Chime / Warning Sound

[taleof2bricks]

Every now & then, my 08 sedan gives off a 4-bell chiming sound.

There are 2 chimes, followed by about a 1 second delay, and then 2 more chimes.

I perform a system check, and the "OK" message comes up. There are no warning/indicator lights on the dash or the center screen. My seatbelt is on, the parking brake off, & I can find no reason for this "warning".

I did a quick search on here but didn't find anything.

The car seems fine, but this has to mean something.

Anyone know what this is?

Thanks
