2009 HUMMER H3 belt

The manufacturer’s instructions that
come with the booster seat, state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the below t test:
Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
Buckle the lap-shoulder belt.
Does the shoulder belt rest on the
shoulder? If yes, continue. If no,
try using the rear safety belt
comfort guide. See “Rear Safety
Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-20
for more information. If the
shoulder belt still does not rest on
the shoulder, then return to the
booster seat.
Does the lap belt t low and snug
on the hips, touching the thighs?
If yes, continue. If no, return to the
booster seat.
Can proper safety belt t be
maintained for the length of the
trip? If yes, continue. If no, return
to the booster seat.
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. This applies belt
force to the child’s pelvic bones in
a crash. It should never be worn
over the abdomen, which could
cause severe or even fatal
internal injuries in a crash.Also see “Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt
on page 1-20.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position.
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.
1-26 Seats and Restraint System

{CAUTION
Never do this.
Never allow two children to wear
the same safety belt. The safety
belt can not properly spread the
impact forces. In a crash, the two
children can be crushed together
and seriously injured. A safety
belt must be used by only one
person at a time.
{CAUTION
Never do this.
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly.
In a crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury. The child
might also slide under the lap belt.
(Continued)
CAUTION (Continued)
The belt force would then be
applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.

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.

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.
{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.A forward-facing child seat (B)
provides restraint for the child’s body
with the harness.A booster seat (C) is a child
restraint designed to improve the t
of the vehicle’s safety belt system.
A booster seat can also help a child
to see out the window. (A) Rear-Facing Infant Seat

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 1-34for 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.
Where to Put the
Restraint
According to accident statistics,
children and infants are safer when
properly restrained in a child restraint
system or infant restraint system
secured in a rear seating position.
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
1-32 Seats and Restraint System

seat; an older child riding in a booster
seat; and children, who are large
enough, using safety belts.
A label on the sun visor says, “Never
put a rear-facing child restraint 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
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.
(Continued)
CAUTION (Continued)
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 1-54for additional
information.When securing a child restraint in a
rear seating position, study the
instructions that came with the
child restraint to make sure
it is compatible with this vehicle.
Wherever a child restraint is
installed, 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
the vehicle — even when no child
is in it.

Lower Anchors and
Tethers for Children
(LATCH)
The LATCH system holds a child
restraint during driving or in a crash.
This system is designed to make
installation of a child restraint easier.
The LATCH system uses anchors in
the vehicle and attachments on the
child restraint that are made for use
with the LATCH system.
Make sure that a LATCH-compatible
child restraint is properly installed
using the anchors, or use the
vehicle’s safety belts to secure the
restraint, following the instructions
that came with that restraint, and
also the instructions in this manual.
When installing a child restraint with
a top tether, you must also use either
the lower anchors or the safety belts
to properly secure the child restraint.
A child restraint must never be
installed using only the top tether
and anchor.In order to use the LATCH system in
the vehicle, you need a child restraint
that has LATCH attachments.
The child restraint manufacturer will
provide you with instructions on how
to use the child restraint and its
attachments. The following explains
how to attach a child restraint with
these attachments in the vehicle.
Not all vehicle seating positions or
child restraints have lower anchors
and attachments or top tether
anchors and attachments.
Lower Anchors
Lower anchors (A) are metal bars
built into the vehicle. There are
two lower anchors for each
LATCH seating position that will
accommodate a child restraint
with lower attachments (B).Top Tether Anchor
A top tether (A, C) anchors the
top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment (B) on the child restraint
connects to the top tether anchor in
the vehicle in order to reduce the
forward movement and rotation of
the child restraint during driving or
in a crash.
The child restraint may have a
single tether (A) or a dual
tether (C). Either will have a
single attachment (B) to secure
the top tether to the anchor.
