Yesterday while at the dealer test driving the car, I discovered that the menu buttons which are located on the instrument cluster bezel
as you can see in this screen grab from YouTube.
This set of menu buttons actually controls many of the functions within the car, such as how the radio's power is switched, even if you want it to be switched (meaning you have to turn on/off manually) or like it was in the demo car, to automatically be powered when started or in the ACC/ON position or off when off and the key removed like in all cars these days, or you can set it to delay off if you want so you can shut the car down and have it stay on for a few minutes, stuff like that, making the car fairly customizable in that regard.
The car DOES have daytime running lights and are located in the lower light housing as seen here.
The top bulb (clear) is the daytime lamp, the lower bulb (amber), separated by a divider and when in DLR mode or perhaps when all lights are on, the DLR lamps remain lit until you turn on the turn signal, then the lamp on the side that is blinking goes out until the signal is canceled, then it comes back on, ditto for both sides when using the 4 way hazards. It is obvious in this video of the 500 as a series of unedited clips shows in several scenes as seen
here.
And finally, the intermittent wiper function is a single speed, though I just now realized if that isn't also adjustable via the menu as well or is it simply a fixed single swipe interval speed and no more.
