I have learned in a different thread in here that our 09's do not have an ECO light and instead have a "Fuel Saver" light. I have been told they mean the same exact thing. The fuel saver light is also on the EVIC and the light come on at the lower right corner of the EVIC instead of the top center.
If you do not see the fuel saver light ever, I believe you may need a reflash of your ECU at the dealer to remedy that. Search around in here, and you will find threads discussing the new ECU flash.
