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. Move the shoulder belt height adjuster to the height
that is right for you. SeeShoulder Belt Height
Adjustment on page 1-22.
6. To make the lap part tight, 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,
or if you pull the safety belt very quickly out of the
retractor.

Rear Seat Passengers
It is 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 are not 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.
Lap-Shoulder Belt
All rear seating 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.
The latch plates for the safety belts in each rear
seating position vary in size. If the center rear or the
left rear latch plate is inserted into the incorrect
buckle, the plate will not latch properly. Be sure you
are using the correct buckle and that the latch
plate clicks when inserted into the buckle.
When the shoulder belt is pulled out all the way,
it will lock. If it does, let it go back and start again.
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.
1-25

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.
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.

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.
1-33

{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 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.
Securing an Add-on Child Restraint
in the Vehicle
{CAUTION:
A child can be seriously injured or killed in a
crash if the child restraint is not properly
secured in the vehicle. Make sure the child
restraint is properly installed in the vehicle
using the vehicle’s safety belt or LATCH
system, following the instructions that came
with that restraint, and also the instructions in
this manual.
To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the
lap belt portion of a lap-shoulder belt, or by the LATCH
system. SeeLower Anchors and Tethers for Children
(LATCH) on page 1-41for more information. A child can
be endangered in a crash if the child restraint is not
properly secured in the vehicle.
1-38

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.
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.
Securing the Child Within the
Child Restraint
There are several systems for securing the child
within the child 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.
{CAUTION:
A child can be seriously injured or killed in a
crash if the child is not properly secured in the
child restraint. Make sure the child is properly
secured, following the instructions that came
with that restraint.
Because there are different systems, it is important to
refer to the instructions that come with the restraint.
A child can be endangered in a crash if the child is
not properly secured in the child restraint.
