Display read stop and put it in park
 

My sister has a 2013 Ram 1500 3.6 SLT. She said that she was driving and then the check engine light came on and the display came says to stop and put it in park. She said it had a slight mist . When she follow instructions the engine light went off and truck act normal and she drove on. Anybody heard of this?

Get it scanned for stored codes and post the codes here.. By "slight mist", I assume you mean slight miss? Always a good idea to proof read before posting to avoid confusion.
