Driver Controls Usually, when something affects the compass readings, the compass will correct itself after a few days of operating your vehicle in normal conditions. If the compass still appears to be inaccurate, a manual calibration may be necessary. Refer to Compass calibration adjustment in this section. Most geographic areas (zones) have a magnetic north compass point that varies slightly from the northerly direction on maps. This variation is four degrees between adjacent zones and will become noticeable as the vehicle crosses multiple zones. A correct zone setting will eliminate this error. Refer to Compass zone adjustment in this section. Compass zone adjustment 1. Determine which magnetic zone you are in for your geographic location by referring to the zone map. 2. Turn ignition to the ON position. 3. Start the engine. 3 2 4 5 1 15 14 13 12 6 7 8 9 1011 4. Locate the reset button on the compass sensor mounted on the base of mirror. 5. Press and hold for six seconds and release. You will see that ZONE appears in the instrument cluster display. 6. Press and release the button until the desired zone number appears. Note: The range of zone values are from 01 to 15 and "wraps" back to 01. 7. The zone will be stored, and the cluster display will return to the ЉnormalЉ mode when the button has not been pressed for 4 seconds. Compass calibration adjustment Perform this adjustment in an open area free from steel structures and high voltage lines. For optimum calibration, turn off all electrical accessories (heater/air conditioning, wipers, etc.) and make sure all vehicle doors are shut. 125 2006 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
