Pressing the recirculation button will cancel outside air operation. To return to normal system operation and to prevent stale passenger compartment air, be sure to return to the outside air position. Recirculation will not be available in floor, blend or defrost modes. This helps reduce window fogging. If the recirculation button is pressed in theses modes, the LED indicator for recirculation will flash three times indicating that forced outside air is activated and recirculation is not available. If the air conditioning system is activated and system demand is high in situations such as city traffic, idling, or very hot weather, the system will automatically switch from outside air to recirculation. The LED indicator will not change. After the demand on the system is not so great, the system will return to outside air. (A/C): Press this button to turn the air conditioning on and off. The system will cool and dehumidify the air inside the vehicle when the A/C light is on. When in AUTO, the A/C is automatically engaged when necessary. Air conditioning will be automatically disabled when the outside temperature drops below a level which air conditioning is ineffective.
