3. Fold the rear seatback forward and down.
{CAUTION:
If the seatback isn’t locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted won’t 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.To return the seatback to the upright position, do the
following:
1. Lift up the seatback and push it to its original
position. Ensure that the safety belts are not twisted
or caught under the seat cushion.
2. Push down firmly on the top of the seatback until it
latches securely in the fully upright position.
Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Don’t let anyone ride where he or she can’t
wear a safety belt properly. If you are in a
crash and you’re not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
CAUTION: (Continued)

4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
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 down on the buckle
end of the belt as you pull up on the shoulder belt.The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you’d be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of
the body are best able to take belt restraining forces.
The safety belt locks if there’s a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.

Lap-Shoulder Belt
All rear seating 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.
If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle it.
Pull up on the latch plate to make sure it is secure.
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.

Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
{CAUTION:
People should never hold a baby in their
arms while riding in a vehicle. A baby doesn’t
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.

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.
{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’s unprotected by any bony structure.
This alone could cause serious or fatal
injuries. Young children always should be
secured in appropriate child restraints.

Q:How do child restraints work?
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.
For many years, add-on child restraints have
used the adult belt system in the vehicle. To help
reduce the chance of injury, the child also has to
be secured within the restraint. The vehicle’s
belt system secures the add-on child restraint in
the vehicle, and the add-on child restraint’s harness
system holds the child in place within the restraint.
One system, the three-point harness, has straps that
come down over each of the infant’s shoulders and
buckle together at the crotch. The five-point harness
system has two shoulder straps, two hip straps and
a crotch strap. A shield may take the place of hip
straps. A T-shaped shield has shoulder straps that
are attached to a flat pad which rests low against the
child’s body. A shelf- or armrest-type shield has
straps that are attached to a wide, shelf-like shield
that swings up or to the side.When choosing a 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
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system
or the LATCH system in your vehicle, but the child also
has to be secured within the restraint to help reduce
the chance of personal injury. 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.

Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
In addition, the only seats in the vehicle that are designed
to accommodate a child restraint are the rear outboard
seating positions. Do not install a child restraint in the
front passenger’s seat and/or the rear center seating
position. The child restraint will not fit properly.
Wherever you install it, 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.
Top Strap
Some child restraints have a top strap, or “top tether.”
It can help restrain the child restraint during a collision.
For it to work, a top strap must be properly anchored
to the vehicle. Some top strap-equipped child restraints
are designed for use with or without the top strap
being anchored. Others require the top strap always
to be anchored. Be sure to read and follow the
instructions for your child restraint. If yours requires
that the top strap be anchored, don’t use the restraint
unless it is anchored properly.
If the child restraint does not have a top strap, one
can be obtained, in kit form, for many child restraints.
Ask the child restraint manufacturer whether or not a
kit is available.
