Its all listed in the manual - you have to combine the 20000 mile info and 2 year info to see what's gonna be done.

Its listed separately as some things are time dependant not mileage dependent. Useful for people like me who do 20000+ a year :(
 
The 20K and 2 years services are the same, basically oil, oil filter, pollen filter and various checks.

Separately though you should have a brake fluid service every 2 years
