2003 GMC SIERRA ECU

If your vehicle has the passenger sensing system
and/or the AIR BAG OFF switch and you need to secure
a rear-facing child restraint in the right front passenger’s
seat, the passenger’s frontal air bag must be off.
SeePassenger Sensing System on page 1-66,Securing
a Child Restraint in the Right Front Seat Position on
page 1-49, andAir Bag Off Switch on page 1-61
for more on this including important safety information.
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, don’t 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.
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.

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.
If you have an adjustable head restraint, route the top
strap under it.
Once you have the top strap anchored, you’ll 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

When using a child restraint with a top strap in the
center rear position, route the top strap through
the fabric loop on the seatback. Then, raise the head
restraint and attach the top strap to the anchor
point located at the closest outboard position.
Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle may have the LATCH system. If it does,
you’llfind anchors (A) in the front passenger seat, where
the seatback meets the seat cushion, and anchors (A) in
the center rear seat, where the seatback meets the seat
cushion. For front passenger seat position, there is a top
tether anchor (C) behind and to the bottom of the seat to
secure the top strap. For center rear seat positions, there
is a top tether anchor (C) near the driver’s side rear seat
head restraint to secure the top strap.
To assist you in locating the lower anchors for this child
restraint system, each seating position with the LATCH
system will have a visible metal anchorage point in the
seat, where the seatback meets the seat cushion.

With this system, use the LATCH system instead of the
vehicle’s safety belts to secure a child restraint.
{CAUTION:
If a LATCH-type child restraint isn’t attached to
its anchorage points, the restraint won’t 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. See “Securing a Child Restraint
Designed for the LATCH System”, “Securing a
Child Restraint in the Right Front Seat
Position” or “Securing a Child Restraint in a
Center Rear Seat Position” in the Index for
information on how to secure a child restraint
in your vehicle.

to use, where the bottom of the seatback meets the
back of the seat cushion.

anchor points.
Securing a Child Restraint in a Rear
Outside Seat Position
There is limited space in the rear seating area. If you
want to secure a child restraint in a rear outside seating
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 child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-42. SeeTop Strap
on page 1-39if the child restraint has one.
If your child restraint does not have the LATCH
