Buick 2000 Park Avenue Owner's Manual page 162

During stops, when driving slow, or when the engine
is first started after a short trip, the outside temperature
reading can be affected by road or engine heat.
Also, starting the engine within a short time after the
vehicle has been running will affect the reading. To
ensure proper automatic climate control operation, the
outside temperature display may not update as quickly
as expected.
Sun and temperature sensors automatically adjust the
air temperature, the airflow direction and the fan speed
to maintain your comfort setting. The system may
supply cooler air to the side toward the sun. Be careful
not to put anything over the sensors on top of the dash.
Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the red arrow. If you want a
cooler comfort level, push the blue arrow. Your comfort
setting is shown in the display.
Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed,
push the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators on the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Press the up or down arrow on the AIR FLOW button to
cycle through the available modes.
