Locating The LATCH Anchorages
The lower anchorages are round bars that are
found at the rear of the seat cushion where it
meets the seatback. They are just visible when
you lean into the rear seat to install the child
restraint. You will easily feel them if you run your finger
along the gap between the seatback and seat cushion.
