2003 CHEVROLET AVALANCHE battery

{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
don't need to add water to the ACDelco
ž
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 don't, explosive
gas could be present.
Battery ¯uid contains acid that can burn you.
Don't 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.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 positive (+) to negative (-) or you'll
get a short that would damage the battery and
maybe other parts too.
{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.

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. 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. Your vehicle's
remote negative (-)
terminal is marked
GND.
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 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.
10. Now start the vehicle with the good battery and run
the engine for awhile.
11. Try to start the vehicle that had the dead battery. If it
won't start after a few tries, it probably needs service.
