Reclining Seatbacks

{

Warning

Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the seat belts
cannot do their job.

The shoulder belt will not be against
your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.

The lap belt could go up over your
abdomen. The belt forces would be there,
not at your pelvic bones. This could cause
serious internal injuries.

For proper protection when the vehicle is
in motion, have the seatback upright.
Then sit well back in the seat and wear
the seat belt properly.

Do not have a seatback reclined if the
vehicle is moving.

attached, and are not twisted.

Seat Belts

This section describes how to use seat belts
properly, and some things not to do.

{

Warning

Do not let anyone ride where a seat belt
cannot be worn properly. In a crash,
if you or your passenger(s) are not
wearing seat belts, injuries can be much
worse than if you are wearing seat belts.
You can be seriously injured or killed by
hitting things inside the vehicle harder or
by being ejected from the vehicle. In
addition, anyone who is not buckled up
can strike other passengers in the vehicle.

It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, passengers riding in these
areas are more likely to be seriously
injured or killed. Do not allow passengers
to ride in any area of the vehicle that is
not equipped with seats and seat belts.

Always wear a seat belt, and check that
all passenger(s) are restrained
properly too.

This vehicle has indicators as a reminder to
buckle the seat belts. See

Why Seat Belts Work

When riding in a vehicle, you travel as fast
as the vehicle does. If the vehicle stops
suddenly, you keep going until something
stops you. It could be the windshield, the
instrument panel, or the seat belts!

When you wear a seat belt, you and the
vehicle slow down together. There is more
time to stop because you stop over a longer
distance and, when worn properly, your
strongest bones take the forces from the
seat belts. That is why wearing seat belts
makes such good sense.

Questions and Answers About Seat Belts

Q: Will I be trapped in the vehicle after a

crash if I am wearing a seat belt?

You

could

—

whether you are

wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you

can

unbuckle and get out,

much

greater if you are belted.

Q: If my vehicle has airbags, why should I

have to wear seat belts?

Airbags are supplemental systems only.
They work

with

seat belts

—

not instead

of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection.

Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.

How to Wear Seat Belts Properly

Follow these rules for everyone's protection.

There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see

Older Children

Infants and Young Children

. Review

and follow the rules for children in addition
to the following rules.

It is very important for all occupants to
buckle up. Statistics show that unbelted
people are hurt more often in crashes than
those who are wearing seat belts.

There are important things to know about
wearing a seat belt properly.

Sit up straight and always keep your feet
on the floor in front of you (if possible).

Wear the lap part of the belt low and
snug on the hips, just touching the
thighs. In a crash, this applies force to the
strong pelvic bones and you would be
less likely to slide under the lap belt.

If you slid under it, the belt would apply
force on your abdomen. This could cause
serious or even fatal injuries.

Wear the shoulder belt over the shoulder
and across the chest. These parts of the
body are best able to take belt
restraining forces. The shoulder belt locks
if there is a sudden stop or crash.

Warning

You can be seriously injured, or even
killed, by not wearing your seat belt
properly.

Seats and Restraints

{

Warning

You can be seriously injured or killed if
the shoulder belt is worn behind your
back, under your legs, or wrapped around
your neck. The shoulder belt can tighten
but cannot be loosened if it is locked. The
shoulder belt locks when it is pulled all
the way out of the retractor. It unlocks
when the shoulder belt is allowed to go
all the way back into the retractor, but it
cannot do this if it is wrapped around
you. You may have to cut the seat belt if
it is locked and tightened around you.

Lap-Shoulder Belt

All seating positions in the vehicle have a
lap-shoulder belt.

The following instructions explain how to
wear a lap-shoulder belt properly.

1. Adjust the seat, if the seat is adjustable,

so you can sit up straight. To see how,
see

“

Seats

”

in the Index.

2. Pick up the latch plate and pull the belt

across you. Do not let it get twisted.
The lap-shoulder belt may lock if you
pull the belt across you very quickly.
If this happens, let the belt go back
slightly to unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a passenger
belt is pulled out all the way, the child
restraint locking feature may be
engaged. See

Child Restraint Systems

. If this occurs, let the belt go back

all the way and start again. If the
locking feature stays engaged after
letting the belt go back to stowed

position on the seat, move the seat
rearward or recline the seat until the
shoulder belt retractor lock releases.
Engaging the child restraint locking
feature in the front outboard seating
position may affect the passenger
sensing system. See

Passenger Sensing

System

If the webbing locks in the latch plate
before it reaches the buckle, tilt the latch
plate flat to unlock.

