2010 GMC CANYON Owner's Manual

When Should an Airbag Inate?
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 your 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.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.

Your vehicle has seat position sensors which enables
the sensing system to monitor the position of the driver’s
seat and the right front passenger’s seat. Seat position
sensors provide information that is used to determine
if the airbags should deploy at a reduced level or at full
deployment.
In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your 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.
Your vehicle may or may not have roof-rail airbags.
SeeAirbag System on page 2-64. Roof-rail airbags are
intended to inflate in moderate to severe side crashes.
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, rollovers, or rear impacts.
Both 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.
2-70

What Makes an Airbag Inate?
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 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. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
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
Inate? on page 2-69for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
2-71

What Will You See After an Airbag
Inates?
After the frontal airbags inflate, they quickly deflate, so
quickly that some people may not even realize the
airbags 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 Inate? on page 2-71.
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.
Your vehicle has a feature that may automatically
unlock the doors (if equipped with power door locks),
turn the interior lamps on, flash the hazard warning
flashers, and turn off the radio when the airbag inflates.
You can lock the doors again by using the door lock.
The interior lamps and hazard warning flashers will
deactivate after approximately 15 minutes.
2-72

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.
•Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 8-16andEvent Data Recorders on page 8-17.
•Let only qualified technicians work on the airbag
system. Improper service can mean that the
airbag system will not work properly. See your
dealer/retailer for service.
Passenger Sensing System
If the vehicle has one of the passenger airbag status
indicators pictured in the following illustrations, then the
vehicle has a passenger sensing system for the right
front passenger position. The passenger airbag status
indicator, If equipped, is visible on the instrument panel
when the vehicle is started.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle’s sun visors refer to “ADVANCED
AIRBAGS”.
2-73

The words ON and OFF, or the symbol for on and off,
will be visible during the system check. When the
system check is complete, either the word ON or OFF,
or the symbol for on or off will be visible. See
Passenger Airbag Status Indicator on page 4-23.
The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag is 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 and infants are
safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
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.
We recommend that rear-facing child restraints not be
transported in the vehicle, even if the airbag is off. United States

A label on your 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.
WARNING: (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 your 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.
The passenger sensing system is designed to turn off
the right front passenger 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.
2-75

•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.
SeePassenger Airbag Status Indicator on page 4-23.
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’s
frontal airbag, depending upon the person’s seating
posture and body build. Everyone in your 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. SeeAirbag Readiness Light on page 4-22
for more information, including important safety
information.
