Driver Side shown,
Passenger Side similar
The roof-rail airbags for the driver,
right front passenger, passengers
behind the driver and right front
passenger, and the third row
outboard passengers are in the
ceiling above the side windows.
{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 accessories
that block the inflation path of a
seat-mounted side impact 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?
Frontal airbags are designed
to inflate in moderate to severe
frontal or near frontal crashes to
help reduce the potential for severe
injuries mainly to the driver's or right
front passenger's head and chest.
However, they are only designed
to inflate if the impact exceeds
a predetermined 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.
Whether the frontal airbags will
or should deploy is not based on
how fast the vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly the vehicle slows down.

Seats and Restraints 3-39
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in
the outboard seating positions
in the first and second 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 3‑36 for more
information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.What Will You See After
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, see What Makes
an Airbag Inflate? on page 3‑38.
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.

Black plate (40,1)GMC Acadia/Acadia Denali Owner Manual - 2011
3-40 Seats and Restraints
You can lock the doors, turn off the
interior lamps and hazard warning
flashers by using the controls for
those features.
{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 right front
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 your 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 on
page 13‑18 andEvent Data
Recorders on page 13‑18.
.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.

3-42 Seats and Restraints
A label on the 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.
{WARNING
A child in a rear-facing child
restraint can be seriously
injured or killed if the right
front passenger airbag inflates.
This is 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 right front
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag,
no system is fail-safe. No one can
guarantee that an airbag will not
(Continued)
WARNING (Continued)
deploy under some unusual
circumstance, even though the
airbag is turned off.
Secure rear-facing child
restraints in a rear seat, even if
the airbag is off. If you 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.
The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:
.The right front passenger seat is
unoccupied.
.The system determines that
an infant is present in a child
restraint.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.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 right front
passenger frontal airbag, the off
indicator will light and stay lit to
remind you that the airbag is off.
See Passenger Airbag Status
Indicator on page 5‑16.
The passenger sensing system is
designed to turn on (may inflate) the
right front passenger frontal airbag
anytime the system senses that
a person of adult size is sitting
properly in the right front
passenger seat.
When the passenger sensing
system has allowed the airbag to
be enabled, the on indicator will
light and stay lit to remind you
that the airbag is active.

Seats and Restraints 3-43
For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not
turn off the right front passenger
frontal airbag, depending upon
the person’s seating posture
and body build. Everyone in the
vehicle who has outgrown child
restraints should wear a safety
belt properly —whether or not
there is an airbag for that person.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light on page 5‑15 for more
information, including important
safety information.
If the On Indicator is Lit for 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 (Rear
Seat) on page 3‑65 orSecuring
Child Restraints (Right Front
Passenger Seat) on page 3‑67. 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
on page 3‑2.
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 seating posture and body
build. It is better to secure the
child restraint in a rear seat.

Seats and Restraints 3-45
A wet seat can affect the
performance of the passenger
sensing system. Here is how:
.The passenger sensing system
may turn off the passenger
airbag when liquid is soaked
into the seat. If this happens,
the off indicator will be lit, and
the airbag readiness light on the
instrument panel will also be lit.
.Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will enable (turn
on) the passenger airbag while a
child restraint or child occupant
is on the seat. If the passenger
airbag is turned on, the on
indicator will be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install
a child restraint or allow anyone
to occupy the seat. See Airbag
Readiness Light on page 5‑15
for important safety information. 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 of 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
Service Publications Ordering
Information on page 13‑15.
{WARNING
For up to 10 seconds after the
ignition 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.

Replacing Airbag System
Parts After a Crash
{WARNING
A crash can damage the
airbag systems in the vehicle.
A damaged airbag system
may not work properly and
may not protect you and your
passenger(s) in a crash, resulting
in serious injury or even death.
To help make sure the airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon
as possible.If an airbag inflates, you will need
to replace airbag system parts.
See your dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly.
Have the vehicle serviced right
away. See
Airbag Readiness Light
on page 5‑15 for more information.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle safety belts.

3-50 Seats and Restraints
{WARNING
Never do this.
Never allow two children to wear
the same safety belt. The safety
belt can not properly spread the
impact forces. In a crash, the two
children can be crushed together
and seriously injured. A safety
belt must be used by only one
person at a time.
{WARNING
Never do this.
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly.
In a crash, the child would not be
restrained by the shoulder belt.
The child could move too far(Continued)
WARNING (Continued)
forward increasing the chance of
head and neck injury. The child
might also slide under the lap
belt. The belt force would then
be applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
