The purpose of the TPMS on Your 2013 FIAT 500 is to warn You that one or more tires is under-inflated which could produce premature tire wear, tire failure, and unsafe driving conditions. To perform a reset of the TPMS only takes a few moments. First, turn the ignition to the "On/Run" position and then use the "Menu" button to select "Vehicle Information." Scroll to the "Tire Pressure" menu
