On a 2016 Infiniti Q50S, when you go to Settings> Meter> there is no Maintenance button. It displays Main Menu Selection and jumps to Alarms. Otherwise I have done what you specified in App Garage. Now my problem isn’t clearing Service Due, but to adjust it. It is set properly in App Garage but for some bizzare reason it is set to 16000km on my main screen and I can’t seem to adjust this. Any advice?
