Pardon my "on-topic" post. <G>
The Toyota dealer sent me a flyer in the mail with a number of service discount coupons in it.
One that caught my eye was:
"Timing Belt Replacement Special" - Timing belt fatigue cannot be detected. The stated Factory Recommended Maintenance Schedule
My 2007 Toyota Yaris came with a "Genuine Toyota Service - 2007 Scheduled Maintenance Guide - Passport to Performance". Under 2007 Cars at 90,000 miles it states "Replace timing belt (Camry Solara with 3MZ-FE)"
So which is it? Should the Yaris timing belt be changed every 90,000 miles or not?
I think you answered your own question, there....
Check the owner's manual for your car. I believe that the Yaris has a timing chain instead of a timing belt and so does not require routine replacement.

According to the auto channel, the engine has a timing chain in the 1NZ-FE engine: http://www.theautochannel.com/news/2005/12/30/198830.html
So the Factory Recommended Maintenance Schedule is correct: On the Camry Solara with the 3MZ-FE engine, you need to change the belt at 90,000 mi. You don't have a Solara with the 3MZ-FE engine, so you don't need to change the timing belt, because you don't have one.
However, you should change the timing chain at some point. I usually wait until about 9,000,000 mi. I have only 8,855,000 mi to go!
