Maybe you could wait for about 5 seconds for the hatch to close and walk away? as long as you are within range of the rear hatch or one of your front doors when the hatch closes......it should auto lock.
I think you bought a JDM Model. I use to drive a JDM Harrier about 15 years ago. Same thing on my console, all in Japanese. But I learn what those numbers stands for after a while.
