We have a new 2021 Allegro RED 33AA. At seemingly random times while driving there is a ding sound much like what you’d hear on an airplane when the fasten seatbelt lights turn off or on. I don’t see any indicators on the dash or anywhere else that tell me what it’s for, and since it doesn’t have autopilot I’m pretty sure I’m not free to walk about the cabin. Anyone know what the ding means?
