Magnetic or metallic objects placed in, on or near the vehicle may also affect compass accuracy. 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 zone/calibration adjustment. 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/calibration adjustment. 23 2010 Crown Victoria (cro) Owners Guide, 2nd Printing USA (fus)
