SEATS AND RESTRAINTS 77
Warning (Continued)
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?
This vehicle is equipped with airbags.
SeeAirbag System 074. Airbags are
designed to inflate if the impact
exceeds the specific airbag system's
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. The vehicle
has electronic sensors that help the
airbag system determine the severity
of the impact. Deployment thresholds
can vary with specific vehicle design.
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 front outboard
passenger's head and chest.
Whether the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling.
It depends on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or moving,
rigid or deformable, narrow or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, in rear
impacts, or in many side impacts.
In addition, the vehicle has advanced
technology frontal airbags. Advanced
technology frontal airbags adjust the
restraint according to either crash
severity or occupant interaction.
Knee airbags are designed to inflate in
moderate to severe frontal or near
frontal impacts. Knee airbags are not
designed to inflate during vehicle
rollovers, in rear impacts, or in many
side impacts.
Seat-mounted side impact airbags are
designed to inflate in moderate to
severe side crashes depending on the
location of the impact. Seat-mounted
side impact airbags are not designed
to inflate in frontal impacts, near
frontal impacts, rollovers, or rear
impacts. A seat-mounted side impact
airbag is designed to inflate on the
side of the vehicle that is struck.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location of
the impact. In addition, these roof-rail
airbags are designed to inflate during
a rollover or in a severe frontal
impact. Roof-rail airbags are not
designed to inflate in rear impacts.

78 SEATS AND RESTRAINTS
Both roof-rail airbags will inflate when
either side of the vehicle is struck,
if the sensing system predicts that the
vehicle is about to roll over on its
side, or in a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the vehicle
damage or repair costs.
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. The inflator, the airbag, and
related hardware are all part of the
airbag module.
For airbag locations, seeWhere Are the
Airbags? 075.
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 by
distributing the force of the impact
more evenly over the occupant's 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? 077.
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 inflate. Some
components of the airbag module may
be hot for several minutes. For
location of the airbags, see Where Are
the Airbags? 075.
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.

84 SEATS AND RESTRAINTS
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly. The operation of the
airbag system can also be affected by
changing any parts of the front seats,
safety belts, the airbag sensing and
diagnostic module, steering wheel,
instrument panel, any of the airbag
modules, ceiling or pillar garnish trim,
front sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual
have information about the location of
the airbag sensors, sensing and
diagnostic module, and airbag wiring.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced with
non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Anyobject, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). See
Passenger Sensing
System 079.
The vehicle has rollover roof-rail
airbags. See Different Size Tires and
Wheels 0288 for additional important
information.
If your vehicle needs to be modified
because you have a disability and you
have questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, see
your dealer.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0126.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 075. See
your dealer for service.
