PONTIAC GRAND PRIX 2004 Owners Manual

{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.
{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
¯ashlight if you need more light.
Be sure the battery has enough water. You don't
need to add water to the ACDelco
žbattery
installed in your new vehicle. But if a battery
has ®ller caps, be sure the right amount of ¯uid
is there. If it is low, add water to take care of
that ®rst. If you don't, explosive gas could be
present.
Battery ¯uid contains acid that can burn you.
Don't get it on you. If you accidentally get it in
your eyes or on your skin, ¯ush the place with
water and get medical help immediately.

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 (+) 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.
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.
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.
5-52

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.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.
Don't let the other end touch anything until the next
step. The other end of the negative (-) cable
doesn'tgo to the dead battery. It goes to a heavy, unpainted
metal part or to a remote negative (±) terminal on the
vehicle with the dead battery.
5-53

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.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 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.

A. Heavy, Unpainted Metal Engine Part
B. Good Battery or Remote Positive (+) Terminal
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 remote positive (+) terminal 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
If the vehicle is damaged in an accident, 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 you take the vehicle to your
dealer for service if the headlamps need to be re-aimed.
However, it is possible for you to re-aim the headlamps
as described in the following procedure.The vehicle should be properly prepared as follows:·The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other ¯at
surface.
·The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other ¯at surface.
·The vehicle should be placed so it is perpendicular
to the wall or other ¯at surface.
·The vehicle should not have any snow, ice or mud
attached to it.
·The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
·The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg) on
the driver's seat.
·Tires should be properly in¯ated.
5-56

Headlamp aiming is done with the vehicle's low-beam
lamps. The high-beam lamps will be correctly aimed
if the low-beam lamps are aimed properly.
The vertical headlamp aiming screws are under the
hood near the headlamps.
Adjustment screws can be turned with an E8 Torx
ž
socket or T15 Torxžscrewdriver.
Headlamp Vertical Aiming
1. Find the aim dot on the lens of the low beam lamp.
2. Measure the distance from the ground to the aim
dot on the lamp. Record the distance.
5-57

3. At the wall or other ¯at surface, measure from the
ground upward the recorded distance from Step 2
and draw or tape a horizontal line the width of
the vehicle.4. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being aimed. This should allow only
the beam of light from the headlamp being
aimed to be seen on the ¯at surface.
Notice:Do not cover a headlamp to improve beam
cut-off when aiming. Covering a headlamp may
cause excessive heat build-up which may cause
damage to the headlamp.
5-58

5. Turn the vertical aiming screw until the headlamp
beam is aimed to the horizontal tape line. The top
edge of the cut-off should be positioned at the
bottom edge of the horizontal tape line.
6. Repeat steps 4 and 5 for the opposite headlamp.
