• Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the Recirculation button. However,
under certain conditions in automatic the system is
blowing air out of the defrost vents. When these
conditions are present, and the Recirculation button is
pressed, the indicator will flash and remain off. This
tells you that you are unable to go into Recirculation
mode at this time. If you would like to go to Recircu-
lation mode, you must first move your mode knob to
Panel, Panel/Floor, or Floor, then press the Recircula-
tion button. This feature will reduce the possibility of
window fogging.
