There is a tank that is along the frame rail and it hold DEF (diesel Exhaust Fluid) when the tank is almost empty, you get that message to fill it. 5.3 gallons is what it holds and it gets 1300 miles to the gallon.

2000 oldsmobile alero exhaust problem.

If you can tell where the sound is coming from. Look for any smoke venting out. It maybe that the exhaust manifold gasket is going bad. This will cause exhaust to escape from the engine before the tail-pipe. If this is the case, it will not pass SMOG. Could be dangerous for you health as well.
If this is the case, you should be able to hear the gas escape when giving it some gas in Park. Could be the muffler or any part of the exhaust depending on where it is coming from.

Service vehicle soon light is on, scanner at gm dealer read no codes. what all sensors activate this light. aso trac light is on. traction button(in stupid place) doesn't work

ok there is a difference between the check engine light and service vehicle soon light. The service vehicle soon light comes on when a bulb is out on the daytime running lights. Check your bulbs if there is one out and you put a new one in it will most likely take car of problem.
