Does anyone know how to use the heating system on the 2023 model 285 extended range in winter? With winter approaching, for short trips in the city, I mostly use pure electric and rely on PTC for heating. But what about using the range extender on the highway? I'm unsure if the range extender's heat can be used for heating. After starting the range extender, should I choose the Auto mode for the air conditioning or directly select the heating mode?
