The compass is self-calibrating, which eliminates the need to manually set the compass. However, under certain circumstances, such as during a long distance cross-country trip, it will be necessary to compensate for compass variance and reset the zone through the DIC. See "Setting the Compass" later in this section for more information. OIL LIFE REMAINING: Press the gages button until OIL LIFE REMAINING is displayed. This screen indicates the percentage of oil life in the vehicle's engine that has not degraded. See Engine Oil on page 5-14 for more information. After the oil has been changed in the vehicle, reset the ENGINE OIL MONITOR screen in the options menu. See "Engine Oil Monitor System" under "Options" later in this section. Press the gages button again to advance to the next screen. TRANSMISSION FLUID TEMP: This screen displays this message along with the temperature (F° or C°) of the transmission fluid. Press the gages button again to advance to the next screen. BATTERY: This screen displays the amount of volts the battery is generating. Your vehicle's charging system regulates voltage based on the state of the battery. The battery voltage may fluctuate when viewing this information on the DIC. This is normal. Press the gages button again to advance to the next screen. The buttons on the DIC trip computer are gages, trip odometer, set/reset, options, and fuel.
