I have tried looking up in the owners manual for the meaning of a warning symbol that have been popping up sporadically. It is not listed in the manual. The symbol is a white circle with two cars next to each other. One car is black which is the left car and the other one is a red car which is on the right. Can someone please explain what does that warning light mean ?

 

It's a no passing / no overtaking indicator.
