FAN: Press the up arrow to increase fan speed and the down arrow to decrease fan speed. The fan must be turned on for the air conditioning compressor to operate. TEMP (Temperature): The TEMP switch sets the temperature for the entire cabin when the light on the DUAL light button isn't lit. When the DUAL button light is lit, the TEMP switch sets the temperature for the driver only. Press the up arrow to raise the temperature and press the down arrow to lower the temperature. The display will show your selection for a few seconds, then the outside temperature will be displayed. If you push the AUTO button, the system will control the fan speed and airflow and will maintain the selected temperature. 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 briefly and then turn off. RECIRC (Recirculation): This setting recirculates much of the air inside your vehicle. This setting is not permitted in FRONT defrost mode and is only permitted in WINDSHIELD/FLOOR mode if the compressor is turned on. The indicator light will be lit when recirculation is engaged, but will light briefly and then turn off if selected when not permitted. Operating the climate control system in the RECIRC mode may cause fogging of the vehicle's windows when the weather is cold and damp. To clear the fog, switch the system to either WINDSHIELD/FLOOR or WINDSHIELD mode and increase the fan speed. To avoid re-fogging of the windows, operate the system with RECIRC off. 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 seen on the display. The air conditioning compressor will run automatically in this setting unless the outside temperature is below 40_F (4_C). 3-5
