I get frustrated because many of the TT systems are glossed over in the owner's manual. That's mainly because many of the components are built by other companies and installed in the TT, so each component has their own manual. But the problem is that there is a lot of information "missing" between what is in the TT manual vs. the component manuals. Sometimes each refers to the other, and that creates gaps.
Auto manuals tend to be much more detailed, but a lot of that info is safety oriented because of our over-litigious society.
