Disclaimer: I am not 100% sure as it didn’t work out every time for me!
Push the button on the end of left steering column lever (on LHD it’s the one for high beam)
Than you should see a selection menu on the info screen (from beginning/from start or similar)
Here I do not know exactly how it is possible to select one . Maybe you can with the „wheel selector“ in the middle console.
If I am right, a longer push on the button of the steering column lever should reset your trip data.
Sorry for the uncertainty in the description. I struggle with the task and with the language as I am not 100% safe in both.
