Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 vehicle heading is displayed as a 1 or 2 character display located in the upper RH 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.
On Fusion/Milan, the Front Controls Interface Module (FCIM) buttons that allow the driver to operate (change) the calibration and zone setting procedures are located below the FDIM.
On MKZ, the buttons that allow the driver to operate (change) the calibration and zone setting procedures are located on the FDIM.
The compass display is on with the ignition in the ON or START position. When the ignition 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 ignition 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 ignition is turned to the OFF or ACC position.
