An accident sign showing on the dashboard and HID
I have a question about the dashboard warning sign. Today, when I drive in the highway, a warning sign, 'Accident', suddenly showed up on my dashboard. My car is 2011 x3 35i. At that time, I did not feel anything wrong about my car. About 2 or 3 mins later, the warning sign turned off itself. When I got home, I checked my car again. Everything looks good. Did anybody see that sign? It is show up as the word 'Accident' and a small pic about a car hit another car. I looked up the user manual and found no hint about this. Did anybody know what is going on? Thank you very much.
