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.
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.
Notice: If the jumper cables are removed too
quickly after starting the vehicle with the dead
battery, a momentary spike in voltage may occur,
damaging electrical components. The repairs would
not be covered by your warranty. Always allow
both vehicles involved in the jump start procedure
to run for at least one minute after starting the
vehicle with the dead battery, before removing the
jumper cables.
11. Try to start the vehicle that had the dead battery. If
it will not start after a few tries, it probably needs
service. If the vehicle does start, be sure to
allow both vehicles to run for at least one minute
before removing the jumper cables.
