I believe you are referring to the tire pressure warning light. If so - make sure that all tires (including the spare) are inflated to the factory recommended pressure (see sticker on drivers door jamb). Then, on the drivers side, slide your hand along the underside of the dash panel. Just about underneath where the steering column passes through the dash you will feel a little push button. With the ignition turned ON depress this button and hold for 10 seconds, and it should reset the tire pressure warning system. BTW: These instruction are also included in the Owners Manual.
