Blank Screen Shows a blank screen. Pressing the C/T button returns to the Compass and Temperature display. Pressing the STEP button returns you to the Average Miles per Gallon display. Automatic Compass Calibration This compass is self-calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After completing three 360 degree turns in an area free from large metal or metallic objects, the CAL symbol will turn off and the compass will function normally. Manual Compass Calibration If the compass appears erratic and the CAL symbol does not appear, you must manually put the compass into the "Calibration" mode. To Put Into a Calibration Mode Turn on the ignition and set the display to "Compass/ Temperature." Press and hold the RESET button (more than 10 seconds) to change the display between VARIANCE (compass variance) and CAL (compass calibration) modes. When the CAL symbol is displayed complete three 360 degree turns in an area free from large metal objects or power lines. The CAL symbol will turn off and the compass will function normally. Compass Variance is the difference between magnetic north and geographic north. In some areas of the country, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set according to the Compass Variance Map. 3
