Instrument Panel 3-23 6 (Floor): Air is directed to the floor outlets, with some of the air directed to the windshield, side window, and second row floor outlets. In this mode, the system uses outside air. This mode clears the windows of fog or moisture. Air is directed to the windshield, floor outlets, and side window vents. When this mode is selected, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is less than 40°F (4°C). Do not drive the vehicle until all the windows are clear. - (Defog): 0 (Defrost): Press to turn the defrost on or off. This mode quickly clears the windshield of fog or frost. Air is directed to the windshield, side window, and floor vents. In this mode, outside air is pulled inside the vehicle. The air conditioning system runs automatically in this setting, unless the outside temperature is less than 40°F (4°C). Do not drive the vehicle until all the windows are clear. While in defrost mode, if the PASS button is pressed, the PASS button indicator flashes three times to show that the passenger climate control system cannot be activated. If the passenger temperature buttons are adjusted while in defrost mode, the driver temperature indicator will change. The passenger temperature will not be displayed. Air Conditioning # (Air Conditioning): Press to turn the air conditioning (A/C) on and off. An indicator light comes on when A/C is on. The A/C does not work when the outside temperature is below 40°F (4°C). If # is pressed the indicator flashes three times and turns off to show that the A/C mode is not available. If the A/C is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the A/C indicator turns off to show that the A/C mode has been canceled. On hot days, open the windows briefly to let hot inside air escape. This helps reduce the time it takes for the interior of the vehicle to cool down.
