Engine Oil Symbol in Nav system

[vjk1245]

A symbol that looks like oil is required or should be added pops up in the nav display when i start the car.  There are no warning lights on the dash.  I checked the oil level and it is full and the oil was changed 3000 miles ago. The oil filter was also changed.  Below the symbol it says to contact the dealer which I don't want to do until I know more.  The manuals don't appear to show this symbol.  I'd like to know what it means and if serious.  Thanks.
