2010 GMC Savana 2500 Cargo Owner's Manual - Page 168

Speedometer and Odometer The speedometer shows the vehicle speed in both miles per hour (mph) and kilometers per hour (km/h). The odometer shows how far the vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). This vehicle has a tamper resistant odometer. The digital odometer will read 999,999 if it is turned back. 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. Trip Odometer The trip odometer can show how far the vehicle has been driven since the trip odometer was last set to zero. Press the Trip/Fuel button on the Driver Information Center (DIC) switch to display the trip odometer and the regular odometer information. See DIC Operation and Displays on page 4-38 for more information on resetting the trip odometer. To display the odometer reading with the ignition off, press the Trip/Fuel button on the Driver Information Center (DIC) switch. 4-22
