belt GMC ACADIA 2007 Workshop Manual

{CAUTION:
Airbags inate with great force, faster
than the blink of an eye. Anyone who is
up against, or very close to, any airbag
when it inates can be seriously injured
or killed. Do not sit unnecessarily close to
the airbag, as you would be if you were
sitting on the edge of your seat or leaning
forward. Safety belts help keep you in
position before and during a crash.
Always wear your safety belt, even with
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 or side windows in
seating positions with seat-mounted side
impact airbags and/or roof-rail airbags.
{CAUTION:
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 48orInfants and Young Children
on page 51.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas
from the inator. Gas from the inator lls
the airbag causing the bag to break out of the
cover and deploy. The inator, the airbag,
and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with seat-mounted side impact airbags, there
are airbag modules in the side of the front
seatbacks closest to the door. For vehicles with
roof-rail airbags, there are airbag modules in
the ceiling of the vehicle, near the side windows
that have occupant seating positions.
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.Airbags supplement the protection provided by
safety belts.
Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body,
stopping the occupant more gradually.
Seat-mounted side impact and roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants
in the outboard seating positions in the rst,
second, and third rows. The rollover capable
roof-rail airbags are designed to help reduce the
risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of
collisions, primarily because the occupant’s motion
is not toward those airbags. SeeWhen Should
an Airbag Inflate? on page 81for more information.
Airbags should never be regarded as anything
more than a supplement to safety belts.
83

The passenger sensing system will turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver’s airbags are not part of the
passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger’s frontal
airbag and seat-mounted side impact airbag
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.
We recommend that children be secured in a rear
seat, including: an infant or a child riding in a
rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large
enough, using safety belts.
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 right
front passenger’s frontal and
seat-mounted side impact airbag if the
system detects a rear-facing child
restraint, 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. We
recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbags are off.
CAUTION: (Continued)
86

Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. SeeHead Restraints
on page 17.
Remove any additional material from the seat
cushion before reinstalling or securing the
child 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/retailer.
The passenger sensing system is designed to
enable (may inate) the right front passenger’s
frontal airbag and seat-mounted side impact airbag
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 airbags to be enabled, the
on indicator will light and stay lit to remind you
that the 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 frontal airbag and
seat-mounted side impact airbag, 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.
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 two to three minutes. This will allow the
system to detect that person and then enable the
right front passenger’s frontal airbag and
seat-mounted side impact airbag.
88

Safety belts help keep the passenger in position
on the seat during vehicle maneuvers and braking,
which helps the passenger sensing system
maintain the passenger airbag status. See “Safety
Belts” and “Child Restraints” in the Index for
additional information about the importance of
proper restraint use.
{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 airbag(s). SeeAirbag
Readiness Light on page 217for more on
this, including important safety
information.
A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the
exterior 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, height,
front end or side sheet metal, 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. See Customer
Satisfaction Procedure.
If your vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on
page 452for additional important information.
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, steering wheel,
instrument panel, roof-rail airbag modules,
ceiling headliner, and pillar garnish trim, side
impact sensors, rollover sensor module,
or airbag wiring 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 518.
Your dealer/retailer and the service manual have
information about the location of the airbag
sensors, sensing and diagnostic module and
airbag wiring.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors, and anchorages are working properly.
SeeSafety Belt Reminder Light on page 216
for more information.
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. Keep safety belts clean and dry. See
Care of Safety Belts on page 482for more
information.
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.
Airbag System
The airbag system does not need regularly
scheduled maintenance or replacement. Make
sure the airbag readiness light is working.
SeeAirbag Readiness Light on page 217for more
information.
Notice:If an airbag covering is damaged,
opened, or broken, the airbag may not work
properly. Do not open or break the airbag
coverings. If there are any opened or broken
airbag covers, have the airbag covering and/or
airbag module replaced. For the location of
the airbag modules, seeWhat Makes an Airbag
Inflate? on page 83. See your dealer/retailer
for service.

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 any airbag inates, 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. See
Airbag Readiness Light on page 217.

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.
CAUTION: (Continued)
CAUTION: (Continued)

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.
The vehicle’s doors can be manually locked or
unlocked in the following ways:
From the outside, use the key in the
driver’s door.
From the inside, use the lock control on
the door.
