Your Driving and the Road If You're Caught in a Blizzard (CONT) If You're Stuckin Deep Snow Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat thisonly when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuelas long as you can. To help keep warm, you can get out of the vehicle anddo some fairly vigorous exercises every half-hour or so until help comes. This manual explainshow to get the vehicle out of deep snow without damaging it. See the Index under Rocking Your khicle. Run your engine onlyas long as you 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 h e 1 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 a while. 166
