Headlight DRL Fuses or Relay Location

Good day.

I have a 2011 SL550 had a E350

I looked through countless fuse diagrams. Three in total from three different sources I found on this forum.
Not a one has the fuse or relay location for the headlights or DTR. Or, I'm not looking in the correct location.

My headlights are staying on regardless of the headlight switch position. It turns off when the ignition is turned off.

I read it could be a software update or the switch itself and that's fine but I still would like to know the location of the above mentioned.

Anyone have simple answer to a simple question.

Thank you,

Hutch

I believe that on US spec cars, it can be turned off in the settings menu. Canada and other specs might not have that option..

That was it. I was messing with the settings a week ago or so and must of inadvertently turned them on manually.
Did a factory reset and it fixed my issue.

Thank you, again.
