I don't know why, but there are many companies that tries to spend less paper on their manuals. So there is not that much information there. I guess there are new rules for the standard politics for the world market. Always, I think that you can search for it on their website, download everything and print. Otherwise, there is
manymanuals.com, a website which is specialized in manuals. So, find the Toyota on the main page, then press Corolla and chose the years I guess. I am sure they have a more detailed manual there.
