Why is my service vehicle soon light coming on? on 2004 Saturn Vue

I recently took my car in to get an oil leak fixed & AC compressor replaced and now my service vehicle soon light is on. It is the only light that comes on and it only comes on after you get down the road a little ways, not right when you crank it up.

go back and have them scan codes and see if its related to what work they did.
