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. I
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.

Headlamp Aiming
The aim of your vehicle’s headlamps can be adjusted
by using aim tips located on the outer surface of
the
lens. The aim has been pre-set at the factory and
should need
no further adjustment.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the
low beam
may be necessary
if it is difficult to see lane markers
(for horizontal aim), or
if oncoming drivers flash
their high beams at you (for vertical aim). If you believe
your headlamps need to be re-aimed, it
is recommended
that you take your vehicle to the dealer for assistance.
