Yes, 5w-20, not 0w-20, WrongGlow. Check the 0w-20 section. See the Yaris listed there? Of course you don't.

And I never found the part about vehicles "NOT COVERED" ...I think it states "each vehicle" after stating: ILSAC GF–4 can be used in all Toyota and Scion engines.

It's dealing with all Toyota and Scions, not Hondas and Hyundais
