Ford 2015 FLEX Owner's Manual page 170

Note: In the unlikely event that the third row power seat stops
prematurely, or travels to an unexpected position, press the FOLD
button (C) to reset the seat and return it to a normal position.
WARNING: Do not drive the vehicle when the third row seat is
rotated backwards. During a sudden stop, the safety belts are not
functional in this position and the third row seat can rapidly tip back to
the forward position, all of which may result in serious injury.
Closing the Liftgate
WARNING: To avoid injury to third row occupants when closing
the liftgate, make sure that the head of any occupant is not in
the path of the closing liftgate.
