Manual Operation You may override the automatic airflow distribution by turning the AUTO-PUSH knob. After you turn this knob, the comfort setting will be displayed for five seconds, then the outside temperature will be displayed. The fan control will remain in the automatic control mode unless you turn the AUTO FAN knob to select a manual fan speed. PANEL: This setting directs airflow through the upper air outlets located in the instrument panel. BI-LEVEL: This setting directs the airflow through both the panel air outlets and the lower floor outlets. There is also a small amount of air directed to the front defroster and the side window defrosters. FLOOR: This setting directs most of the airflow to the lower floor outlets with some airflow directed to the side window defrosters. There is also a small amount of airflow directed to the front defroster. DEFOG: This setting directs the majority of the airflow to the lower floor outlets and the front defroster. A small amount of airflow is directed to the side window defroster outlets. This mode can be useful to remove the moisture from the inside of the windshield when the outside temperature is cold or the humidity is high. Be sure the A/C indicator light comes on to allow the air compressor to come on automatically to help dehumidify the air. DEF (Defrost): This setting directs the majority of the airflow to the windshield with some airflow to the side window defrosters and lower floor outlets. To increase the fan speed, turn the AUTO FAN knob clockwise. If defrost is selected from AUTO mode, your automatic electronic climate control system will automatically increase the defrost outlet temperature and fan speed. For maximum front defrost performance under extreme icing or frosting conditions, increase the temperature setting to 90_F (33_C) and increase the fan speed to high. Even though A/C is not selected, in front defrost mode the A/C compressor will run automatically at temperatures over approximately 40_F (4_C) to improve windshield clearing performance. This dehumidifies the air to help dry the windshield. Even though the compressor may be running, the A/C indicator light will not come on in front defrost unless you select A/C. 3-5
