48 SEATS AND RESTRAINTS
When you wear a seat belt, you and
the vehicle slow down together. There
is more time to stop because you stop
over a longer distance and, when worn
properly, your strongest bones take
the forces from the seat belts. That is
why wearing seat belts makes such
good sense.
Questions and Answers About
Seat Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your
chance of being conscious during
and after a crash, so you can
unbuckle and get out, is much
greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems
only. They work withseat belts —
not instead of them. Whether or
not an airbag is provided, all
occupants still have to buckle up to
get the most protection. Also, in nearly all states and in all
Canadian provinces, the law
requires wearing seat belts.
How to Wear Seat Belts
Properly
Follow these rules for everyone's
protection.
There are additional things to know
about seat belts and children,
including smaller children and infants.
If a child will be riding in the vehicle,
see
Older Children 065 or
Infants and Young Children 067.
Review and follow the rules for
children in addition to the following
rules.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are wearing
seat belts.
There are important things to know
about wearing a seat belt properly.
.Sit up straight and always keep your
feet on the floor in front of you (if
possible).
.Always use the correct buckle for
your seating position.
.Wear the lap part of the belt low
and snug on the hips, just touching
the thighs. In a crash, this applies
force to the strong pelvic bones and
you would be less likely to slide
under the lap belt. If you slid under
it, the belt would apply force on
your abdomen. This could cause
serious or even fatal injuries.
.Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best

50 SEATS AND RESTRAINTS
Never route the lap or shoulder belt
over an armrest.
{Warning
The seat belt can be pinched if it is
routed under plastic trim on the
seat, such as trim around the rear
seatback folding handle or side
airbag. In a crash, pinched seat
belts might not be able to provide
adequate protection. Never allow
seat belts to be routed under plastic
trim pieces.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”in
the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it get
twisted. The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the belt
go back slightly to unlock it. Then
pull the belt across you more
slowly.
If the shoulder portion of a
passenger belt is pulled out all the
way, the child restraint locking
feature may be engaged. See
Child
Restraint Systems 069. If this
occurs, let the belt go back all the
way and start again. If the locking
feature stays engaged after letting
the belt go back to stowed position
on the seat, move the seat rearward
or recline the seat until the
shoulder belt retractor lock
releases.
Engaging the child restraint locking
feature in the front outboard
seating position may affect the
passenger sensing system. See
Passenger Sensing System 060.

54 SEATS AND RESTRAINTS
{Warning
Do not bleach or dye seat belt
webbing. It may severely weaken
the webbing. In a crash, they might
not be able to provide adequate
protection. Clean and rinse seat belt
webbing only with mild soap and
lukewarm water. Allow the webbing
to dry.
Replacing Seat Belt
System Parts after a Crash
{Warning
A crash can damage the seat belt
system in the vehicle. A damaged
seat belt system may not properly
protect the person using it,
resulting in serious injury or even
death in a crash. To help make sure
the seat belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.After a minor crash, replacement of
seat belts may not be necessary. But
the seat belt assemblies that were
used during any crash may have been
stressed or damaged. See your dealer
to have the seat belt assemblies
inspected or replaced.
New parts and repairs may be
necessary even if the seat belt system
was not being used at the time of the
crash.
Have the seat belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle or
while you are driving. See
Airbag
Readiness Light 0104.
Airbag System
The vehicle has the following airbags:
.A frontal airbag for the driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.
.A knee airbag for the front outboard
passenger.
.A seat-mounted side impact airbag
for the driver
.A seat-mounted side impact airbag
for the front outboard passenger
.A roof-rail airbag for the driver and
the passenger seated directly behind
the driver
.A roof-rail airbag for the front
outboard passenger and the
passenger seated directly behind the
front outboard passenger
All vehicle airbags have the word
AIRBAG on the trim or on a label near
the deployment opening.
For frontal airbags, the word AIRBAG
is on the center of the steering wheel
for the driver and on the instrument
panel for the front outboard
passenger.
For knee airbags, the word AIRBAG is
on the lower part of the instrument
panel.
For seat-mounted side impact airbags,
the word AIRBAG is on the side of the
seatback or side of the seat closest to
the door.
For roof-rail airbags, the word AIRBAG
is on the ceiling or trim.

SEATS AND RESTRAINTS 55
Airbags are designed to supplement
the protection provided by seat belts.
Even though today's airbags are also
designed to help reduce the risk of
injury from the force of an inflating
bag, all airbags must inflate very
quickly to do their job.
Here are the most important things to
know about the airbag system:
{Warning
You can be severely injured or
killed in a crash if you are not
wearing your seat belt, even with
airbags. Airbags are designed to
work with seat belts, not replace
them. Also, airbags are not designed
to inflate in every crash. In some
crashes seat belts are the only
restraint. SeeWhen Should an
Airbag Inflate? 057.
Wearing your seat 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
seat belts. Everyone in the vehicle (Continued)
Warning (Continued)
should wear a seat belt properly,
whether or not there is an airbag
for that person.
{Warning
Because airbags inflate with great
force and faster than the blink of an
eye, anyone who is up against,
or very close to, any airbag when it
inflates can be seriously injured or
killed. Do not sit unnecessarily
close to any airbag, as you would be
if sitting on the edge of the seat or
leaning forward. Seat belts help
keep you in position before and
during a crash. Always wear a seat
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle. The seat belts and the
front outboard passenger airbags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor.
(Continued)
Warning (Continued)
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.
{Warning
Children who are up against,
or very close to, any airbag when it
inflates can be seriously injured or
killed. Always secure children
properly in the vehicle. To read
how, seeOlder Children 065 or
Infants and Young Children 067.
There is an airbag readiness light on
the instrument 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 0104.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.
The front outboard passenger frontal
airbag is in the passenger side
instrument panel.
The driver knee airbag is below the
steering column. The front outboard
passenger knee airbag is below the
glove box.Driver Side Shown, Passenger Side

The roof-rail airbags for the driver,
front outboard passenger, and second
row outboard passengers are in the
ceiling above the side windows.
{Warning
If something is between an
occupant and an airbag, the airbag
might not inflate properly or it
might force the object into that
person causing severe injury or
even death. The path of an inflating
airbag must be kept clear. Do not (Continued)
Warning (Continued)
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 inflation 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 inflating roof-rail
airbag will be blocked.
When Should an Airbag
Inflate?
This vehicle is equipped with airbags.
SeeAirbag System 054. Airbags are
designed to inflate if the impact
exceeds the specific airbag system's
deployment threshold. Deployment
thresholds are used to predict how
severe a crash is likely to be in time
for the airbags to inflate and help restrain the occupants. The vehicle
has electronic sensors that help the
airbag system determine the severity
of the impact. Deployment thresholds
can vary with specific vehicle design.
Frontal airbags are designed to inflate
in moderate to severe frontal or near
frontal crashes to help reduce the
potential for severe injuries, mainly to
the driver's or front outboard
passenger's head and chest.
Whether the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling.
It depends on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or moving,
rigid or deformable, narrow or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or many side impacts.
