Guys, does anybody know how to reset service light after oil change on 1998 W140 S500?

"Switch ignition ON and immediately press button A twice.

Switch ignition OFF.
Press and hold button A while switching ignition ON.
After 10 seconds the new interval will appear in the display accompanied by a beep.
Release button A.
Switch ignition off."

This is what Autodata says. Button A being the "0" button below the "+ -" button to the side of the instrument housing. Sorry, but my car does not have this being an earlier model.
