2008 GMC SIERRA ECU

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.
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.
1-46

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.
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.

Do not install a child restraint in the center seat position.
SeeSecuring a Child Restraint in the Center Front
Seat Position on page 1-57for more information.
For regular cab models, the top tether anchors are
located under covers on the back panel behind
the passenger seat. Remove the trim plug to access the
anchor. 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.For crew and extended cab models, the top tether
anchors are the loops located near the top of the
seatback for each rear seating position. These loops will
be used to route the top tether through, as well as, to
secure the top tether in the vehicle. Be sure to use
an anchor (loop) located on the same side of the vehicle
as the seating position where the child restraint will
be placed.
Be sure to read the instructions following to properly
install a child restraint using these loops. Regular Cab

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.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat. See
Where to Put the Restraint on page 1-44for additional
information.
Securing a Child Restraint Designed for
the LATCH System
{CAUTION:
If a LATCH-type child restraint is not attached
to anchors, 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 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.
{CAUTION:
Each lower anchor and top tether anchor in the
vehicle is designed to hold only one child
restraint, except the center top tether anchor in
crew and extended cab models. 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 if this
happens. To help prevent injury to people and
damage to your vehicle, attach only one child
restraint per anchor.
1-50

{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their neck
and the safety belt continues to tighten.
Secure any unused safety belts behind the
child restraint so children cannot reach them.
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.
Be sure to follow the instructions of the child
restraint manufacturer.Notice:Contact between the child restraint LATCH
attachment parts and the vehicle’s safety belt
assembly may cause damage to these parts. Make
sure when securing unused safety belts behind
the child restraint that there is no contact between
the child restraint LATCH attachment parts and
the vehicle’s safety belt assembly.
Folding an empty rear seat with the safety belts
secured may cause damage to the safety belt or the
seat. When removing the child restraint, always
remember to return the safety belts to their normal,
stowed position before folding the rear seat.
