A 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. Youxan't see
it or smell it, so you might not
~QW 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 charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling
later OIZ
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 or so until help comes.
