Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice: If the engine is operated with the tachometer
in the shaded warning area, the vehicle could be
damaged, and the damages would not be covered by
the vehicle warranty. Do not operate the engine with
the tachometer in the shaded warning area.
The CTS-V tachometer has tracer lights that follow the
movement of the tachometer indicator. The tracer lights
can be turned off in the DIC Vehicle Customization.
See DIC Vehicle Customization on page 3-72 for more
information.
For the CTS-V, the tracer lights also flash when it is
time to up-shift to avoid the engine speed limit.
See Automatic Transmission Operation on page 2-36
or Manual Transmission Operation on page 2-40
for more information.
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.
