FORD 2013 Flex v.3 - Manual (Page 35)

3. Clip the tether hook to the anchor as shown. The tether hook may be
twisted 1/2 turn to improve installation.
If the tether strap is clipped incorrectly, the child safety seat may not be
retained properly in the event of a collision.
4. Tighten the child safety seat tether strap according to the
manufacturer’s instructions.
If the safety seat is not anchored properly, the risk of a child being
injured in a collision greatly increases.
If your child restraint system is equipped with a tether strap, and the
child restraint manufacturer recommends its use, Ford also recommends
its use.
