[Chrysler] Forward Collision Detection Warning
A warning showing 2 cars following each other with an exclamation point and arrow beneath one of them could be for the forward collision detection system.
The system is trying to tell you that it has detected a situation where a potential collision may occur and is responding to it through adjusting the brakes, suspension and seat-belts.
If you are seeing this warning light stick on persistently then seek the help of a trained mechanic or Chrysler dealership.
