Three immediate steps, in order:

-There should be an "Econ" button down below the radio that lights up a green leaf when you press it. That changes the TCM- it locks up the torque converter sooner and shifts less, even skipping gears. Automatics are funny- if the driver is going to be an idiot, more gears give better mpg. If the driver is willing to take some personal responsibility for it and meet the car halfway, there's a button that will give you fewer gears... for better mpg.

-Pump up the tires. I went up from 35 to 39 psi without throwing the TPMS light. It's my wife's DD and she's not a hypermiler.

-Get an SG or UG. Having multiple mpg displays helps you know what you're actually doing- the longer view, short trip and current values all work together.

My 2011 does pretty well. I reset the mileage back in June and it shows 20.3 mpg since then- which includes a few camping trips with the kids, the dog, a pop-up camper and a canoe.
