How do you reset the service indicator on 2000 Mercedes C230?

Turn ingnition key to position 2(do not start). Go to where it says milage. Press up twice on steering wheel till it displays the service. Press and hold the reset button on the right side of the instrumnet cluster till it displays release and hold another 3 seconds. release and your done. It is a combination of button presses using the time and odometer reset buttons. I need to do my own but don't know the sequence. There is a publication with them in, which most decent service stations/garages should have. This process is for a 2001 and newer. (w203) This is the process for the older ones The car Key must put into the second Position. (Not starting Position, but all Lights on) Then you must double push the little "0" Button. (You have only 2 Seconds to do it)

Then take the Key in Position 0.

Then Push the little "0" Button and hold him.

Then again take the Key on Position 2 with holded "0"-Button.

After ca. 10 seconds, it makes a Beep and the Service Meter is resetet.
