A/C Mode

Air is directed to the A/C outlets with bleed airflow to the heater outlets. If previously in the AUTO-MAX A/C mode, the air inlet valve slowly closes in order to provide 100% outside air. The A/C clutch engages when the outside temperature is above 6°C (42°F) in order to help dehumidify the air.
