Child Restraint Systems
A rear-facing infant seat (A) provides
restraint with the seating surface
against the back of the infant.
The harness system holds the infant
in place and, in a crash, acts to
keep the infant positioned in the
restraint.A forward-facing child seat (B)
provides restraint for the child’s body
with the harness.A booster seat (C) is a child
restraint designed to improve the t
of the vehicle’s safety belt system.
A booster seat can also help a child
to see out the window. (A) Rear-Facing Infant Seat

Seats and Restraint System 1-31

{CAUTION
Airbags inate with great force,
faster than the blink of an eye.
Anyone who is up against, or very
close to, any airbag when it
inates can be seriously injured or
killed. Do not sit unnecessarily
close to the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear your safety
belt, even with 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 or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{CAUTION
Children who are up against, or
very close to, any airbag when it
inates can be seriously injured or
killed. Airbags plus lap-shoulder
belts offer protection for adults
and older children, 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 1-25orInfants and Young
Children on page 1-28.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 3-25for
more information.
1-48 Seats and Restraint System

The roof-rail airbags for the driver,
right front passenger, and second
row outboard passengers are in the
ceiling above the side windows.
{CAUTION
If something is between an
occupant and an airbag, the
airbag 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.
Do not use seat accessories that
block the ination path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie down
through any door or window
opening. If you do, the path of an
inating roof-rail airbag will be
blocked.
When Should an Airbag
Inate?
Frontal airbags are designed to
inate in moderate to severe frontal
or near-frontal crashes to help
reduce the potential for severe
injuries mainly to the driver’s or right
front passenger’s head and chest.
However, they are only designed to
inate if the impact exceeds a
predetermined deployment
threshold. Deployment thresholds
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 the 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. Driver Side shown, Passenger
Side similar
1-50 Seats and Restraint System

determined by the location and
severity of the side impact. In a
rollover event, roof-rail airbag
deployment is determined by the
direction of the roll.
What Makes an Airbag
Inate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inator. Gas from the inator lls the
airbag causing the bag to break out
of the cover and deploy. The inator,
the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat-mounted side impact airbags,
there are airbag modules in the side
of the front seatbacks closest to
the door. For vehicles with roof-rail
airbags, there are airbag modules
in the ceiling of the vehicle, near the
side windows that have occupant
seating positions.
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.
Frontal airbags distribute the force of
the impact more evenly over the
occupant’s upper body, stopping the
occupant more gradually.
Seat-mounted side impact and
roof-rail airbags distribute the force of
the impact more evenly over the
occupant’s upper body.
Rollover capable roof-rail airbags are
designed to help contain the head
and chest of occupants in the
outboard seating positions in the
rst, second, and third rows. The
rollover capable roof-rail airbags are
designed to help reduce the risk offull or partial ejection in rollover
events, although no system can
prevent all such ejections.
But airbags would not help in many
types of collisions, primarily because
the occupant’s motion is not toward
those airbags. SeeWhen Should
an Airbag Inflate? on page 1-50
for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inates?
After the frontal airbags and
seat-mounted side impact airbags
inate, they quickly deate, so
quickly that some people may not
even realize an airbag inated.
Roof-rail airbags may still be at least
partially inated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, seeWhat Makes an
Airbag Inflate? on page 1-52.
1-52 Seats and Restraint System

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
(Continued)
CAUTION (Continued)
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.
The vehicle has a feature that may
automatically unlock the doors,
turn the interior lamps on, and turn
the hazard warning ashers on
when the airbags inate. You can
lock the doors, turn the interior
lamps off, and turn the hazard
warning ashers off by using the
controls for those features.
In many crashes severe enough to
inate the airbag, windshields are
broken by vehicle deformation.Additional windshield breakage may
also occur from the right front
passenger airbag.Airbags are designed to inate
only once. After an airbag inates,
you will need some new parts for
the airbag system. If you do not
get them, the airbag system will
not be there to help protect you
in another crash. A new system
will include airbag modules and
possibly other parts. The service
manual for your vehicle covers
the need to replace other parts.
The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
SeeVehicle Data Recording and
Privacy on page 7-16andEvent
Data Recorders on page 7-16.
Let only qualied technicians work
on the airbag systems. Improper
service can mean that an airbag
system will not work properly. See
your dealer/retailer for service.