3. Push the latch plate into the buckle until

it clicks.
Pull up on the latch plate to make sure
it is secure. If the belt is not long
enough, see

Seat Belt Extender

Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.

4. If equipped with a shoulder belt height

adjuster, move it to the height that is
right for you. See

“

Shoulder Belt Height

Adjuster

”

later in this section for

instructions on use and important safety
information.

5. To make the lap part tight, pull up on

the shoulder belt.

To unlatch the belt, push the button on the
buckle. The belt should return to its stowed
position.

Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.

Before a door is closed, be sure the seat belt
is out of the way. If a door is slammed
against a seat belt, damage can occur to
both the seat belt and the vehicle.

Shoulder Belt Height Adjuster

The vehicle has a shoulder belt height
adjuster for the driver and front outboard
passenger seating positions.

Adjust the height so that the shoulder
portion of the belt is on the shoulder and
not falling off of it. The belt should be close
to, but not contacting, the neck. Improper
shoulder belt height adjustment could
reduce the effectiveness of the seat belt in a
crash. See

How to Wear Seat Belts Properly

GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/

Mexico-16402009) - 2023 - CRC - 3/28/22

Seats and Restraints

Press and hold the release button while
raising or lowering the height adjuster to
the desired position.

After the height adjuster is set to the
desired position, try to move it down
without pressing the release button to make
sure it has locked into position.

Seat Belt Pretensioners

This vehicle has seat belt pretensioners for
the front outboard occupants. Although the
seat belt pretensioners cannot be seen, they
are part of the seat belt assembly. They can
help tighten the seat belts during the early
stages of a moderate to severe frontal, near
frontal, or rear crash if the threshold
conditions for pretensioner activation are

met. Seat belt pretensioners can also help
tighten the seat belts in a side crash or a
rollover event.

Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other parts of
the vehicle

’

s seat belt system will need to

be replaced. See

Replacing Seat Belt System

Parts after a Crash

Do not sit on the outboard seat belt while
entering or exiting the vehicle or at any
time while sitting in the seat. Sitting on the
seat belt can damage the webbing and
hardware.

Rear Seat Belt Comfort Guides

Rear seat belt comfort guides may provide
added seat belt comfort for older children
who have outgrown booster seats and for
some adults. When installed on a shoulder
belt, the comfort guide positions the
shoulder belt away from the neck and head.

Comfort guides are available through your
dealer for the rear outboard seating
positions. Instructions are included with the
guides.

Seat Belt Use During Pregnancy

Seat belts work for everyone, including
pregnant women. Like all occupants, they
are more likely to be seriously injured if
they do not wear seat belts.

A pregnant woman should wear a
lap-shoulder belt, and the lap portion should
be worn as low as possible, below the
rounding, throughout the pregnancy.

The best way to protect the fetus is to
protect the mother. When a seat belt is
worn properly, it is more likely that the
fetus will not be hurt in a crash. For
pregnant women, as for anyone, the key to
making seat belts effective is wearing them
properly.

Seats and Restraints

Seat Belt Extender

If the vehicle's seat belt will fasten around
you, you should use it.

But if a seat belt is not long enough, your
dealer will order you an extender. Only a
GM dealer issued extender should be used.
When you go in to order it, take the
heaviest coat you will wear, so the extender
will be long enough for you. To help avoid
personal injury, do not let someone else use
it, and use it only for the seat it is made to
fit. The extender has been designed for
adults. Never use it for securing child
restraints. For more information on the
proper use and fit of seat belt extenders see
the instruction sheet that comes with the
extender.

Safety System Check

Periodically check the seat belt reminder,
seat belts, buckles, latch plates, retractors,
shoulder belt height adjusters (if equipped),
and seat belt anchorages to make sure they
are all in working order. Look for any other
loose or damaged seat belt system parts
that might keep a seat belt system from
performing properly. See your dealer to
have it repaired. Torn, frayed, or twisted
seat belts may not protect you in a crash.

Torn or frayed seat belts can rip apart under
impact forces. If a belt is torn or frayed,
have it replaced immediately. If a belt is
twisted, it may be possible to untwist by
reversing the latch plate on the webbing.
If the twist cannot be corrected, ask your
dealer to fix it.

