Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the
driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.
.A knee airbag for the front
outboard passenger.
.A seat-mounted side impact
airbag for the driver
.A seat-mounted side impact
airbag for the front outboard
passenger
.A roof-rail airbag for the
driver and the passenger
seated directly behind the
driver
.A roof-rail airbag for the
front outboard passenger
and the passenger seated
directly behind the front
outboard passenger All vehicle airbags have the
word AIRBAG on the trim or
on a label near the deployment
opening.
For frontal airbags, the word
AIRBAG is on the center of the
steering wheel for the driver
and on the instrument panel
for the front outboard
passenger.
For knee airbags, the word
AIRBAG is on the lower part of
the instrument panel.
For seat-mounted side impact
airbags, the word AIRBAG is
on the side of the seatback or
side of the seat closest to
the door.
For roof-rail airbags, the word
AIRBAG is on the ceiling
or trim.
Airbags are designed to
supplement the protection
provided by seat belts. Even
though today's airbags are
also designed to help reduce
the risk of injury from the
force of an inflating bag, all
airbags must inflate very
quickly to do their job.
Here are the most important
things to know about the
airbag system:
{Warning
You can be severely injured
or killed in a crash if you are
not wearing your seat belt,
even with airbags. Airbags
are designed to work with
seat belts, not replace them.
Also, airbags are not
designed to inflate in every
crash. In some crashes seat
belts are the only restraint.
See When Should an Airbag
Inflate?
062.
Wearing your seat belt
during a crash helps reduce
your chance of hitting things
inside the vehicle or being
ejected from it. Airbags are
“supplemental restraints” to
the seat belts. Everyone in

Where Are the
Airbags?
The driver frontal airbag is in
the center of the steering
wheel.
The front outboard passenger
frontal airbag is in the
passenger side instrument
panel.
The driver knee airbag is
below the steering column.
The front outboard passenger
knee airbag is below the
glove box.Driver Side Shown,

The driver and front outboard
passenger seat-mounted side
impact airbags 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 (Continued)
Warning (Continued)
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.
When Should an
Airbag Inflate?
This vehicle is equipped with
airbags. See Airbag System
059. 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 crashes to help
reduce the potential for
severe injuries, mainly to the
driver's or front outboard
passenger's head and chest.

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?
062.
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? 061. 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

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

roof-rail airbags, see Different
Size Tires and Wheels

for additional important
information.
If the vehicle must be modified
because you have a disability
and 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, call
Customer Assistance. See
Customer Assistance Offices
0 485.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 0116.
