Recirculation Button
When the indicator in the button is
on, air from the vehicle's interior is
sent throughout the system again.
When the indicator is off, air is
brought in from the outside of the
vehicle (fresh air mode).
The outside air intakes for the
heating and cooling system are at
the base of the windshield. Keep this
area clear of leaves and other debris.
The system should be left 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
driving through dusty or smoky
conditions, then return to fresh air
mode.
