Chevrolet 2007 Express 2007 Express Owner's Manual page 329

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.
