I
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. 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 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.
