well if it is the "Maintenance Required" light, the amber thing toward the bottom left of the dash cluster, you can just reset it if the car has been maintained. If you do routine maintenance on the car, then just reset the light. Without putting the key into the ignition, hold down the milage/trip reset button and while holding it down, place the key into the ignition and turn it to On/ACC but do not start the car, after a few seconds the light should go off. I think it's somewhere like 5 seconds or so.
