I know I can check under-the-hood systems by using the little dial on the turn signal stalk however I only get checks for the engine, the oil, and time/date settings. How do I get the rest? I remember several months ago I was foolling around with this, not looking for anything in particular, just trying it out, and all of the icons appeared (coolant, trans, spark plugs, etc) so how come I can't seem to get to them now? I don't remember what I did that one time to get all the checks...
