On my 2004 Journey with the same TripTek set up the little oil can is a maintenance reminder, so don't panic. It is just a set point and not a warning device. When you start the engine you will get the check list, one of the items will show as a maintenance question. Try reset and see what happens. I don't have my manual handy.
