{CAUTION:
If the 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 seatback to be sure it is
locked.
3. Push and pull on the seatback to make sure it is
locked in place.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
the 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.
Removing the Third Row Seats
1. Remove the cargo management system, if it is in
the vehicle. SeeCargo Management System on
page 2-59.
2. Remove anything on or under the seat.
Notice:Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
3. Fold the seatback down. See “Folding the Seatback”
earlier in this section.
4. Remove the rear bolts located on the oor on each
side of the seat.
5. Remove the seat by tilting it slightly upward, and
then pulling it out of the rear of the vehicle in one
motion.
6. Put the bolts back into the holes on the oor so
they do not get misplaced.

Lap-Shoulder Belt
All seating positions in your vehicle have a
lap-shoulder belt.
If you are using a rear seating position with a detachable
safety belt and the safety belt is not attached, see
Third Row Seats on page 1-13for instruction on
reconnecting the safety belt to the mini-buckle.
Here is 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 you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let the
belt go back all the way and start again.3. Push the latch plate into the buckle until it clicks.
4. Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-36.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
5. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash. See
“Shoulder Belt Height Adjustment” later in this
section.
1-30

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/retailer 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 t. The
extender has been designed for adults. Never use it for
securing child seats. To wear it, attach it to the
regular safety belt. For more information, see the
instruction sheet that comes with the extender.
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.

{CAUTION:
People should never hold an infant in their arms
while riding in a vehicle. An infant does not
weigh much — until a crash. During a crash an
infant will become so heavy it is not possible to
hold it. For example, in a crash at only 25 mph
(40 km/h), a 12 lb (5.5 kg) infant will suddenly
become a 240 lb (110 kg) force on a person’s
arms. An infant should be secured in an
appropriate restraint.
1-40

Q:What are the different types of add-on child
restraints?
A:Add-on child restraints, which are purchased by the
vehicle’s owner, are available in four basic types.
Selection of a particular restraint should take
into consideration not only the child’s weight, height,
and age but also whether or not the restraint will
be compatible with the motor vehicle in which it will
be used.
For most basic types of child restraints, 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.
{CAUTION:
Newborn infants need complete support,
including support for the head and neck. This
is necessary because a newborn infant’s neck
is weak and its head weighs so much
compared with the rest of its body. In a crash,
an infant in a rear-facing seat settles into the
restraint, so the crash forces can be
distributed across the strongest part of an
infant’s body, the back and shoulders. Infants
should always be secured in appropriate infant
restraints.
1-42

{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety 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. Young
children should always be secured in
appropriate child restraints.
Child Restraint Systems
A rear-facing infant
seat (A) provides restraint
with the seating surface
against the back of
the infant.
The harness system holds the infant in place and, in a
crash, acts to keep the infant positioned in the
restraint.
1-43

Securing an Add-On Child Restraint in
the Vehicle
{CAUTION:
A child can be seriously injured or killed in a
crash if the child restraint is not properly
secured in the vehicle. Make sure the child
restraint is properly installed in the vehicle
using the vehicle’s safety belt or LATCH
system, following the instructions that came
with that restraint, and also the instructions in
this manual.
To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the
lap belt portion of a lap-shoulder belt, or by the LATCH
system. SeeLower Anchors and Tethers for Children
(LATCH) on page 1-47for more information. A child can
be endangered in a crash if the child restraint is not
properly secured in the vehicle.
When securing an add-on child restraint, refer to the
instructions that come with the restraint which may be on
the restraint itself or in a booklet, or both, and to thismanual. The child restraint instructions are important, so
if they are not available, obtain a replacement copy
from the manufacturer.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people in
the vehicle. Be sure to properly secure any child restraint
in your vehicle — even when no child is in it.Securing the Child Within the Child
Restraint
{CAUTION:
A child can be seriously injured or killed in a
crash if the child is not properly secured in the
child restraint. Because there are different
systems, it is important to refer to the
instructions that come with the restraint. Make
sure the child is properly secured, following
the instructions that came with that restraint.
1-45

Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
We recommend that children and child restraints
be secured in a rear seat, including: an infant or a child
riding in a rear-facing child restraint; a child riding in
a forward-facing child seat; an older child riding in
a booster seat; and children, who are large enough,
using safety belts.
A label on your sun visor says, “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 deploys.{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag if the system detects a
rear-facing child restraint, no system is
fail-safe, and no one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though it is turned off. We
recommend that rear-facing child restraints be
secured 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 1-70
for additional information.
1-46

When securing a child restraint in a rear seating
position, study the instructions that came with your child
restraint to make sure it is compatible with this vehicle.
Wherever you install a child restraint, be sure to
secure the child restraint properly.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people in
the vehicle. Be sure to properly secure any child restraint
in your vehicle — even when no child is in it.
Lower Anchors and Tethers for
Children (LATCH)
The LATCH system holds a child restraint during driving
or in a crash. This system is designed to make
installation of a child restraint easier. The LATCH
system uses anchors in the vehicle and attachments on
the child restraint that are made for use with the
LATCH system.Make sure that a LATCH-compatible child restraint is
properly installed using the anchors, or use the vehicle’s
safety belts to secure the restraint, following the
instructions that came with that restraint, and also the
instructions in this manual. When installing a child
restraint with a top tether, you must also use either the
lower anchors or the safety belts to properly secure
the child restraint. A child restraint must never be
attached using only the top tether and anchor.
In order to use the LATCH system in your vehicle, you
need a child restraint that has LATCH attachments.
The child restraint manufacturer will provide you
with instructions on how to use the child restraint and its
attachments. The following explains how to attach a
child restraint with these attachments in your vehicle.
Not all vehicle seating positions or child restraints have
lower anchors and attachments or top tether anchors
and attachments.
