Hi. I’m 2 weeks into owning my new 2020 Ioniq Limited. I’m truly enjoying this car. Today, I was following a car at what I think was a safe distance. The car made an erratic right turn merge ahead of me. My car chimed a few times and the green half circles (to right of eco/charge and to left of gas/battery) turned red and started flashing. I cannot find these half circles referenced in my manual. What are they called and what is their primary function and system they indicate for? Thanks!!
