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 returns
to normal when engine speed is lowered.
For the CTS-V, the tachometer tracer lights flashes prior
to reaching engine speed limit. The tracer lights also
flash on automatic transmission vehicles while in
the DSC or Tap Shift modes.
