I'm curious as to what other Toyotas you have... and I'm wondering if the Japan-made ones don't have 'em but the USA-made ones do... like my Yaris and iQ are both Japan made and they don't have it while my sister's Corolla(manufactured in MS) and my dad's Sienna(manufactured in IN) have themHmmmm.....maybe we don't have a yellow warning indicator (which is a gas pump) like in my other Toyotas.
I just did turned the key on to light up all the lights (when it runs through it's start-up checks) and didn't see one.
I thought I had solved the mystery BUT then sat in my wife's Corolla and did the same (and I KNOW where her yellow warning light is) but it's not one of the ones that comes on when it runs through the start-up check.
So my question to Toyota (Scion) is if something isn't broke, why did you have to go change it? (My other Toyota's not only flash the light but they have audible beeps when they come on.)
