It's not dumb if you read the manual..........It's an indicator, has nothing to do with pressure. On my Aprilia it says "service" on the display when the appropriate mileage comes for the oil change and I've seen guys that thought that meant there was a problem. Problem is people don't read thier owners manuals. Not giving you a hard time, but it's in there. Okay, so I am giving you a little crap
Hold down the button and turn on your key till you see the WS in the corner of the display, then push the button to cycle thru the modes till you get to the oil can, reset and you're good to go.
