Run your engine only a s long a s YOLI must. This saves fuel. When you run the engine, make it go a 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 battery to restart the vehicle. and possibly for signaling later on with your headlamps. Let the heater run for awhile. Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortabl e from the cold. But do it a s little a s possible. Preserve the fuel a s long a s you can. To help keep warm? you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes. 4-27
