Not sure about the LED ring since I don't have the safety or luxury package. You can fool the system to see the daytime running lights by coming to a stop and leave the parking brake off while the engine is running. My wife stayed in the car with her hand hovering over the parking brake while I checked mine.
The rings illuminate with the headlights in the low beam position or the parking light position. The DRLs are on the inner portion of the headlights closest to the grill. (For cars with the led headlight option)
Would be nice if you could wire the rings as DRLs
If you want the ring light up without the headlamps in the premium collection lusso lamps, choos the second to last light setting with the twin lamp logo. Auto only shows when driving in the right conditions and full on lights all.
