2005 Buick Terraza Owner ManualM

What Will You See After an Airbag
Inates?
After the airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module will be
hot for a short time. These components include the
steering wheel hub for the driver’s frontal airbag and the
instrument panel for the right front passenger’s frontal
airbag. For vehicles with side impact airbags, the side of
the seatback closest to the driver’s and/or right front
passenger’s door will be hot. 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
cannot 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.
1-61

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 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that an 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 airbag
covering on the driver’s and right front passenger’s
seatback, 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 both the airbag module and seatback
for the driver’s and right front passenger’s
side impact airbag. Do not open or break the
airbag coverings.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key to
RUN or START. The words ON and OFF or the symbol
for on and off, will be visible during the system check.
When the system check is complete, either the word ON
or the word OFF, or the symbol for on or the symbol
for off will be visible. SeePassenger Airbag Status
Indicator on page 3-35.
Passenger Airbag Status Indicator – United States
Passenger Airbag Status Indicator – Canada
1-62

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat.
If this happens, turn the vehicle off and ask the person
to place the seatback in the fully upright position,
then sit upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended. Restart
the vehicle and have the person remain in this position
for about two minutes. This will allow the system to
detect that person and then enable the passenger’s
airbag or airbags.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-34for more on this, including
important safety information.
1-65

Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or
other aftermarket equipment if your vehicle has
the passenger sensing system. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on page 1-67for
more information about modications that can affect
how the system operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat cushion
and seatback may interfere with the proper
operation of the passenger sensing system.
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. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-11.
{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.
1-66

Any new PASS-Key®III key must be programmed
before it will start your vehicle. SeePASS-Key®III on
page 2-28for more information on programming
your new key.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle, see
Roadside Assistance Program on page 7-5for more
information.
If your vehicle is equipped with the OnStar
®system with
an active subscription and you lock your keys inside
the vehicle, OnStar
®may be able to send a command to
unlock your vehicle. SeeOnStar®System on page 2-42
for more information.
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.
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.
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

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.
2-4

If any of these conditions occur, the power sliding door
may need to be reset. If your vehicle has the dual
power sliding doors, both doors will have to be reset.
To reset a door, do the following:
1. Check to be sure the power sliding door is unlocked
and securely closed.
2. Turn the ignition to LOCK.
3. If the power sliding door overhead console switch is
in the override (deactivation) position, return to the
activation position.
4. Open the sliding door using the remote keyless
entry transmitter, overhead console switch, or
passenger switch. Allow the door to travel
fully open.
If the door does not travel to the fully open position,
press the overhead console switch to the override
(deactivation) position and slide the door fully open and
closed. Check for foreign objects in the tracks. Repeat
the procedure starting with Step 1. If the door resists
travel to the fully open position, see your dealer
for service.Liftgate
To unlock or lock the liftgate from the outside, use the
remote keyless entry transmitter. For more information,
seeRemote Keyless Entry System Operation on
page 2-5.
You can also use the power door lock switch to lock
and unlock the liftgate.
Open the liftgate using the handle located above the
license plate. Once slightly opened, the liftgate will rise
by itself. Lamps in the rear of the vehicle will come
on, illuminating the rear cargo area.
Notice:If you open the liftgate without checking
for overhead obstructions such as a garage
door, you could break the liftgate glass. Always
check to make sure the area above the liftgate
is clear before opening it.
2-22

Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the driver’s door. The security light will
stop ashing to let you know the system is no longer
armed. If you would like your key not to disarm the alarm
system, seeDIC Vehicle Personalization (Uplevel
Only) on page 3-68.
PASS-Key®III
Your PASS-Key®III 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.
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
Your vehicle is equipped
with the PASS-Key®III
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®III is a passive
theft deterrent system.
This means you do
not have to do anything
different to arm or disarm
the system. It works
when you insert or remove
the key from the ignition.
When the PASS-Key
®III 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 being delivered to the engine.
2-28

Anyone using a trial-and-error method to start the
vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security message
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 instrument panel PASS
KEY fuse. 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 or
a locksmith who can service the PASS-Key
®III to
have a new key made. SeeFuses and Circuit Breakers
on page 5-87.
It is possible for the PASS-Key
®III decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
This procedure is for learning 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
®III to have keys made
and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III to get a new key blank that is cut
exactly as the ignition key that operates the system.To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder 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 10 seconds of removing the previous key.
5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly
the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message
comes on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, see your
dealer or a locksmith who can service PASS-Key®III
to have a new key made.
2-29

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
none of this works, then your vehicle needs service.
B (ACCESSORY):This is the position in which you can
operate the electrical accessories, such as the radio.
C (RUN):This is the position to which the switch returns
after the engine is started and the ignition key is
released. This is the position for driving. Even while the
engine is not running, RUN can be used to operate
your electrical accessories and to display some
instrument panel warning lights.
D (START):This position starts the engine. When the
engine starts, release the ignition key. The switch
will return to RUN for driving.
Retained Accessory Power (RAP)
With RAP, your power windows and the audio system
will continue to work for up to 10 minutes after the
engine is turned off or until either door is opened. If a
door is opened, the power windows and audio system
will shut off.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. 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 warms up.
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.
2. If the engine does not start in 10 seconds, push the
accelerator pedal about one-quarter of the way down
while you turn the key to START. Do this until the
engine starts. As soon as it does, let go of the key.
