when the 1 is in the corner then you are on journey trip, this will reset if the car is not moved for 2 hours or more. When the little 2 is in the corner then this is overall data and will keep on counting until you mannually reset it.
Without going to sit in the car I think you get, Average mpg, current mpg, distance travelled and time travelled. I have seen some with a range of fuel on too, think this is only on an r32 tho
