To return the seat(s) to the upright position, do the
following:
1. Lift the seatback up and push it rearward all
the way.
2. Lower the seat cushion until it latches into

Third Row Seat (SUV)
Entering or Exiting the Third Row Seat
If your vehicle has a third row seat, you must
fold the second row seat down before entering or
exiting the third row. See “Folding the Seatbacks”
under60/40 Split Bench Seat on page 15
earlier in this section for instructions.
The third row seatback can be folded and the
entire seat can be tilted or removed from
the vehicle.
Folding the Seatback
To fold the seatback, do the following:
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.
1. Pull up on the
release lever
labeled 1, located on
the rear of the
seatback, and push
the seatback
forward.
17

To install the seat, do the following:
1. While holding the rear of the seat up, slide the
front wheels into the slots on the oor. The
front latches should lock into place. If the
latches do not lock, try tilting the rear of the
seat upward.
2. Once the latches are engaged, pull up on
the lever labeled 3 to allow the seat to drop
into place.3. Pull up on the lever labeled 1 to return the
seatback to its upright position.
4. Push and pull on the seat to make sure it is
locked into place. The seatback cannot be
raised to the upright position unless the seat is
secured to the oor.

3. 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.
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,
seeSafety Belt Extender on page 45.Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the
safety belt through the latch plate to fully
tighten the lap belt on smaller occupants.
30

Lap-Shoulder Belt
All rear seat positions have lap-shoulder belts.
Here is how to wear one properly.
1. Pick up the latch plate and pull the belt across
you. Do not let it get twisted.
The 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.
2. Push the latch plate into the buckle until
it clicks.Pull up on the latch plate to make sure it
is secure.
When the shoulder belt is pulled out all the
way, it will lock. If it does, let it go back all the
way and start again.
If the belt is not long enough, seeSafety Belt
Extender on page 45.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
3. To make the lap part tight, pull up on the
shoulder part.
40

4. Buckle, position, and release the safety belt
as described inRear Seat Passengers on
page 39. Make sure that the shoulder
belt crosses the shoulder.
To remove and store the comfort guide, squeeze
the belt edges together so that you can take them
out of the guide. For the second row, slide the guide
onto its storage clip on the trim panel near the side
of the seatback. For the third row, slide the guide
onto its storage clip on the side of the seatback.
Make sure you remove the comfort guide from the
belt before you fold a rear seat down.
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
t. The extender has been designed for adults.
Never use it for securing child seats. To wear it,
just attach it to the regular safety belt. For
more information see the instruction sheet that
comes with the extender.

{CAUTION:
People should never hold a baby in their
arms while riding in a vehicle. A baby
does not weigh much — until a crash.
During a crash a baby 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) baby will
suddenly become a 240 lb (110 kg) force
on a person’s arms. A baby should be
secured in an appropriate restraint.

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 always should be
secured in appropriate infant restraints.
52

{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 always should be secured
in appropriate child restraints.
Child Restraint Systems
An infant car bed (A), a special bed made for use
in a motor vehicle, is an infant restraint system
designed to restrain or position a child on a
continuous at surface. Make sure that the infant’s
head rests toward the center of the vehicle.
53

A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.
Q:How Should I Use a Child Restraint?
A:A child restraint system is any device designed
for use in a motor vehicle to restrain, seat, or
position children. A built-in child restraint
system is a permanent part of the motor
vehicle. An add-on child restraint system is a
portable one, which is purchased by the
vehicle’s owner. To help reduce injuries, an
add-on child restraint must be secured in
the vehicle. With built-in or add-on child
restraints, the child has to be secured within
the child restraint.
When choosing an add-on child restraint, be
sure the child restraint is designed to be
used in a vehicle. If it is, it will have a label
saying that it meets federal motor vehicle
safety standards. Then follow the instructions
for the restraint. You may nd these
instructions on the restraint itself or in a
booklet, or both.
