I live in the US and when I did the series of instructions on my 2017 years ago, it worked perfectly and displayed only my thin DRLs (pictured) and my rear parking lights when I had the parking lights on. If I had the knob turned to OFF, everything was off. The video game cheat code makes the lights knob in the car function correctly to whatever you turn it to, instead of the headlights always being on no matter what. In five years of having that car (a drunk driver ran into me and totaled it a couple weeks ago), I was the only one I ever saw driving around with only the thin lights illuminated, or with all lights turned off.
