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 1-30.
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 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.
The safety belt locks if there is a sudden stop or crash.

Rear Seat Passengers
It’s very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in the
rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who aren’t safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
The positions next to the windows have
lap-shoulder belts.
Lap-Shoulder Belt
Here is how to wear a lap-shoulder belt properly.1. Pick up the latch plate and pull the belt across you.
Do not 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
you will engage the child restraint locking feature. If
this happens, just let the belt go back all the way
and start again.
If the belt is not long enough, seeSafety Belt
Extender on page 1-30.
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.

4. Buckle, position and release the safety belt as
described inRear Seat Passengers on page 1-25.
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.
Safety Belt Pretensioners
Your vehicle may have safety belt pretensioners. If it
does, they are located on the buckle end of the safety
belts for the driver and right front passenger. 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 1-71.
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.

{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.
{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.
