What is the purpose of the hidden button on the dashboard of a Kia ProCeed?

I noticed a small, unlabeled button on the dashboard of my Kia ProCeed. What does it do?

That button is actually for activating the High Beam Assist feature. It allows for automatic switching between high and low beams based on surrounding traffic.

It's for the rearview camera. Pressing it will activate the camera, providing a clear view of what's behind your car while you're reversing.

That button is for activating the Lane Keep Assist feature. It helps you stay in your designated lane by gently steering the car back into position if you start drifting.
