I suspect this cool feature is on cars with a "lighting package" which I think may be standard on USA cars. (It's amazing how much more content USA cars have in the price.) And, this feature may apply to both the front and rear seats, but I've only confirmed it in the rear.

Open the a rear door and the LEDs in the rear light up in different intensities, depending on which door was opened. If you open the rear passenger's-side door, the LED puddles light on the passenger's-side rear seat and the driver's side rear seat, while illuminated, is less brightly lighted.

Open the other door and the lighting is reversed.

I've owned my car for over six months -- and I am STILL finding new things to love. These cars are amazing.
