I just got a call my my facilities manager. She said that my windows were down and it was raining. Yes, I had been playing with my remote.
This quote from the manual explains it:
Remote Open Window Featuree
This feature allows you to remotely lower both front door
windows at the same time. To use this feature, press and
release the UNLOCK button on the RKE transmitter and
then immediately press and hold the UNLOCK button
until the windows lower to the level desired or until they
lower completely.
Apparently, there's no remote close feature, which would be more useful in my opinion.
