Ford 2001 Windstar Owner's Manual page 165

Do not attach a child seat to any lower anchors used for child
seat installation if an adjacent child seat is attached to that
anchor. In a crash, one anchor may not be strong enough to hold two
child 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 safety
seats with LATCH lower anchors
and LATCH-compatible attachments.
Attach the lower anchors for child seat installation or lower
anchors for child seat installation-compatible child seat only to
the appropriate locations shown.
If you install a child seat with rigid LATCH attachments, do not tighten
the tether strap enough to lift the child seat off the seat when the child
is seated in it. Keep the tether strap just snug without raising the front
of the child seat. Keeping the child seat just touching the front of the
vehicle seat gives the best protection in a severe crash. Once you have
installed the lower anchors for child seat installation safety seat, assure
that the seat is properly attached to the lower anchors for child seat
installation and tether anchors. Also, test the safety seat before you
place the child in it. Tilt the seat from side to side. Also try to tug the
seat forward. Check to see if the anchors hold the seat in place.
If the safety seat in not anchored properly, the risk of a child
being injured in a collision greatly increases.
