I know what the “CALL” Button is, but I am not sure what it is you are referring to as “OK” Button, at least my 07’E63 doesn’t appear to have it as spelled out on Button(s) 1-4? I’m still trying to figure out how to clear the ( Service “H” Maintenance is exceeded by…) warning which shows itself daily?
