The driver knee airbag is below the
steering column. The front outboard
passenger knee airbag is below the
glove box.Driver Side Shown, Passenger SideSimilar
The seat-mounted side impact airbags
for the driver and front outboard
passenger are in the side of the
seatbacks closest to the door.
The roof-rail airbags for the driver,
front outboard passenger, and second
row outboard passengers 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 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.

SEATS AND RESTRAINTS 75
When Should an Airbag
Inflate?
This vehicle is equipped with airbags.
SeeAirbag System 072. 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 frontal 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 crash severity.
Knee airbags are designed to inflate in
moderate to severe frontal impacts.
Knee airbags are not designed to
inflate during vehicle rollovers, in rear
impacts, or in many side impacts.
The vehicle also has a seat position
sensor that enables the sensing
system to monitor the position of the
front outboard passenger seat. The
passenger seat position sensor and the
passenger seat belt buckle provide
information that is used to determine
if the passenger knee airbag should
inflate.
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.
Both roof-rail airbags will inflate when
either side of the vehicle is struck or 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.

12460272) - 2019 - crc - 5/8/18
76 SEATS AND RESTRAINTS
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? 073.
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 seat 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? 075.
Airbags should never be regarded as
anything more than a supplement to
seat belts.
What Will You See after an
Airbag Inflates?
After frontal, knee, and seat-mounted
side impact 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 inflate. Some components of the airbag module may
be hot for several minutes. For
location of the airbags, see
Where Are
the Airbags? 073.
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 (Continued)

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, seePublication Ordering
Information 0355.
{Warning
For up to 10 seconds after the
vehicle is turned off and the battery
is disconnected, an airbag can still
inflate during improper service. You
can be injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag system.
Be sure to follow proper service
procedures, and make sure the
person performing work for you is
qualified to do so.
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,
including improperly repairing or
replacing, any parts of the following:
.
Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
. Front seats, including stitching,
seams or zippers
. Seat belts
. Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
. Inner door seals, including
speakers
Your dealer and the service manual
have information about the location of
the airbag modules and sensors, sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
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. Any
object, 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 077.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0299 for additional important
information.
