FORD 2015 Expedition - Manual (Page 27)

If you install a child seat with rigid LATCH attachments, and have
attached the top tether strap to the proper top tether anchor, do not
tighten the tether strap enough to lift the child seat off the vehicle seat
cushion when the child is seated in it. Keep the tether strap just snug
without lifting the front of the child seat. Keeping the child seat just
touching the vehicle seat gives the best protection in a severe crash.
Perform the following steps to install a child safety seat with tether
anchors:
Second row seating positions
1. For center seating positions, route the child safety seat tether strap
over the back of the seat.
For outboard seating positions, route the tether strap under the head
restraint and between the head restraint posts. If the top of the safety
seat hits the head restraint, recline the seat back slightly to obtain
proper fit.
2. Locate the correct anchor for the selected seating position.
