Replacing Brake System Parts
The braking system on a 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 brake parts. When you
replace parts of the braking system — for example,
when the brake linings wear down and you
need new ones put in — be sure you get new
approved replacement parts. If you do not,
the brakes might not work properly. For example,
if someone puts in brake linings that are wrong
for your vehicle, the balance between the front
and rear brakes can change — for the worse.
The braking performance you have come to expect
can change in many other ways if someone
puts in the wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 396for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.

Vehicle Storage
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from the battery. This will help keep the
battery from running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 432for tips on working
around a battery without getting hurt.
Jump Starting
If your vehicle’s battery has run down, you may
want to use another vehicle and some jumper
cables to start your vehicle. Be sure to use
the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode
or ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly,
some or all of these things can hurt you.
432

Notice:Ignoring these steps could result in
costly damage to your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.
Notice:If the other vehicle’s system is not a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
vehicles with 12-volt systems with negative
grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause a ground connection you do not
want. You would not 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 rmly on both vehicles
involved in the jump start procedure. Put an
automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake. If you have a
four-wheel-drive vehicle, be sure the transfer
case is not in NEUTRAL.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlets, if equipped. Turn off the radio and all
lamps that are not needed. This will avoid
sparks and help to save both batteries. And it
could save the radio!
433

4. Open both hoods and locate the batteries.
Find the positive (+) and negative (−)
terminals on each battery. Your vehicle has a
remote negative (−) jump starting terminal.
You should always use this remote terminal
instead of the terminal on the battery.
The remote negative (−) terminal is located
on the front engine lift bracket on vehicles
with the 4.2L L6 engine or the engine
accessory drive bracket for vehicles with
the 5.3L or 6.0L V8 engines, and is marked
GND (Ground). SeeEngine Compartment
Overview on page 396for more information
on location.
{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 ashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the battery
installed in your new vehicle. But if a
battery has ller caps, be sure the right
amount of uid is there. If it is low, add
water to take care of that rst. If you do not,
explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you accidentally
get it in your eyes or on your skin, ush the
place with water and get medical help
immediately.

{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
5. Check that the jumper cables do not 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 (+) or to a remote
positive (+) terminal if the vehicle has one.
Negative (−) will go to a heavy, unpainted
metal engine part or to a remote negative (−)
terminal if the vehicle has one. Do not
connect positive (+) to negative (−) or you will
get a short that would damage the battery
and maybe other parts too. And do not
connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.6. Connect the red
positive (+) cable to
the positive (+)
terminal of the dead
battery. Use a
remote positive (+)
terminal if the
vehicle has one.
7. Do not 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.
435

8. Now connect the black negative (−) cable to
the negative (−) terminal of the good battery.
Use a remote negative (−) terminal if the
vehicle has one.
Do not let the other end touch anything until
the next step. The other end of the
negative (−) cable does not go to the dead
battery. It goes to a heavy, unpainted
metal engine part or to the remote negative (−)
terminal on the vehicle with the dead battery.
Your vehicle has a remote negative (−)
terminal, marked GND, for this purpose.
The remote negative (−) terminal is located
on the front engine lift bracket for the
4.2L L6 engine, and on the accessory drive
bracket for the 5.3L or 6.0L V8 engines.
9. Connect the other end of the negative (−)
cable to the remote negative (−) terminal
on the vehicle with the dead battery.
10. Now start the vehicle with the good battery
and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries,
it probably needs service.

Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting
may occur and damage the vehicle. The repairs
would not be covered by your warranty. Always
connect and remove the jumper cables in the
correct order, making sure that the cables do
not touch each other or other metal.
A. Heavy, Unpainted Metal Engine Part or
Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and
Remote Negative (−) Terminals
C. Dead Battery or Remote Positive (+) TerminalTo disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 86.
Headlamps
The headlamp wiring is protected by four fuses.
An electrical overload will cause a lamp to go
on and off. If this happens, have your headlamp
wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, the wiper will stop
until the motor cools. If the overload is caused by
some electrical problem, be sure to get it xed.
Power Windows and Other
Power Options
Circuit breakers 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 xed
or goes away.
