It is best to leave the system in Fresh
Air mode under almost all conditions.
Keeping the system in Recirculation
mode, particularly with the A/C off,
can cause the windows to fog up.
Switch to Recirculation mode when
you are driving through smoky or
dusty conditions, then switch back to
Fresh Air mode when the condition
clears.
The outside air intakes for the
heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.
