Instruments and Controls 5-25 Up-Shift Light StabiliTrak® OFF Light Traction Control System (TCS)/StabiliTrak® Light The vehicle may have an up-shift light. It indicates when to shift to the next higher gear for best fuel economy. See Manual Transmission on page 9￿32 for more information. For the CTS-V, the tracer lights function as a performance up-shift light. The tracers flash to indicate when to shift to the next higher gear to avoid the engine speed limit. See Automatic Transmission on page 9￿28 or Manual Transmission on page 9￿32 for more information. This light comes on briefly while starting the engine. If it does not, have the vehicle serviced by your dealer. 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 TCS is 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 System (TCS) on page 9￿40 and StabiliTrak® System on page 9￿41. The StabiliTrak or Traction Control System (TCS) indicator/warning light comes on briefly when the engine is started. 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.
