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. 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.

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 (-) cabledoesn'tgo 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 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 the cables don't touch each other or any
other metal. The repairs wouldn't be covered by
your warranty.

When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. SeePart C: Periodic
MaintenanceInspections on page 6-12.
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 ®ller plug hole,
you'll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the ®ller plug hole.
What to Use
To add lubricant when the level is low, use
SAE 75W±90 Synthetic Gear Lubricant (GM Part
No. 12378261) or equivalent meeting GM
Speci®cation 9986115. To completely re®ll after draining,
add 4 ounces (118 ml) of Limited-Slip Differential
Lubricant Additive (GM Part No. 1052358) or equivalent.
Then ®ll to the bottom of the ®ller plug hole with the
Synthetic Gear Lubricant.

twice a year for wear or cracking. See ªWiper Blade

removed in different ways. For the proper type and
length, see

assembly every six months.

blade assembly. Accidental bumping can cause the
arm to fall back and strike the windshield.
To remove the wiper blade assembly, do the following:
