I swear, I have owned so many German cars over the years and all of the little warning lights and signals are so full of crap that I can't even go into detail here. Screw the warning lights...pretend as though your German Mercedes/BMW/Audi/Porcshe is a Ford and look it at that way.... if it's leaking oil, fix it....if it needs coolant, do it...if it needs brakes then take care of it....these cars are simply cars...a Mercedes is exactly the same as a Chevrolet in principle...same thing...don't be confused and overwhelmed.....by the name...screw it...they are all just cars....
