belt BUICK TERRAZA 2006 Service Manual

{CAUTION:
Both frontal and side impact airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt even with frontal airbags. 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 airbag when it inates can be seriously
injured or killed. Airbags 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 airbag
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,
seeOlder Children on page 1-34orInfants and
Young Children on page 1-37.

Your vehicle may or may not have a side impact airbag.
SeeAirbag System on page 1-57. Side impact airbags
are intended to inate in moderate to severe side
crashes. A side impact airbag will inate if the crash
severity is above the system’s designed “threshold
level.” The threshold level can vary with specic vehicle
design. Side impact airbags are not intended to
inate in frontal or near-frontal impacts, rollovers or rear
impacts. A side impact airbag is intended to deploy
on the side of the vehicle that is struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For side impact
airbags, ination is determined by the location and
severity of the impact.What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The sensing
system triggers a release of gas from the inator, which
inates the airbag. The inator, the airbag and related
hardware are all part of the airbag modules. Frontal
airbag modules are located inside the steering wheel and
instrument panel. For seating positions with side impact
airbags, there are also airbag modules in the side of the
seatbacks closest to the door.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But the frontal
airbags would not help you in many types of collisions,
including rollovers, rear impacts, and many side impacts,
primarily because an occupant’s motion is not toward the
airbag. Side impact airbags would not help you in many
types of collisions, including many frontal or near frontal
collisions, and rear impacts, primarily because an
occupant’s motion is not toward those airbags.
1-64

Airbags should never be regarded as anything more than
a supplement to safety belts, and then only in moderate
to severe frontal or near-frontal collisions for the frontal
airbags, and only in moderate to severe side collisions for
vehicles with a side impact airbag.
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 may
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 seating positions with side impact
airbags, the side of the seatback closest to the door may
be hot. The parts of the airbag 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 out of the windshield
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.
1-65

The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine if the
passenger’s airbag or airbags should be enabled (may
inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child is
so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag and seat-mounted side impact airbag
(if equipped) under certain conditions, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is turned
off. General Motors recommends that
rear-facing child restraints be secured in the
rear seat, even if the airbag is off.
If you need to secure a forward-facing child
restraint in the right front seat, always move
the front passenger seat as far back as it will
go. It is better to secure the child restraint in a
rear seat.
1-67

The passenger sensing system is designed to turn off
the right front passenger’s airbag or airbags if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
rear-facing infant seat
the system determines that a small child is present
in a forward-facing child restraint
the system determines that a small child is present
in a booster seat
a right front passenger takes his/her weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
or if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
passenger’s airbag or airbags, the off indicator will
light and stay lit to remind you that the airbag or airbags
are off.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint
following the child restraint manufacturer’s directions
and refer toSecuring a Child Restraint in the Right Front
Seat Position on page 1-53.If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
The passenger sensing system is designed to enable
(may inate) the right front passenger’s airbag or airbags
anytime the system senses that a person of adult size
is sitting properly in the right front passenger’s seat.
When the passenger sensing system has allowed
the airbag or airbags to be enabled, the on indicator will
light and stay lit to remind you that the airbag or
airbags are active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
airbag or airbags, depending upon the person’s seating
posture and body build. Everyone in your vehicle
who has outgrown child restraints should wear a safety
belt properly — whether or not there is an airbag for
that person.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end or side sheet
metal or height, they may keep the airbag system
from working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the instrument panel can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2.

Restraint System Check
Checking the 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 airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)Notice:If you damage the covering for the driver’s
or the right front passenger’s frontal airbag, or
an airbag covering (if equipped) on a 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 frontal airbag, or both
the airbag module and the seatback for seating
positions with a side impact airbag (if equipped.) Do
not open or break the airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
If the frontal airbags inate you will also need to replace
the driver and front passenger’s safety belt retractor
assembly. Be sure to do so. Then the new retractor
assembly will be there to help protect you in a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt retractor assemblies, even
if the frontal airbags have not deployed. The driver
and front passenger’s safety belt retractor assemblies
contain the safety belt pretensioners. Have your
safety belt pretensioners checked if your vehicle has
been in a collision, or if your airbag readiness light stays
on after you start your vehicle or while you are driving.
SeeAirbag Readiness Light on page 3-38.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
From the outside, use your key or the remote keyless
entry transmitter.
To unlock the driver’s door from the outside with the
key, insert the key and turn it toward the front of
the vehicle. To lock the driver’s door from the outside
with your key, insert the key and turn it toward the rear
of the vehicle.
If your vehicle has power door locks, you may be able
to unlock all of the doors and the liftgate when you insert
the key, turn it toward the front of the vehicle, and
hold it there for one second. You may be able to lock all
of the doors when you insert the key and turn it toward
the rear of the vehicle.
