2005 Pontiac Grand Prix Owner ManualM

What Will You See After an
Airbag Inates?
After an airbag inates, it quickly deates, so quickly that
some people may not even realize the airbag inated.
Some components of the airbag module — the steering
wheel hub for the driver’s airbag, the instrument panel for
the right front passenger’s bag or the ceiling of your
vehicle near the side windows — will be hot for a short
time. The parts of the bag that come into contact with you
may be warm, but not too hot to touch. There will be
some smoke and dust coming from the vents in the
deated airbags. Airbag ination does not prevent the
driver from seeing or being able to steer the vehicle, nor
does it stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, 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 not get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.
In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation. Additional
windshield breakage may also occur from the right front
passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for your
airbag system. If you do not get them, the airbag
system will not be there to help protect you in another
crash. A new system will include airbag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
1-55

Your vehicle is equipped with a crash sensing and
diagnostic module which records information after a
crash. SeeVehicle Data Collection and Event Data
Recorders on page 7-10.
Let only qualied technicians work on your airbag
system. Improper service can mean that your airbag
system will not work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the side
impact airbag covering on the ceiling near the
side windows, the airbag may not work properly.
You may have to replace the airbag module in
the steering wheel, both the airbag module and the
instrument panel for the right front passenger’s
airbag, or side impact airbag module and ceiling
covering for the roof-mounted side impact airbag.
Do not open or break the airbag coverings.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
inate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-13.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are close
to an airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.

Remote Keyless Entry System
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.
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 modications to this system by other than
an authorized service facility could void authorization to
use this equipment.At times you may notice a decrease in range. This is
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 “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.

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.
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.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
®III uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III Operation
The vehicle is equipped
with PASS-Key®III
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®III is a passive
theft-deterrent system.
This means nothing special
needs to be done to arm
or disarm the system.
It works when the key is
inserted or removed
from the ignition.
PASS-Key III
®uses a transponder in the ignition key
that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the wrong
key has been inserted into the ignition, it shuts down the
vehicle’s starter and fuel systems. The starter will not
work and fuel will stop owing to the engine. If someone
tries to start the vehicle again with the wrong key, the
vehicle will not start. Anyone using a trial-and-error
method to start the vehicle will be discouraged to do so
because of the high number of electrical key codes.
2-19

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 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. SeeFuses
and Circuit Breakers on page 5-103. If the engine still
does not start with the other key, the vehicle needs
service. If the vehicle does start, the rst key may
be faulty. See your dealer who can service the
PASS-Key
®III to have a new key made. In an
emergency, contact Pontiac Roadside Assistance.
SeeRoadside Assistance Program on page 7-6for
more information.
It is possible for the PASS-Key
®III decoder to accept
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 programmed keys are
lost or do not operate, see your dealer or a locksmith
who can service PASS-Key
®III to have keys made
and programmed to the system.If the keys are lost or damaged, only a GM dealer can
service PASS-Key
®III to have new keys made. To
program additional keys, two driver’s keys are needed.
Canadian Owners:If you lose or damage your
keys, only a GM dealer can service PASS-Key
®III 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.
2-20

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 the SECURITY DISABLED DUE TO THEFT SYSTEM
warning message appears and stays on the DIC
while the vehicle is being driven, the engine will be able
to be restarted if it is turned off. Your PASS-Key
®III
system, however, is not working properly and must be
serviced by your dealer. The vehicle is not protected
by the PASS-Key
®III system at this time.
If the PASS-Key
®III key is lost or stolen, see your
dealer or a locksmith who can service PASS-Key®III
to have a new key made.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-40for more information.

Ignition Positions
The ignition switch is located on the instrument panel,
to the right of the steering column.
There are four different
positions. Insert the key
in the ignition and turn
it to the right for each
position.
9(OFF):This position locks the ignition, steering
wheel and transaxle. It is a theft-deterrent feature. This is
the only position from which the key can be removed.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.ACC (ACCESSORY):This position allows things like
the radio and windshield wipers to operate while
the engine is off.
R(RUN):This position is where the key returns to
after the vehicle is started. With the engine off, the
RUN position displays 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 for normal driving.
A continuous warning chime will sound and a KEY IN
IGNITION warning message will display on the
Driver Information Center (DIC) if the key is in the
ignition in OFF or ACC and the driver’s door is opened.
Retained Accessory Power (RAP)
If the vehicle has Retained Accessory Power (RAP),
certain features will continue to operate for up to
10 minutes after the ignition key is turned to OFF unless
a door is opened.
