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.
The vehicle may or may not have
roof-rail airbags. SeeAirbag System
on page 3‑18. 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. 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 frontal impacts, near-frontal
impacts, or rear impacts. All roof-rail
airbags will deploy when either side
of the vehicle is struck.
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 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
roof-rail airbags, there are airbag
modules in the ceiling of the vehicle,
near the side windows for the first,
second, and third rows (if equipped).
See
Where Are the Airbags? on
page 3‑20 for more information.

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. 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, second, and third rows,
if equipped. The rollover capable
roof-rail airbags are designed to
help reduce the risk of full orpartial 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 3‑22
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 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 3‑23. 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.

WARNING (Continued)
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
(if equipped with power door locks),
turn on the interior lamps and
hazard warning flashers, and shut
off the fuel system after the
airbags inflate. You can lock the
doors, and turn off the interior lamps
and the 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 (Continued)
WARNING (Continued)
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
the 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 13‑20 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 the instrument panel has one of
the switches pictured in the
following illustrations, 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
Canada and Mexico
If the vehicle does not have an
airbag on-off switch, it may have a
passenger sensing system. See
Passenger Sensing System on
page 3‑30. 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.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
to inflate and help protect the
person sitting there.
Do not turn off the passenger
airbag unless the person sitting
there is in a risk group.

Passenger Sensing
System
If the instrument panel has one of
the indicators pictured in the
following illustrations, the vehicle
has a passenger sensing system
unless there is an airbag off switch
located on the instrument panel.
If there is an airbag off switch, the
vehicle does not have a passenger
sensing system. SeeAirbag On-Off
Switch on page 3‑26 for more
information.
United States
Canada and Mexico
The passenger airbag status
indicator will be visible on the
instrument panel when the vehicle is
started.
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. If you are
using remote start, if equipped, to
start the vehicle from a distance,
you may not see the system check.
When the system check is
complete, either the word ON or the
word OFF, or the symbol for on or
the symbol for off, will be visible.
See Passenger Airbag Status
Indicator on page 5‑20. The passenger sensing system will
turn off the right front passenger
frontal airbag under certain
conditions.
The driver airbag and roof-rail
airbags, if equipped, are not part of
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.

Black plate (31,1)Chevrolet Express Owner Manual - 2012
Seats and Restraints 3-31
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.
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.
(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.
If the vehicle does not have a
rear seat that will accommodate a
rear-facing child restraint, a
rear-facing child restraint should not
be installed in the vehicle, even if
the airbag is off.

Black plate (32,1)Chevrolet Express Owner Manual - 2012
3-32 Seats and Restraints
The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:
.The right front passenger seat is
unoccupied.
.The system determines that an
infant is present in a rear-facing
infant seat.
.The system determines that a
small child is present in a child
restraint.
.The system determines that a
small child is present in a
booster seat.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.The right front passenger seat is
occupied by a smaller person,
such as a child who has
outgrown child restraints.
.Or, if there is a critical problem
with the airbag system or the
passenger sensing system.When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit to
remind you that the airbag is off.
See
Passenger Airbag Status
Indicator on page 5‑20.
The passenger sensing system is
designed to turn on (may inflate) the
right front passenger frontal airbag
anytime the system senses that a
person of adult size is sitting
properly in the right front
passenger seat.
When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that the
airbag is active.
For some children who have
outgrown child restraints and for
very small adults, the passenger
sensing system may or may not turn
off the right front passenger frontal
airbag, depending upon the
person's seating posture and
body build. Everyone in the vehicle who
has outgrown child restraints
should wear a safety belt
properly
—whether or not there
is an airbag for that person.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light on page 5‑18 for more
information, including important
safety information.
