Reclining Seatbacks
{WARNING
You can lose control of the
vehicle if you try to adjust a
manual driver seat while the
vehicle is moving. The sudden
movement could startle and
confuse you, or make you push
a pedal when you do not want to.
Adjust the driver seat only when
the vehicle is not moving.
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
{WARNING
Sitting in a reclined position when
your vehicle is in motion can be
dangerous. Even if you buckle up,
your safety belts cannot do their
job when you are reclined
like this.(Continued)
WARNING (Continued)
The shoulder belt cannot do its
job. In a crash, you could go into
it, receiving neck or other injuries.
The lap belt cannot do its job
either. In a crash the belt could go
up over your abdomen. The belt
forces would be there, not at your
pelvic bones. This could cause
serious internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear your
safety belt properly.

Occupants who are not buckled up
can be thrown out of the vehicle in a
crash. And they can strike others in
the vehicle who are wearing safety
belts.
First, before you or your
passenger(s) wear a safety belt,
there is important information
you should know.
Sit up straight and always keep
your feet on the floor in front of you.
The lap part of the belt should beworn low and snug on the hips, just
touching the thighs. In a crash, this
applies force to the strong pelvic
bones and you would be less likely
to slide under the lap belt. If you
slid under it, the belt would apply
force on your abdomen. This could
cause serious or even fatal injuries.
The shoulder belt should go over
the shoulder and across the chest.
These parts of the body are best
able to take belt restraining forces.
The shoulder belt locks if there is a
sudden stop or crash.
Q: What is wrong with this?
A:
The shoulder belt is too loose.
It will not give as much
protection this way.

{WARNING
You can be seriously injured by a
twisted belt. In a crash, you would
not have the full width of the belt
to spread impact forces. If a belt
is twisted, make it straight so it
can work properly, or ask your
dealer to fix it.
Lap-Shoulder Belt
If the vehicle is a regular cab,
then all seating positions in the
vehicle have a lap-shoulder belt.
If the vehicle is a crew or extended
cab, then all seating positions in
the vehicle have a lap-shoulder
belt except for the center front
passenger position (if equipped),
which has a lap belt. SeeLap Belt
(Crew and Extended Cab)
on
page 3‑28for more information.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index. 2. Pick up the latch plate and pull
the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out
all the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
Engaging the child restraint
locking feature may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System
on page 3‑42for more information.

Extended Cab
On the extended cab, push down
on the release button (A) and move
the height adjuster to the desired
position.
You can move the adjuster up just
by pushing up on the shoulder belt
guide. After you move the adjuster to
where you want it, try to move it
down, without squeezing the buttons
for the regular and crew cabs,
or without pushing the release
button for extended cabs, to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety
belt pretensioners cannot be seen,
they are part of the safety belt
assembly. They can help tighten
the safety belts during the early
stages of a moderate to severe
frontal, near frontal, or rear crash
if the threshold conditions for
pretensioner activation are met.
And, if your vehicle has side impact
airbags, safety belt pretensioners
can help tighten the safety belts in
a side crash or a rollover event.Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced,
and probably other new parts
for the vehicle's safety belt system.
See
Replacing Safety Belt System
Parts After a Crash on page 3‑30.
Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they
are available through your dealer.
The guides may provide added
safety belt comfort for older children
who have outgrown booster seats
and for some adults. When installed
and properly adjusted, the comfort
guide positions the belt away from
the neck and head.

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 (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 (38,1)Chevrolet Silverado Owner Manual - 2011
3-38 Seats and Restraints
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.
