A vehicle includes an internal combustion engine having an auto stop function, an electric pump motor drivably coupled to a transmission pump and a heat exchanger pump, and at least one controller. The controller is configured to control the pump motor to operate the transmission pump to supply hydraulic pressure to a transmission, and to operate the heat exchanger pump to provide flow from the engine to a heater core radiator in response to the engine being auto stopped.
