I did some research online and found that page 6 of the 05 Prius warranty info shows that the hybrid battery is covered for 10 yr/150k miles under CA emission control warranty. Other emission control related parts are covered for 15yrs/150k miles. CA emission warranty also applies to Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont. I can only assume that this will apply to the 06 Prius and the 07 Camry as well.

I found a couple articles that mention the 07 Camry having these extended warranty periods in the above mentioned states.
