keep warm, but be careful.

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 can’t 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
doesn’t collect there.
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 (or batteries) charged. You will need a
well-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater
run
for awhile.
If you have a diesel engine,
you
may have to run it at a
higher speed to get enough heat. 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 or
so
until help comes.