Make sure the seat belt reminder light is
working. See

Seat Belt Reminders

Seat Belt Care

Keep belts clean and dry.

Seat belts should be properly cared for and
maintained.

Seat belt hardware should be kept dry and
free of dust or debris. As necessary, exterior
hard surfaces and seat belt webbing may be
lightly cleaned with mild soap and water.
Ensure there is not excessive dust or debris
in the mechanism. If dust or debris exists in
the system please see the dealer. Parts may
need to be replaced to ensure proper
functionality of the system.

Airbag System

The vehicle has the following airbags:

A frontal airbag for the driver

A frontal airbag for the front outboard
passenger

A knee airbag for the driver

A front center airbag for the driver and
front outboard passenger

A seat-mounted side impact airbag for the
driver

A seat-mounted side impact airbag for the
front outboard passenger

A roof-rail airbag for the driver and for
the second and third row passengers
seated directly behind the driver

A roof-rail airbag for the front outboard
passenger and the second and third row
passengers seated directly behind the
front outboard passenger

All vehicle airbags have the word AIRBAG on
the trim or on a label near the deployment
opening.

For frontal airbags, the word AIRBAG is on
the center of the steering wheel for the
driver and on the instrument panel for the
front outboard passenger.

For knee airbags, the word AIRBAG is on the
lower part of the instrument panel.

For the front center airbag, the word AIRBAG
is on the inboard side of the driver seatback.

For seat-mounted side impact airbags, the
word AIRBAG is on the side of the seatback
or side of the seat closest to the door.

For roof-rail airbags, the word AIRBAG is on
the ceiling or trim.

Airbags are designed to supplement the
protection provided by seat belts. Even
though today's airbags are also designed to
help reduce the risk of injury from the force
of an inflating bag, all airbags must inflate
very quickly to do their job.

Here are the most important things to know
about the airbag system:

{

Warning

You can be severely injured or killed in a
crash if you are not wearing your seat
belt, even with airbags. Airbags are
designed to work with seat belts, not
replace them. Also, airbags are not
designed to inflate in every crash. In
some crashes seat belts are the only
restraint. See

When Should an Airbag

Inflate?

Wearing your seat belt during a crash
helps reduce your chance of hitting
things inside the vehicle or being ejected
from it. Airbags are

to the seat belts. Everyone in

the vehicle should wear a seat belt
properly, whether or not there is an
airbag for that person.

Warning (Continued)

to any airbag when it inflates can be
seriously injured or killed. Do not sit
unnecessarily close to any airbag, as you
would be if sitting on the edge of the
seat or leaning forward. Seat belts help
keep you in position before and during a
crash. Always wear a seat belt, even with
airbags. The driver should sit as far back
as possible while still maintaining control
of the vehicle. The seat belts and the
front outboard passenger airbags are
most effective when you are sitting well
back and upright in the seat with both
feet on the floor.

Occupants should not lean on or sleep
against the front center armrest or
console in vehicles with a front center
airbag.

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.

{

Warning

Children who are up against, or very
close to, any airbag when it inflates can
be seriously injured or killed. Always
secure children properly in the vehicle. To
read how, see

Warning

If something is between an occupant and
an airbag, the airbag might not inflate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inflating airbag
must be kept clear. Do not put anything
between an occupant and an airbag, and

do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering.

Do not use seat or console accessories
that block the inflation path of a
seat-mounted side impact airbag or the
front center airbag.

Never secure anything to the roof of a
vehicle with roof-rail airbags by routing a
rope or tie-down through any door or
window opening. If you do, the path of
an inflating roof-rail airbag will be
blocked.

When Should an Airbag Inflate?

This vehicle is equipped with airbags. See

Airbag System

. Airbags are designed to

inflate if the impact exceeds the specific
airbag system's deployment threshold.
Deployment thresholds are used to predict
how severe a crash is likely to be in time
for the airbags to inflate and help restrain
the occupants. The vehicle has electronic
sensors that help the airbag system

determine the severity of the impact.
Deployment thresholds can vary with
specific vehicle design.

Frontal airbags are designed to inflate in
moderate to severe frontal crashes to help
reduce the potential for severe injuries,
mainly to the driver's or front outboard
passenger's head and chest.

