Q: What are the different types ofadd-on child restraints?
A: Add-on child restraints, which
are purchased by the vehicle
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.
{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.
(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 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. See
Lower
Anchors and Tethers for Children
(LATCH System) on page 3‑57 for
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. In some areas of the United States
and Canada, Certified Child
Passenger Safety Technicians
(CPSTs) are available to inspect
and demonstrate how to correctly
use and install child restraints.
In the U.S., refer to the National
Highway Traffic Safety
Administration (NHTSA) website
to locate the nearest child safety
seat inspection station. For CPST
availability in Canada, check with
Transport Canada or the Provincial
Ministry of Transportation office.
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.

3-56 Seats and Restraints
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.
If a child restraint is secured in the
right front passenger seat, and the
vehicle has a switch in the glove
box to manually turn off the right
front passenger airbag, seeAirbag
On-Off Switch on page 3‑37 and
Securing Child Restraints (Rear
Seat Position) on page 3‑66 or
Securing Child Restraints (Right
Front Seat Position) on page 3‑69
or Securing Child Restraints (Center Front Seat Position) on page 3‑78
for more information, including
important safety information.
A label on the sun visor says,
“Never put a rear-facing child seat 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 or airbag switch
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.

Seats and Restraints 3-57
{WARNING
A child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. Never
secure a child restraint in the
center front seat. It is always
better to secure a child restraint
in a rear seat.
Do not use child restraints in the
center front seat position.
When securing a child restraint in
a rear seating position, study the
instructions that came with your
child restraint to make sure it is
compatible with this vehicle.
Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others. Always make
sure the child restraint is properly
secured. Depending on where you place
the child restraint and the size of
the child restraint, you may not
be able to access adjacent safety
belt assemblies or LATCH anchors
for additional passengers or
child restraints. Adjacent seating
positions should not be used if the
child restraint prevents access to
or interferes with the routing of the
safety belt.
If the vehicle does not have
a rear seat that will accommodate
a rear-facing child restraint, a
rear-facing child restraint should
not be installed in the vehicle,
even if the airbag is off.
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 your vehicle
—even when no
child is in it.
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.

3-58 Seats and Restraints
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 your 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 your 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.

Black plate (59,1)GMC Sierra Owner Manual - 2011
Seats and Restraints 3-59
Your 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 your
child restraint.Lower Anchor and Top Tether
