{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 cannot 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 the exhaust
pipe. And check around again
from time to time to be sure
snow does not collect there.
Open a window just a little on
the side of the vehicle that is
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 the
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.
If Your Vehicle is Stuck
in Sand, Mud, Ice,
or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 8-28.
{CAUTION
If you let your vehicle’s tires
spin at high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment re or
other damage. Spin the wheels
as little as possible and avoid
going above 35 mph (55 km/h)
as shown on the speedometer.
For information about using tire
chains on the vehicle, seeTire
Chains on page 9-62.
