I have a 2001 impala, and after airing up your tires, you have to reset the warning light. I don't know how yours is set up, but mine is set up through the radio. You have to turn the radio off and hold the display button down until it gives you the settings options and then just scroll thru until you get to the tire setting and tell it to reset. It won't come on again until your tires are low again.
