There are no HVAC controls on the steering and limited(?) infotainment controls.
Source audio, skip forward/backward, vol +/-, next application (navi, phone and music) and a "shift" button that contextually alters some of the previously mentioned buttons. That was on the left main "spoke" of the steering wheel. Below that spoke are the telephone, back and voice control buttons. The right side is for the dash, so I won't go into it.
Obviously, I have the navi as a next application because I have the Touring trim... so that won't apply for non-navi trims. Not sure if you lose any other buttons on non-navi trims.
That said, I generally leave my HVAC on auto(72) and just forget about it most of the time. On the few occasions I feel like changing anything (like full front windshield or mirrror+rear), I can take a look and get the "button" I need from the touch sensitive panel pretty quickly. If there's a need max out temp, the up/down part is "slide" sensitive, so just slide it up or down to go between hi/72/low.
I've seen various online arguments about the touchscreen HVAC being dangerous, but I feel that's for people that most likely take "too long" a time to looks at things. As quickly/aggressively as I drive, I make sure I have enough room around me, so I feel fairly safe to do things like, take a moment for such a quick glance. The same amount of time, as if looking down at the speedo or GPS.
Maybe, during the test drive, before you actually start moving, pretend you're driving and see just how quickly you can recognize things from just glancing down.
