84 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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, below the anchorage sym-
bols on 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 gap
between the seatback and seat cushion.
