Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is 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.
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.
Be sure to use the correct buckle when buckling
your lap-shoulder belt. If you nd that the latch plate
will not go fully into the buckle, see if you are
using the buckle for the center passenger position.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, seeSafety
Belt Extender on page 1-27.
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.

Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-27.
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 down on the buckle
end of the belt as you pull up on the shoulder part.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 pelvic bones. And you would 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.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the driver
and right front passenger. Although you can not see
them, they are located on the buckle end of the safety
belts. They help the safety belts reduce a person’s
forward movement in a moderate to severe frontal and
near frontal crash.
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 1-59.
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. It is free. 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.

Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints.
In fact, the law in every state in the United States and
in every Canadian province says children up to
some age must be restrained while in a vehicle.
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 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.
1-31

{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 is 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 seat, 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 airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Always secure a rear-facing child restraint in
a rear seat.
If you need to 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.
{CAUTION:
A child in a child restraint in the center front
seat can be badly injured or killed by the right
front passenger’s airbag if it inates. Never
secure a child restraint in the center front seat.
It is always better to secure a child restraint in
the rear seat.
If you need to secure a forward-facing child
restraint in the right front passenger 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.
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.
