6. To tighten the belt, push down on the child
restraint, pull the shoulder portion of the belt
to tighten the lap portion of the belt and
feed the shoulder belt back into the retractor.
If you are using a forward-facing child
restraint, you may nd it helpful to use your
knee to push down on the child restraint
as you tighten the belt. You should not be able
to pull more of the belt from the retractor
once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.8. If the airbag is off, the off indicator will be
lit and stay lit when the key is turned to
RUN or START.
If a child restraint has been installed and the
on indicator is lit, turn the vehicle off. Remove
the child restraint from the vehicle and reinstall
the child restraint.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to
make sure that the vehicle’s seatback is not
pressing the child restraint into the seat cushion.
If this happens, slightly recline the vehicle’s
seatback and adjust the seat cushion if possible.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head 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.
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.

Airbag System
Your vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
Your vehicle may have the following airbags:
A roof-mounted rollover airbag for the driver
and right front passenger.
A roof-mounted rollover airbag for the second
row outboard passenger positions.
If your vehicle has roof-mounted rollover airbags,
the word AIRBAG will appear on the airbag
covering on the headliner above the sidewall trim
near the driver’s and right front passenger’s
window and the rear passenger’s outboard
seating positions.
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.
{CAUTION:
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
CAUTION: (Continued)
72

CAUTION: (Continued)
to inate 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 rollover airbags are
designed to inate 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 inate in rear crashes. If your
vehicle has roof-mounted airbags, they
are designed to provide both side impact
protection and rollover protection.
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.
73

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates can be
seriously injured or killed. 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 45orInfants and Young Children
on page 48.There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system
for malfunctions. The light tells you if there is
an electrical problem. SeeAirbag Readiness
Light on page 242for more information.
74

Where Are the Airbags?
The driver’s airbag is in the middle of the
steering wheel.The right front passenger’s airbag is in the
instrument panel on the passenger’s side.
75

If your vehicle has a roof-mounted rollover 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 rollover airbag
for the right front passenger and the person
directly behind that passenger, it is located in
the ceiling above the side windows.
76

{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.
77

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 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 a seat position sensor which
enables the sensing system to monitor the
fore and aft position of the driver’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
rollover airbags and a rollover sensor. See
Airbag System on page 72. These “rollover
capable” airbags are intended to inate in
moderate to severe side crashes, during a rollover,
or in a severe frontal impact. A roof-mounted
rollover 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 airbags are not intended
to inate in rear impacts. Both roof-mounted
rollover airbags will deploy when either side of
the vehicle is struck, during a rollover, or in
a severe frontal impact.
78

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 rollover airbags,
ination is determined by the location and
severity of the impact or a rollover event.
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 368for 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 severe
frontal impact or 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.
79

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.
