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, passenger
directly behind the driver, and the third
row outboard passenger position.
A roof-rail airbag for the right front passenger,
passenger directly behind the right front
passenger, and the third row outboard
passenger position.
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 in ating bag, all
airbags must in ate 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.
CAUTION: (Continued)

CAUTION: (Continued)
Airbags are “supplemental restraints” to
the safety belts. All airbags are designed
to work with safety belts, but do not
replace them.
{CAUTION:
Frontal airbags are designed to deploy in
moderate to severe frontal and near
frontal crashes. They are not designed to
in ate in rollover, rear crashes, or in many
side crashes.
Seat-mounted side impact airbags are
designed to in ate in moderate to severe
crashes where something hits the side of
your vehicle. They are not designed to
in ate in frontal, in rollover, or in rear
CAUTION: (Continued)
CAUTION: (Continued)
crashes. Rollover capable roof-rail airbags
are designed to in ate in moderate to
severe crashes where something hits the
side of your vehicle, during a vehicle
rollover, or in a severe frontal impact.
They are not designed to in ate in rear
crashes.
Everyone in your vehicle should wear a
safety belt properly — whether or not
there is an airbag for that person.

{CAUTION:
Airbags in ate with great force, faster
than the blink of an eye. Anyone who is
up against, or very close to, any airbag
when it in ates 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.
{CAUTION:
Airbags plus lap-shoulder belts offer the
best protection for adults, but not for
young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young
children and infants need the protection
that a child restraint system can provide.
Always secure children properly in your
vehicle. To read how, seeOlder Children
on page 48orInfants and Young Children
on page 51.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.

What Makes an Airbag In ate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas
from the in ator. Gas from the in ator lls
the airbag causing the bag to break out of the
cover and deploy. The in ator, 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.
Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants
in the outboard seating positions in the rst,
second, and third 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. SeeWhen Should
an Airbag Inflate? on page 81for more information.
Airbags should never be regarded as anything
more than a supplement to safety belts.

The passenger sensing system will turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver’s airbags are not part of the
passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger’s frontal
airbag and seat-mounted side impact airbag
should be enabled (may in ate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the
front seat.
We recommend that children be secured in a rear
seat, including: an infant or a child riding in a
rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large
enough, using safety belts.
A label on your sun visor says, “Never put a
rear-facing child seat in the front.” This is because
the risk to the rear-facing child is so great, if the
airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag in ates. This is
because the back of the rear-facing child
restraint would be very close to the
in ating airbag.
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal and
seat-mounted side impact airbag if the
system detects a rear-facing child
restraint, no system is fail-safe, and no
one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We
recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbags are off.
CAUTION: (Continued)

Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. SeeHead Restraints
on page 17.
Remove any additional material from the seat
cushion before reinstalling or securing the
child restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle,
and check with your dealer/retailer.
The passenger sensing system is designed to
enable (may in ate) the right front passenger’s
frontal airbag and seat-mounted side impact airbag
anytime the system senses that a person of
adult size is sitting properly in the right front
passenger’s seat. When the passenger sensing
system has allowed the airbags to be enabled, the
on indicator will light and stay lit to remind you
that the airbags are active.For some children who have outgrown child
restraints and for very small adults, the passenger
sensing system may or may not turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag, depending
upon the person’s seating posture and body build.
Everyone in your vehicle who has outgrown
child restraints should wear a safety belt
properly — whether or not there is an airbag for
that person.
If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it
could be because that person is not sitting properly
in the seat. If this happens, turn the vehicle off
and ask the person to place the seatback in
the fully upright position, then sit upright in the
seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the
vehicle and have the person remain in this position
for two to three minutes. This will allow the
system to detect that person and then enable the
right front passenger’s frontal airbag and
seat-mounted side impact airbag.

Safety belts help keep the passenger in position
on the seat during vehicle maneuvers and braking,
which helps the passenger sensing system
maintain the passenger airbag status. See “Safety
Belts” and “Child Restraints” in the Index for
additional information about the importance of
proper restraint use.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system. If
this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the airbag(s). SeeAirbag
Readiness Light on page 217for more on
this, including important safety
information.
A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the
exterior 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. See Customer
Satisfaction Procedure.
If your vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on
page 452for additional important information.
Q:Because I have a disability, I have to get
my vehicle modi ed. 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, roof-rail airbag modules,
ceiling headliner, and pillar garnish trim, side
impact sensors, rollover sensor module,
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 518.
Your dealer/retailer and the service manual have
information about the location of the airbag
sensors, sensing and diagnostic module and
airbag wiring.
