PONTIAC GRAND PRIX 2003 Owners Manual

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. 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.
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.
6. 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.

7. Don't 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. Don't let the other end touch anything until the next
step. The other end
of the negative (-) cable doesn't
go to the dead battery. It goes to a heavy, unpainted
metal part or to
a remote negative (c) terminal on the
vehicle with the dead battery.
8. 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. 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.
5-57

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 won’t start after a few tries, it probably needs
service.
Notice: Damage to your vehicle may result from
electrical shorting
if jumper cables are removed
incorrectly. To prevent electrical shorting, take care
that the cables don’t touch each other or any
other metal. The repairs wouldn’t be covered by
your warranty.

Headlamp Aiming
The aim of your vehicle’s headlamps can be adjusted
by using aim tips located on the outer surface of
the
lens. The aim has been pre-set at the factory and
should need
no further adjustment.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the
low beam
may be necessary
if it is difficult to see lane markers
(for horizontal aim), or
if oncoming drivers flash
their high beams at you (for vertical aim). If you believe
your headlamps need to be re-aimed, it
is recommended
that you take your vehicle to the dealer for assistance.
