levers are located on
the outboard side of
the rear seatbacks.
Pull the seatback toward you as you lift up on the lever.
The head restraint will automatically fold out of the
way when the seatback is folded down.
To raise the seatbacks, lift up the seatbacks and push
on them until they lock into the upright position.
Push and pull on the seatbacks to make sure that they
are latched securely. Then fold the bottom seat
cushion back into place.To return the head restraint to the upright position,
reach behind the seat and pull the restraint up until it
locks into place. Push and pull on the head restraint to
make sure that it is latched securely.

How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-26
orInfants and Young Children on page 1-28. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.
Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight.
To see how, see “Seats” in the Index.3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
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 isn’t long enough, seeSafety Belt
Extender on page 1-25.
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.

Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts.
Here’s how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
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, see
Safety Belt Extender on page 1-25.
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.

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 ve-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 at 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
nd 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.
We, therefore, recommend that child restraints be
secured in a rear outside seat position including an
infant riding in a rear-facing infant seat, a child riding
in a forward-facing child seat and an older child riding
in a booster seat.Neverput a rear-facing child restraint
in the front passenger seat. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag.
Always secure a rear-facing child restraint
in a rear seat outside position.
CAUTION: (Continued)
CAUTION: (Continued)
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 outside position.
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.
