FORD 2003 Explorer Sport Trac v.1 - Manual (Page 104)

Your vehicle has LATCH anchors for child seat installation at the
following locations:
The LATCH anchors on both sides
of the center of the rear seat are
provided only for child seats at the
outboard seats. These anchors are
further apart than the pairs of lower
anchors for child seat installation at
other seats. DO NOT install a child
seat with LATCH attachments (rigid
or mounted on belt webbing) to the
lower anchors on both sides of the center rear seat. If you install a child
seat at the center rear position, use the vehicle belt and the top tether
anchor.
Never attach two LATCH child safety seats to the same anchor.
In a crash, one anchor may not be strong enough to hold two
child safety seat attachments and may break, causing serious injury or
death.
The lower anchors for child seat
installation are located at the rear
section of the rear seat between the
cushion and seat back.
Follow the child seat manufacturer’s instructions to properly install a
child seat with LATCH attachments.
Attach LATCH lower attachments of the child seat only to the
anchors shown.
