Electronic Compass: Notes

The compass display is contained in the front display interface module (FDIM). For the FDIM, refer to INFORMATION AND ENTERTAINMENT SYSTEMS article. For early build vehicles, the compass module is attached to the interior rear view mirror and is replaced separately from the mirror. For late build vehicles, the compass module is integrated into the interior rear view mirror. Refer to REAR VIEW MIRRORS article. The MODE button that allows the driver to operate the calibration and zone setting procedures is located on the top left of the compass module for early build vehicles and on the center bottom of the interior rear view mirror for late build vehicles. The vehicle heading is displayed as a 1 or 2 character display located in the lower left hand side of the FDIM and indicates the current direction of the vehicle (N, NE, E, SE, S, SW, W, or NW). The compass continuously recalibrates 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 positions. 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 will turn off as soon as the key is turned to the OFF or ACC positions.
