2004 Pontiac Grand Prix Owner ManualM

{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.)

Your keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.

normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement is
necessary. See ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or
a quali®ed technician for service.

Arming with the Remote Keyless
Entry Transmitter
The alarm system will arm when you use the remote
keyless entry transmitter to lock the doors after the key
is removed from the ignition. The red light will turn
on to let you know the system is arming. After all doors
are closed and locked, the red light will begin ¯ashing
at a very slow rate to let you know the system is armed.
Arming Con®rmation
If the remote unlock con®rmation is on, the headlamps
will ¯ash brie¯y to let you know when the alarm system
has armed. See
DIC Controls and Displays on page 3-45for more information on personal programming.
Disarming with the Remote Keyless
Entry Transmitter
The alarm system will disarm when you use your remote
keyless entry transmitter to unlock the doors. The red
light will go off to let you know the system is disarmed.
Disarming with Your Key
The alarm system will disarm when you use the key to
unlock the doors. The red light will stop ¯ashing when the
system is disarmed. If you would like the key to disarm
the alarm system, see
DIC Controls and Displays on
page 3-45for more information on personal programming.
PASS-KeyžIII
Your PASS-KeyžIII system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
žIII uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
2-15

PASS-KeyžIII Operation
Your vehicle is equipped
with PASS-KeyžIII
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
žIII is a passive
theft-deterrent system. This
means you don't have to do
anything special to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
When the PASS-Key
žIII system senses that someone
is using the wrong key, it shuts down the vehicle's
starter and fuel systems. The starter will not work and
fuel will stop ¯owing to the engine. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED DUE TO THEFT
SYSTEM warning message on the Driver's Information
Center (DIC) comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time, you
may also want to check the fuse. See
Fuses and Circuit
Breakers on page 5-99. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the ®rst key may be faulty. See your
dealer who can service the PASS-Key
žIII to have a new
key made. In an emergency, contact Pontiac Roadside
Assistance. See
Roadside Assistance Program on
page 7-6for more information.
It is possible for the PASS-Key
žIII decoder to ªlearnº
the transponder value of a new or replacement key.
Up to 10 additional keys may be programmed for
the vehicle. The following procedure is for programming
additional keys only. If all the currently programmed
keys are lost or do not operate, you must see your
dealer or a locksmith who can service PASS-Key
žIII
to have keys made and programmed to the system.
2-16

Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-KeyžIII to
have new keys made. To program additional keys,
you will need two current driver's keys. You must add a
step to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver's key.
Then continue with Step 3.
To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master key in the ignition and start
the engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within ®ve seconds of removing the original key.5. The SECURITY DISABLED DUE TO THEFT
SYSTEM warning message on the DIC will turn off,
once the key has been programmed. It may not
be apparent that the SECURITY DISABLED DUE
TO THEFT SYSTEM warning message went on due
to how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If you are ever driving and the SECURITY DISABLED
DUE TO THEFT SYSTEM warning message on the DIC
comes on and stays on, you will be able to restart
your engine if you turn it off. Your PASS-Key
žIII system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
žIII system at this time.
If you lose or damage your PASS-Key
žIII key, see your
dealer or a locksmith who can service PASS-KeyžIII
to have a new key made.
2-17

Notice:If your key seems stuck in OFF and you
can't turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the key
hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.
ACC (ACCESSORY):This position lets you use things
like the radio and windshield wipers while the engine
is off.
R(RUN):This position is where the key returns to
after you start the vehicle. With the engine off, you can
use RUN to display some of the warning and indicator
lights.
/(START):This position starts the engine. Let go of
the key when the engine starts. The key will return
to the RUN position.
A continuous warning chime will sound and a KEY IN
IGNITION warning message will display on the DIC
if the key is in the ignition in the OFF or ACCESSORY
positions and the driver's door is opened.
Retained Accessory Power (RAP)
With Retained Accessory Power (RAP), the power
windows, audio system and sunroof will continue to
work up to 10 minutes after the ignition key is turned
to OFF and none of the doors are opened.
Starting Your Engine
1. Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position ± that's
a safety feature. To restart while you're already
moving, use NEUTRAL (N) only.
Notice:Don't try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the transaxle.
Shift to PARK (P) only when your vehicle is stopped.
2. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
