Its on the USDM models. You can adjust to lock the doors when the car moves and unlock the doors when you shift into park. You can also adjust the unlock settings to unlock all doors and the hatch with one press on the unlock button on the key as opposed to factory default which is one press unlocks driver door, two presses unlocks passenger door and hatch.I find out this on you tube:
