Actually, I'm not confused at all, just bemused by fuses in my 2004 Prius. One of the 12v outlets stopped working, and I found that its 15A fuse had blown. No big deal, I thought, I'll just head over to my local Pep Boys and buy an assortment of replacement fuses, right? Wrong. Toyota used a non-standard type of fuse that they don't carry and neither of the guys who were helping me had ever seen before.
I was able to get the fuse at the Toyota dealership, of course, but at a cost 49 cents, whereas a package of 20 standard mini blade fuses was $2-3 at Pep Boys and. Oh well, it's not as if the cost is going to break the bank...
