i3 Subtleties (not mentioned in the owner's manual)

[websterize]

It's early evening and you walk toward the i3, which is parked on a side street, to get something out of the trunk. You click the unlock button on the fob, and the L-shaped tail lights illuminate, along with the other welcome lights. You reach the tailgate, and, after depressing the button in the recess, the L-shaped lights go dark, and the rear fog lights in the bumper illuminate. The tailgate pivots up, and you grab the item. After you close the boot, the fog lights turn off, and the L-shaped lights illuminate again.

A thoughtful, subtle safety feature.

...The tailgate pivots up, and you grab the item..

What? By itself, the tail gate goes up after pressing the button? How did you do that?
