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.
Engine Oil Pressure Gage
United States
Canada
For vehicles with an engine oil
pressure gage. It shows the engine
oil pressure in psi (pounds per
square inch) when the engine is
running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine
speed, outside temperature and oil
viscosity, but if readings are outside
the normal operating range, the oil
pressure light will come on. See
