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.

tentive the driver is.
The number decreases when the driver does not take a break for a
certain period of time. The number increases when the
driver attentively drives for a cer-
tain period of time.
When the driver turns on the sys- tem while driving, it displays 'Last
Break time' and level.
Take a break
The "Consider taking a break“message appears on the cluster
LCD display and a warning sounds
to suggest that the driver take a
break, when the driver’s attention
level is below 1. The Driver Attention Warning
(DAW) system will not suggest a
break, when the total driving time
is shorter than 10 minutes.
Resetting the System
The last break time is set to 00:00and the driver's attention level is
set to 5 (very attentive) when the
driver resets the Driver Attention
Warning (DAW) system.
The Driver Attention Warning (DAW) system resets in the follow-
ing situations.
- The engine is turned OFF.
- The driver unfastens the seat belt and then opens the driver's
door.
- The vehicle is stopped for more than 10 minutes.
The Driver Attention Warning (DAW) system operates again,
when the driver restarts driving.

pedal according to the road and driv-
ing conditions.
Always check the road conditions.
Do not rely on the warning chime.
To resume Smart Cruise Control set speed
If any method other than the cruise
toggle switch was used to cancel
cruising speed and the system is still
activated, the cruising speed will
automatically resume when you
push the toggle switch up (RES+) or
down (SET-).
If you push the toggle switch up
(RES+), the speed will resume to the
recently set speed. However, the
vehicle speed must be over 5 mph
(10 km/h).
i
OIK057096NTo avoid collisions, always be

What to do in an emergency
If the Engine Stalls While
Driving
Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
Turn on your hazard warning flash- er.
Try to start the engine again. If your vehicle will not start, contact an
authorized HYUNDAI dealer or
seek other qualified assistance.
If the Engine Stalls at a
Crossroad or Crossing
If the engine stalls at a crossroad or
crossing, if safe to do so, move the
shift lever to the N (Neutral) position
and then push the vehicle to a safe
location.
If You Have a Flat Tire While
Driving
If a tire goes flat while you are driv-
ing:
Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
When the vehicle is stopped, press the hazard warning flasher button,
move the shift lever into P(Park),
and apply the parking brake, and
place the ignition switch in the
LOCK/OFF position.
Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic. When changing a flat tire, follow
the instructions provided later in
this chapter.

What to do in an emergency
Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label.
If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
