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.
