Carbon monoxide (CO) gas is toxic. Breathing CO may cause unconsciousness and death.
Engine exhaust contains carbon monoxide that 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 may cause unconsciousness and death by asphyxiation.
Make 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 purposes. If you hear a change in the sound of the exhaust or 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 an extended period of time with people inside the vehicle.
If it is necessary to idle the engine for a long time 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 ensure 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.
