Airbag System
Your vehicle has a frontal airbag for the driver and a
frontal airbag for the right front passenger. Your
vehicle may also have roof-mounted side impact
airbags. Roof-mounted side impact airbags are
available for the driver and the passenger seated
directly behind the driver and for the right front
passenger and the passenger seated directly
behind that passenger.
If your vehicle has roof-mounted side impact
airbags, the word AIRBAG will appear on
the airbag covering on the ceiling near the
side windows.
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.
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in

CAUTION: (Continued)
rollover, rear crashes, or in many side
crashes. And, for some unrestrained
occupants, frontal airbags may provide
less protection in frontal crashes than
more forceful airbags have provided in
the past.
Roof-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. Everyone in your vehicle should
wear a safety belt properly — whether or
not there is an airbag for that person.
{CAUTION:
Both frontal and side impact airbags
inate with great force, faster than the
blink of an eye. If you are too close to an
inating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag ination before and
during a crash. Always wear your safety
belt even with frontal 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.
67

The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.If your vehicle has a roof-mounted side impact
airbag for the driver and the person seated directly
behind the driver, it is located in the ceiling
above the side windows.
69

If your vehicle has a roof-mounted side impact
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.
70

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 may or may not have roof-mounted
side impact airbags. SeeAirbag System on
page 66. Roof-mounted side impact airbags are
intended to inate in moderate to severe side
crashes. A roof-mounted side impact 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
side impact airbags are not intended to inate in
frontal or near-frontal impacts, rollovers or rear
impacts. A roof-mounted side impact airbag is
intended to deploy on the side of the vehicle
that is struck.
72

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 side impact airbags,
ination is determined by the location and severity
of the impact.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is in a
crash. 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 side
impact airbags, there are also airbag modules 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. Side impact airbags would
not help you in many types of collisions, including
many frontal or near frontal collisions, rollovers,
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 for vehicles with side impact airbags.
73

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 the
airbag inated. Roof-mounted side impact 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, or the ceiling of your
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
turn on the hazard warning ashers when the
airbags inate. You can lock the doors again, turn
the interior lamps off, and turn the hazard warning
ashers off by using the controls for those features.
74

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height, front
end or side sheet metal, they may keep the
airbag system from working properly. Also, the
airbag system may not work properly if you
relocate any of the airbag sensors. If you have
any questions about this, you should contact
Customer Assistance before you modify your
vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction
Procedure on page 478.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the front
seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument
panel, ceiling headliner, ceiling and pillar
garnish trim, roof-mounted airbag modules,
or airbag wiring can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers
and addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 478.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. SeeCare of Safety Belts on page 442
for more information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers,
and have them repaired or replaced. The airbag
system does not need regular maintenance.
Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag, or
the side impact airbag covering (if equipped) on
the ceiling near the side windows, the airbag
may not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel for
the right front passenger’s airbag, or side
impact airbag module and ceiling covering for
roof-mounted side impact airbags (if equipped.)
Do not open or break the airbag coverings.
