Engine Speed Limiter
This feature prevents the engine speed from reaching an unsafe level. If the level is too high, the throttle closes or limits the fuel supply until the engine speed returns to a safe level. Throttle operation and fuel supply return to normal when engine speed is lowered.
For the CTS-V, the tachometer tracer lights flash prior to reaching engine speed limit. The tracer lights also flash on automatic transmission vehicles while in the DSC or Tap Shift modes.
