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 ªSeatsº 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, see ªSafety Belt
Extenderº at the end of this section.
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.

CAUTION:
Anyone who is up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. Air bags plus lap
-shoulder belts offer
the best protection for adults, but not for young
children and infants. Neither the vehicle's safety
belt system nor its air bag system is designed for
them. Young children and infants need the
protection that a child restraint system can
provide. Always secure children properly in your
vehicle. To read how, see the part of this manual
called ªChildren.º
There is an air bag
readiness light on the
instrument panel,
which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.

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 ªSafety Belt
Extenderº at the end of this section.
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.

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.

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.

1-57
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.
Restraint Systems for Children
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 flat surface.
Make sure that the infant's head rests toward the center
of the vehicle.
