Compass Calibration




Compass Calibration

NOTE: This procedure is only applicable to vehicles without navigation.

1. NOTE: For optimum calibration, drive to an open, level location away from large metallic objects or structures. Switch off all non-essential electrical accessories (heated rear window, heater fan, A/C, map lamps, and wipers) and make sure all doors are closed.

Start the vehicle.

2. NOTE: The vehicle remains in the CAL mode until the compass has been successfully calibrated.

NOTE: While holding the Front Controls Interface Module (FCIM) (Fusion/Milan) or Front Display Interface Module (FDIM) (MKZ) 7 and 9 buttons down, the compass display first enters the ZONE setting mode (after 5 seconds) and then after another 5 seconds (10 seconds total), the compass display enters the CAL mode.

Press and hold (for approximately 10 seconds) the 7 and 9 buttons until the CAL indicator appears in the display, then release the buttons.

3. NOTE: If the CAL indicator does not turn off after the vehicle is driven in a circle at least 5 times, repeat the procedure.

Drive the vehicle slowly at less than 5 km/h (3 mph) in a continuous circle until the CAL indicator disappears from the display and the compass heading is shown.

4. If the CAL indicator does not turn off after driving in a circle at least 5 times (and the procedure has been repeated at least once), install a new compass module (integral to the auto-dimming interior mirror).
