You can try taking the positive cable off for about 3-secs and check in you owner manual to see if it tell you how and if you do have one try this website www.edmunds.com to see if you can download one for you car.

How do i reset the service engine light soon? It stays on after i have changed the oil and filter and reset the oil life sensor to 100%.


The service engine soon light indicates a problem.
Take the vehicle to AutoZone and have them read the computer code.
They can give you an idea of what the problem is and reset the light for you.
BTW the service is free

The service engine soon light will not go out and oil has just been changed.


The service engine soon light and change oil indicator are 2 different things. The change oil indicator in the information center is reset by pushing the gas peddle all the way to the floor and letting it up all the way with the key in the run position with the engine off.
The service engine soon is a tell tail light letting you know that there is a problem with the way the engine is running. It has nothing to do with preventive maintenance.

My change oil light never goes off even though I had it changed and now my service vehicle soon light is on even though its been running fine


The change oil light needs to be reset after each oil change...some shops are not knowledgeable on how to do this...Your owners manual will instruct you how to reset the oil change light...The service engine soon is a catch all for low fluids and other needs...Be sure to check your oil level again...to clear the service engine soon light, you can disconnect either battery cable for 15 minutes then reconnect...if the service engine stays on...then you need to have your Grand Am checked...Auto Zone does a free diagnostic of check engine light codes...:)

How do i reset the service the service vehicle soon light? I have changed the oil


Turn the ignition to ON, with the engine off. Fully depress and release the accelerator pedal slowly three times within five seconds. The reset is complete when you hear the chimes and the “CHANGE OIL” light goes out. If the light stays on and no chime is heard, you will need to repeat the reset procedure. Turn the key to OFF. If the “CHANGE ENGINE OIL” message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.

Airbag light and service soon light


You need to take this to a shop and have the airbag system repaired as that light is indicating a fault in the airbag deployment system. The service Engine soon light could be nothing more that a reminder to change the oil but is most likely an Oxygen sensor that needs replaced.

Change oil soon light stays on and service engine soon light has come on.


You reset the change oil soon light by a couple of different ways depending on your model. Your owners manual will let you know. Some is by depressing the accelerator when car is not running but in accessories mode on ignition. Others you can reset through the radio. Take a look at your owners manual on this. For the service engine soon light, take it to a autozone and they will run a diagnostic for free. Then they can tell you just what is going on and will have the part to fix it. It is probably an oxygen sensor if it is otherwise running fine. good luck and I hope this helps.

Service Engine soon light stays on but car runs


Probably needs an oil change (if it already hasn't had one) and the light reset. If that doesn't help, take it and have a code scanner hooked up to it, to find out why the light is on.
If there is an autozone or advanced auto near you, go there, and tell them you have an engine light on and need to read the code.
They usually don't charge, other places do.
