Cadillac CTS - Manual (Page 381)

6. Connect the red positive (+) cable to the
positive (+) terminal of the dead battery.
Use a remote positive (+) terminal if
the vehicle has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal of the good
battery. Use a remote positive (+) terminal if
the vehicle has one.
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.
Use a remote negative (
−
) terminal if the
vehicle has one. Your vehicle’s remote
negative (
−
) ground location is for this purpose.
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.
