Hi, and welcome,
generally they are checked at the first major service..when under warranty,
that should be the bedding in..,
as long as it's run on clean oil it shouldn't really need touching again..100K miles is a good marker
the cam belt is VERY simple on the FIRE engines,
5 years is about right - always a good idea to change the idler pulley, and the waterpump at the same time.. as they are driven by the belt,
