Up-Shift 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 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 or Manual Transmission for more information.
