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.
