An energy management technique for an electrified vehicle controls an electrified powertrain to maintain a fuel reserve in a fuel tank, wherein the fuel reserve is a threshold amount above a minimum amount of fuel that is kept in the fuel tank while indicating that the fuel tank is fully depleted, detects an operating condition of the electrified vehicle when (i) the fuel tank is depleted down to the fuel reserve and (ii) a battery system state of charge (SOC) is at or below a minimum SOC propulsion threshold and, in response to detecting the electrified vehicle operating condition, temporarily powers the engine using the fuel reserve in the fuel tank and utilize the engine to support a heating system of the electrified vehicle configured for at least window heating and/or defrosting.
