Lincoln 2010 MKZ - Manual (Page 121)

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.
Split-folding rear seatbacks
One or both rear seatbacks can be folded down to provide additional
cargo space.
