I had the same question as well. I am a new owner, and I asked my retailer about this. This is what they have told me.
- The CVT doesn't have a "clutch" per-say, its based on a "belt" system(????). So there isn't any "parts" to wear out if you are driving in the CVT "shift-tronic" mode.
- The manual mode is a "simulation" of manual transmission, and works based on electric currents. It breaks the AT's full RPM spectrum into different parts.
So basically, from what I understand, you are still in AT mode, it just simulates MT.
Any correction from more experienced mechanics or owners are welcome.
