Yeah, that's a nice-to-use "shortcut", but it only works when you're able to see those 2 damn buttons...stabbing at the heater slider with the two finger salute
When you're driving through darker areas, they are impossible to see. On top of that, if you have a faulty interior lighting module (as I do), you're unable to switch the light on to see the temp. buttons. And then you're stuck with adjusting the heated seats from the infotainment screen - multiple "clicks"
Octavia mk4 was (still is) so much smarter/practical than the Formentor on this subject...
