Cadillac 2007 XLR - Manual (Page 406)

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.
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.
