Glad to share it. As you saw in the Tesla forum post you quoted, this is something that isn't in the owner's manual but most definitely is true.
For whatever reason (much like release notes) the Tesla owners manual is really incomplete and (philosophically speaking) reads a lot more like the owner's manual of a piece of consumer electronics (how many of us remember the "owner's manual" that used to come with an iphone before they got rid of it) as compared to the fairly thick owner's manuals that come with most cars these days? While many of the stuff that comes in ICE owner's manuals doesn't apply to Teslas (how many quarts of oil and what kind of oil necessary for oil change with and without filter change), things like detailed fusebox info/diagrams, transmission fluid specifications, specs for all the bulbs on the car, etc. make the manuals a useful reference. Heck, my wife's last Kia came with a 200 page manual for the touchscreen alone!
This is one of the ways Tesla takes a "computer industry" approach towards cars, but it does mean owners are far more reliant on forums and the internet to learn things as opposed to just "reading the funny manual" (current and former military personnel will get the reference).
