Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them.
In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Replacing Safety Belt
System Parts After a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in
a crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon
as possible.After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 5‑22.

Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front
passenger.
The vehicle may have the following
airbags:
.A seat‐mounted side impact
airbag for the driver.
.A seat‐mounted side impact
airbag for the right front
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the right
front passenger and the person
seated directly behind the right
front passenger. All of the airbags in the vehicle will
have the word AIRBAG embossed
in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger.
With seat‐mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the
headliner or trim.
Airbags are designed to supplement
the protection provided by safety
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 safety belt
—even
if you have airbags. Airbags are
designed to work with safety
belts, but do not replace them.
Also, airbags are not designed to
deploy in every crash. In some
crashes safety belts are your only
restraint. See When Should an
Airbag Inflate? on page 3‑34.
Wearing your safety belt during a
crash helps reduce your chance
of hitting things inside the vehicle
or being ejected from it. Airbags
are “supplemental restraints” to
the safety belts. Everyone in your
vehicle should wear a safety belt
properly —whether or not there is
an airbag for that person.

Black plate (32,1)Chevrolet Silverado Owner Manual - 2011
3-32 Seats and Restraints
{WARNING
Airbags inflate with great force,
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 the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear your 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's
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
your vehicle. To read how, see
Older Children
on page 3‑51or
Infants and Young Children
on
page 3‑53
.
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 5‑22for more information.

{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into (Continued)
WARNING (Continued)
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 (35,1)Chevrolet Silverado Owner Manual - 2011
Seats and Restraints 3-35
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's door. See
Vehicle
Load Limits
on page 9‑23for 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.

3-36 Seats and Restraints
The vehicle may or may not have
seat‐mounted side impact and
roof-rail airbags. SeeAirbag System
on page 3‑31. 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.
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.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 3‑34for 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 3‑36.
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. 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.