Whether the frontal airbags will or should
inflate is not based primarily on how fast
the vehicle is traveling. It depends on what
is hit, the direction of the impact, and how
quickly the vehicle slows down.

Frontal airbags may inflate at different crash
speeds depending on whether the vehicle
hits an object straight on or at an angle,
and whether the object is fixed or moving,
rigid or deformable, narrow or wide.

Frontal airbags are not intended to inflate
during vehicle rollovers, in rear impacts,
or in many side impacts.

In addition, the vehicle has advanced
technology frontal airbags. Advanced
technology frontal airbags adjust the
restraint according to crash severity.

Knee airbags are designed to inflate in
moderate to severe frontal impacts. Knee
airbags are not designed to inflate during
vehicle rollovers, in rear impacts, or in many
side impacts.

The front center airbag is designed to inflate
in moderate to severe side crashes
depending on the location of the impact,
when either side of the vehicle is struck. In
addition, the front center airbag is designed
to inflate when the sensing system predicts
that the vehicle is about to roll over on its
side. The front center airbag is not designed
to inflate in frontal impacts, near frontal
impacts, or rear impacts.

Seat-mounted side impact airbags are
designed to inflate in moderate to severe
side crashes depending on the location of
the impact. These airbags may also inflate
in some moderate to severe frontal impacts.
Seat-mounted side impact airbags are not
designed to inflate in rollovers or rear
impacts. A seat-mounted side impact airbag
is designed to inflate on the side of the
vehicle that is struck.

Roof-rail airbags are designed to inflate in
moderate to severe side crashes depending
on the location of the impact. In addition,
these roof-rail airbags may inflate during a

GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/

Mexico-16402009) - 2023 - CRC - 3/28/22

Seats and Restraints

rollover or in a severe frontal impact.
Roof-rail airbags are not designed to inflate
in rear impacts. Both roof-rail airbags may
inflate when either side of the vehicle is
struck or if the sensing system predicts that
the vehicle is about to roll over on its side,
or in a severe frontal impact.

In any particular crash, no one can say
whether an airbag should have inflated
simply because of the vehicle damage or
repair costs.

What Makes an Airbag Inflate?

In a deployment event, the sensing system
sends an electrical signal triggering a release
of gas from the inflator. Gas from the
inflator fills the airbag causing the bag to
break out of the cover. The inflator, the
airbag, and related hardware are all part of
the airbag module.

For airbag locations, see

Where Are the

Airbags?

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 seat belts by distributing the force of the
impact more evenly over the
occupant's body.

Rollover capable roof-rail airbags are
designed to help contain the head and chest
of occupants in the outboard seating
positions in the first, 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. See

When Should an Airbag Inflate?

Airbags should never be regarded as
anything more than a supplement to seat
belts.

What Will You See after an
Airbag Inflates?

After frontal, knee, and seat-mounted side
impact airbags inflate, they quickly deflate,
so quickly that some people may not even
realize the airbags inflated. The front center
airbag and roof-rail airbags may still be at
least partially inflated for some time after
they inflate. Some components of the airbag
module may be hot for several minutes. For
location of the airbags, see

Where Are the

Airbags?

The parts of the airbag that come into
contact with you may be warm, but not too
hot to touch. There may be some smoke
and dust coming from the vents in the
deflated airbags. Airbag inflation does not
prevent the driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people from
leaving the vehicle.

{

Warning

When an airbag inflates, there may be
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 inflates, 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.

The vehicle has a feature that may
automatically unlock the doors, turn on the
interior lamps and hazard warning flashers,
and shut off the fuel system after the
airbags inflate. The feature may also
activate, without airbag inflation, after an
event that exceeds a predetermined
threshold. After turning the ignition off and
then on again, the fuel system will return to
normal operation; the doors can be locked,
the interior lamps can be turned off, and
the hazard warning flashers can be turned
off using the controls for those features.
If any of these systems are damaged in the
crash they may not operate as normal.

{

Warning

A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle, such
as the fuel system, brake and steering
systems, etc. Even if the vehicle appears
to be drivable after a moderate crash,
there may be concealed damage that
could make it difficult to safely operate
the vehicle.

Use caution if you should attempt to
restart the engine after a crash has
occurred.

In many crashes severe enough to inflate
the airbag, windshields are broken by
vehicle deformation. Additional windshield
breakage may also occur from the front
outboard passenger airbag.

