Cadillac 2008 DTS - Manual (Page 337)

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 remote
positive (+) terminal location on the vehicle with
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 location of the vehicle
with the good battery. Use a remote positive (+)
terminal if the vehicle has one.
8. Now connect the black negative ( − ) cable to the
negative ( − ) terminal location of the vehicle with
the good battery. Use a remote negative ( − )
terminal if the vehicle has one.
Do not let the other end of the cable 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 to
the negative (
−
) terminal location on the vehicle
with the dead battery. Your vehicle has a remote
negative (
−
) terminal marked GND (
−
).
10. Now start the vehicle with the good battery and
run the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably needs
service.
