Press the upper button and they will illuminate. With them showing they should appear every time you restart the engine. If they don't you will have to have the ECM flashed. It goes to the last way it was set. Mine used to only come on when I manually called for them to show until I saw my brothers come on all the time. I took it to several dealers and they said that is the way it's supposed to be. BS I said. I finally told them to flash the EC M anyway and lets see what happens. Guess what it works like I said it would.
