Interesting, here's now I interact with my HVAC button:

1. Look at it

2. If it's slightly transparent and I want to turn it on, I click it (I don't hold for a second or 2 or 10, I just click it normally) and it turns on

3. Click it again to get the full controls

4. Slide down to close the full controls

5. Click the button again to open the full controls, and click the off button to turn it off.

Then I click and slide to the right or left to increase or decrease the temperature.

Seems pretty intuitive to me.

I'm gonna try clicking and holding next time I drive to turn it off, seems really useful.
