Chevrolet 2003 Monte Carlo Owner's Manual page 286

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 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.
