Salam everyone! Can anyone tell me what does this mean in the display? It has a spanner icon on it. When we bought the car it had the number "5". Some days back it was "2". Today it was showing "--------". I thought it was for showing that your car needs maintenence such as oil change, filter cleaning. As the oil filter change was due, I changed it today, hoping to see it go back to "5". But it remained at "--------". Can anyone else tell or guess what it could be? :-/
