I hate it with a passion.

Your car defaults to engine stop / start during short stops Ian. Pressing the button disables the function until you recycle ignition (or press it again).

Thankfully i don't have it on mine (hence my ignorance about the button) but my friend has it on her Audi - complete and utter pain in the rear! If it was me, i'd turn it off as well, puts undue strain on the starter and no doubt the battery too (although cars with Start-Stop have beefier batteries to cope, allegedly) not to mention taking the decision making from me. I'm a big boy now, i know when to switch the engine off due to long delays due to roadworks, heavy traffic etc.

Is the Eco button on the Climate Control (heater) panel Ian? If so, it will almost certainly switch the AC compressor off but normal operation will let the AC compressor run as and when necessary. If it's with the gear selector, i would guess it's an economy mode for the gearbox.
