Instruments and Controls 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 9‑50, Traction Control System (TCS) on page 9‑48 and Ride Control System Messages on page 5‑27 for more information. 5-19 Tire Pressure Light For vehicles with a 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 5‑28 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 10‑56 for more information. When the Light Flashes First and Then is On Steady This indicates that there may be a problem with the Tire Pressure Monitor System. The light flashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor Operation on page 10‑60 for more information.
