5-22 Instruments and Controls If the light does not come on or stays on, have the vehicle serviced by the dealer. If the system is working normally, the indicator light turns off. If the light comes on and stays on while driving, and a message displays in the Driver Information Center (DIC), have the vehicle serviced by the dealer. See Ride Control System Messages on page 5‑38 for more information. If the light flashes while driving, this means that StabiliTrak or TCS is assisting in controlling the vehicle. See StabiliTrak® System on page 9‑44 for more information. Press and briefly hold the TCS/ StabiliTrak button to turn off the StabiliTrak system; the StabiliTrak Off light comes on and a message appears in the Driver Information Center (DIC). If the StabiliTrak/TCS system is off, the system does not assist in controlling the vehicle. Turn on the StabiliTrak/TCS system and the indicator light turns off. See StabiliTrak® System on page 9‑44, and Ride Control System Messages on page 5‑38 for more information. Tire Pressure Light For vehicles with the Tire Pressure Monitor System (TPMS), this light comes on briefly when the engine is started. It provides information about tire pressures and the TPMS. When the Light Is On Steady This indicates that one or more of the tires are significantly underinflated. A Driver Information Center (DIC) tire pressure message may also display. See Tire Messages on page 5‑39. Stop as soon as possible, and inflate the tires to the pressure value shown on the Tire and Loading Information label. See Tire Pressure on page 10‑53.
