Snow can trap exhaust gases unc,.’ 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
on!y
as
!nng
as
you
must.
This
saves
fuel. When you run the engine, make
it
go a little
faster than just iaie. 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 on with your headlamps. Let the
heater run for a while.
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.
