Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
except for the center front passenger position
(if equipped), which has a lap belt. SeeLap Belt
on page 1-31for more information.
The following instructions explain 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 the shoulder portion of a passenger belt out all
the way, the child restraint locking feature may
be engaged. If this happens, let the belt go back
all the way and start again.
Engaging the child restraint locking feature in the
right front seating position may affect the passenger
sensing system. SeePassenger Sensing System
on page 1-64for more information.3. Push the latch plate into the buckle until it clicks.
If the latch plate will not go fully into the buckle,
check if the correct buckle is being used.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-32.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
1-26

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 1-32.
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 vehicle’s 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.

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.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.Airbags plus lap-shoulder belts offer protection for
adults and older children, but not for young children
and infants. Neither the vehicle’s safety belt system
nor its airbag system is designed for them. Every time
infants and young children ride in vehicles, they
should have the protection provided by appropriate
child restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
{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.
1-36

{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
CAUTION: (Continued)
CAUTION: (Continued)
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.
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.
1-38

{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.
Child Restraint Systems
A rear-facing infant
seat (A) provides restraint
with the seating surface
against the back of
the infant.
The harness system holds the infant in place and,
in a crash, acts to keep the infant positioned in
the restraint.
1-39

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 1-43for 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.
