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.

NEVER drink or take drugs and
drive.
Drinking or taking drugs and
driving is dangerous and may
result in an accident and SERI-
OUS 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, percep-
tions and judgment. Just one
drink can reduce your ability to
respond to changing conditions
and emergencies and your reac-
tion time gets worse with each
additional drink.
Driving while under the influ-
ence of drugs is as dangerous
or more dangerous than driving
under the influence of alcohol.(Continued)
WARNING (Continued)
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.
