2006 GMC SIERRA child seat

Your vehicle, except for regular cab models, has lower
anchors and top tether anchors. Your child restraint
may have lower attachments and a top tether.
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.
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 top tether-equipped child restraints 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.

anchors for each seating position located on the back
panel of your vehicle, behind the rear seat. Remove the
trim covers to access the anchors.Do not secure a child restraint in the front passenger’s
position if your vehicle has rear seats, if a national
or local law requires that the top tether be attached, or if
the instructions that come with the child restraint say
