GMC YUKON 2003 Workshop Manual

{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can’t 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. See
Rear Safety Belt Comfort Guides for Children and
Small Adults on page 1-41. 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. 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 a seat that has a lap belt, if your vehicle
has one.

{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.
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 doesn’t 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.

{CAUTION:
Children who are up against, or very close to,
any air bag when it inflates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer outstanding protection for adults
and older children, but not for young children
and infants. Neither the vehicle’s safety belt
system nor its air bag 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.
1-48
2003 - Yukon/Yukon XL

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.
{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 lowon 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’s
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.

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 continuousflat
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.

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 thefit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have afive-point harness.
A booster seat can also help a child to see out the
window.

Q:Howdo child restraints work?
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.
For many years, add-on child restraints have used
the adult belt system in the vehicle. To help
reduce the chance of injury, the child also has to be
secured within the restraint. The vehicle’s belt
system secures the add-on child restraint in the
vehicle, and the add-on child restraint’s harness
system holds the child in place within the 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. Thefive-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 aflat 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.When choosing a 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
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system in
your vehicle, but the child also has to be secured
within the restraint to help reduce the chance of personal
injury. 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.

Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in a rear seat including an infant
riding in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding in a
booster seat. Never put a child in a rear-facing child
restraint in the right front passenger seat unless
your vehicle has the passenger sensing system and the
passenger air bag status indicator shows off. Never
put a rear facing child restraint in the right front
passenger seat unless the air bag is off. Here’s why:{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating air bag. Be sure the air
bag is off before using a rear-facing child
restraint in the right front seat position.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one can
guarantee that an air bag will not deploy under
some unusual circumstance, even though it is
turned off. General Motors therefore
recommends that rear-facing child restraints be
secured in the rear seat whenever possible,
even if the air bag 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.
1-53
2003 - Yukon/Yukon XL

If your vehicle has the passenger sensing system and
you need to secure a rear-facing child restraint in the right
front passenger’s seat, the passengers frontal air bag
must be off. SeePassenger Sensing System on
page 1-81andSecuring a Child Restraint in the Right
Front Seat Position on page 1-66for more on this
including important safety information.
Wherever you install it, be sure to secure the child
restraint properly.
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.
Top Strap
Some child restraints have a top strap, or“top tether.”It
can help restrain the child restraint during a collision. For
it to work, a top strap must be properly anchored to the
vehicle. Some top strap-equipped child restraints are
designed for use with or without the top strap being
anchored. Others require the top strap always to be
anchored. Be sure to read and follow the instructions for
your child restraint. If yours requires that the top strap be
anchored, don’t use the restraint unless it is anchored
properly.If the child restraint does not have a top strap, one can
be obtained, in kit form, for many child restraints. Ask the
child restraint manufacturer whether or not a kit is
available.
