What is the purpose of the Eco Driving indicator on the 2012 Yaris? What does it do? - Toyota Yaris Forums

in the old days (real old days) we used to put vacuum gauges on our vehicles. They usually had a green section indicating high vacuum conditions and had it labeled as economy. See when you mash the throttle, the vacuum drops, and you get poor metering and mileage. When you run the motor with the throttle barely cracked, the motor has a very small straw to suck through, causing high vacuum conditions, and giving good mileage. I have noticed on my '12 automatic, that the light comes on when I'm not wasting gas (mashing on the pedal, but using reasonable throttle)... DOH
