Because you failed to fill out your profile, I don't know what country you are in. It matters because how the maintenance is indicated varies. Here in the U.S. the maintenance minder will set codes that correspond to what should be done.
Here's a PDF of those pages from a Honda owner's manual:
What year is your Insight?
If it is new to you, once it hits 15% or so I would:
Change oil & filter
Rotate tires (this really is a brake inspection)
Change the transmission fluid (use only Honda CVT fluid)
Replace the engine and cabin filters.
Once it hits 105-110k the spark plugs are due. There are 8 of them and they are really expensive. Also, valves may be adjusted if noisey.
There is no timing belt, it's a chain. I think there is a drive belt that should be changed. (For the A/C there is no alternator, the IMA motor does the charging)
