GMC ENVOY XL 2004 Owner's Manual page 353

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 don't 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. Don't
connect positive (+) to negative ( ) or you'll get
a short that would damage the battery and maybe
other parts too. And don't 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.
