not let the belt twist.
4. Pull on the center seat belt to make sure the mini-latch is
secure.
5. Repeat the steps to raise the other seatback, if necessary.
When the seat is not in use, it should
be kept in the upright, locked position.Seat Belts
This section describes how to use seat
belts properly, and some things not
to do.
{Warning
Do not let anyone ride where a seat
belt cannot be worn properly. In a
crash, if you or your passenger(s)
are not wearing seat belts, injuries
can be much worse than if you are
wearing seat belts. You can be
seriously injured or killed by hitting
things inside the vehicle harder or
by being ejected from the vehicle.
In addition, anyone who is not
buckled up can strike other
passengers in the vehicle.
It is extremely dangerous to ride in
a cargo area, inside or outside of a
vehicle. In a collision, passengers
riding in these areas are more likely
to be seriously injured or killed. Do (Continued)
Warning (Continued)
not allow passengers to ride in any
area of the vehicle that is not
equipped with seats and seat belts.
Always wear a seat belt, and check
that all passenger(s) are restrained
properly too.
This vehicle has indicators as a
reminder to buckle the seat belts. See
Seat Belt Reminders 097.

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.
SeeChild Restraint Systems 067.
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 057.
If the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.
4. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Seat Belt
Extender 050.
Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.
5. To make the lap part tight, pull up on the shoulder belt.

Seat Belt Use During
Pregnancy
Seat belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to be
seriously injured if they do not wear
seat belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion
should be worn as low as possible,
below the rounding, throughout the
pregnancy.
The best way to protect the fetus is to
protect the mother. When a seat belt
is worn properly, it is more likely thatthe fetus will not be hurt in a crash.
For pregnant women, as for anyone,
the key to making seat belts effective
is wearing them properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.
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 allin 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 impact
forces. 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

Keep seat belts clean and dry. See Seat
Belt Care 050.
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

{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 063 or
Infants and Young Children 065.
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 098.
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.

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 051. Airbags are
designed to inflate if the impact
exceeds the specific airbag system's
deployment threshold. Deployment
thresholds are used to predict how

The passenger sensing system works
with sensors that are part of the front
outboard passenger seat and seat belt.
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(Continued)
Warning (Continued)
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
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
(Continued)
Warning (Continued)
using another vehicle to transport
the child when a rear seat is not
available.
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag and
knee airbag if:
. The front outboard passenger seat
is unoccupied.
. The system determines an infant
is present in a child restraint.
. A front outboard passenger takes
his/her weight off of the seat for a
period of time.
When the passenger sensing system
has turned off the front outboard
passenger frontal airbag and knee
airbag, the OFF indicator will light and
stay lit as a reminder that the airbags
are off. See Passenger Airbag Status
Indicator 099.
The passenger sensing system is
designed to turn on the front
outboard passenger frontal airbag and

knee airbag, anytime the system
senses that a person of adult size is
sitting properly in the front outboard
passenger seat.
When the passenger sensing system
has allowed the airbags to be enabled,
the ON indicator will light and stay lit
as a reminder that the airbags are
active.
For some children, including children
in child restraints, and for very small
adults, the passenger sensing system
may or may not turn off the front
outboard passenger frontal airbag and
knee airbag, depending upon the
person's seating posture and body
build. Everyone in the vehicle who has
outgrown child restraints should wear
a seat belt properly—whether or not
there is an airbag for that person.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
(Continued)
Warning (Continued)
injury to yourself or others, have
the vehicle serviced right away. See
Airbag Readiness Light098 for more
information, including important
safety information.
If the On Indicator Is Lit for a
Child Restraint
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag and
knee airbag, if the system determines
that an infant is present in a child
restraint. If a child restraint has been
installed and the ON indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions provided
by the child restraint manufacturer and refer to
Securing Child Restraints (With the
Seat Belt in the Front Seat)
078
or
Securing Child Restraints (With the
Seat Belt in the Rear Seat) 076.
Make sure the seat belt retractor
is locked by pulling the shoulder
belt all the way out of the
retractor when installing the
child restraint, even if the child
restraint is equipped with a seat
belt lock off. When the retractor
lock is set, the belt can be
tightened but not pulled out of
the retractor.
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. SeeHead Restraints
0 34.
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. 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 or that the child
restraint locking feature is engaged.
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.
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. If the shoulder portion of the belt is pulled out all the way, the
child restraint locking feature
will be engaged. This may
unintentionally cause the
passenger sensing system to turn
the airbag off for some adult-sized occupants. If this
happens, unbuckle the belt, let
the belt go back all the way, and
then buckle the belt again
without pulling the belt out all
the way.
6. Restart the vehicle and have the person remain in this position
for two to three minutes after the
ON indicator is lit.
{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag will
not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
serious injury or even death. An
adult-sized occupant should not
ride in the front outboard passenger
seat, if the passenger airbag OFF
indicator is lit.
