6. Connect the red positive (+) cable to the
positive (+) terminal location of the vehicle
with the dead battery. Use a remote
positive (+) terminal if the vehicle has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal location of the
vehicle with the good battery. Use a remote
positive (+) terminal if the vehicle has one.
8. Now connect the black negative ( ) cable to
the negative ( ) terminal location of the
vehicle with the good battery. 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.

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 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 your 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.
