Hello! I recently learned how to use VDASH 2.0 to configure the car's settings, when it comes to the headlights where are the differences between the three options "DRL - Zero Position" "DRL - automatic" "DRL - day automatic"?

Currently mine is set to where the dipped beams are always on except when it's in the Parking lamp position, and I would like to change it but am confused mainly between the auto and day auto.

Sorry if I seem dumb for writing this post, I am new to all this and as a Volvo owner (2011 Volvo C30 T5 M66) and not sure where to ask question when it comes to the configuration options in vdash.
