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 isadjustable, 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, let the belt go
back all the way and start again.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, see
Safety
Belt Extender on page 3-15.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
in this section for instructions on
use and important safety
information.

7. Buckle and position the safetybelt as described previously in
this section. Make sure that the
shoulder belt crosses the
shoulder.
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide.
Un-hook the guide from the loop on
the seat. Store the guide in a
convenient place like the glove box
for the next time it is needed.
Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety 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 safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety 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 seats. To
wear it, attach it to the regular safety
belt. See the instruction sheet that
comes with the extender.

{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 on
page 3-30 orInfants and Young
Children on page 3-32.
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. See Airbag Readiness
Light on page 5-11 for more
information.
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, if equipped,
is below the steering column. The
front outboard passenger knee
airbag, if equipped, is below the
glove box.

If the vehicle has second row
seat‐mounted side impact airbags,
they are in the sides of the rear
seatback closest to the door.
{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 (Continued)
Warning (Continued)
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.

Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the instrument panel
when the vehicle is started.
United States
Canada
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. 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 on page 5-11.
The passenger sensing system
turns off the front outboard
passenger frontal airbag and knee
airbag (if equipped) 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 (if equipped)
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
age 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

Warning (Continued)
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
inflate under some unusual
circumstance, even though the
airbag(s) are off.
Secure rear-facing child restraints
in a rear seat, even if the
airbag(s) are off. If you secure 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 the child restraint in a
rear seat.The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag
and knee airbag (if equipped) if:
.The front outboard 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 front outboard passenger
takes his/her weight off of the
seat for a period of time.
.The front outboard passenger
seat is occupied by a smaller
person, such as a child who has
outgrown child restraints.
.There is a critical problem with
the airbag system or the
passenger sensing system.When the passenger sensing
system has turned off the front
outboard passenger frontal airbag
and knee airbag (if equipped), the
off indicator will light and stay lit as
a reminder that the airbags are off.
See
Passenger Airbag Status
Indicator on page 5-11.
The passenger sensing system is
designed to turn on the front
outboard passenger frontal airbag
and knee airbag (if equipped)
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 who have
outgrown 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 (if
equipped), 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.
{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 injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light on page 5-11 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 to
Securing Child Restraints (Rear
Seat) on page 3-44 orSecuring
Child Restraints (Right Front
Passenger Seat) on page 3-46.
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 on page 3-2.
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.
If the Off Indicator Is Lit for an
Adult-Size Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
