2006 Buick Terraza Owner ManualM

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.
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 an
airbag system will not work properly. See your
dealer for service.
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 3-39.
The passenger sensing system will turn off the right
front passenger’s frontal airbag and side impact airbag
(if equipped) under certain conditions. The driver’s
airbags or the second row side imact airbags (if
equipped) are not part of the passenger sensing system.United States
Canada
1-66

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 3-38for more on this, including
important safety information.
1-69

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 1-71for 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 7-15.
{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.
1-70

Any new PASS-Key®III key must be programmed
before it will start your vehicle. SeePASS-Key®III on
page 2-30for 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 7-6for 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 2-45
for more information.

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.

2-4

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.
Remote Keyless Entry System
Operation
You can lock and unlock the vehicle’s doors and the
liftgate using the remote keyless entry transmitter
supplied with your vehicle.
The remote keyless entry
transmitter shown here is
for a vehicle equipped
with the remote vehicle
start feature and dual
power sliding doors.
The remote keyless entry transmitter supplied with your
vehicle will only contain the buttons specic to your
vehicle’s factory installed remote system features.
2-5

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.
2-24

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 3-72.
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. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
2-30

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 5-96.
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.

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 constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
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 4-39for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
The key can be turned to one of four positions while in
the ignition switch.
A (LOCK):This is the only position from which you can
remove the key. This position locks your ignition and
transaxle.
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.