Airbags are designed to inflate only once.
After an airbag inflates, you will need
some new parts for the 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 the vehicle
covers the need to replace other parts.

The vehicle has a crash sensing and
diagnostic module which records
information after a crash. See

Vehicle

Data Recording and Privacy

360

and

Event Data Recorders

Let only qualified technicians work on the
airbag systems. Improper service can
mean that an airbag system will not work
properly. See your dealer for service.

Passenger Sensing System

The vehicle has a passenger sensing system
for the front outboard passenger position.
The passenger airbag status indicator will
light on the overhead console when the
vehicle is started.

The words ON and OFF, and the symbols for
on and off, will be visible during the system
check. When the system check is complete,
either the word ON or OFF, and the symbol
for on or off, will be visible. See

GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/

Mexico-16402009) - 2023 - CRC - 3/28/22

Seats and Restraints

The passenger sensing system turns off the
front outboard passenger frontal airbag
under certain conditions. No other airbag is
affected by the passenger sensing system.

The passenger sensing system works with
sensors that are part of the front outboard
passenger seat and seat belt. The sensors
are designed to detect the presence of a
properly seated occupant and determine if
the front outboard passenger frontal airbag
should be allowed to inflate or not.

According to accident statistics, children are
safer when properly secured in a rear seat
in the correct child restraint for their weight
and size.

Whenever possible, children aged 12 and
under should be secured in a rear seating
position.

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
inflates.

{

Warning

A child in a rear-facing child restraint can
be seriously injured or killed if the
passenger frontal airbag inflates. This is

(Continued)

Warning (Continued)

because the back of the rear-facing child
restraint would be very close to the
inflating airbag. A child in a
forward-facing child restraint can be
seriously injured or killed if the passenger
frontal airbag inflates and the passenger
seat is in a forward position.

Even if the passenger sensing system has
turned off the passenger frontal airbag,
no system is fail-safe. No one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though the airbag is turned off.

Never put a rear-facing child restraint in
the front seat, even if the airbag is off.
If securing a forward-facing child restraint
in the front outboard passenger seat,
always move the seat as far back as it
will go. It is better to secure child
restraints in the rear seat. Consider using
another vehicle to transport the child
when a rear seat is not available.

The passenger sensing system is designed to
turn off the front outboard passenger
frontal airbag if:

The front outboard passenger seat is
unoccupied.

The system determines an infant is
present in a child restraint.

A front outboard passenger takes his/her
weight off of the seat for a period
of time.

There is a critical problem with the airbag
system or the passenger sensing system.

When the passenger sensing system has
turned off the front outboard passenger
frontal airbag, the OFF indicator will light
and stay lit as a reminder that the airbag is
off. See

Passenger Airbag Status Indicator

105

The passenger sensing system is designed to
turn on the front outboard passenger frontal
airbag anytime the system senses that a
person of adult size is sitting properly in the
front outboard passenger seat.

When the passenger sensing system has
allowed the airbag to be enabled, the ON
indicator will light and stay lit as a reminder
that the airbag is active.

For some children, including children in child
restraints, and for very small adults, the
passenger sensing system may or may not
turn off the front outboard passenger

for more information, including important
safety information.

If the On Indicator Is Lit for a Child
Restraint

The passenger sensing system is designed to
turn off the front outboard passenger
frontal airbag if the system determines that
an infant is present in a child restraint. If a
child restraint has been installed and the ON
indicator is lit:

1. Turn the vehicle off.
2. Remove the child restraint from the

vehicle.

3. Remove any additional items from the

seat such as blankets, cushions, seat
covers, seat heaters, or seat massagers.

4. Reinstall the child restraint following the

directions provided by the child restraint
manufacturer and refer to

Securing Child

Restraints (With the Seat Belt in the Rear
Seat)

Securing Child Restraints (With the Seat
Belt in the Front Seat)

Make sure the seat belt retractor is
locked by pulling the shoulder belt all
the way out of the retractor when
installing the child restraint, even if the
child restraint is equipped with a seat
belt lock off. When the retractor lock is
set, the belt can be tightened but not
pulled out of the retractor.

5. If, after reinstalling the child restraint

and restarting the vehicle, the ON
indicator is still lit, turn the vehicle off.
Then slightly recline the vehicle seatback
and adjust the seat cushion,
if adjustable, to make sure that the
vehicle seatback is not pushing the child
restraint into the seat cushion.

