6. 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.
Notice:If you connect a negative cable to the
Engine Control Module (ECM), ECM mounting
bracket or any cables that attach to the ECM
bracket, you may damage the ECM. Attach the
negative cable to a heavy, unpainted metal engine
part, other than the ECM, ECM bracket or cables
attached to the ECM bracket.
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.3.8L V6 Engine

7. Connect the red positive (+) cable to the positive (+)
terminal location on the vehicle with the dead battery.
Use a remote positive (+) terminal if the vehicle
has one.
8. Do not let the other end touch metal. Connect it to
the positive (+) terminal location on the vehicle with
the good battery. Use a remote positive (+) terminal if
the vehicle has one.9. Now connect the black negative (−) cable to the
negative (−) terminal location on the vehicle with
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.
10. 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.
11. Now start the vehicle with the good battery and run
the engine for a while.
12. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably needs
service. 5.3L Engine

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 Part or Remote
Negative (−) Terminal
B. Good Battery or Remote Positive (+) and Remote
Negative (−) Terminals
C. Dead Battery or Remote Positive (+) TerminalTo disconnect the jumper cables from both vehicles, do
the following:
1. Disconnect the black negative (−) cable from the
vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from the
vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the other
vehicle.
5. Return the fuse block cover to its original position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may
be necessary.
If oncoming vehicles ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to
be re-aimed. It is possible however, to re-aim the
headlamps as described. Jumper Cable Removal
