GMC YUKON XL 2007 Repair Manual

Child Restraints
Older Children
Older children who have outgrown booster seats
should wear the vehicle’s safety belts.
If you have the choice, a child should sit in a seat
that has a lap-shoulder belt and get the additional
restraint a shoulder belt can provide.
Q:What is the proper way to wear
safety belts?
A:If possible, 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.
Accident statistics show that children are safer if
they are restrained in the rear seat.
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.
61

{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 rear seat outside
position, move the child toward the center
of the vehicle. If the child is sitting in the
second row center 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. SeeRear Safety Belt Comfort Guides
on page 56. If the child is so small that the
shoulder belt is still very close to the child’s face
or neck, you might want to place the child in a
rear seat that has a lap belt, if your vehicle
has one.
62

{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.
63

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.
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.
64

{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.
65

{CAUTION:
Children who are up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer protection for
adults and older children, but not for
young children and infants.
CAUTION: (Continued)
CAUTION: (Continued)
Neither the vehicle’s safety belt system
nor its airbag system is designed for
them. Young children and infants need the
protection that a child restraint system
can provide.
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.
66

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.
67

Child Restraint Systems
An infant car bed (A), a special bed made for use
in a motor vehicle, is an infant restraint system
designed to restrain or position a child on a
continuous at surface. Make sure that the infant’s
head rests toward the center of the vehicle.A rear-facing infant seat (B) 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.
68

A forward-facing child seat (C-E) provides restraint
for the child’s body with the harness and also
sometimes with surfaces such as T-shaped
or shelf-like shields.A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.
69

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 73for more information. A child can
be endangered in a crash if the child restraint is
not properly secured in the vehicle.
