ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical systems.
CAUTION
A You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in
P (Park) or a
manual transmission in
N (Neutral).
If you have a four-wheel-drive vehicle, be sure the transfer case is
not 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!

I jou leave a radio on, it could be badly damaged. The repairs woulc
be covered by your warranty.
4. Open the hoods and locate the batteries.
Find the positive
(t) and negative (-) terminals on each battery,
CAUTION
A Using a match near a battery can cause battery gas to explode.
b 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 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 bum 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. c
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 things you should\
know.
Positive (t) will go to positive (t) 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.
A Fans or other moving engine parts can injure you badly. Keep your
h hands away from moving parts once the engines are running.
6. Connect the red positive (t) cable to the positive (t) terminal of the
vehicle with the dead battery. Use a remote positive
(+) terminal if the
vehicle has one.

7. Don’t let the other end touch metal. Connect it to the positive (+)
terminal of the good battery. Use a remote positive (+) terminal if the
vehicle has one.
8.
Now connect the black negative (-) cable to the good battery’s negative
(-) terminal.
Don’t let the other end touch anything until the next step. The other end
of the negative cable
doesn’t go to the dead battery. It goes to a heavy
unpainted metal part on the engine
of the vehicle with the dead battery.
9. Attach the cable at least 18 inches (45 cm) away from the dead battery,
but not near engine
parts that move. The electrical connection is just as
good there, but the chance
of sparks getting back to the battery is much
less.

Service & Appearance Care
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due to heavy snow, etc., the wiper will stop until the
motor cools.
If the overload is caused by some electrical problem and not
snow, etc., be sure to get
it fixed,
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other power
accessories. When the current load
is too heavy, the circuit breaker opens
and
closes, protecting the circuit until the problem is fixed or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line fuse
in the battery feed wire. This fuse is near the junction
block. See “Trailer
Wiring Harness” in the Index for more information.

The fuse block is in
the instrument panel on the driver’s side.
You can remove fuses with a fuse extractor, if you have one. To remove
fuses
if you don’t have one, hold the end of the fuse between your thumb
and index finger and pull straight out.
Be sure to use the correct fuse.
If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. Just pick
some feature of your vehicle that you can get along without-like the radio \
or
cigarette lighter-and use
its fuse, if it is of the value you need. Replace it
as
soon as you can. See “Fuses and Circuit Breakers” in the Index for more
information.
