I am sure that Toyota has tested the engines enough to ensure they won't grenade during the warranty period on 0W-16. Get through the warranty period on it, then switch to 0W-20 if you want. Our 2ARs runs perfect on 0W-40, though is different from the A25A.
Though, I know quite a few people that run the piss out of their cars while they are running on 0W-20 and they are fine after 200K+ miles.
