Airbag System
Your vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
A seat-mounted side impact airbag for the driver.
A seat-mounted side impact airbag for the right front
passenger.
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the passenger seated directly behind the right
front passenger.
All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With seat-mounted side impact airbags, the word
AIRBAG will appear on the side of the seatback closest
to the door.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.Airbags are designed to supplement the protection
provided by safety belts. Even though today’s airbags
are also designed to help reduce the risk of injury
from the force of an inating bag, all airbags must
inate very quickly to do their job.
Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety 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 safety belts. All airbags are
designed to work with safety belts, but do not
replace them.
1-56

{CAUTION:
Frontal airbags are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear crashes, or in many side crashes.
Seat-mounted side impact airbags are
designed to inate in moderate to severe
crashes where something hits the side of
your vehicle. They are not designed to inate
in frontal, in rollover, or in rear crashes.
Roof-rail airbags are designed to inate in
moderate to severe crashes where something
hits the side of your vehicle or in a severe
frontal impact. They are not designed to inate
in rollover or rear crashes.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an
airbag for that person.
{CAUTION:
Airbags inate with great force, faster than the
blink of an eye. Anyone who is up against, or
very close to, any airbag when it inates can
be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you
would be if you were sitting on the edge of
your seat or leaning forward. Safety belts help
keep you in position before and during a
crash. Always wear your safety belt, even with
airbags. The driver should sit as far back as
possible while still maintaining control of the
vehicle.
Occupants should not lean on or sleep against
the door or side windows in seating positions
with seat-mounted side impact airbags and/or
roof-rail airbags.
1-57

The roof-rail airbags for the driver, right front passenger,
and second row outboard passengers are in the
ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the airbag 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.
Do not use seat accessories that block the
ination 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 inating roof-rail
airbag will be blocked. Driver Side shown, Passenger Side similar
1-60

In addition, your vehicle has a dual-stage driver airbag.
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 inate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Your vehicle also has a dual-depth passenger airbag
that adjusts the restraint according to crash severity, seat
location, and safety belt status using electronic frontal
sensors and other special sensors which enable the
sensing system to monitor the position of the front
passenger seat. The passenger airbag inates to a
reduced depth when the passenger seat is in a forward
position. For more rearward front seating positions, the
passenger airbag may inate to an increased depth (a full
deployment), based on the crash severity measured early
in the event. (Always wear your safety belt, even with
frontal airbags.)
Your vehicle has seat position sensors which enables
the sensing system to monitor the position of the driver’s
and 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 has seat-mounted side impact and roof-rail
airbags. SeeAirbag System on page 1-56. Seat-mounted
side impact and roof-rail airbags are intended to inate
in moderate to severe side crashes. In addition, these
roof-rail airbags are intended to inate in a severe frontal
impact. Seat-mounted side impact and roof-rail airbags
will inate if the crash severity is above the system’s
designed threshold level. The threshold level can vary
with specic vehicle design.
Seat-mounted side impact airbags are not intended to
inate in frontal impacts, near-frontal impacts, rollovers,
or rear impacts. Roof-rail airbags are not intended to
inate in rollovers or rear impacts. A seat-mounted side
impact airbag is intended to deploy on the side of
the vehicle that is struck. Both roof-rail airbags will
deploy when either side of the vehicle is struck or in
a severe frontal impact.
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 seat-mounted side impact
and roof-rail airbags, deployment is determined by the
location and severity of the side impact.
1-62

What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inator. Gas from the inator lls the airbag causing the
bag to break out of the cover and deploy. The inator, 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 seat-mounted side impact airbags, there are
airbag modules in the side of the front seatbacks
closest to the door. 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. Seat-mounted side impact
and 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 Inflate? on
page 1-61for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
1-63

What Will You See After an Airbag
Inates?
After the frontal airbags and seat-mounted side impact
airbags inate, they quickly deate, so quickly that
some people may not even realize an airbag inated.
Roof-rail airbags may still be at least partially inated
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 Inflate? on page 1-63.
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.
The vehicle has a feature that may automatically unlock
the doors, turn the interior lamps on, and turn the hazard
warning ashers on when the airbags inate. You can
lock the doors, turn the interior lamps off, and turn the
hazard warning ashers off by using the controls for
those features.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-17.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an airbag
when it inates. 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
qualied to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
