FORD 2000 Windstar - Manual (Page 160)

If the safety seat in not anchored properly, the risk of a child
being injured in a collision greatly increases.
To properly install any child seat in the second or third row seats, first
set the seatback angle.
1. Pull up on the seatback recline control located on the side of the seat,
allowing the seatback to spring to its forward position.
2. Without touching the recline control, push the seatback rearward
until the recline control drops into position. (If the recline control is
pulled up during this step, the seatback will not be properly positioned.)
