I’ve seen that menu and turned it down to the lowest volume. Just wish I could turn the sound off without losing the lane assist. My wife’s Mazda CX-5 has a way to turn the volume off but keep the feature on. Was just hoping Kia had something similar.Main menu (between speedo and tach) has warning alert volume levels. It’s something like driver assist, then you go into it and you can set all kinds of things exactly how you want them.
You can either play with it like I have, or read the owners manual for the exact menu path.
