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 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 (+) 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.
Don't connect the positive (+) to negative (
-) or
you'll get a short that would damage the battery and
maybe other parts too. And don't 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.

5-7
7. Don't 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.
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 engine part or to the 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.10. Now start the vehicle with the good battery and run
the engine for one or two minutes. If your vehicle
has the high idle option, use it.
11. Try to start the vehicle with 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.

Battery
Your new vehicle comes with one or more maintenance
free ACDelco
batteries. When it's time for a new
battery, be sure it has the replacement number shown
on the original battery's label. We recommend an
ACDelco battery.
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. (If your vehicle has more than one battery, be
sure to remove the negative (
-) battery cable from
each battery.)
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.
When you are ready to use the vehicle again, refer to the
engine starting procedure in the Index.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
