If you need to secure a forward-facing child
restraint in the right front seat position, move the
seat as far back as it will go before securing
the forward-facing child restraint. SeePower Seats
on page 9.
If your child restraint has the LATCH system,
seeLower Anchors and Tethers for Children
(LATCH) on page 74.
There is no top tether anchor at the right front
seating position. Do not secure a child seat in this
position if a national or local law requires that
the top tether be anchored or if the instructions
that come with the child restraint say that the top
tether must be anchored. SeeLower Anchors
and Tethers for Children (LATCH) on page 74if
the child restraint has a top tether.You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 101. We recommend that
rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the
child restraint in this seat. SeePower Seats
on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator on the passenger
airbag status indicator should light and stay
lit when you turn the ignition to RUN or
START. SeePassenger Airbag Status
Indicator on page 230.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.

4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.5. Pull the rest of the shoulder belt all the way
out of the retractor to set the lock.

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 a frontal airbag for the driver
and a frontal airbag for the right front passenger.
Your vehicle also has roof-mounted rollover
airbags designed for either side impact or rollover
deployment. Roof-mounted rollover 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.
For roof-mounted rollover airbags, the word
AIRBAG will appear on the airbag covering on the
ceiling above the sidewall trim near the driver’s
and right front passenger’s window and the
second row outside seating positions.
Also, if your vehicle has a third row passenger
seat, your vehicle will have third row roof-mounted
rollover airbags.
Frontal airbags are designed to help reduce
the risk of injury from the force of an inating
frontal airbag. But these airbags must inate 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)
90

Page 91 of 608

CAUTION: (Continued)
They are not designed 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 rollover
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 in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.
91

{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 61orInfants and Young Children on
page 64.
Occupants should not lean on or sleep
against the door in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.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 229for more information.

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 359for 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. 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.
If your vehicle has a third row seat with
roof-mounted rollover airbags, the airbag modules
are located inside the rear-most pillar trim and
above in the ceiling above the xed rear glass.

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 rollover 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 the airbag. 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 roof-mounted rollover airbags.

The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s airbag
should be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. 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 inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Be sure the airbag is off
before using a rear-facing child restraint
in the passenger’s position.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal 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 airbag is off.
CAUTION: (Continued)
102

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.
The passenger sensing system is designed to
enable (may inate) the right front passenger’s
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 airbag to be enabled, the
on indicator will light and stay lit to remind you
that the airbag is 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 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 theseat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the
vehicle and have the person remain in this position
for about two minutes. This will allow the system
to detect that person and then enable the
passenger’s airbag.
