5-12 Instruments and Controls If the vehicle needs a new odometer installed, it must be set to the mileage total of the old odometer. If that is not possible, then it must be set at zero and a label must be put on the driver door to show the old mileage reading when the new odometer was installed. Press the 3 on the Driver Information Center (DIC) switch to display the trip odometer and the regular odometer information. See Driver Information Center (DIC) on page 5‑27 for more information on resetting the trip odometer. To display the odometer reading with the ignition off, press the 3 on the Driver Information Center (DIC) switch. If the vehicle has a diesel engine, see the Duramax diesel supplement for more information.

The digital odometer will read 999,999 if it is turned back. Trip Odometer The trip odometer can show how far the vehicle has been driven since the trip odometer was last set to zero.
