wrote a little email to toyota a while back to ask about the UV protection rates of the yaris windshield/windows. was curious since some numbers came out for the UV protection rates of my sienna's high-solar energy absorbing windows, and they were ridiculously good (front windshield had 99.9%, while front windows had 99%). so here's what they had to say about the yaris:

"Thank you for contacting Toyota Motor Sales, U.S.A., Inc.
We apologize for any difficulty locating information about the UV protection glass of the Yaris Liftback. We apologize that the percentages you request are not available.

Toyota vehicles are manufactured to comply with U.S. Federal Motor Vehicle Safety Standards (FMVSS) for windows in effect at the time of manufacture. FMVSS requirements preempt all state requirements regarding windows (including amount of tint). The requirements for tinted windows are the same for all windows on passenger cars.

UV

UV-A is the component of sunlight that causes a tan.

UV-B is the component of sunlight that causes a sunburn.

UV-C is absorbed by the ozone layer and does not reach the earth's surface.

Ulta-Violet (UV) Blocking
The glass of our vehicles greatly reduces UV-A and almost completely blocks UV-B. UV blocking both helps protect occupants and helps delay aging of the interior upholstery.

Caveat
UV blocking rates can vary slightly from one window position to another. Also, blocking rates are not constant over the wavelength spectrum of UV.

We appreciate hearing from our customers and having the opportunity to respond accordingly."
