Run
your engine only
as
long
as
YOLI
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
o
uses less fuel for the heat that you get and
it
keeps
the
battery charged. You
will
need
a
well-charged battery
t
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 uncomfortabl e
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.
