Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
except for the center front passenger position
(if equipped), which has a lap belt. SeeLap Belt
on page 1-33for more information.
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. If this happens, just let the belt go
back all the way and start again.
Engaging the child restraint locking feature in the
right front seating position may affect the passenger
sensing system. SeePassenger Sensing System
on page 1-67for more information.3. Push the latch plate into the buckle until it clicks.
If the latch plate will not go fully into the buckle,
check if the correct buckle is being used.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-34.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
1-27

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inates. This is because the back of the
rear-facing child restraint would be very close to the
inating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though it is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint in
a rear seat.
SeePassenger Sensing System on page 1-67for
additional information.If the child restraint has the LATCH system, seeLower
Anchors and Tethers for Children (LATCH) on page 1-45
for how and where to install the child restraint using
LATCH. If a child restraint is secured using a safety belt
and it uses a top tether, seeLower Anchors and Tethers
for Children (LATCH) on page 1-45for top tether anchor
locations.
Do not secure a child seat in a position without a top
tether anchor if a national or local law requires that the
top tether be anchored, or if the instructions that come
with the child restraint say that the top strap must be
anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
When the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag, the off indicator
on the passenger airbag status indicator should
light and stay lit when you start the vehicle.
SeePassenger Airbag Status Indicator on
page 3-37.
1-55

{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 1-35or
Infants and Young Children on page 1-38.
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 3-36
for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-60

The passenger sensing system is designed to turn off
the right front passenger airbag and seat-mounted
side impact airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is present in
a rear-facing infant seat.
The system determines that a small child is present
in a child restraint.
The system determines that a small child is present
in a booster seat.
A right front passenger takes his/her weight off of
the seat for a period of time.
The right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag and seat-mounted
side impact airbag, the off indicator will light and stay lit
to remind you that the airbags are off. SeePassenger
Airbag Status Indicator on page 3-37.The passenger sensing system is designed to turn on
(may inate) the right front passenger frontal airbag and
seat-mounted side impact airbag anytime the system
senses that a person of adult size is sitting properly in
the right front passenger seat.
When the passenger sensing system has allowed the
airbags to be enabled, the on indicator will light and stay
lit to remind you that the airbags are active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger frontal
airbag and seat-mounted side impact airbag, depending
upon the person’s seating posture and body build.
Everyone in the vehicle who has outgrown child restraints
should wear a safety belt properly — whether or not there
is an airbag for that person.{CAUTION:
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 injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-36
for more information, including important safety
information.

If the On Indicator is Lit for 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 toSecuring a Child Restraint in the Right Front
Seat Position on page 1-54.5. 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
on page 1-2.
6. Restart the vehicle.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle,
and check with your dealer/retailer.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired. Torn
or frayed safety belts may not protect you in a crash.
They can rip apart under impact forces. If a belt is torn
or frayed, get a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-35for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-95.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-36for more information.
Notice:If an airbag covering is damaged, opened,
or broken, the airbag may not work properly.
Do not open or break the airbag coverings. If there
are any opened or broken airbag covers, have
the airbag covering and/or airbag module replaced.
For the location of the airbag modules, seeWhat
Makes an Airbag Inflate? on page 1-65. See
your dealer/retailer for service.
