AUTO (Automatic Air Conditioning): If AUTO
is selected on the fan or mode control, the
system will automatically control 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 will be 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 will
run automatically in damp cool conditions.
h (Auto Recirculation): If AUTO 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 outside air button. The
next time AUTO fan or mode is selected, the
air inlet will reset back to AUTO operation.
Manual Operation

If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment air
filter may need to be replaced. For more
information, see Passenger Compartment Air Filter
on page 192 and Scheduled Maintenance on
page 442.
