Engine Exhaust

Warning
Engine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
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 exhaust system
has been modified, damaged,
or improperly repaired.
Warning (Continued)
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 the vehicle with the
engine running in an enclosed area
such as a garage or a building that
has no fresh air ventilation.
