GMC 2009 Acadia - Manual (Page 319)

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.
Your vehicle has a remote
negative (
− ) terminal for this
purpose.
