WARNING
nENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open thewindows immediately.•Do not inhale exhaust fumes.Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyx‐iation.
•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 thevehicle, we recommend that the system be checked by an authorized Kia 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. Never run the engine inyour garage any longer than it takes to start the engine and back the vehicle out.
•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 openarea with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interi‐or.
If you must drive with the tailgate/trunk open because you are carrying objects that make this necessary:1.Close all windows.
2.Open side vents.
3.Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the wind‐shield are kept clear of snow, ice, leaves or other obstructions.
