(AUTO RECIRCULATION): If the AUTO position
is selected on either the fan or mode control, the system
will automatically control 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 button when the
light is lit. The next time AUTO fan or mode is selected,
the air inlet will reset back to AUTO operation.
