climate settings BUICK LUCERNE 2006 Owner's Manual

After your vehicle is started, the display will show the
interior temperature settings.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
AUTO
#(Automatic Air Conditioning):If the
AUTO position 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 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.
