Exhaust may enter the vehicle if:

(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.
• There are holes or openings in the vehicle
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.
