Cadillac 2007 CTS, Owner'S Manual, Page: 191 / 518

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.
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.
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.
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.
