WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, have the exhaust
system checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at "Fresh" and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan
control set to high.

Before Entering the Vehicle
• Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven
wear and damage.
• Check under the vehicle for any sign
of leaks.
• Be sure there are no obstacles behind
you if you intend to back up.
Before Starting
• Make sure the hood, the trunk, and
the doors are securely closed and
locked.
• Adjust the position of the seat and
steering wheel.
• Adjust the inside and side view
mirrors.
• Verify all the lights work.
• Fasten your seatbelt. Check that
all passengers have fastened their
seatbelts.
• Check the gauges and indicators
in the instrument panel and the
messages on the instrument display
when the ignition switch is in the ON position.
• Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions: • ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to "Seat
Belts" in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.
• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink alcohol or take drugs and
drive.
Drinking alcohol or taking drugs and
driving is dangerous and may result in
an accident and SERIOUS INJURY or
DEATH. Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don't drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
Before Driving

•
Do not place objects on the
dashboard that reflects light such as
mirrors, white paper, etc. This may
prevent LKA system from functioning
properly.
• Always have your hands on the
steering wheel while LKA system is
activated. If you continue to drive
with your hands off the steering
wheel after the “Keep hands on
steering wheel” warning message
appears, the system will stop
controlling the steering wheel.
• The steering wheel is not
continuously controlled so if the
vehicle speed is at a higher rate
when leaving a lane the vehicle may
not 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.
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
64 km/h (40 mph) 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 64
km/h (40 mph).
- 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.

1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of
the fuse panel cover to locate the
suspected fuse location.
ODN8089016
5. Pull the suspected fuse straight out. Use the removal tool provided in the
engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. Push in a new fuse of the same
rating, and make sure it fits tightly in
the clips. If it fits loosely, consult an
authorized HYUNDAI dealer.
In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit you may not need for
operating the vehicle.
If the headlamps or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.
