FORD 2014 E-450 v.2 - Manual (Page 33)

Attach the tether strap only to the appropriate tether anchor as shown.
The tether strap may not work properly if attached somewhere other
than the correct tether anchor.
Note: 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:
Front passenger seating position
You can attach the tether directly to
the rear of the front seat.
1. Adjust the front passenger seat fully forward.
2. Route the child safety seat tether
strap over the back of the front
right-hand passenger seat as shown.
