Instruments and Controls 5-17 Traction Control System (TCS)/StabiliTrak® Light If the StabiliTrak system and TCS light comes on and stays on while driving and a TRACTION FAULT or SERVICE STAB SYS message displays on the DIC, the vehicle needs service. The light also comes on steady when the StabiliTrak system and/or TCS are turned off. The DIC also displays a TRAC OFF and/or STAB SYS OFF message. If the TCS is off, wheel spin is not limited. If the StabiliTrak system is off, the system does not assist the driver with directional control of the vehicle. The light turns off when the TCS and StabiliTrak system are turned back on. See StabiliTrak® System on page 9‑47, Traction Control System (TCS) on page 9‑46 and Ride Control System Messages on page 5‑25 for more information. Tire Pressure Light The StabiliTrak and Traction Control System (TCS) indicator/warning light comes on briefly while starting the engine. If it does not, have the vehicle serviced by your dealer. If the system is working normally the indicator light then goes off. The light flashes while the StabiliTrak system and TCS are working to assist the driver with directional control of the vehicle in difficult driving conditions. 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 tire pressure message can accompany the light. See Tire Messages on page 5‑26 for more information. 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 10‑52 for more information.
