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
designed for either side impact or rollover deployment.
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 sidewall trim near the driver’s and right front
passenger’s window.
Frontal airbags are designed to help reduce the risk of
injury from the force of an in ating frontal airbag.
But these airbags must in ate very quickly to do their
job and comply with federal regulations.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.
CAUTION: (Continued)

CAUTION: (Continued)
They are not designed to in ate in 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 in ate in moderate to severe
crashes where something hits the side of your
vehicle. They are not designed to in ate in
frontal or in rear crashes. If the vehicle is
equipped with rollover capable airbags, it has
been designed to deploy the roof-mounted
side impact airbags in the event of a vehicle
rollover. Everyone in your vehicle should wear
a safety belt properly — whether or not there
is an airbag for that person.
{CAUTION:
Both frontal and roof-mounted side impact
airbags in ate with great force, faster than the
blink of an eye. If you are too close to an
in ating airbag, as you would be if you were
leaning forward, it could seriously injure you.
Safety belts help keep you in position for
airbag in ation 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.

If your vehicle has a roof-mounted airbag for the driver
and the person seated directly behind the driver, it
is located in the ceiling above the side windows.If your vehicle has a roof-mounted 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 in ate properly or it
might force the object into that person causing
severe injury or even death. The path of an
in ating 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 tiedown through any door
or window opening. If you do, the path of an
in ating side impact airbag will be blocked.
The path of an in ating airbag must be
kept clear.
When Should an Airbag In ate?
The driver’s and right front passenger’s frontal airbags
are designed to in ate in moderate to severe frontal or
near-frontal crashes. But they are designed to in ate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to in ate and help
restrain the occupants. Whether your frontal airbags will
or should deploy is not based on how fast your vehicle is
traveling. It depends largely on what you hit, the direction
of the impact and how quickly your vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors,
which help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For moderate frontal impacts, these airbags
in ate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs. If
the front of your vehicle goes straight into a wall
that does not move or deform, the threshold level for
the reduced deployment is about 9 to 16 mph (14
to 26 km/h), and the threshold level for a full deployment
is about 18 to 25 mph (29 to 40 km/h). (The threshold
level can vary, however, with speci c vehicle design, so
that it can be somewhat above or below this range.)

Frontal airbags may in ate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could in ate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could in ate 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 in ate 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 in ate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger) are
not intended to in ate during vehicle rollovers, rear
impacts, or in many side impacts.
Your vehicle has seat position sensors which enable the
sensing system to monitor the position of the driver’s
seat and the 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 may or may not have a roof-mounted
airbag and a rollover sensor. SeeAirbag System on
page 1-58. These “rollover capable” airbags are
intended to in ate in moderate to severe side crashes
or during a rollover. A roof-mounted airbag will in ate if
the crash severity is above the system’s designed
“threshold level.” The threshold level can vary with
speci c vehicle design. Roof-mounted airbags are not
intended to in ate in frontal or near-frontal impacts,
or rear impacts. Both roof-mounted airbags will deploy
when either side of the vehicle is struck or during
a rollover.
In any particular crash, no one can say whether an
airbag should have in ated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, in ation is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For roof-mounted
airbags, in ation is determined by the location and
severity of the impact.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving on page 4-19for tips on off-road driving.

What Makes an Airbag In ate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. In the case
of a “rollover capable” roof-mounted side impact
airbag, the sensing system detects that the vehicle is
about to roll over. The sensing system triggers a release
of gas from the in ator, which in ates the airbag. The
in ator, 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, the
airbag modules are located 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. The airbag supplements 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. Roof-mounted side impact
airbags would not help you in many types of collisions,
including many frontal or near frontal collisions, and
rear impacts, primarily because an occupant’s motion is
not toward those airbags. 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 or rollovers for the roof-mounted
side impact airbags.

What Will You See After an Airbag
In ates?
After a frontal airbag in ates, it quickly de ates, so
quickly that some people may not even realize
the airbag in ated. Roof-mounted side impact airbags
de ate more slowly and may still be at least partially
in ated minutes after the vehicle comes to rest. Some
components of the airbag module may be hot for a short
time. These components include the steering wheel
hub for the driver’s frontal airbag and the instrument
panel for the right front passenger’s frontal airbag. For
vehicles with side impact airbags, the ceiling of your
vehicle near the side windows may be hot. The parts of
the bag that come into contact with you may be
warm, but not too hot to touch. There will be some
smoke and dust coming from the vents in the de ated
airbags. Airbag in ation does not prevent the driver from
seeing out of the windshield or being able to steer the
vehicle, nor does it stop people from leaving the vehicle.
{CAUTION:
When an airbag in ates, there is 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
in ates, 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 and turn the interior lamps on when
the airbags in ate (if battery power is available). You can
lock the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.
