2007 Cadillac CTS-V Owner's Manual - Page 191

If your vehicle has to have a new odometer installed, the new one may read the correct mileage. This is because your vehicle's computer has stored the mileage in memory. While the Driver Shift Control (DSC) feature is active, the odometer will change to show the gear range. See Automatic Transmission Operation on page 118 for more information. Tachometer This gage indicates the engine speed in Revolutions Per Minute (RPM). Notice: If you operate the engine with the tachometer in the shaded warning area, your vehicle could be damaged, and the damages would not be covered by your warranty. Do not operate the engine with the tachometer in the shaded warning area. Trip Odometers The trip odometer can record the number of miles or kilometers traveled for up to two trips. The trip odometer is part of the Driver Information Center (DIC), for more information see Status of Vehicle Systems on page 219. For vehicles that have the navigation system, see your Navigation System manual for more information. Engine Speed Limiter This feature prevents the engine from operating at too many revolutions per minute (rpm). When the engine's rpms are too high, the throttle is closed to reduce speed. If this is not sufficient, then the fuel supply to the engine will be limited. When the rpms return to normal, the fuel supply will return to normal. This helps prevent damage to the engine. 191
