2011 Chevrolet Equinox Q&A
2011 Chevrolet Equinox Question: Does leaving the Eco button on damage the engine on a 2011 Equinox?
Total BS.!!!! Check owners manual, if so it is surely in there! - pushrod
Try another dealer! Was your 'check engine' light on? Sounds to me like the 'eco' button isn't very ECOnomical. How many miles on it and did you have it serviced regularly at that dealer? - ziptie12
