Is it the trip computer? If so the right hand stalk has several buttons on to cycle up and down through the options, average speed, trip time, distance, fuel consumption, average fuel consumption. Outside temperature displays as well. The computer has two memories so that one can be reset for a trip and one can just follow your average fuel etc over a longer time. There is a button to toggle between the two memories, that may be where the 1 and 2 come from... As for the problem where it blanks out it has happened to me on a few occasions and is proving to be intermittent, with the display working more often that not. Hope this helps.
