sounds strange or different.
The exhaust system leaks
due to corrosion or damage.
WARNING (Continued)
The vehicle exhaust system
has been modified, damaged,
or improperly repaired.
There are holes or openings
in the vehicle body from
damage or aftermarket
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 with the engine
running in Extended Range Mode
in an enclosed area such as a
