2007 GMC SIERRA ECU

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.
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 58for 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 your vehicle — even
when no child is in it.
54

Securing the Child Within the Child
Restraint
There are several systems for securing the child
within the child 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. The ve-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 a at 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.
{CAUTION:
A child can be seriously injured or killed
in a crash if the child is not properly
secured in the child restraint. Make sure
the child is properly secured, following
the instructions that came with that
restraint.
Because there are different systems, it is important
to refer to the instructions that come with the
restraint. A child can be endangered in a crash if
the child is not properly secured in the child
restraint.

Where to Put the Restraint
Accident statistics show that children are safer
if they are restrained in the rear rather than
the front seat.
We recommend that children 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.
A label on your 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.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
CAUTION: (Continued)
CAUTION: (Continued)
restraint would be very close to the
inating airbag. Be sure the airbag is off
before using a rear-facing child restraint
in the right front seat position.
Even though the passenger sensing
system or airbag off switch are designed
to turn off the passenger’s frontal airbag
under certain conditions, no system is
fail-safe, and no one can guarantee that
an airbag will not deploy under some
unusual circumstance, even though it is
turned off. We recommend that rear-facing
child restraints be transported in vehicles
with a rear seat that will accommodate a
rear-facing child restraint, whenever
possible.
If you need to 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.
56

If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, we
recommend that rear-facing child restraints not
be transported in your vehicle, even if the airbag
is off.
{CAUTION:
A child in a child restraint in the center
front seat can be badly injured or killed by
the right front passenger’s airbag if it
inates. Never secure a child restraint in
the center front seat. It is always better to
secure a child restraint in the rear seat.
Do not use child restraints in the center front seat
position. The restraints will not work properly.
There is limited space in the rear seating area of
an extended cab model. If you want to secure
a child restraint in a rear seating position of
an extended cab model, especially in the rear
center position, be sure to study the instructions
that came with your child restraint to see if there is
enough room to secure your seat properly.If your vehicle has the passenger sensing system
or the airbag off switch and you need to secure
a rear-facing child restraint in the right front
passenger’s seat, the passenger’s frontal airbag
must be off. SeePassenger Sensing System
on page 97,Airbag Off Switch on page 93, and
Securing a Child Restraint in the Right Front Seat
Position (With Airbag Off Switch) on page 70or
Securing a Child Restraint in the Right Front Seat
Position (With Passenger Sensing System) on
page 76for more on this, including important
safety information.
Wherever you install a child restraint, 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)
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 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).
58

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.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. In
the United States, some child restraints also have
a top tether. Be sure to read and follow the
instructions for your 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.
