Quick update on the wiper/automatic headlight function: (this works on the Essence, not sure about the Preferred)
With lights in auto position, wipers must be turned on to full wiper motion, not intermittent, to get headlights to turn on automatically.
However:
Once you turn wipers on fully, then to intermittent the headlights will stay on and visa versa until you turn wipers off.
If you go to intermittent first without turning the wipers fully on, the headlights will not automatically turn on until you switch to full wiper mode.
There you have it! With all of the off and on thunderstorm rain jockeying over the holiday weekend and daylight travel from picnic to picnic, I had several opportunities to play around with it.
