seat belt warning
chime is already generated,
the Lane Keeping Assist
(LKA) system warning may
not sound.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. This may prevent the LKA
system from functioning
properly.

Driving your vehicleNote that the vehicle
speed must be at least
approximately 40 mph
(64 km/h) to ENABLE the
LKA system. The indicator in the
cluster will illuminate green.
The color of indicator will change
depending on the condition of LKA
system.
- White : Sensor does not detect
lane markers or vehicle
speed is under 40 mph (64
km/h).
- Green : Sensor detects lane mark- ers 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 addi-
tional control. If you press the LKA
switch again, the indicator on the clus-
ter goes off.
LKA system operation
To see the LKA system screen onthe LCD display in the cluster,

If your vehicle departs from theprojected lane in front of you, the
LKA system operates as follows:
1.A visual warning appears on the cluster LCD display. Either the left
lane marker or the right lane mark-
er in the cluster LCD display will
blink depending on which direction
the vehicle is veering. Also, a warn-
ing sound will be heard. 2.The LKA system will control the
vehicle's steering to prevent the
vehicle from crossing the lane
maker in below conditions.
- Vehicle speed is over 40 mph (64km/h)
- The system detects both lane markers
- When driving, the vehicle is located between both lanes nor-
mally.
- The steering wheel is not turned suddenly.
When lanes are detected and all the
conditions to activate the LKA sys-
tem are satisfied, a LKA system indi-
cator light will change from white to
green. This indicates that the LKA
system is in the ENABLED state and
the steering wheel will be controlled.Warning Light and Message
Keep hands on steering wheel
If the driver takes their hands off the
steering wheel for several seconds
while the LKA system is activated,
the system will warn the driver.
Information
If the steering wheel is held very light-
ly, the message may still appear
because the LKA system may not rec-
ognize that the driver has their hands
on the wheel.

the LKA system may not warn you if
the vehicle leaves the intended lane
under the following circumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane marker from the road because the
lane marker is covered with dust or
sand.
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.

LKA System Function Change
The driver can change LKA to Lane
Departure Warning from the LCD
display. Go to the 'User Settings →
Driver Assistance →Lane Safety →
Active LKA/Lane Keeping Assist
/Lane Departure Warning/Off'.
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.
Standard LKA
This 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 con-
trol the steering wheel, when the
vehicle is about to deviate out of the
lane.
Lane Departure Warning
LDW system 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.
Off
If you select "Off", the LKA system is
deactivated.
