2007 GMC ENVOY airbag

If your vehicle has a roof-mounted airbag for the
driver and the person seated directly behind
the driver, it is located in the ceiling above the
side windows.If your vehicle has a roof-mounted airbag for the
right front passenger and the person directly
behind that passenger, it is located in the ceiling
above the side windows.

{CAUTION:
If something is between an occupant and
an airbag, the bag might not inate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inating 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. And, if your vehicle
has roof-mounted side impact airbags,
never secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening. If
you do, the path of an inating side
impact airbag will be blocked. The path of
an inating airbag must be kept clear.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate
to severe frontal or near-frontal crashes. But
they are designed to inate only if the impact
exceeds a predetermined deployment threshold.
Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a
crash is likely to be in time for the airbags to inate
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.
In addition, your vehicle has “dual stage” frontal
airbags, which adjust the restraint according
to crash severity. Your vehicle has electronic
frontal sensors, which helps the sensing system
distinguish between a moderate frontal impact
and a more severe frontal impact. For moderate
frontal impacts, these airbags inate at a level
less than full deployment. For more severe
frontal impacts, full deployment occurs.
77

If the front of your vehicle goes straight into a
wall that does not move or deform, the threshold
level for the reduced deployment is about
9 to 16 mph (14 to 26 km/h), and the threshold
level for a full deployment is about 18 to 25 mph
(29 to 40 km/h). The threshold level can vary,
however, with specic vehicle design, so that it
can be somewhat above or below this range.
Frontal airbags may inate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could inate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate 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 inate 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 inate at a different crash
speed than if the vehicle goes straight into
the object.Frontal airbags (driver and right front passenger)
are not intended to inate 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.
Your vehicle may or may not have roof-mounted
airbags and a rollover sensor. SeeAirbag
System on page 71. These “rollover capable”
airbags are intended to inate in moderate
to severe side crashes or during a rollover.
A roof-mounted airbag will inate if the crash
severity is above the system’s designed “threshold
level.” The threshold level can vary with specic
vehicle design. Roof-mounted airbags are not
intended to inate in frontal or near-frontal impacts,
or rear impacts. Both roof-mounted airbags will
deploy when either side of the vehicle is struck
or during a rollover.
78

In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted airbags, ination is
determined by the location and severity of the
impact.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
SeeOff-Road Driving on page 319for tips on
off-road driving.What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is
in a crash. Additionally, in the case of a “rollover
capable” roof-mounted side impact airbag, the
sensing system detects that the vehicle is about to
roll over. The sensing system triggers a release
of gas from the inator, which inates the
airbag. The inator, airbag, and related hardware
are all part of the airbag modules inside the
steering wheel and in the instrument panel in front
of the right front passenger. For vehicles with
roof-mounted rollover airbags, the airbag modules,
the inator, and the airbags are located in the
ceiling of the vehicle, near the side windows.

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. Airbags distribute the force of the
impact more evenly over the occupant’s upper
body, stopping the occupant more gradually.
But the frontal airbags would not help you in
many types of collisions, including rollovers, rear
impacts, and many side impacts, primarily because
an occupant’s motion is not toward the airbag.
Roof-mounted rollover airbags would not help
you in many types of collisions, including many
frontal or near frontal collisions, and rear impacts.
Airbags should never be regarded as anything
more than a supplement to safety belts, and
then only in moderate to severe frontal or
near-frontal collisions for the driver’s and right
front passenger’s frontal airbags, and only
in moderate to severe side collisions or rollovers
for vehicles with roof-mounted rollover airbags.
What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize
an airbag inated. Roof-mounted rollover airbags
may still be at least partially inated minutes
after the vehicle comes to rest. Some components
of the airbag module — the steering wheel hub
for the driver’s airbag, the instrument panel for
the right front passenger’s airbag, and the
area along the ceiling of the vehicle near the side
windows for vehicles with roof–mounted side
impact airbags — may be hot for a short time.
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 deated airbags. Airbag ination
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.

{CAUTION:
When an airbag inates, 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 inates, 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, turn the interior lamps on, and
ash the hazard warning ashers when the airbags
inate. You can lock the doors again, turn the
interior lamps off, and turn off the hazard warning
ashers by using the controls for those features.In many crashes severe enough to inate the
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger airbag.Airbags are designed to inate only once.
After an airbag inates, you will need some
new parts for your 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 Collection
and Event Data Recorders on page 538.
Let only qualied technicians work on the
airbag system. Improper service can mean
that an airbag system will not work properly.

Passenger Sensing System
Your vehicle has a passenger sensing system for
the right front passenger’s position. A passenger
airbag status indicator in the rearview mirror will
be visible when you turn your ignition key to
START or RUN.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 the word OFF, or the symbol for
on or the symbol for off, will be visible. See
Passenger Airbag Status Indicator on page 202.
The passenger sensing system will turn off
the right front passenger’s frontal airbag under
certain conditions. The driver’s airbags are not
part of the passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s frontal
airbag should be enabled (may inate) or not.
Accident statistics show that children are safer
if they are restrained in the rear rather than
the front seat. We recommend that child restraints
be secured in a rear seat, including an infant
riding in a rear-facing infant seat, a child riding
in a forward-facing child seat, and an older
child riding in a booster seat.

If your vehicle has a rear seat that will
accommodate a rear-facing child restraint, 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.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
CAUTION: (Continued)
CAUTION: (Continued)
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If you need to 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.
