On my 2022 cx-5 this works with the unlock button. Press unlock 3 times, hold on 4th until windows are down.

 

Yes, thanks, but does it matter how quickly you do it?

 

It's pretty flexible. I can press really fast then hold or about 3 times then hold 4th within about 3 seconds. When I let up on the hold the windows stop going down. I can't say ive ever failed and use it all the time in the summer at the beach.

 

Thanks, that's how it was on our 6! I wonder why it does not always work on ours. It's almost as if the car has to learn how to do it! Funny though that our salesman had never heard of this feature!
