FORD 2013 F-150 v.1 - Manual (Page 33)

The tether strap anchors in your vehicle are in the following positions
(shown from top view):
• F-150 Regular Cab
• F-150 SuperCrew and SuperCab
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.
If you install a child seat with rigid LATCH attachments, 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.
Once the child safety seat has been installed using either the safety belt,
the lower anchors of the LATCH system, or both, you can attach the top
tether strap.
