I don't have the book with me for our '03, but I think 30k miles for engine air filter & cabin air filter. Probably 2 years for fresh brake fluid. So YES the owner's manual DOES have stuff scheduled before 100k.

There should be a bunch of inspections, like brake pads & rotors. They aren't scheduled for replacement because some people get 70k, others get 30k miles.

No timing belt because it's a chain (at least for the 4-cyl. engine).
Spark plugs at 110k miles, but I'll probably pull mine to look at them before then.

I think they say the 5-speed tranny is filled 'for life', but I personally don't believe it. Maybe I'll change that oil at 50k or something? I haven't really decided how often.
