To facilitate faster cabin cooling, prior to engine start leave the
cabin doors open for a short time to allow hot air to escape
cabin.
For maximum cabin cooling, set Airflow Selector to fan speed
3, Vent Selector to feet/panel/defrost position, and
Temperature Selector to recirculation mode. Additionally,
ensure the instrument panel and armrest eyeball outlets are
open. (See Figure - 1)