Also make sure the child restraint is not
trapped under the vehicle head restraint.
If this happens, adjust the head restraint.
See

Head Restraints

6. Restart the vehicle.

The passenger sensing system may or may
not turn off the airbag for a child in a child
restraint depending upon the child

’

s size.

It is better to secure the child restraint in a
rear seat. Never put a rear-facing child
restraint in the front seat, even if the ON
indicator is not lit.

Seats and Restraints

If a person of adult size is sitting in the
front outboard passenger seat, but the OFF
indicator is lit, it could be because that
person is not sitting properly in the seat or
that the child restraint locking feature is
engaged. Use the following steps to allow
the system to detect that person and enable
the front outboard passenger frontal airbag:

1. Turn the vehicle off.
2. Remove any additional material from the

seat, such as blankets, cushions, seat
covers, seat heaters, or seat massagers.

3. Place the seatback in the fully upright

position.

4. Have the person sit upright in the seat,

centered on the seat cushion, with legs
comfortably extended.

5. If the shoulder portion of the belt is

pulled out all the way, the child restraint
locking feature will be engaged. This
may unintentionally cause the passenger
sensing system to turn the airbag off for
some adult-sized occupants. If this
happens, unbuckle the belt, let the belt
go back all the way, and then buckle the
belt again without pulling the belt out
all the way.

6. Restart the vehicle and have the person

remain in this position for two to
three minutes after the ON indicator
is lit.

Warning

If the front outboard passenger airbag is
turned off for an adult-sized occupant,
the airbag will not be able to inflate and
help protect that person in a crash,
resulting in an increased risk of serious
injury or even death. An adult-sized
occupant should not ride in the front
outboard passenger seat, if the passenger
airbag OFF indicator is lit.

Additional Factors Affecting System
Operation

Seat 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

“

Seat Belts

”

and

“

Child Restraints

”

in the Index for

additional information about the importance
of proper restraint use.

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. We
recommend that you not use seat covers or
other aftermarket equipment except when
approved by GM for your specific vehicle.
See

Adding Equipment to the

Airbag-Equipped Vehicle

for more

information about modifications that can
affect how the system operates.

The ON indicator may be lit if an object,
such as a briefcase, handbag, grocery bag,
laptop, or other electronic device, is put on
an unoccupied seat. If this is not desired,
remove the object from the seat.

Warning

Stowing articles under the passenger seat
or between the passenger seat cushion
and seatback may interfere with the
proper operation of the passenger
sensing system.

Servicing the Airbag-Equipped
Vehicle

Airbags affect how the vehicle should be
serviced. There are parts of the airbag
system in several places around the vehicle.
Your dealer and the service manual have
information about servicing the vehicle and
the airbag system. To purchase a service
manual, see

Warning

For up to 10 seconds after the vehicle is
turned off and the battery is
disconnected, an airbag can still inflate
during improper service. You can be
injured if you are close to an airbag
when it inflates. 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 qualified to
do so.

Adding Equipment to the
Airbag-Equipped Vehicle

Adding accessories that change the vehicle's
frame, bumper system, height, front end,
or side sheet metal may keep the airbag
system from working properly.

The operation of the airbag system can also
be affected by changing, including
improperly repairing or replacing, any parts
of the following:

Airbag system, including airbag modules,
front or side impact sensors, sensing and
diagnostic module, airbag wiring, or front
center console

Front seats, including stitching, seams or
zippers

Seat belts

Steering wheel, instrument panel,
overhead console, ceiling trim, or pillar
garnish trim

Inner door seals, including speakers

Your dealer and the service manual have
information about the location of the airbag
modules and sensors, sensing and diagnostic
module, and airbag wiring along with the
proper replacement procedures.

In addition, the vehicle has a passenger
sensing system for the front outboard
passenger position, which includes sensors
that are part of the passenger's seat. The
passenger sensing system may not operate
properly if the original seat trim is replaced
with non-GM covers, upholstery, or trim,
or with GM covers, upholstery, or trim
designed for a different vehicle. Any object,
such as an aftermarket seat heater or a
comfort enhancing pad or device, installed
under or on top of the seat fabric, could
also interfere with the operation of the
passenger sensing system. This could either
prevent proper deployment of the passenger
airbag(s) or prevent the passenger sensing
system from properly turning off the
passenger airbag(s). See
