Front Impact Sensor (FIS): Description
WARNING: This page is about a different car, the 2005 Kia Spectra5, 2005 Kia Spectra, and 2004 Kia Spectra. However, it is still accessible from the selected car via links, so may be relevant.
The Front Impact Sensor (FIS) is installed in the radiator support upper-member. It is a remote sensor that provides accelerometer data to the advanced restraint control module to determine if the severity of a frontal impact event warrants a single-stage or dual-stage frontal airbag deployment.
