Addendum (adding as a separate post), but I want to respond to this specifically: > But to forbid me, presumably an adult, is a different thing. I prefer to own my own property. I appreciate you accept responsibility for yourself, but please understand that it's a real legal argument to say "well, nothing specifically said I __couldn't__ do $thing, so I assumed it was safe to do so. I never imagined $thing could be so disastrous! Why didn't you include a warning?" Such matters always boil down to a fairly protracted argument, sometimes of the legal persuasion depending on the country of residence for the customer. It really is a case of a few bad eggs ruining the bunch. No one will stop you from hacking the car (e.g., the Mercedes police aren't gonna roll-up and arrest you for opening the hood), but for sure if they find your attempted repairs actually exacerbated an issue, the clause helps back that they tried to warn you "don't mess with this stuff it's not supported".
