VEHICLE CARE 301example of the Tire and LoadingInformation label and its location.Also see Tire Pressure 0 297.The TPMS can warn about a low tirepressure condition but it does notreplace normal tire maintenance. SeeTire Inspection 0 303, Tire Rotation0 303 and Tires 0 290.CautionTire sealant materials are not allthe same. A non-approved tiresealant could damage the TPMSsensors. TPMS sensor damagecaused by using an incorrect tiresealant is not covered by thevehicle warranty. Always use onlythe GM approved tire sealantavailable through your dealer orincluded in the vehicle.Factory-installed Tire Inflator Kits usea GM approved liquid tire sealant.Using non-approved tire sealantscould damage the TPMS sensors. SeeTire Sealant and Compressor Kit 0 311for information regarding the inflatorkit materials and instructions.TPMS Malfunction Light andMessageThe TPMS will not function properly ifone or more of the TPMS sensors aremissing or inoperable. When thesystem detects a malfunction, the lowtire pressure warning light flashes forabout one minute and then stays onfor the remainder of the ignition cycle.A DIC warning message also displays.The malfunction light and DICwarning message come on at eachignition cycle until the problem iscorrected. Some of the conditions thatcan cause these to come on are:. One of the road tires has beenreplaced with the spare tire. Thespare tire does not have a TPMSsensor. The malfunction light andDIC message should go off afterthe road tire is replaced and thesensor matching process isperformed successfully. See “TPMSSensor Matching Process” later inthis section.. The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. The malfunctionlight and the DIC message shouldgo off after successfullycompleting the sensor matchingprocess. See "TPMS SensorMatching Process" later in thissection.. One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching process isperformed successfully. See yourdealer for service.. Replacement tires or wheels donot match the original equipmenttires or wheels.
