The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airflow or tail pipes).
•
The exhaust smells or sounds strange or
different.
•
The exhaust system leaks due to corrosion or
damage.

The vehicle’s exhaust system has been
modified, damaged or improperly repaired.
•

body from damage or after-market
modifications that are not completely sealed.
If unusual fumes are detected or if it is suspected
that exhaust is coming into the vehicle:
•
Drive it only with the windows
completely down.
•
Have the vehicle repaired immediately.
Never park the vehicle with the engine running in
an enclosed area such as a garage or a building
that has no fresh air ventilation.
