Lap-Shoulder Belt
All seating positions in your vehicle have a lap-shoulder
except for the center front passenger position
(if equipped), which has a lap belt. SeeLap Belt on
page 1-29for more information.
Here is how to wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can
sit up straight. To see how, see “Seats” in the Index.
2. 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.
If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let the
belt go back all the way and start again.
Engaging the child restraint locking feature may
affect the passenger sensing system. See
Passenger Sensing System on page 1-63.3. Push the latch plate into the buckle until it clicks.
If you nd that the latch plate will not go fully into the
buckle, see if you are using the correct buckle.
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 necessary.
4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
“Shoulder Belt Height Adjustment” later in this
section.
1-24

To make the belt shorter, pull its free end as shown
until the belt is snug.
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 necessary.
If you nd that the latch plate will not go fully into the
buckle, see if you are using the correct buckle. Be sure
that the latch plate clicks when inserted into the buckle.
Safety Belt Extender
If the safety belt will fasten around you, you should
use it.
But if a safety belt is not long enough, your
dealer/retailer will order you an extender. 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, attach it to the
regular safety belt. For more information, see the
instruction sheet that comes with the extender.

{CAUTION:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a
child will become so heavy it is not possible to
hold it during a crash. For example, in a crash
at only 25 mph (40 km/h), a 12 lb (5.5 kg) infant
will suddenly become a 240 lb (110 kg) force
on a person’s arms. An infant should be
secured in an appropriate restraint.
1-35

{CAUTION:
Never do this.
Children who are up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Never put a rear-facing child
restraint in the right front seat. Secure a
rear-facing child restraint in a rear seat. It is
also better to secure a forward-facing child
restraint in a rear seat. If you must secure a
forward-facing child restraint in the right front
seat, always move the front passenger seat as
far back as it will go.
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.
1-36

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:
To reduce the risk of neck and head injury
during a crash, infants need complete support.
This is because an infant’s neck is not fully
developed and its head weighs so much
compared with the rest of its body. In a crash,
an infant in a rear-facing child restraint 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
should always be secured in rear-facing child
restraints.
{CAUTION:
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. To reduce the risk of
serious or fatal injuries during a crash, young
children should always be secured in
appropriate child restraints.
1-37

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. Secure the child restraint
properly in the vehicle using the vehicle’s safety
belt or LATCH system, following the
instructions that came with that child restraint
and 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.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 the vehicle — even when no child
is in it.
Securing the Child Within the Child
Restraint
{CAUTION:
A child can be seriously injured or killed in a
crash if the child is not properly secured in the
child restraint. Secure the child properly
following the instructions that came with that
child restraint.
1-39

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 recommend that children and child restraints be
secured in a rear seat, including: an infant or a child
riding in a rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large enough, using
safety belts.
A label on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. A child in a
CAUTION: (Continued)
CAUTION: (Continued)
forward-facing child restraint can be seriously
injured or killed if the right front passenger
airbag inates and the passenger seat is in a
forward position.
Even if the passenger sensing system has
turned off the right front passenger frontal
airbag, no system is fail-safe. No one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though it is
turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you 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.
SeePassenger Sensing System on page 1-63
for additional information.
