I own a 1999 BB6 and underneath the speedometer, there's a tiny light thats a square, and it should be green when lit, but it is a yellow-orange color. What does this mean. I checked all my fluids(oil, tranny,power steering, coolant, etc.)

 

Thats the maintenance reminder, reset it with your key (the little button next to it) it changes color every 7,500 miles. it would be in your owners manual (if you have one). its no big deal
