When does something have to be done?

Hello, there is always something about the moose (my is n V40 2.0 T) to be replaced or renewed….and so slowly I completely lose the overview and am not sure when something has to be done. And I would be very grateful about this small list that I can add to the repair calculations in my folder so that I don’t forget anything and am on the running. Oil change: 1 x a year or every 15,000 KM spark plugs: 40,000 KM air filter/inner room filter: 1 x a year Timing belt: every 7 years or 80.000 KM brake fluid: ? Cooler frost protection: ? Air conditioning maintenance: every 2 years Would be great if one or another could still tell me what I forgot or could correct if I was wrong.
