Sn'ow 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 can't see it or smell it, so you might not
know it is
in your vehicle. C1,ear 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
doesn't collect th'ere.
Open
a
window just a little on the side of the
vehicle that's away from the wind, This will help
keep CO out.
Run your engine only as 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 fuel for the heat that you get and it keeps the
battery charged. You will nee'd 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 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
do
some fairly vigorous exercises
every half hour o r so
until help comes.
