But if a seat belt is not long enough,
your dealer will order you an extender.
When you go in to order it, take the
heaviest coat you will wear, so the
extender will be long enough for you.
To help avoid personal injury, do not
let someone else use it, and use it
only for the seat it is made to fit. The
extender has been designed for adults.
Never use it for securing child
restraints. For more information on
the proper use and fit of seat belt
extenders see the instruction sheet
that comes with the extender.
Safety System Check
Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt height
adjusters (if equipped), and seat belt
anchorages to make sure they are all
in working order. Look for any other
loose or damaged seat belt system
parts that might keep a seat belt
system from performing properly. See
your dealer to have it repaired. Torn,
frayed, or twisted seat belts may not
protect you in a crash. Torn or frayed
seat belts can rip apart under impactforces. If a belt is torn or frayed, have
it replaced immediately. If a belt is
twisted, it may be possible to untwist
by reversing the latch plate on the
webbing. If the twist cannot be
corrected, ask your dealer to fix it.
Make sure the seat belt reminder light
is working. See
Seat Belt Reminders
0 128.
Keep seat belts clean and dry. See Seat
Belt Care 075.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for
and maintained.
Seat belt hardware should be kept dry
and free of dust or debris. As
necessary, exterior hard surfaces and
seat belt webbing may be lightly
cleaned with mild soap and water.
Ensure there is not excessive dust or
debris in the mechanism. If dust or
debris exists in the system please see
the dealer. Parts may need to be
replaced to ensure proper
functionality of the system.
{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.

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? 079.
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
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.
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, see Older Children 089 or
Infants and Young Children 090.
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. See
Airbag Readiness Light 0129.

person causing severe injury or
even death. The path of an inflating
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 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 076. Airbags are
designed to inflate if the impact
exceeds the specific airbag system's

The words ON and OFF, or the
symbols for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, or the symbol for on
or off will be visible. See Passenger
Airbag Status Indicator 0130.
The passenger sensing system turns
off the front outboard passenger
frontal airbag and knee airbag under
certain conditions. No other airbag is
affected by the passenger sensing
system.
The passenger sensing system works
with sensors that are part of the front
outboard passenger seat. The sensors
are designed to detect the presence of
a properly seated occupant and
determine if the front outboard passenger frontal airbag and knee
airbag should be allowed to inflate
or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
Whenever possible, children aged
12 and under should be secured in a
rear seating position.
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 inflates.
{Warning
A child in a rear-facing child
restraint can be seriously injured or
killed if the passenger frontal airbag
inflates. This is because the back of
the rear-facing child restraint would
be very close to the inflating airbag.
A child in a forward-facing child
restraint can be seriously injured or
(Continued)
Warning (Continued)
killed if the passenger frontal airbag
inflates and the passenger seat is in
a forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are off.
Never put a rear-facing child
restraint in the front seat, even if
the airbag is off. If securing a
forward-facing child restraint in the
front outboard passenger seat,
always move the seat as far back as
it will go. It is better to secure child
restraints in the rear seat. Consider
using another vehicle to transport
the child when a rear seat is not
available.

5. If, after reinstalling the child restraint and restarting the
vehicle, the ON indicator is still
lit, turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback is
not pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped under the
vehicle head restraint. If this
happens, adjust the head
restraint. See Head Restraints
0 53.
6. Restart the vehicle. The passenger sensing system
may or may not turn off the
airbags for a child in a child
restraint depending upon the
child’s size. It is better to secure the child restraint in a rear seat.
Consider using another vehicle to
transport the child when a rear
seat is not available. Never put a
rear-facing child restraint in the
front seat, even if the ON
indicator is not lit.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat, but
the OFF indicator is lit, it could be
because that person is not sitting
properly in the seat. Use the following
steps to allow the system to detect
that person and enable the front
outboard passenger frontal airbag and
knee airbag:
1. Turn the vehicle off.
2. Remove any additional material from the seat, such as blankets,
cushions, seat covers, seat
heaters, or seat massagers. Also
remove laptops, or other
electronic devices.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the person remain in this position
for two to three minutes after
the ON indicator is lit.{Warning

airbag is turned off for an
adult-sized occupant, the airbag will

Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible. If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See

{Warning
Children can be seriously injured or
strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor, but
it cannot do this if it is wrapped
around a child’s neck. If the
shoulder belt is locked and
tightened around a child’s neck, the
only way to loosen the belt is to
cut it.
Never leave children unattended in
a vehicle and never allow children
to play with the seat belts.Every time infants and young children
ride in vehicles, they should have the
protection provided by appropriate
child restraints. Neither the vehicle's
seat belt system nor its airbag system
is designed for them.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
{Warning
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb)
infant will suddenly become a
110 kg (240 lb) force on a person's
arms. An infant or child should be
secured in an appropriate restraint.{Warning
Children who are up against,
or very close to, any airbag when it
inflates can be seriously injured or
killed. Never put a rear-facing child
restraint in the front outboard seat.
Secure a rear-facing child restraint
in a rear seat. It is also better to
secure a forward-facing child
restraint in a rear seat. If you must
secure a forward-facing child
restraint in the front outboard seat,
always move the front passenger
seat as far back as it will go.

92 SEATS AND RESTRAINTS
Child restraints are devices used to
restrain, seat, or position children in
the vehicle and are sometimes called
child seats or car seats.
There are three basic types of child
restraints:
.Forward-facing child restraints
. Rear-facing child restraints
. Belt-positioning booster seats
The proper child restraint for your
child depends on their size, weight,
and age, and also on whether the
child restraint is compatible with the
vehicle in which it will be used. For each type of child restraint, there
are many different models available.
When purchasing a child restraint, be
sure it is designed to be used in a
motor vehicle. If it is, the restraint will
have a label saying that it meets
federal motor vehicle safety standards.
The restraint manufacturer's
instructions that come with the
restraint state the weight and height
limitations for a particular child
restraint. In addition, there are many
kinds of restraints available for
children with special needs.
{Warning
To reduce the risk of neck and head
injury in a crash, infants and
toddlers should be secured in a
rear-facing child restraint until age
two, or until they reach the
maximum height and weight limits
of their child restraint.
{Warning
A young child's hip bones are still
so small that the vehicle's regular
seat belt may not remain low on
the hip bones, as it should. Instead,
it may settle up around the child's
abdomen. In a crash, the belt would
apply force on a body area that is
unprotected by any bony structure.
This alone could cause serious or
fatal injuries. To reduce the risk of
serious or fatal injuries during a
crash, young children should always
be secured in appropriate child
restraints.
