I don't have my Cross yet (my build date is May 5th), but that manual option on the CVT is news to me and I haven't seen it mentioned in reviews either. I looked it up in the Cross .PDF manual (p. 169) and it's explained there.
FYI. You can download the English version of the manual from Toyota here: 2022 Toyota Corolla Cross Manuals & Warranties | Toyota Owners
