Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when thesystem is not operating properly. The TPMSmalfunction indicator is combined with the low tirepressure telltale. When the system detects amalfunction, the telltale will flash for approximatelyone minute and then remain continuouslyilluminated. This sequence will continue uponsubsequent vehicle start-ups as long as themalfunction exists.When the malfunction indicator is illuminated, thesystem may not be able to detect or signal lowtire pressure as intended. TPMS malfunctions mayoccur for a variety of reasons, including theinstallation of replacement or alternate tires orwheels on the vehicle that prevent the TPMS fromfunctioning properly. Always check the TPMSmalfunction telltale after replacing one or moretires or wheels on your vehicle to ensure that thereplacement or alternate tires and wheels allowthe TPMS to continue to function properly.Please note that the TPMS is not a substitute forproper tire maintenance, and it is the driver’sresponsibility to maintain correct tire pressure,even if under-inflation has not reached the level totrigger illumination of the TPMS low tire pressuretelltale.A Tire and Loading Information label, attached toyour vehicle, shows the size of your vehicle’soriginal equipment tires and the correct inflationpressure for your vehicle’s tires when theyare cold. See Loading Your Vehicle on page 349for an example of the Tire and LoadingInformation label and its location on your vehicle.Also see Inflation - Tire Pressure on page 431.Your vehicle’s TPMS can warn you about a low tirepressure condition but it does not replace normaltire maintenance. See Tire Inspection andRotation on page 438 and Tires on page 421.Notice: Your vehicle has a Tire PressureMonitor System (TPMS). Use only theGM-provided tire sealant. Other liquid tiresealants may damage the tire pressuresensors.435
