Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide
added safety belt comfort for older children
who have outgrown booster seats and for some
adults. When installed on a shoulder belt, the
comfort guide positions the belt away from
the neck and head.There is one guide for each outboard passenger
position in the rear seat. Here is how to install
a comfort guide to the safety belt:
1. Pull the elastic cord out from between the
edge of the seatback and the interior body
to remove the guide from its storage clip.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts during
the early stages of a moderate to severe frontal
or near frontal crash if the threshold conditions for
pretensioner activation are met.
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. See
Replacing Restraint System Parts After a Crash on
page 83.
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. 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.
Q:What is the proper way to wear safety
belts?
A:An older child should wear a lap-shoulder belt
and get the additional restraint a shoulder belt
can provide. The shoulder belt should not cross
the face or neck. The lap belt should t snugly
below the hips, just touching the top of the
thighs. It should never be worn over the
abdomen, which could cause severe or
even fatal internal injuries in a crash.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
In a crash, children who are not buckled up can
strike other people who are buckled up, or can be
thrown out of the vehicle. Older children need
to use safety belts properly.

{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt can not properly spread the
impact forces. In a crash, the two children
can be crushed together and seriously
injured. A belt must be used by only one
person at a time.
Q:What if a child is wearing a lap-shoulder
belt, but the child is so small that the
shoulder belt is very close to the child’s
face or neck?
A:If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle.
Also seeRear Safety Belt Comfort Guides on
page 35. If the child is sitting in the center rear
seat passenger position, move the child toward
the safety belt buckle. In either case, be sure
that the shoulder belt still is on the child’s
shoulder, so that in a crash the child’s upper
body would have the restraint that belts
provide.

{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the
belt in this way, in a crash the child might
slide under the belt. The belt’s force
would then be applied right on the child’s
abdomen. That could cause serious or
fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just
touching the child’s thighs. This applies belt force
to the child’s pelvic bones in a crash.

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:
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.
