2. Get the vehicles close enough so the jumper cables
can reach, but be 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 systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on each vehicle. Put your
vehicle
in PARK (P).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets. Turn
off all
lamps that aren’t needed as well as radios. This will
avoid sparks and help save both batteries. In
addition, it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repair wouldn’t be covered by
your warranty.

4. Open both hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on
each battery.
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.
Be sure the battery has enough water.
You don’t
need
to add water to the ACDelco 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 a metal
engine part. Don’t connect positive
(+) to
negative
(-) or you’ll get a short that would damage
the battery and maybe other parts too.
6. Connect the red
positive
(+) cable to the
positive
(+) terminal of
the vehicle with the
dead battery.
7. Don’t let the other end
touch metal. Connect
it
to the positive (+)
terminal of the
good battery.
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
1 connection is just as
good there, but the
chance
of sparks getting
back to the battery
is
much less.
10. Now start the vehicle with the good battery and run
the engine for awhile.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.
1 1. Try to start the vehicle with the dead battery. If it
won’t start after a few tries, make sure all
connections are good. If it still won’t start, it
probably needs service.

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque
wheel nuts in the
proper sequence to
GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this manual
under Part
C “Periodic Maintenance Inspections.”
Brakc Jedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be
of top quality and work well
together
if the vehicle is to have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When you replace parts of your braking
system
-- for example, when your brake linings wear
down and
you have to have new ones put in -- be sure
you get new approved GM replacement parts.
If you
don’t, your brakes may
no longer work properly. For
example,
if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you’ve come to expect can change in many
other ways if someone puts
in the wrong replacement
brake parts.
Battery
Every new vehicle has an ACDelco Freedom@ battery.
You never have to add water to one of these. When it’s
time for a new battery, we recommend an ACDelco
Freedom battery. Get one that has the replacement
number shown on the original battery’s label.

If you’re not going to drive your vehicle for 25 days
or more, remove the black, negative
(-) cable from
the battery. This will help keep your battery from
running down.
A CAUTION:
Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are off and the engine isn’t running. See “Replacement
Bulbs”
in the Index.
For any bulb changing procedure not listed
in this
section, contact your GM dealer’s service department.
High Intensity Discharge (HID) Lighting
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around
a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index.
I A CAUTION: I
The low beam High Intensity Discharge lighting
system operates at a very high voltage.
If you try
to service
any of the system components, you
could be injured. Have your dealer or
a qualified
technician service them.
