Air Conditioning #(Air Conditioning): Press this button to turn the air conditioning (A/C) compressor on and off. The snowflake symbol will appear on the display when the A/C is on. Pressing this button when the outside temperature is too cool for air conditioning to be effective will make the snowflake symbol flash three times and then turn off to let you know that the air conditioning mode is not available. If the air conditioning is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the snowflake symbol will turn off to let you know that the air conditioning mode has been canceled. On some vehicles, when you turn the air conditioning off, this symbol will appear on the display. If your vehicle does not have this symbol, the snowflake symbol will turn off to let you know the air conditioning is off. When air conditioning is selected or in AUTO mode, the system will run the air conditioning automatically to cool and dehumidify the air entering the vehicle. If you select A/C off while in front defrost, defog or recirculation, the A/C snowflake symbol will turn off, but the A/C compressor will still run to help prevent fogging. 3-26 On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best.

To warm or cool the air delivered, turn the temperature knob to the desired setting. In AUTO mode the system will cool and dehumidify the air inside the vehicle. Also while in AUTO mode, the system will maximize its performance by using recirculation as necessary. Heating On cold days when using manual operation of the automatic system, choose floor mode to deliver air to the floor outlets. To warm or cool the air delivered, turn the temperature knob to the desired setting. If you want to use the automatic mode, press AUTO and adjust the temperature by turning the temperature knob. The heater works best if you keep the windows closed while using it. ^ (Air Conditioning Off):
