GMC ENVOY 2004 Service Manual

{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 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’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 continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.
1-35

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.
1-36

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 do 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. 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.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
nd these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system or
the LATCH 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. We,
therefore, recommend that child restraints be secured
in a rear outside seat position 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.Neverput a rear-facing child restraint
in the front passenger seat. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag.
Always secure a rear-facing child restraint in a
rear seat outside position.
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 outside position.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, do not 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.
1-39

In Canada, the law requires that forward-facing child
restraints have a top strap, and that the strap be
anchored. In the United States, some child restraints
also have a top strap. If your child restraint has a
top strap, it should be anchored.
{CAUTION:
Each top tether bracket is designed to anchor
only one child restraint. Attaching more than
one child restraint to a single bracket could
cause the anchor to come loose or even break
during a crash. A child or others could be
injured if this happens. To help prevent injury
to people and damage to your vehicle, attach
only one child restraint per bracket.
Anchor the top strap to one of the following anchor
points. Be sure to use an anchor point located on the
same side of the vehicle as the seating position
where the child restraint will be placed.
Raise the head restraint and route the top strap under
it. SeeHead Restraints on page 1-5.
Once you have the top strap anchored, you will be
ready to secure the child restraint itself. Tighten the top
strap when and as the child restraint manufacturer’s
instructions say.

Top Strap Anchor Location
Anchor brackets for the rear seat positions are located
on the oor in the cargo area of your vehicle (Envoy
only). Do not use the rear tie-down brackets near
the liftgate for top strap tethers.An anchor bracket for a top strap is located at the
bottom rear of the seat cushion for each seating position
in the second row (Envoy XL only). Don’t use a child
restraint with a top strap in the right front passenger’s
position or in the third row, because there’s no place to
anchor the top strap. Envoy

Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle has the LATCH system. You’ll nd
anchors (A) in the rear outside seat positions.
This system, designed to make installation of child
restraints easier, does not use the vehicle’s safety belts.
Instead, it uses vehicle anchors (A,B) and child
restraint attachments to secure the restraints. Some
restraints also use another vehicle anchor to secure a
top tether strap (C).
1-42

In order to use the LATCH system in your vehicle, you
need a child restraint designed for that system.
To assist you in locating the
lower anchors for this child
restraint system, each
seating position with the
LATCH system has a label
on the seatback at each
lower anchor position.
The labels are located near the base of the rear outside
seat positions.
{CAUTION:
If a LATCH-type child restraint is not attached
to its anchorage points, the restraint will not
be able to protect the child correctly. In a
crash, the child could be seriously injured or
killed. Make sure that a LATCH-type child
restraint is properly installed using the
anchorage points, 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.
1-43

Securing a Child Restraint Designed
for the LATCH System
1. Find the LATCH anchorages for the seating
position you want to use, where the bottom of the
seatback meets the back of the seat cushion.
2. Put the child restraint on the seat.
3. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will show you
how.
4. If the child restraint is forward-facing, attach and
tighten the top tether to the top tether anchorage.
The child restraint instructions will show you
how. Also seeTop Strap on page 1-39.
5. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, simply unhook the top
tether from the top tether anchorage and then
disconnect the LATCH attachments from the LATCH
anchorages.
