To calibrate the compass:
Stop the vehicle in a large open area, safely out of traffic and away from steel structures and high-tension electrical wires.
Start the vehicle.
Note
- For best calibration results, switch off all electrical equipment in the vehicle (climate system, windshield wipers, audio system, etc.) and make sure that all doors are closed.
- Calibration may not succeed or be incorrect if the vehicle's electrical equipment is not switched off.
Using a pen, paperclip or similar object, press and hold the button on the underside of mirror for approx. 3 seconds until the number of the current magnetic zone is displayed.
Press the button on the underside of mirror repeatedly until the desired magnetic zone (1–15) is displayed (see the map of magnetic zones).
Wait until C is again displayed in the mirror or hold the button on the underside of mirror for approx. 6 seconds until C is displayed in the mirror.
Drive slowly in a circle at a speed of no more than 6 mph (10 km/h) until a direction is displayed. This indicates that calibration is complete. Drive around in a circle an additional two times to fine-tune the calibration.
Vehicles with an electrically heated windshield:* if C is displayed when the heating function is activated, perform step 6 with the heating function on.
Repeat the calibration procedure if necessary.
