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 a remote
negative (-) terminal on the vehicle with the dead
battery.
9. Connect the other end of the negative (-) cable to
the negative (-) terminal of the dead battery or
to a remote negative (-) terminal if the vehicle
has one.
10. Now start the vehicle with the good battery and run
the engine for a while.
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 the cables don't touch each other or any
other metal. The repairs wouldn't be covered by
your warranty.
