A CAJTldN:
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.
