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 and deploy. The inflator,
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
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. See
When
Should an Airbag Inflate?
on
page 2‑29for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.

2-32 Seats and Restraints
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, seeWhat Makes
an Airbag Inflate? on page 2‑31.
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. 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.

2-34 Seats and Restraints
The passenger sensing system
turns off the right front passenger
frontal airbag under certain
conditions. The driver airbag,
seat‐mounted side impact airbags
and the roof-rail airbags are not
affected by the passenger sensing
system.
The passenger sensing system
works with sensors that are part of
the right front passenger seat. The
sensors are designed to detect the
presence of a properly-seated
occupant and determine if the right
front passenger frontal airbag
should be enabled (may 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.
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 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.
(Continued)
WARNING (Continued)
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 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.

Seats and Restraints 2-39
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
rollover sensor module, 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). See
Passenger Sensing System

WARNING (Continued)
Never carry something longer or
wider than the roof rack on top of
the vehicle unless using a GM
Certified accessory carrier.
This vehicle may be equipped with a
roof rack. For roof racks that do not
have cross rails included, GM
Certified cross rails can be
purchased as an accessory. See
your dealer/retailer for additional
information.
Notice: Loading cargo on the
roof rack that weighs more than
100 kg (220 lbs) or hangs over the
rear or sides of the vehicle may
damage the vehicle. Load cargo
so that it rests evenly between
the crossrails, making sure to
fasten cargo securely. To prevent damage or loss of cargo
when driving, check to make sure
cross rails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle's center
of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to
make sure the cargo remains in its
place. Do not exceed the maximum
vehicle capacity when loading the
vehicle. For more information on
vehicle capacity and loading, see
Vehicle Load Limits on page 8‑22.
The roof rack crossrails can be
locked in four positions along the
roof rack side rails.

3-4 Storage
Lift the lever to release and move
the crossrail.
Position the crossrail on both sides
of the vehicle at the same time.Push the lever down to completely
engage into the side rail holes.
Slide the crossrails back and forth
until the lock pins engage in the
holes and a click is heard as the
pins align and the crossrail locks.Try sliding the crossrails forward
and backward to ensure that they
are correctly secured and that the
levers stay tight to the cross rails.
Do not stand on the plastic lower
body panels when loading cargo on
the luggage carrier.
When the roof rack is not in use,
lock one crossrail at the furthest
forward position and lock the other
crossrail at the furthest rearward
position to reduce wind noise.
