3-20 Instrument Panel [ (Floor): Air is directed to the floor outlets, side window outlets, and defroster. Recirculation is not available in this mode. / (Floor/Defog): This mode clears the windows of fog and moisture. Air is directed to the windshield, side window, and floor outlets. The system runs the air conditioning unless the outside temperature is near freezing or below. Recirculation is not available in this mode. # (Air Conditioning): Press to turn the air conditioning system on or off. An indicator light comes on when the air conditioning is turned on. This system cools and dehumidifies the air entering the vehicle. The air conditioning will not function if the fan is turned off. If air conditioning is selected with fan off, the indicator light flashes three times and then turns off. A slight change in engine performance may occur when the air conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature. The air conditioning system removes moisture from the air, so a small amount of water might drip under the vehicle while idling or after turning off the engine. This is normal. @ (Recirculation): Press to turn the recirculation mode on or off. An indicator light comes on when the recirculation is on. This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to prevent outside air and odors from entering the vehicle. Recirculation is available in the bi-level and vent modes. This mode cannot be selected while in the floor, floor/defog or defrost modes. If you try to select the recirculation mode, the indicator flashes three times indicating it is not available in that mode. When the recirculation mode is turned on, the air conditioning turns on automatically. When it is hot enough outside, the recirculation mode may turn on automatically to help improve cooling performance. The indicator light will be lit to show this mode is active. If the recirculation button is pressed while in this mode, the light flashes three times and stays on to indicate that recirculation may not be shut off. (Defrost): This mode clears the windshield of fog or frost more quickly. Air is directed to the windshield and side window outlets. The system runs the air conditioning system unless the outside temperature is near or below freezing. Recirculation is not available in this mode. Do not drive the vehicle until all the windows are clear. 0
