GMC 2001 Envoy - Manual (Page 279)

5-5
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 (+) and negative (
- ) will go to a heavy,
unpainted metal engine part. 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 (
- ) to negative ( - ).
6. Connect the red
positive (+) cable to
the positive (+) terminal
of the vehicle with the
dead battery.
7. Don’t let the other
end touch metal.
Connect it to the
positive (+) terminal
of the good battery.
