6. Do not let the other end
of the red positive (+) cable
touch metal. Connect it to
the positive (+) terminal of the
good battery (B). Use a remote
positive (+) terminal if the vehicle
has one.
7. Connect one end of the
black negative ( ) cable to
the negative ( ) terminal of
the good battery (C). Use a
remote negative ( ) terminal
if the vehicle has one.
Do not let the other end touch
anything until the next step.
The other end of the negative ( )
cable does not 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.
8. Connect the other end of the
black negative ( ) cable to an
unpainted heavy metal engine
part (D) away from the dead
battery, but not near engine
parts that move.
9. Start the engine in the vehicle
with the good battery and run
the engine at idle speed for at
least four minutes.
10. Try to start the vehicle that
had the dead battery. If it will
not start after a few tries,
it probably needs service.
Notice: If the jumper cables
are connected or removed in
the wrong order, electrical
shorting may occur and damage
the vehicle. The repairs would
not be covered by the vehicle
warranty. Always connect and
remove the jumper cables in the
correct order, making sure that
the cables do not touch each
other or other metal.
