I've gotten into a five point checklist when entering the Fiesta. Seatbelt, turn car on, select USB play from audio, adjust aircon or put windows down and check lights/fuel etc. Give it a month or so and putting recirculate on will come as natural as the left hand indicators!
And for the record, you have have gone down a size but I reckon you've upgraded! The Fiesta is a little ripper, hope your driving experience with it is an enjoyable one.
