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 1-29
orInfants and Young Children on page 1-31. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
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 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, seeSafety Belt
Extender on page 1-28.
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 seat 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.
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 1-28.
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.

{CAUTION:
A safety belt that is not properly worn may not
provide the protection needed in a crash. The
person wearing the belt could be seriously
injured. 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.4. Buckle, position, and release the safety belt as
described inRear Seat Passengers on page 1-24.
Make sure that the shoulder belt crosses the
shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out of the
guides. Slide the guide onto the storage clip. Be sure
to remove the comfort guide from the belt before folding
the seat.
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.

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.

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.
1-34

{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.

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.
