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.
Your vehicle's remote negative ( ) terminal is
marked GND.
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 awhile.
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.
