I don't think the default behavior can be changed. Been like this for me since the auto seat heaters were introduced.
If I touch the passenger seat heater, the whole thing resets, and seems to show the last setting I used in the car.
Also, if I don't touch it, when I get in the car, it will be set to my last settings. I don't think it's really showing the current state, but a placeholder until it ca connect and show what your settings were last time you drove.
But it's like the light in the fridge, hard to check when it's closed. Is it really on?
