Hummer 2007 H3 - Manual (Page 355)

{ CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
5. Check that the jumper cables do not have
loose or missing insulation. If they do, you
could get a shock. The vehicles could
be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+)
will go to positive (+) or to a remote positive (+)
terminal if the vehicle has one. Negative (
−
)
will go to a heavy, unpainted metal engine part
or to a remote negative (
−
) terminal if the
vehicle has one.
Do not connect positive (+) to negative (
−
) or
you will get a short that would damage
the battery and maybe other parts too. And do
not connect the negative (
−
) cable to the
negative (
−
) terminal on the dead battery
because this can cause sparks.
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.
