I'm a greatgrandma, so yes I drive like a granny (gentle acceleration away from stop), therefore the "sluggishness" of ECO mode doesn't bother me, and the restriction it imposes on accelerator pedal actually lets me "feather" the acceleration especially if I have something in the car that I don't want to bang around or topple over; or if the pavement is wet or slippery or muddy
can confirm that the ECO button on the 2015 S model is on the steering wheel
