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, we recommend
that the exhaust system be 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 liftgate 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.

components found in the interior furnishings in a vehicle, contain or emit harmful
chemicals known to the State of California to cause cancer and birth defects and

ignition switch
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the ignition switch or related
parts. Unexpected and sudden
vehicle movement can occur.
• NEVER reach through the steering
wheel for the ignition switch, or any
other control, while the vehicle is in
motion. The presence of your hand
or arm in this area may cause a loss
of vehicle control resulting in an
accident.
Key ignition switch (if equipped)
OTM060051L[A] : LOCK, [B] : ACC
[C] : ON, [D] : START
Whenever the front door is opened, the
ignition switch will illuminate, provided
the ignition switch is not in the ON
position. The light will go off immediately
when the ignition switch is turned on or
go off after about 30 seconds when the
door is closed. (if equipped)
WARNING
• NEVER turn the ignition switch to
the LOCK or ACC position while the
vehicle is in motion except in an
emergency.
This will result in the engine turning
off and loss of power assist for the
steering and brake systems. This may
lead to loss of directional control and
braking function, which could cause
an accident.
• Before leaving the driver’s seat,
always make sure the gear is in the
P (Park) position, apply the parking
brake, and turn the ignition switch to
the LOCK position.
Unexpected vehicle movement may
occur if these precautions are not
followed.
NOTICE
Never use aftermarket keyhole covers.
This may generate start-up failure due
to communication failure.
