Press the unlock button on the key fob 3 times in quick succession, then hold the button down and the windows will start to roll down.

I just found this out today and thought it would be a good tip with the current heat we're dealing with. I searched this subreddit and found only one or two old posts mentioning, so a lot of people might be unaware of this feature.

I happened to be walking by my coworker's truck today when all the windows suddenly went down without him in it. I asked him about it and he said he did it with the key fob, and my car probably has it too. I looked it up and sure enough, the CX-50 has this feature as well. Pretty nifty!
