Manual Control If you prefer to manually control the heating, cooling and ventilation in your vehicle, you can select airflow direction, fan speed, outside or recirculated air, air compressor and temperature operation with the following: AIR FLOW: This control has several settings to control the direction of airflow when the system is not in AUTO. To access the various modes available, continue to press the AIR FLOW rocker button up or down until the desired mode appears in the display: WINDSHIELD/FLOOR: This setting directs half of the air to the floor ducts and half to the defroster and side window vents. The air conditioning compressor will run automatically in this setting unless the outside temperature is below 40_F (4_C). MID/FLOOR: This setting directs half of the air through the instrument panel outlets. Most of the remaining air is directed through the floor ducts and a little to the defroster and side window vents. MID: This setting directs air through the instrument panel outlets. FLOOR: This setting sends most of the air through the ducts near the floor. The rest comes out of the defroster and side window vents. When in this setting and the RECIRC setting, the windows can fog up. See "RECIRC" in the Index. FRONT: This setting brings in outside air and directs most of the air through the defrost vent. Some of the air also goes to the floor ducts and the side window defogger outlets. The indicator on the button will light and WINDSHIELD will be lit in the display. The air conditioning compressor will run automatically in this setting unless the outside temperature is below 40_F (4_C). VENT: This setting turns the air conditioning compressor on and off. The indicator is lit when the compressor is turned off. Recirculation is not permitted when the compressor is off. The system will try to control the temperature automatically, but without the compressor. VENT is not permitted in FRONT defrost mode. If the VENT button is pushed while in FRONT defrost mode, the indicator will light for one second and then turn off. 3-7
