Once the tire pressure is at the proper level, the light will go off. So follow your manual.
If the pressure is low, tired need to be serviced...
I took my car to the dealership to ask them about why was the tire pressure low and the light came on in the morning. But then I thought, it just turned cold and the pressure in my tires was cold also. So that is what made the pressure gage come on, but when I began to ride down the ride, the light went off. So, it might be a good idea to take it to let them check it out, then you will know for sure the next time it happens.
