Hey all, still figuring out my new S4, but what is side assist supposed to do? Pretty sure my car has it, I have the lights on my side mirrors which have a brightness adjustment in the MMI. THere is also a button on the a-pillar of my driver side, and when I push it the lights come on for a sec and go out. Is that how side assist it turned on? I have never seen those lights come on at any point other than when I press that button or adjust brightness, just wondering what they should be doing? Should they come on when I attempt to change lanes and someone is in my blindspot?
