What is the Vw jetta dashboard symbol that is a car with screw on the side?

IT ACTUALLY MEANS THAT YOUR GAS CAP IS NOT ON PROPERLY. TIGHTEN THE GAS CAP BUT LIKELY THE COMPUTER WILL RUN 2 OR 3 TESTS TO MAKE SURE THAT IT IS PROPERLY ON , SO DEPENDING ON HOW MUCH YOU DRIVE THE CAR IT MAY TAKE A DAY OR SO FOR THE LIGHT TO GO OFF. JUST KEEP CHECKING IT TO MKAE SURE THAT IT REMAINS SECURE.
