PONTIAC GRAND PRIX 2004 Repair Manual

{CAUTION:
When an air bag in¯ates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can't get out of the vehicle after an air bag
in¯ates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment,
you should seek medical attention.
In many crashes severe enough to in¯ate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
·Air bags are designed to in¯ate only once. After an
air bag in¯ates, you'll need some new parts for
your air bag system. If you don't get them, the air
bag system won't be there to help protect you
in another crash. A new system will include air bagmodules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
·Your vehicle is equipped with a crash sensing and
diagnostic module, which records information
about the air bag system. The module records
information about the readiness of the system,
when the system commands air bag in¯ation and
driver's safety belt usage at deployment.
·Let only quali®ed technicians work on your air bag
system. Improper service can mean that your air
bag system won't work properly. See your dealer for
service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, or the side
impact air bag covering on the ceiling near the
side windows, the bag may not work properly.
You may have to replace the air bag module in the
steering wheel, both the air bag module and the
instrument panel for the right front passenger's air
bag, or side impact air bag module and ceiling
covering for the roof-mounted side impact air bag.
Do not open or break the air bag coverings.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
in¯ate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the air bag system.
To purchase a service manual, see
Service Publications
Ordering Information on page 7-10.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an air bag can still in¯ate during improper
service. You can be injured if you are close
to an air bag when it in¯ates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is quali®ed to do so.
The air bag system does not need regular maintenance.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.If you've had a crash, do you need new belts or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system wasn't being used at the time of
the collision.
If an air bag in¯ates, you'll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.
If the frontal air bags in¯ate, you'll also need to replace
the driver's and right front passenger's safety belt
buckle assembly. Be sure to do so. Then the new buckle
assembly will be there to help protect you in a collision.

the content theft deterrent system. See
Content
Theft-Deterrent on page 2-14for more details.
L(Remote Alarm):Press the button with the horn
symbol to make the headlamps ¯ash and the horn
sound. This lets you attract attention, if needed.
V(Open Trunk):Press this button to release the
trunk lid. The transaxle must be in PARK (P) for
this feature to operate.
Your vehicle may have Remote Lock/Unlock
Con®rmation. This feature provides feedback
that a command has been received by the vehicle.
The headlamps will ¯ash and the horn may sound
brie¯y. See
DIC Controls and Displays on page 3-45for programming information.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
2-5

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range. If you have to get close
to your vehicle before the transmitter works, it's probably
time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery do the following:
1. Insert a ¯at object like a thin coin into the notch
located on the front of the transmitter, below the
open trunk button, and pry it apart.
2. Gently slide the battery out of the transmitter.
Do not use a metal object to remove the battery.
3. Slide the new battery into the transmitter. Use a
type CR2032 battery, or equivalent type.
4. Snap the transmitter back together, making sure the
halves are secured tightly, so water will not get in.
5. Test the operation of the transmitter with the
vehicle. If the transmitter does not work,
resynchronize the transmitter.
Resynchronization
If the functions on the remote keyless entry transmitter
do not work, or, if only the remote alarm works, after
the battery is replaced, then the transmitter needs to be
resynchronized to the receiver. Do this by pressing
and holding the LOCK and UNLOCK buttons on
the transmitter at the same time for about eight seconds.
You must be within range of the vehicle.
Once the transmitter has been resynchronized, the
horn will sound and the exterior lamps will ¯ash once.
The system should now operate properly.
