Cadillac 2008 SRX Owner's Manual page 49

Each outboard seating position in the second row has
exposed metal lower anchors in the crease between the
seatback and the seat cushion.
To assist you in locating
the top tether anchors, the
top tether anchor symbol
is located near the top
tether anchors.
There are two top tether anchors located on the side of
the wheel well in the rear cargo area. There is another
top tether anchor in the center of the rear cargo area.
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.
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.
