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 the remote negative ( ) terminal on
the vehicle with the dead battery. Your vehicle
has a remote negative ( ) terminal, marked
GND, for this purpose.
4.2L L6 Engine
The remote negative ( ) terminal is located on
the front engine lift bracket for the 4.2L L6
engine, and on the accessory drive bracket for
the 5.3L V8 engine.

9. Connect the other end of the negative ( )
cable to the remote negative ( ) terminal
on the vehicle with the dead battery.
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.
