I'm not sure what your last question is about they didn't explain the harness issue? The headrest goes up to give taller children head protection when using the seat in booster mode. I agree it is confusing and probably the #1 misuse for the seat. The harness absolutely can not be used if the child's shoulders are above the 2nd from the top slots. The seat has been tested in booster mode, if your sil is over the 2nd from top slots and over 30# I'd be using it w/ a lap shoulder belt even though it's not the preferred way for a child to be restrained it's the only approved way at this point in this seat. The harness needs to be completely removed in booster mode as well.
It should be stamped into the plastic on the back of the seat.
