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.
10. Connect the other end of the
negative ( ) cable to a heavy,

to the remote negative ( )

the dead battery.
11. Start the vehicle with the good
battery and run the engine for a
while.

the dead battery. If it will not
start after a few tries, it
probably needs service.

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
