3. Pull up on the release lever onthe back of the seat. The
headrest moves forward
automatically.
4. Push the seatback forward to lay flat.
Returning the Seat to the
Seating Position
To return the seatback to the
seating position:
1. From the rear of the vehicle,
raise the seatback to the upright
position using the pull strap on
the back of the third row seat, or lift the seatback and push it
into place from inside the
vehicle.
2. The headrest must be locked into place before sitting in
the seat.
{Warning
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
3. Push and pull on the seatback to make sure it is locked in place.
{Warning
A safety belt that is improperly
routed, not properly attached,
or twisted will not provide the
(Continued)
Warning (Continued)
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the safety belts are
properly routed and attached, and
are not twisted.
4. Reconnect the center safety belt mini-latch to the mini-buckle. Do
not let it twist.
5. Pull on the safety belt to be sure the mini-latch is secure.

3. Push the latch plate into thebuckle until it clicks.
4. 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 3-21.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
5. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster” later in this section for
instructions on use and
important safety information.
6. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull the
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position. Slide
the latch plate up the safety belt
webbing when the safety belt is not
in use. The latch plate should rest
on the stitching on the safety belt,
near the guide loop on the side wall.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.

To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Slide
the guide into its storage location or
on its storage clip.
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. Neveruse it for securing child seats. To
wear it, attach it to the regular safety
belt. See the instruction sheet that
comes with the extender.
Safety System Check
Now and then, check that 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
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. See
Safety Belt
Reminders on page 5-13.
Keep safety belts clean and dry.
See Safety Belt Care on page 3-22.

safety belts. Everyone in the
vehicle should wear a safety 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. Safety belts help keep
you in position before and during
a crash. Always wear a safety
belt, even with airbags. The driver(Continued)
Warning (Continued)
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the front center
armrest or console in vehicles
with a front center airbag.
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(Continued)

how, seeOlder Children on
page 3-36 orInfants and Young
Children on page 3-38.
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 on page 5-14 for
more information.

Do not use seat or console
accessories that block the
inflation path of a seat-mounted
side impact airbag or the front
center airbag, if equipped.
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 and Mexico
The words ON and OFF, or the
symbol 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
on page 5-15.
The passenger sensing system
turns off the front outboard
passenger frontal 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
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
the inflating airbag. A child in a

Warning (Continued)
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
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
inflate under some unusual
circumstance, even though the
airbag is 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 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 if:.The front outboard passenger
seat is unoccupied.
.The system determines that 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.
.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,
the off indicator will light and stay lit
as a reminder that the airbag is off.
See Passenger Airbag Status
Indicator on page 5-15.
The passenger sensing system is
designed to turn on the front
outboard passenger frontal 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 airbag to be
enabled, the on indicator will light
and stay lit as a reminder that the
airbag is 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, 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.

If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong

avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5-14 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 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 (Front
Passenger Seat) on page 3-53
orSecuring Child Restraints
(Rear Seat) on page 3-51.
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. The passenger sensing system
may or may not turn off the
airbag 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.

Seats and Restraints 3-39
Every time infants and young
children ride in vehicles, they should
have the protection provided by
appropriate child restraints. Neither
the vehicle's safety 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 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 right front
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 a forward-facing child
restraint must be secured in the(Continued)
Warning (Continued)
right front seat, always move the
front passenger seat as far back
as it will go.
If a child restraint is installed in
the second row center seat, move
the second row seat to the
rearward position, whenever
possible, to minimize contact with
the front center airbag,
if equipped.
