If the AUTO position is selected on the fan or mode
control, the system automatically controls the air
conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator light
is lit when the system is operating automatically,
even at near freezing outside temperatures. Press
the A/C button on the fan control to turn off the A/C.
For improved window clearing performance in defog or
defrost modes, the A/C compressor runs automatically.
h
(AUTO RECIRCULATION): If the AUTO
position is selected on either the fan or mode control,
the system automatically controls the air inlet to
supply fresh outside air or recirculate the interior
air to cool the car faster. The indicator light on the
recirculation button will light whenever the system
switches to recirculation. You may force outside air
by pressing the recirculation button when the light is lit.
For vehicles without rear climate controls, press the
outside air button to force outside air. The next
time AUTO fan or mode is selected, the air inlet will
reset back to AUTO operation.
