Mustang V8-4.6L (2009)
Compass: Description and Operation
Electronic Compass
The compass display and module are an integral part of the interior rear view mirror. A 1 or 2 character display located in the upper right hand side of
the mirror indicates the current direction of the vehicle (N, NE, E, SE, S, SW, W, NW). The compass continuously recalibrates due to changes in the
magnetic field and remains accurate during most driving conditions. The compass display can be turned off and on by pressing the switch on the mirror.
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 Calibration See: Adjustments/Compass Calibration.
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 Adjustment See: Adjustments/Compass Zone Adjustment.
