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 Kia dealer.
WARNING - Engine exhaust
Do not inhale exhaust fumes or leave your engine running in an enclosed area for a prolonged time.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxiation.

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 the highest speed.
