The repair manual is in the metric system but it is easy to convert. The same book from the USA is $55.00 and above. My Yaris is getting old enough now that it will need some minor owner performed repairs, i.e. Brake shoes and rotors with shoes and pads, radiator flush, torque values for body bolts and electrical issues are covered by a good electrical diagram.(could of been a little bigger or a fold out, none the less very good) The book does a nice job of clarifying the procedures. After 11 years, the car has still not been in the repair shop for anything..I expect this book will extend that to 15 or 20 years.
