In addition to all of the above, it can also seriously depend on which drain plug you choose to use...
More than a few DYSelfers (and so-called professionals at QuickyLube places, too) have drained the CVT on these cars and then simply dumped in the 5 Qts of synthetic 0W-20 and drove away. In this case 5 Qt is the wrong amount in the wrong place.
Doing this can really ruin your day, too. :1pat:
