An air handling system (108) controls delivery of fresh air and recirculated air to a cabin (106) of the vehicle. The control system comprises one or more controllers configured to: receive a signal indicative of a number of occupants within the vehicle cabin; determine a maximum period for operating the air handling system in an air recirculation mode based on the indicated number of occupants; and output one or more control signals to the air handling system for terminating the air recirculation mode once the maximum period has elapsed from initiation of the air recirculation mode.
