i have a 98 v6 camaro and there is a a button in it that says SGS right beside the fog light button and i was just wondering what it dose

 

Just in case you havent got a reply yet that SGS button is for Second Gear Start, it comes in handy in the rain because the car will start in 2nd gear and you wont spin tires, but it really bogs down the car so I never use it.
