auto repair manuals free

My father has given this Toyota 4-runner as a birthday gift. I am so much excited to drive it but still need an auto repair manuals free as I am kind of newbie. I want to know all the knowledge about this car's part and mechanism so that if I might get myself in trouble, I will be able to get it fixed by myself.  I know many of you might say that it is not necessary . It can be done by taking it to a mechanic shop. That will also reduce the hassle. But for me it is necessary that I learn these so that I need not to depend on anyone else. Who knows if I will get the necessary help I need at the critical moment? No one knows that. So it is better to get well informed about those.
