Read my just entered correction. The light you indicated should only be on with marker lights tail lights etc all lights but headlights(LED DRLs would be on). Off is correct if in auto or on. The other indicator the one I did not circle above would light for headlights on. And yes there is a different light for Fogs. Fogs are only on when headlights are on. If in Auto and light sensor knows it is day then headlights and fogs would be off. If night then both would be on and the light you indicated would be off.
Strange. So you are saying when your headlights are on the same light shows up as in the photo I've posted? :O
On mine that light shows when LEDs are on and when headlight is on another green light is on and foglights have a different indicator. At least that's how it is on my car.
