Tested my '12 with NTG 4, same result with green towel, I think BMW is right though, NAV screen not at the same sensitivity as headlights, I believe.LOL.
So I did one test yesterday and that was driving with the car in auto in the morning the lights were on. They did not shut off when I switched it to 0. I am assuming that the control logic is once the lights are turned on with the auto you can not turn them off while underway until the auto agrees. What remains to be tried is being in 0 from the start in the dark.

My lights come on with the switch in “0” position if it is dark enough just like in AUTO position when I start the car.
Ok so I figured I would determine the functionality of the 0 position by going to my owners manual. lo and behold it shows a switch without the 0 position and no mention of the 0 position. I want my money back. I paid extra for the switch with the 0 position package and it doesn't do anything.

The command lighting change I think is time based... as it never aligns with the auto ON headlight function.

I've assumed the Comand day and night mode lighting is based on the sunrise and sunset times at the time of year and the latitude and longitude where the car is on any given day, all as determined by the car's GPS. That's how my handheld GPS's switch between day and night mode.

Time in the almanac would not count for dark cloudy days. In my car it definitely goes with the lighting conditions insider the car.

Go to your cluster menu and turn the DRLs off. Then see if “0” position kills all lights.

Re the Comand display going into daytime or nighttime lighting mode, the 2013 E Class Comand Manual (p. 38) indicates you are correct. It says you can put the display in permanent daytime mode or permanent nighttime mode or Automatic mode. As to Automatic mode, it says:
"If the Automatic setting is selected, COMAND evaluates the readings from the automatic vehicle light sensor and automatically switches between the display designs."
The canoe on my roof apparently doesn't affect the automatic vehicle light sensor as it does the headlight sensor.

Hold your horses! I think they won’t reimburse you any moneys 😊😊😊
I just tested it in my S-class. When I turn the DRLs OFF in the cluster menu the “0” position in the lights switch turns OFF all lights. And I remember it works exactly this same way in me E-class.
What is Mercedes thinking with logic like this does not make sense to me but this is how them lights behave in my two cars with the “0” position in the lights switch.

Thanks for your post. I have noticed in many cases how Comand changes to night mode in daytime if I'm stuck under on over pass for long enough. Has nothing to do with a clock. Then it changes back to day mode when back in full daylight.
I forgot there was a separate Comand manual to read about it all...

This part I don't understand...
I pulled into the garage today, the headlights came on [auto] and a few seconds later the command screen switched to night mode. That would align with what pierrejoliat posted. Is there really another light sensor besides the one that triggers the headlights?

From what I can see, there are four light sensors around the camera, I suppose one could take the experiment to the next level covering each individual sensor until the lights came on and then cover one more at a time to see when the NAV screen changes? I believe it's been confirmed that the light sensor on the dash is for interior/HVAC and the sensor on the rear view mirror has no effect other than the driver's side mirror and the center rear view.

There must be. It could be built in the Comand screen somehow perhaps? I always thought it is the small dome on the dash but obviously it is not. But somewhere it is.
Finally got the barge off the garage ceiling last weekend. First things first: sand and oil the woodwork. This 40+ year old boat needs tlc every now and then. I put it on the roof to dry since it has to be there anyway since we're camping in the lark this weekend. Whatdayaknow the headlights come on even in broad daylight! From this thread I now know (and have demonstrated to myself) that the car stays dark when running with the light switch in either park position.
Thanks mbworld!
