Claim 10:
11. A method, comprising:
in a first mode, operating a powertrain and a heating, ventilation, and air conditioning (HVAC) system to provide air of a maximum threshold temperature to a vehicle cabin, operating an ultraviolet germicidal irradiation (UVGI) system, operating one or more heated surfaces that include electronically controlled heating elements, closing a sun shade responsive to a sun load threshold, wherein the sun load threshold is set based on ambient temperature to be relatively higher at lower ambient temperatures, increasing an engine idle speed, and switching off an engine cooling fan from an already running position even with engine coolant temperature increasing to a higher engine coolant temperature; and
in a second mode, operating the powertrain and the HVAC system to provide air within a threshold temperature range to the vehicle cabin, the threshold temperature range including temperatures lower than the maximum threshold temperature, and not operating the UVGI system.
