Can I use the UAS (LATCH) anchors that are not designated for the vehicle seating position I have selected for my Fllo convertible car seat?

No. UAS (LATCH) anchors have a required standard spacing of 11 in. (280 mm) from centre point to centre point. Attaching Fllo's included UAS belt to lower anchors that are closer together or farther apart than 11 in. is NOT permitted.
