Excellent choice and if you have the chance to get the active suspension (I have it with a package called Techno-dynamic, which includes HUD, leather seats with air ventilation (cold) and warm position, ML audio surround system with 15 spk and an amazing sound quality as usual with ML systems, adpatative xenon double led, etc.

As InRBigness said "B) Dont forget to turn it off when you get where your going" I recall that when you forget to switch off the start button or even when thje start button is in the "mliddle" (orange light), if you have the key in your pocket, and when you go out of the car, the RX generates a sound (biiiip) for this. test it!
Biiiiip more shrill also when you leave the car with the key inside and trying to close doors by pinching the handle of the door with one finger.

 

I drove over 120 miles today. Tried the ECO Mode and it was nto for me. I am getting 28-31mpg in the regular lode just driving normal and am happy.

To me the ECO Mode could get you in trouble!
