FORD 2009 F-150 v.3 - Manual (Page 159)

To reinstall the adjustable head restraint, do the following:
1. Insert the two stems into the
guide sleeve collars.
2. Push the head restraint down
until it locks.
Properly adjust the head restraint so that the top of the head restraint is
even with the top of your head and positioned as close as possible to the
back of your head. For occupants of extremely tall stature, adjust the
head restraint to its full up position.
WARNING: To minimize the risk of neck injury in the event of a
crash, head restraints must be installed properly.
Folding up the rear seats (SuperCab only)
The rear seat has a split 60/40 cushion. Each seat cushion can be flipped
up into a vertical storage position.
1. Pull control to release seat
cushion.
2. Rotate seat cushion up until it
locks into vertical storage position.
Returning the seat to seating position
WARNING: Make sure that cargo or any objects are not trapped
underneath the seat cushion before returning the seat cushion to
its original position, and that the seat cushion locks into place. Failure
to do so may prevent the seat from operating properly in the event of
a crash, which could increase the risk of serious injury.
