Looking for basic "training" info beyond the Owner's Manual

Recently bought a '14 TRD V6 4WD. The various handling/traction features designed into the vehicle receive cursory and overly-brief mention in the manual. I'm talking VSC, A-TRAC,
Auto LSD, Rear Diff. Lock, Downhill assist, etc. I need more understanding about the what, how, why, and when of these systems than this manual will ever provide, like systems descriptions and a user's manual, you might say. Can anyone point out a source?

Thanks Eddo. That's what I'm talking about.
