Compass Accuracy

2010 Ford Focus SE, 2D Coupe, StandardSECTION Compass Accuracy

Driving near power lines, or driving in the area of large iron or steel structures can temporarily change the compass heading. If the compass remains inaccurate after driving near such objects, calibrate the compass. Refer to COMPASS CALIBRATIONΒ .

Most geographic areas (zones) have a magnetic north compass point that varies slightly from the northerly direction on maps. This variation is 4 degrees between the adjacent zones and becomes noticeable as the vehicle crosses multiple zones. A correct zone setting eliminates the error. Refer to COMPASS ZONE ADJUSTMENTΒ .
