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.
5. Pull up on the seatback until it locks into the
upright position.
{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.
6. Push and pull on the seatback to make sure it
is locked.
{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.
7. Make sure the safety belts are returned to the
original position over the seatbacks.
37

3. 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.
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, see
Safety Belt Extender on page 60.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. Move the shoulder belt height adjuster 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 on page 50.
6. To make the lap part tight, pull up on the
shoulder belt.
44

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 60.
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.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are located on the retractor
part of the safety belts. They help the safety
belts reduce a person’s forward movement in a
moderate to severe frontal, near frontal, rear
or side crash, or a rollover.
Pretensioners work only once. If they activate
in a crash, you will need to get new ones,
and probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 109.
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.
67

{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.
68

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.

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 74for 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 this manual. 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.
