{WARNING
Because airbags inflate with great
force and faster than the blink of
an eye, anyone who is up
against, or very close 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. Safety belts help keep
you in position before and during
a crash. Always wear a 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.
{WARNING
Children who are up against,
or very close to, any airbag
when it inflates can be seriously
injured or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children,
but not for young children and
infants. Neither the vehicle
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 the vehicle. To read how, see
Older Children on page 3‑42or
Infants and Young Children on
page 3‑44.
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol.
The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See Airbag
Readiness Light on page 5‑20
for more information.

If the vehicle has roof-rail airbags
for the driver, right front passenger,
and second row outboard
passengers, they 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 your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.

Black plate (27,1)Chevrolet Silverado Owner Manual - 2012
Seats and Restraints 3-27
Frontal airbags may inflate at
different crash speeds.
For example:
.If the vehicle hits a stationary
object, the airbags could inflate
at a different crash speed than if
the vehicle hits a moving object.
.If the vehicle hits an object that
deforms, the airbags could
inflate at a different crash speed
than if the vehicle hits an object
that does not deform.
.If the vehicle hits a narrow object
(like a pole), the airbags could
inflate at a different crash speed
than if the vehicle hits a wide
object (like a wall).
.If the vehicle goes into an object
at an angle, the airbags could
inflate at a different crash speed
than if the vehicle goes straight
into the object.
Thresholds can also vary with
specific vehicle design.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts. If the GVWR (Gross Vehicle Weight
Rating) of your vehicle is 3 855 kg
(8,500 lb) or above, the vehicle has
single stage airbags. If the GVWR is
below 3 855 kg (8,500 lb) then the
vehicle has dual stage airbags.
Vehicles with a full bench seat are
equipped with single state airbags.
You can find the GVWR on the
certification label on the rear edge
of the driver door. See
Vehicle Load
Limits on page 9‑17 for more
information.
The vehicle may have dual‐stage
frontal airbags. Dual-stage airbags
adjust the restraint according to
crash severity. The vehicle has
electronic frontal sensors, which
help the sensing system distinguish
between a moderate frontal impact
and a more severe frontal impact.
For moderate frontal impacts,
dual-stage airbags inflate at a
level less than full deployment.
For more severe frontal impacts,
full deployment occurs. Vehicles with dual stage airbags
also have seat position sensors
which enable the sensing system to
monitor the position of the driver
seat (all models), and on crew cab
and extended cab models the right
front passenger seat on light duty
models only. The seat position
sensor provides information that is
used to determine if the airbags
should deploy at a reduced level or
at full deployment.
The vehicle may or may not have
seat‐mounted side impact and
roof-rail airbags. See
Airbag System
on page 3‑23. Seat‐mounted side
impact and roof-rail airbags are
intended to inflate in moderate to
severe side crashes. In addition,
these roof-rail airbags are intended
to inflate during a rollover or in a
severe frontal impact. Seat‐mounted
side impact and roof-rail airbags will
inflate if the crash severity is above
the system's designed threshold
level. The threshold level can vary
with specific vehicle design.

Black plate (28,1)Chevrolet Silverado Owner Manual - 2012
3-28 Seats and Restraints
Roof-rail airbags are not
intended to inflate in rear impacts.
A seat‐mounted side impact airbag
is intended to deploy on the side of
the vehicle that is struck. Both
roof-rail airbags will deploy when
either side of the vehicle is struck,
or if the sensing system predicts
that the vehicle is about to roll over,
or in a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
damage to a vehicle or because
of what the repair costs were.
For frontal airbags, inflation is
determined by what the vehicle hits,
the angle of the impact, and how
quickly the vehicle slows down.
For seat‐mounted side impact and
roof-rail airbags, deployment is
determined by the location and
severity of the side impact. In a
rollover event, roof-rail airbag
deployment is determined by the
direction of the roll.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 airbags 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.

Black plate (29,1)Chevrolet Silverado Owner Manual - 2012
Seats and Restraints 3-29
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 3‑26 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 3‑28.
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 may have 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 (30,1)Chevrolet Silverado Owner Manual - 2012
3-30 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 13‑19 andEvent Data
Recorders on page 13‑20.
.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.
Airbag On-Off Switch
If one of the switches pictured in the
following illustrations is located in
the glove box, the vehicle has an
airbag on-off switch that you can
use to manually turn on or off the
right front passenger airbag.
United States

If the vehicle does not have an
airbag off switch, it may have a
passenger sensing system.
See Passenger Sensing System on
page 3‑34. This switch should only be turned
to the off position if the person in
the right front passenger position is
a member of a passenger risk
group identified by the national
government as follows:
Infant. An infant (less than 1 year
old) must ride in the front seat
because:
.My vehicle has no rear seat;
.My vehicle has a rear seat
too small to accommodate a
rear-facing infant seat; or
.The infant has a medical
condition which, according to
the infant's physician, makes it
necessary for the infant to ride in
the front seat so that the driver
can constantly monitor the
child's condition.Child age 1 to 12. A child
age 1 to 12 must ride in the front
seat because:
.My vehicle has no rear seat;
.Although children ages 1 to 12
ride in the rear seat(s) whenever
possible, children ages 1 to 12
sometimes must ride in the front
because no space is available in
the rear seat(s) of my vehicle; or
.The child has a medical
condition which, according to
the child's physician, makes it
necessary for the child to ride in
the front seat so that the driver
can constantly monitor the
child's condition.

3-32 Seats and Restraints
Medical Condition. A passenger
has a medical condition which,
according to his or her physician:
.Causes the passenger airbag
to pose a special risk for the
passenger; and
.Makes the potential harm from
the passenger airbag in a crash
greater than the potential harm
from turning off the airbag and
allowing the passenger, even if
belted, to hit the instrument
panel or windshield in a crash.
{WARNING
If the right front passenger airbag
is turned off for a person who is
not in a risk group identified by
the national government, that
person will not have the extra
protection of an airbag. In a
crash, the airbag will not be able(Continued)
