What are you seeing after you follow the procedure? Does the
light stay on steady still, or does it flash about 5 times when you
start the engine? I've noticed that on some vehicles, the light
goes out and stays out, and on other's the light will flash a number
of times, go out....but then repeat this on the next key cycle.
Eventually the light seems to go out.
I guess you may need to try it a few more times.
What you should see is the light (Change oil soon)
flashing about 5 times "after" you pressed the
gas to the floor 3 times with the key on.
The service manual does mention that if
the light cannot be reset, the instrument
cluster needs to be replaced. You might
want to see the dealership if you cannot
reset the light.
I have found that it is much easier to reset when the engine is cold. I have
tried two or three times in a row to reset it right after driving and would
fail each time. When the engine is cold, it seems to reset first time every
time. My 01 3500 Duramax isn't as bad about needing a cold engine as my 98
Lumina which requires a cold engine consistently.
