Run your engine onlyas long as you must. This saves fuel. When you run the engine, makeit go alittle 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 battery to restart the vehicle, and possibly for signaling later on with your headlights. Letthe heater run for awhile. Then, shut the engine off and closethe window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and dosome fairly vigorous exercises every half hour or so until help comes.
