Discovered this morning with foot off the brake:
Pushing ignition puts car in accessory mode (yes, we all know this).
But pushing and holding the ignition puts the car in ON status (historically, the second click on a keyed ignition). This illuminates the 2nd light on the ignition button.
In the ON position, you are able to shift the car out of park and into neutral!!
What would be REALLY neat, is if this ignition position was also the emergency fuel filler door release. But I think this is wishful thinking!
