Thank you! Yes I - I finally figured it out. I've never had to turn on the emergency lights and when I reached up to put my sunglasses in the case above the rear view mirror, they fell and hit the button. There are so many things about the Touring Ascent that are so much different than the Touring Forester that I traded for it, that I actually have my owner's manual with all sorts of sticky tabs to look things up.There is a red triangle on a button directly above your radio. Try pressing that.
What I've found useful is to download the pdf manual under Support and Resources in the My Subaru website. Of course you can search, but another nice feature is clicking on a referenced page takes you there. Once you're done there, you can go back by Alt(left arrow)....I actually have my owner's manual with all sorts of sticky tabs to look things up.
