HUMMER H3 2010 Owners Manual

Seats and Restraints 3-47
{WARNING
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.
{WARNING
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 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.

3-48 Seats and Restraints
(B) Forward-Facing Child Seat
A forward-facing child seat (B)
provides restraint for the child's
body with the harness.(C) Booster Seats
A booster seat (C) is a child
restraint designed to improve the fit
of the vehicle's safety belt system.
A booster seat can also help a child
to see out the window.
Securing an Add-On Child
Restraint in the Vehicle
{WARNING
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.

Seats and Restraints 3-49
SeeLower Anchors and Tethers for
Children (LATCH System)on
page 3‑51for more information.
Children 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
{WARNING
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 seat; an older child riding in a
booster seat; and children, who are
large enough, using safety belts.

3-50 Seats and Restraints
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.
{WARNING
A child in a rear-facing child
restraint can be seriously
injured or killed if the right front
passenger airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
passenger airbag inflates and the
passenger seat is in a forward
position.
(Continued)
WARNING (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 3‑35for 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.

Seats and Restraints 3-51
Lower Anchors and
Tethers for Children
(LATCH System)
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).

3-52 Seats and Restraints
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.
Some child restraints that have
a top tether are designed for use
with or without the top tether being
attached. Others require the top
tether always to be attached.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. Be sure to read and
follow the instructions for the child
restraint.
If the child restraint does not have a
top tether, one can be obtained, in
kit form, for many child restraints.
Ask the child restraint manufacturer
whether or not a kit is available.
Lower Anchor and Top Tether
Anchor LocationsRear Seat
i(Top Tether Anchor): Seating
positions with top tether anchors.
j(Lower Anchor): Seating
positions with two lower anchors.
Each outboard seating position in
the rear seat has exposed metal
lower anchors in the crease
between the seatback and the
seat cushion.

Seats and Restraints 3-53
For H3T models, the top tether
anchor symbol is located near the
top tether anchors to assist you in
locating the top tether anchors.
H3T
For H3T models, the top tether
anchors are located on the back
panel behind each rear seating
position. Be sure to use an anchor located on the same side of the
vehicle as the seating position
where the child restraint will be
placed.
H3
For H3 models, the top tether
anchors are located on the back of
the rear seatbacks. Be sure to use
an anchor located on the same
side of the vehicle as the seating
position where the child restraint will
be placed. Do not secure a child restraint in a
position without a top tether anchor
if a national or local law requires
that the top tether be attached, or if
the instructions that come with the
child restraint say that the top tether
must be attached.
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. See
Where to Put the
Restraint
on page 3‑49for
additional information.

3-54 Seats and Restraints
Securing a Child Restraint
Designed for the LATCH System
{WARNING
If a LATCH-type child restraint is
not attached to anchors, the child
restraint will not be able to protect
the child correctly. In a crash, the
child could be seriously injured
or killed. Install a LATCH-type
child restraint properly using the
anchors, or use the vehicle's
safety belts to secure the
restraint, following the instructions
that came with the child restraint
and the instructions in this
manual.
{WARNING
Do not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment
to come loose or even break
during a crash. A child or others
could be injured. To reduce the
risk of serious or fatal injuries
during a crash, attach only
one child restraint per anchor.
{WARNING
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Buckle any unused safety
belts behind the child restraint
so children cannot reach them.(Continued)
WARNING (Continued)
Pull the shoulder belt all the way
out of the retractor to set the lock,
if your vehicle has one, after the
child restraint has been installed.
Notice: Do not let the LATCH
attachments rub against the
vehicle’ s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
