What are these Bolt EV buttons for?

I was over on the other Bolt forum and this question came up that caught my attention. The original question was what are the three empty buttons to the right of the Traction Control off button for? I found a good image of the buttons in the Ampera E so they are used on the Opel but now I'm wondering what Opel uses them for?



It looks like something to do with parking and I'm guessing something to do with lane departure warning?
