Jump Starting
If your 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.
{WARNING:
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: If you try to start your vehicle by pushing or
pulling it, you could damage your vehicle. Do not
push or pull your vehicle to start it; instead, use the
jump starting procedure in this manual to start your
vehicle when the battery has run down.
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 firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in Neutral before setting the parking brakes.
Notice: If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the
cigarette lighter or the accessory power outlet.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help save
both batteries. And it could save the radio!

4. Open the hoods and locate the positive (+) and negative (−) terminal locations on each vehicle.
6.2 L LS3 shown, 7.0 L LS7 and 6.2 L LS9 similar
Your vehicle has a remote positive (+) terminal (A)
and a remote negative (−) terminal (B), as shown in
the illustration, which should be used to jump start
your vehicle. The remote positive (+) terminal (A) can be
accessed by opening the cover of the engine
compartment fuse block.
The remote negative (−) terminal (B) is located
underneath the engine cover, below the engine oil
fill cap.
See
Engine Compartment Overview
on page 6‑14for the location of the engine compartment fuse
block and engine oil fill cap.
You will not need to access the battery for jump
starting. The remote terminals are for that purpose.
{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
6-51

{WARNING:
Using an open flame 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 do not
need to add water to the battery installed in your
new 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 do not,
explosive gas could be present.
Battery fluid contains acid that can burn you.
Do not 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.
{WARNING:
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.
6-52

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.
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 a remote
negative (−) terminal on the vehicle with the dead
battery. 9. Connect the other end of the negative (−) 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,
and the chance of sparks getting back to the
battery is much less.
Your vehicle has a remote negative (−) terminal for
this purpose.
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.
6-53

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 the vehicle 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.
Jumper Cable Removal
A. Heavy, Unpainted Metal Engine Part or Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and Negative (−) Terminals
C. Dead Battery or Remote Positive (+) Terminal To 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.
5. Return the engine fuse block cover to its original position.
6. You may also need to initialize the power windows. See “Power Window Initialize” underPower
Windows
on page 3‑17for more information.

Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear axle fluid
unless you suspect there is a leak or you hear an
unusual noise. A fluid loss could indicate a problem.
Have it inspected and repaired.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface. If the level is below the bottom of the filler plug hole,
you will need to add some lubricant. Add enough
lubricant to raise the level to the bottom of the filler
plug hole.
What to Use
To add lubricant when the level is low, use Dexron LS
Gear Oil 75W-90 (GM Part No. US. 88862624, in
Canada 88862625) meeting GM Specification 9986290.
To completely refill after draining, see
Recommended
Fluids and Lubricants
on page 7‑10. Then fill to the
bottom of the filler plug hole with the Synthetic Gear
Lubricant.
Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in a crash, the
headlamp aim may be affected. Aim adjustment to the
low-beam headlamps may be necessary if oncoming
drivers flash their high-beam headlamps at you (for
vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your dealer/
retailer for service.

Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 6‑58.
For any bulb changing procedure not listed in this
section, contact your dealer/retailer.
High Intensity Discharge (HID)
Lighting
{WARNING:
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 seriously injured. Have your dealer/
retailer or a qualified technician service them.
The vehicle may have HID headlamps. After an HID
headlamp bulb has been replaced, you may notice
that the beam is a slightly different shade than it was
originally. This is normal.
Halogen Bulbs
{WARNING:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
