If memory serves, you have a 2000 KLT. (Helps to include it in the question for reference.) That second button should cycle the computer display, if I remember right. (Labeled "BC" in the e-bay photos I found.) Computer display on early models was a rectangular panel on left of dash showing mileage, air temp, avg speed, etc.can someone tell me what the round button is for just to the left of the starter button and should the hazard button light be on all the time when the ignition is on.
