Problem with warning bell

I have a Chevrolet Pick Up Year 98 or Izusu that in the absence is the same and when I turn on the engine, the warning bell begins (I think) soon the sound stops, but soon it returns and so on. I need recommendations of how to deactivate it, since listening to the bell at every time is very unpleasant.
Thank you I hope quickly ...

Which warning time? Is one that is heard below the co -pilot's gloveard?, well if so, with some Nissan, check the water level and fill it, warn if it disappeared, if it is the light is more complicated.

Thanks for answering, if it is heard under the glove compartment, I already checked all levels and are fine. The other may be that a sensor is in poor condition. What interests me to know is if I can disconnect the famous bell (pi, pi, pi .....)

I would be the idea of ​​looking for the problem and repairing it, but it is a matter that you look
