Hi. New to the site as just bought a 2014 Black Edition 1.8 auto with 3k miles on the clock. Lovely car to drive but a little underpowered compared to my previous Scirocco DSG 160. However I needed a little more space while still having a sporty looking car and the Civic fits the bill. Have a 2005 Type S in the family too and its been very reliable over the years hence still kept it. My question is what does the Eco button do on my new car? I believe it affects performance not sure how. Is it worth using, I do mostly town driving and about 7k pa, oh and is there a way to lock the doors automatically when you drive off rather than using the button? Thanks
