A3 interior dashboard question
 

Hello forum, I recently purchased a used 2007 A3 2.0 FF, and it didn't come with a user manual, so I am lost on how to change the red-text display you see thru the steering wheel. Especially the info displayed above the gear info... it used to display remaining fuel distance (240miles etc) at some point some button got pushed and now it shows how long I've been driving? (108hrs 10min)
What other info can be displayed here and how do you change it?!
