1998 GMC SAVANA check engine light

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.
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 (or batteries) charged.
You will need a
well-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater
run for a while.
If
you have a diesel engine, you may have to run it at a
higher speed to get enough heat. 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.

A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
Be sure the batteries have enough water. You
don’t need to add water to the ACDelco
Freedom@ battery (or batteries) installed in
every new
GM vehicle. But if a battery has filler
caps, be sure the right amount of fluid is there. If
it is
low, add water to take care of that first. If
you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
5. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged, too.
Before
you connect the cables, here are some basic
things
you should know. Positive (+) will go to
positive
(+) and negative (-) will go to an unpainted
metal engine part or
a body metal surface. Don’t
connect positive
(+) to negative (-) or you will get a
short that would damage the battery and maybe other
parts, too. And don’t connect the negative
(-) to
negative
(-).
Fans or other moving engine parts can injure you
badly. Keep your hands
away from moving parts
once the engine is running.
