A CP ""IC\:
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 charged. You will need
a we.11-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 uncornfortable
from the
cold. BLI~ 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.

4. Open both hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
/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 battery has enough water. You don’t
need to add water to the Delco Freedom@ battery
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’ll get a
short that would damage the battery and maybe other
parts too. And don’t connect the negative
(-) to
negative
(-).
6. Connect the red positive
(+) cable to the positive
(+) terminal of the
vehicle with the
dead battery.

Rear Axle What to Use
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler pl~~g hole. Refer
to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended
Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL@ extended life coolant.
J
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
