How often should I have a tune up and fluid changes

Hello: I have only had older vehicles in the past, ones I could work on myself. This 2012 model, I will have to take to a mechanic to get some things done.

My questions are:

How often does this vehicle need a tune up?

How when does it need the transmission fluid/filter changed?

Does it need the radiator flushed and filled so often, or is it one of those that is closed?


I looked in the book that came with the vehicle, but it did not state any specifics on when these need to be done, unless I overlooked it. I also looked online, but there were different answers, and I would like to know what is specific to this model.

Thanks!
