{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.
9. Connect the other end of the
negative (−) cable at least
18 inches (45 cm) away from
the dead battery, but not
near engine parts that move.
The electrical connection is just
as good there, and the chance
of sparks getting back to the
battery is much less.
Your vehicle has a remote
negative (−) terminal, marked
GND (Ground), for this purpose.

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.
Notice:If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not
be covered by your warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the cables
do not touch each other or
other metal.A. Heavy, Unpainted Metal Engine

3. Disconnect the red positive (+)
