Guarding Against Exhaust Fumes
Carbon monoxide, although colorless and
odorless, is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
If you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes.
If your vehicle has rear windows and doors that
were installed as part of a van conversion, close
them while it is running. This prevents exhaust
fumes from being drawn into the passenger
compartment.
Have the exhaust and body ventilation systems
checked whenever:
your vehicle is raised for service
the sound of the exhaust system changes
your vehicle has been damaged in a collision
Improve your ventilation by keeping all air inlet
vents clear of snow, leaves, and other debris.
If the engine is idling while you are stopped in
an open area for long periods of time, open the
windows at least one inch (2.5 cm). Also, adjust
the heating or air conditioning system to bring
in outside air.
HEATING — Set fan speed at MEDIUM or
HIGH, the function selector knob on VENT,
FLOOR, MIX, or the DEFROST symbol and
the temperature control knob on any desired
position.
