My LE chimes on occasion and I dont know why. Tonight it was sitting still in a left turn lane. 3 chimes. The other day I was turning and it did it. I cant find anything in the manual.

Not sure about the Sienna but, some vehicles will chime if the turn signal has been on for an extended period of time.

If you didn't see anything in the instrument cluster, it's definitely the turn signal reminder.
