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 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.
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.
