A forward-facing child seat (C-E) provides restraint
for the child’s body with the harness and also
sometimes with surfaces such as T-shaped
or shelf-like shields.A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.

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 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.
If your vehicle has 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, you may have third row roof-mounted rollover
airbags.
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)

Page 91 of 608
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 rollover 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. 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 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 in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof- mounted
rollover airbags.

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it in ates 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 227for more information.

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.

If your vehicle has a roof-mounted rollover airbag
and a third row passenger seat, the airbag is
located in the ceiling above the rear windows for
the outside passenger positions in the third row.
{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 rollover 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.

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 roof-mounted rollover
airbag, the sensing system detects that the
vehicle is about to roll over or has been in a severe
frontal or side impact. 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 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 impacts
and rollover events.
