{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Runyour engine only as long as you must. This saves
fuel.When you run the engine, make it go a little faster
thanjust idle. That is, push the accelerator slightly. This
usesless fuel for the heat that you get and it keeps the
batterycharged. You will need a well-charged battery to
restartthe vehicle, and possibly for signaling later on with
yourheadlamps. Let the heater run for a while.
Then,shut the engine off and close the window almost all
theway to preserve the heat. Start the engine again and
repeatthis only when you feel really uncomfortable from
thecold. But do it as little as possible. Preserve the fuel
aslong as you can. To help keep warm, you can get out
ofthe vehicle and do some fairly vigorous exercises
everyhalf hour or so until help comes.
