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 GM brake parts. When you replace parts
of your braking system — for example, when your
brake linings wear down and you need new ones
put in — be sure you get new approved GM
replacement parts. If you do not, 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 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 480for 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
your 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 521for tips on working
around a battery without getting hurt.
520

Jump Starting
If your vehicle’s battery (or batteries) 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.
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. If you have a vehicle with a diesel engine
with two batteries (or more), you should
know before you begin that, especially in cold
weather, you may not be able to get enough
power from a single battery in another vehicle
to start your diesel engine.
If your vehicle has more than one battery, use
the battery that is closer to the starter — this
will reduce electrical resistance.
521

5. Open the hoods and locate the positive (+)
and negative (−) terminal locations of the
other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−)
jump starting terminal. You should always
use these remote terminals instead of
the terminals on the battery.
The remote positive (+) terminal is located
behind a red plastic cover, near the engine
accessory drive bracket, if your vehicle
has one. To uncover the remote positive (+)
terminal, open the red plastic cover.
The remote negative (−) terminal is located
on the engine drive bracket on all V8 and
diesel engines, and on the thermostat housing
on the 8.1L engine. On V8 engines it is
marked GND (Ground).
On V6 engines the remote negative (−)
terminal is located on a tab attached to the
engine accessory drive bracket where it
is marked GND (Ground).
SeeEngine Compartment Overview on
page 480for more information on the location
of the remote positive (+) and remote
negative (−) terminals.
{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.
523

{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
6. 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 a remote positive
terminal (+) if the vehicle has one. Negative (−)
will go to a heavy, unpainted metal engine
part or 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.
On vehicles that have dual batteries, make all
battery connections to the remote positive (+)
and remote negative (−) terminals.
7. Connect the red
positive (+) cable
to the positive (+)
terminal of the
vehicle with the
dead battery. Use a
remote positive (+)
terminal if the vehicle
has one.
524

8. 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.
9. Now connect the black negative (−) cable to
the negative (−) terminal of the good battery.
Use a remote negative (−) terminal if the
vehicle has one. The vehicle’s remote
negative (–) terminal is marked GND.
10. 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 of the
vehicle with the dead battery, or to a remote
negative (–) terminal if the vehicle has one.11. Connect the
other end of the
negative (−) cable
to the remote
negative (−) terminal,
marked GND, on the
vehicle with the dead
battery.
SeeEngine Compartment Overview on
page 480for the location of your vehicle’s
remote negative (−) terminal.
12. Now start the vehicle with the good battery
and run the engine for a while.
13. 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 bad 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.
5. Return the remote positive (+) terminal cover,
if your vehicle has one, to its original position.
