1990 964 with two dash lights on cant figure out what to do?

Hey guys I just bought my first Porsche and guess what it didnt come with a manual LOL, So as you can guess I am figuring it out as I go HAHA. But my question is that not every time I start up the car but sometimes happens on start up too the what looks like the AWD light and Brake Light come on always together sometimes it takes a while for these lights to come on but they in fact always come on? What do they mean and what do I have to look at to determine the problem. The Brakes on the car are in good shape so I dont think its the pads. Thanks Clueless in Boston
