Driving Your Vehicle
Make sure the exhaust system has no leaks.
The exhaust system should be inspected whenever the vehicle is lifted for oil changes or for any other purpose. If you notice a change in exhaust sound or if you drive over something that strikes the underbody, have the exhaust system inspected by an authorized Kia dealer as soon as possible.
WARNING - Engine Exhaust
Do not breathe engine exhaust gases or leave the engine running in an enclosed area for a long period.
Exhaust gases contain carbon monoxide, a colorless, odorless gas that can cause loss of consciousness and death by asphyxiation.
WARNING - Open Trunk/Tailgate
Do not drive with the trunk/tailgate open.
Toxic exhaust gases may enter the passenger compartment. If you must drive with the trunk/tailgate open, perform the following:
1. Close all windows.
2. Open the side vents.
3. Set the air intake control to Fresh, the airflow mode control to Floor or Face, and the blower to maximum speed.
