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.
To remove the child restraint, just unbuckle the
vehicle’s safety belt and let it go back all the
way. The safety belt will move freely again and
be ready to work for an adult or larger child
passenger. When the safety belt is not in use,
slide the latch plate up the safety belt webbing.
The latch plate should rest on the stitching on
the safety belt, near the guide loop on the
side wall.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 words AIR BAG will appear on the
airbag covering on the sidewall trim near the
driver’s and right front passenger’s window.
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.
65

CAUTION: (Continued)
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 or in rear crashes.
If the vehicle has 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 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

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.
70

{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.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate
to severe frontal or near-frontal crashes. But
they are designed to inate 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 inate
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 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, these airbags inate at a level
less than full deployment. For more severe
frontal impacts, full deployment occurs.
71

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 11 to
18 mph (17.5 to 28.9 km/h), and the threshold
level for a full deployment is about 18 to 23 mph
(28.9 to 37 km/h). The threshold level can
vary, however, with specic vehicle design, so that
it can be somewhat above or below this range.
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 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 roof-mounted
side impact airbags and a rollover sensor.
SeeAirbag System on page 65. These “rollover
capable” airbags are intended to inate in
moderate to severe side crashes or during a
rollover. 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 rear impacts. Both
roof-mounted rollover airbags will deploy when
either side of the vehicle is struck or during
a rollover.
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.
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 250for tips on
off-road driving.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is in a
crash. In the case of a roof-mounted rollover airbag,
the sensing system detects that the vehicle is about
to roll over or has been in a moderate to severe
side impact. 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 rollover
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.
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.
Roof-mounted rollover airbags would not help
you in many types of collisions, including many
frontal or near frontal collisions, and rear impacts.
73

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 vehicles with roof-mounted rollover airbags.
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
an airbag inated. Roof-mounted rollover 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, and the area along
the ceiling of the 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.
