Actually, the green indicators are a countdown until you have to service your car. They will go out one at a time until you get to the solitary yellow and red. As for mileage until lights go out, that all depends upon driving style and driving conditions. I went through the service light reset procedure for both the Oil Service and the Inspection Service. Now, the car displays 4 Green O Yellow O Red. I really expected O Green O Yellow O Red. Will the 4 Green go out in a day or two? Did I miss something?
