Instruments and Controls This light comes on when the StabiliTrak system is turned off. If StabiliTrak is off, the Traction Control System (TCS) is also off. If the StabiliTrak and TCS are off, the system does not assist in controlling the vehicle. Turn on the TCS and the StabiliTrak systems and the warning light turns off. See Traction Control/Electronic Stability Control on page 9-33. If the light does not come on, have the vehicle serviced by your dealer. If the system is working normally, the indicator light turns off. If the light is on and not flashing, the TCS, and potentially the StabiliTrak system have been disabled. A DIC message may display. Check the DIC messages to determine which feature(s) is no longer functioning and whether the vehicle requires service. If the indicator/warning light is on and flashing, the TCS and/or the StabiliTrak system is actively working. See Traction Control/Electronic Stability Control on page 9-33. 5-23 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 5-37. 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 10-55. When the Light Flashes First and Then Is On Steady If the light flashes for about a minute and then stays on, there may be a problem with the TPMS. If the problem is not corrected, the light will come on at every ignition cycle. See Tire Pressure Monitor Operation on page 10-57.
