2017 Toyota Prius Warranty
(2004 Owner's Manual is 28 files, 2004 Navigation Owner's Manual is 4 files, IIRC.) Hopefully you have the patience to find and download them all. Thank you very much. I have registered with toyoaownersonline.com and tried to view the Owner's Manual as you suggested using Firefox as well as Internet Explorer with both set to allow cookies. However, when I choose 'Owner's Manuals' I get a screen with Search Form shown but no means of entering information to be sought. What am I doing wrong? Thanks again.
Toyota Prius Service Manual
I was using Chilton and Clymer books on my first car, up until I was about 24 and bought a new car and thought I'd give the factory manuals a try, and I've never looked back. To me the completeness of information and low rate of errors makes the choice easy. Toyota puts theirs at techinfo.toyota.com (along with a whole bunch of other stuff, recalls and service bulletins with instructions, quick technical guides, and even the materials from their tech training courses if you feel like diving deep). On the US-facing site (techinfo.toyota.com) the shortest access you can request is two days for $15 (reportedly if you play it right around a weekend, you can get a bit more than two days). Sites for other regions (like toyota-tech.eu for Europe) may have other arrangements (I think you can get shorter-than-a-day increments there). As it works out, you're not getting access to 'a Toyota service manual', but to all the information the site makes available, for the duration of your access. If you have friends with other Toyota/Lexus/Scion models, for two days you can seem really smart and answer all their questions too.
