Jump Starting
If your battery has run down, you may want to
use another vehicle and some jumper cables to start
your vehicle. But please 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 don't 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 wouldn't be covered by
your warranty.
The ACDelco battery in your vehicle has a
built
-in hydrometer. Do not charge, test or jump
start the battery if the hydrometer looks clear
or light yellow. Replace the battery when there
is a clear or light yellow hydrometer and a
cranking complaint.
Trying to start your vehicle by pushing or pulling
it won't 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 system isn't a 12-volt system with a
negative ground, both vehicles can be damaged.

5-4
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 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 (N).
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets (if equipped). Turn
off the radio and all lamps that aren't needed. This
will avoid sparks and help to save both batteries.
And it could save your radio!
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 and is marked ªGND.º See
ªEngine Compartment Overviewº in the Index for
more information on location.

5-7
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 won't start after a few tries, it probably
needs service.
NOTICE:
Damage to your vehicle may result from
electrical shorting if jumper cables are removed
incorrectly. To prevent electrical shorting, take
care that they don't touch each other or any
other metal. The repairs wouldn't be covered by
your warranty.
Jumper Cable Removal
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 (+) Terminal

Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery, get
one that has the replacement number shown on the
original battery's label. We recommend an ACDelco
battery. See ªEngine Compartment Overviewº in the
Index for 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'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.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº 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 ªTheft
-Deterrent
Featureº in the Index.
Bulb Replacement
For the type of bulbs, see ªReplacement Bulbsº in
the Index.
For any bulb changing procedure not listed in this
section, contact your dealer.
