On a BMW 1995 525, where is the DSC (dynamic stability control) button located?

Just this morning, I found a new light that came on and is staying ON. The light is a triangle with a circle around it (with an upside down exclamation point inside the triangle). Based on BMW discussions, I now understand that this light has to do with the DSC. However, I don't know where the DSC button is located; thus, cannot turn OFF the light. Can someone help?
