Run your engine only as long as you must. This saves fuel. When you run the engine, make it goa little faster than just idle. That is, push the accelerator slightly.This uses less fuel for the heat that you get and it keeps the battery charged.You will need a well-charged batteryto restart the vehicle, and possibly for signaling later on with your headlamps.Let the heater runfor a while. Then, shut the engine off and close the window almost all the way to preserve theheat. Start the engine again and repeat this only when you feel really uncomfortable from the cold.
