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.

Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. 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 or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
or airbag wiring can affect the
operation of the airbag system. In addition, the vehicle has a
passenger sensing system
for the right front passenger
position, which includes
sensors that are part of the
passenger 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).

Seats and Restraints 3-51
Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants
and all other children. Neither the
distance traveled nor the age and
size of the traveler changes the
need, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
{WARNING
Children can be seriously injured
or strangled if a shoulder belt
is wrapped around their neck
and the safety belt continues
to tighten. Never leave children
unattended in a vehicle and never
allow children to play with the
safety belts.Airbags plus lap‐shoulder belts
offer protection for adults and older
children, but not for young children
and infants. Neither the vehicle's
safety belt system nor its airbag
system is designed for them. Every
time infants and young children ride
in vehicles, they should have the
protection provided by appropriate
child restraints.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
{WARNING
Never do this.
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
(Continued)
WARNING (Continued)
40 km/h (25 mph), a 5.5 kg (12 lb)
infant will suddenly become a
110 kg (240 lb) force on a person's
arms. An infant should be
secured in an appropriate
restraint.

3-56 Seats and Restraints
A label on the sun visor says,
“Never put a rear-facing child
restraint 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
(Continued)
WARNING (Continued)
guarantee that an airbag will not
deploy under some unusual
circumstance, even though
it 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.
SeePassenger Sensing System
on page 3‑41 for additional
information.
When securing a child restraint in
a rear seating position, study the
instructions that came with the
child restraint to make sure it is
compatible with this vehicle. Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others. Always make
sure the child restraint is properly
secured.
Depending on where you place the
child restraint and the size of the
child restraint you may not be able
to access adjacent safety belt
assemblies or LATCH anchors
for additional passengers or
child restraints. Adjacent seating
positions should not be used if the
child restraint prevents access to
or interferes with the routing of the
safety belt.
Wherever a child restraint is
installed, be sure to secure the
child restraint properly.
Keep in mind that an unsecured
child restraint can move around in a
collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint in
the vehicle
—even when no child is
in it.

Seats and Restraints 3-67
Securing Child Restraints
(Right Front
Passenger Seat)
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint on
page 3‑55.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right front
passenger frontal airbag under
certain conditions. See Passenger
Sensing System on page 3‑41 and
Passenger Airbag Status Indicator
on page 5‑16 for more information,
including important safety
information.
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 deploy under some unusual
circumstance, even though it is
turned off.
(Continued)
WARNING (Continued)
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.
SeePassenger Sensing System
on page 3‑41 for additional
information.
If the child restraint has the
LATCH system, see Lower Anchors
and Tethers for Children (LATCH
System) on page 3‑57 for how and
where to install the child restraint
using LATCH. If a child restraint
is secured using a safety belt and
it uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System) on page 3‑57
for top tether anchor locations.

Black plate (68,1)GMC Acadia/Acadia Denali Owner Manual - 2011
3-68 Seats and Restraints
Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored,
or if the instructions that come with
the child restraint say that the top
strap must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back asit will go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag, the off indicator on
the passenger airbag status
indicator should light and stay
lit when the vehicle is started.
See Passenger Airbag Status
Indicator on page 5‑16. 2. Put the child restraint on
the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
4. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
5. Pull the shoulder belt all the wayout of the retractor to set the
lock. When the retractor lock is
set, the belt can be tightened but
not pulled out of the retractor.

Seats and Restraints 3-69
6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt,
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint,
it may be helpful to use your
knee to push down on the child
restraint as you tighten the belt.
Try to pull the belt out of
the retractor to make sure
the retractor is locked. If the
retractor is not locked repeat
Steps 5 and 6. 7. Before placing a child in the
child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side to side and back
and forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
If the airbags are off, the off
indicator in the passenger airbag
status indicator will come on and
stay on when the vehicle is started.
If a child restraint has been
installed and the on indicator is lit,
see “If the On Indicator is Lit for a
Child Restraint” underPassenger
Sensing System on page 3‑41 for
more information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
