Compass: Description and Operation
Electronic Compass
Vehicles With Navigation
The compass signal originates from the Global Positioning System (GPS) signal. No calibration or zone adjustment is available, as the compass heading
is based on the GPS signal. Refer to Radio, Stereo, and Compact Disc for information on the GPS signal.
Vehicles Without Navigation
The compass signal originates from the compass module, which is integrated into the auto-dimming interior mirror.
The compass reading is incorporated into the Front Display Interface Module (FDIM).
The buttons that allow the driver to operate the calibration and zone setting procedures is located below the FDIM. The vehicle heading is displayed as a
1 or 2 character display located in the lower LH side of the FDIM and indicates the current direction of the vehicle (N, NE, E, SE, S, SW, W, or NW).
The compass continuously re-calibrates due to changes in the magnetic field and remains accurate during most driving conditions. The compass display
is on with the key in the ON or START position. When the key is first turned to the ON or START position, there is a momentary delay of
approximately 6 seconds before the compass display illuminates. If the battery saver has been activated and the key is turned to ON or START, the
momentary delay before the compass display illuminates is approximately 3 seconds. The compass display turns off as soon as the key is turned to the
OFF or ACC position.
Compass Accuracy (Without Navigation)
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.
