9-70 Vehicle Care This could be an early indicator that the air pressure in the tire(s) are getting low and need to be inflated to the proper pressure. Notice: Using non-approved tire sealants could damage the Tire Pressure Monitor System (TPMS) sensors. TPMS sensor damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use the GM approved tire sealant available through your dealer/ retailer. Factory-installed Tire Inflator Kits use a GM approved liquid tire sealant. Using non-approved tire sealants could damage the TPMS sensors. See Tire Sealant and Compressor Kit on page 9‑84 for information regarding the inflator kit materials and instructions. When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument panel cluster. A DIC warning message to check the pressure in a specific tire is also shown on the DIC display screen. The low tire pressure warning light and the DIC warning message come at each ignition cycle until the tires are inflated to the correct inflation pressure. The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as you start to drive. The Tire and Loading Information label, attached to your vehicle, shows the size of your vehicle's original equipment tires and the correct inflation pressure for the tires when they are cold. See Vehicle Load Limits on page 8‑12, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Tire Pressure on page 9‑66. Your vehicle's TPMS can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection on page 9‑73, Tire Rotation on page 9‑73 and Tires on page 9‑58.
