 The eco-mode lowers the mpg  in city and on the freeway so I have no idea what the point of it or what it's function is actually supposed to be.   Also the radio is really annoying since I have three satellite presets I can either alter remove or replace so now I get to scan through three useless blank stations anytime I want to go from FM to my phone.   I have no idea why dealerships have been putting that on the display ever basically trying to force you to pay you for crappy service from a crappy company just makes your company look weak.   Also the dealership severely lacked in communication and getting back with me on items to be repaired post buy within the stipulations of the contract.
