Heating For the quickest results, press the recirculate button and move the mode knob to the floor mode. Turn the temperature knob clockwise for warmer air and turn the fan knob toward HI. You should switch to outside air once in a while to avoid stale air and cloudy windows. To prevent cold air from blowing in and to increase air flow to the floor area, you may shut off the outer dash vents by using the thumbwheels. You may want to use bi-level heating on cool but sunny days. This setting directs outside air toward your body and warmer air toward your feet. Using outside air, turn the mode knob to the bi-level mode. Turn the temperature knob counterclockwise and the fan knob toward HI. Defogging and Defrosting When the mode knob is turned to either the defog or defrost mode, outside air will be selected automatically. This is used to clean up the front windshield more quickly. Turn the temperature knob clockwise and the fan knob toward HI. When the windshield is clear, turn down the fan speed. If you wish to return to the recirculate mode, the recirculate button can be set when the mode knob is set on full defog or full defrost. The indicator light will come on. D Recirculate cannot be set partway between floor and defog, and D Recirculate cannot be set partway between defog and defrost. However, when the mode knob is turned to another position, outside air will be selected automatically. To defog the windshield and side windows, use outside air and turn the mode knob to defog. 3-4
