It appears that "auto" lighting is a default on the car. Because if I shut the vehicle off in "parking mode" the next day the car is in "auto" mode when I start it.. And then the DRLs are not on. And, my car is not in range mode. Never have used it. Until someone (or TESLA) gives me a better explanation of this issue, I'm going to assume TESLA does not them on all the time.
