Care of Your Compact Discs
KO557
Handle discs carefully. Store them in their original cases or other protective
cases and away
from direct sunlight and dust. If the surface of a disc is
soiled, dampen a clean,
soft cloth in a mild, neutral detergent solution and
clean
it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling discs. Pick up discs
by grasping the outer edges
or the edge of the hole and the outer edge.

sure the vehicles aren’t touching each other.
If they are, it could cause a
ground .connection you don’t want. You wouldn’t be able
to start your
vehicle, and the bad grounding could damage the electrical syst\
ems.
1 CAUTION
I
A You could be injured if the vehicles roll. Set the parking brake firmly
b on each vehicle. Put an automatic transmission in P (Park) or a
I manual transmission in N (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both \
batteries.
And
it could save your radio!

4. Open the hoods and locate the batteries. Find the positive (t) and the
negative
(-) terminals on each battery.
1 CAUTION
A 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.
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
I with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing in\
sulation. If
they do, you could get a shock. The vehicles could be damaged\
, too.
Before you connect the cables, here are some things you should\
know.
Positive
(t) will go to positive (+) and negative (-) will go to negative
(-) or a metal engine part. Don’t connect (t) to (-) or you’ll get a
short that would damage the battery and maybe other parts,
too.
