GMC 2011 Terrain Owner's Manual page 105

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. Be sure to read and
follow the instructions for your child
restraint.
Lower Anchor and Top Tether
Anchor Locations
Rear Seat
(Top Tether Anchor): Seating
positions with top tether anchors.
(Lower Anchor): Seating
positions with two lower anchors.
The rear outboard seating positions
have exposed metal anchors
located in the crease between the
seatback and the seat cushion.
Seats and Restraints
Top Tether Anchors
The top tether anchors for each rear
seating position are located on the
back of the rear seatback. The rear
compartment storage panel/cover
might need to be adjusted to access
the anchors. 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.
