2004 PONTIAC GRAND PRIX ECU

{CAUTION:
Both frontal and side impact air bags in¯ate
with great force, faster than the blink of an
eye. If you're too close to an in¯ating air bag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for air bag in¯ation before
and during a crash. Always wear your safety
belt even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Occupants
should not lean on or sleep against the door.
{CAUTION:
Anyone who is up against, or very close to,
any air bag when it in¯ates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle's safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called ªOlder
Childrenº or ªInfants and Young Children.º

The side impact air bag for the right front passenger
and the person seated directly behind that passenger is
in the ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not in¯ate properly or it
might force the object into that person causing
severe injury or even death. The path of an
in¯ating air bag must be kept clear. Don't put
anything between an occupant and an air bag,
and don't attach or put anything on the
steering wheel hub or on or near any other air
bag covering. And, because your vehicle has
side impact air bags, never secure anything to
the roof of your vehicle by routing the rope or
tiedown through any door or window opening.
If you do, the path of an in¯ating side impact
air bag will be blocked. The path of an in¯ating
air bag must be kept clear.

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.

Trunk Assist Handle
The trunk assist handle is
located inside the trunk lid
toward the driver's side
of the vehicle.
Notice:The trunk assist handle is not designed to
be used to tie down the trunk lid or as an anchor
point when securing items in the trunk. Improper
use of the trunk assist handle could damage it.
Pull down on the handle to lower the trunk lid. Then
close the trunk with your other hand. If the trunk is not
properly closed, the AJAR message, along with a
trunk ajar graphic will appear on the DIC. See

information.
Emergency Trunk Release Handle
Notice:The emergency trunk release handle is not
designed to be used to tie down the trunk lid or as
an anchor point when securing items in the trunk.
Improper use of the emergency trunk release handle
could damage it.
There is a glow-in-the-dark emergency trunk release
handle located on the latch inside the trunk lid. This
handle will glow following exposure to light. Pull the
release handle to open the trunk from the inside.

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.

Assist Handles
The vehicle has lighted assist handles located above
the rear doors. They can be used to help passengers
enter and exit the vehicle.
The lamps on the handles will come on automatically
when a door is opened and turn off when the door
is closed. The lamps can be manually turned on or off
if there are grooves on the lens of the lamp. Press
the grooved side of the lens to turn the lamp on or off.
Convenience Net
The vehicle is equipped with a convenience net in the
trunk that covers the passenger's side wheel well.
There may also be a convenience net attached to the
backside walls of the trunk. This net can be used as an
``envelope'' to hold items inside it, or, it can be pulled over
items to secure them. If used as an envelope, put small
loads like grocery bags inside the net. This can help items
from falling over during sharp turns or quick starts and
stops. To use this net to cover items in the trunk, attach
two corners of the net to the two loops located at the
bottom of the rear seatback. When not using the net,
hook the net to the tabs securing it to the trunk wall.
Other Storage Areas
The vehicle also has a trunk storage compartment. It is
located on the passenger's side of the trunk, above the
wheel well. It may lock. To access the storage area,
lift up on the handle of the compartment cover and pull.
