Operation
Eight different directions are shown with the abbreviations: N (north), NE (north east), E (east), SE (southeast), S (south), SW (southwest), W (west) and NW (northwest).
Calibration
North America is divided into 15 magnetic zones and the compass will need to be calibrated if the vehicle is driven into a new one (see the magnetic zones on the map in the following section "Selecting a magnetic zone"). To do so:
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.
Press and hold the button for 3 seconds until the number of the current magnetic zone is displayed.
Press the button repeatedly until the number of the desired magnetic zone (1-15) is displayed. See the magnetic zones on the map in the following section "Selecting a magnetic zone").
Wait until C is again 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 7 with the heating function on. See also Max. defroster and electrically heated windshield* for additional information about the heated windshield.
Repeat the calibration procedure if necessary.
Selecting a magnetic zone
The earth is divided into 15 magnetic zones. The correct zone must be selected for the compass to work correctly.
Put the ignition in mode II.
Using a pen or similar object, press and hold the button on the rear side of mirror for at least 3 seconds. The number for the current area will be shown.
Press the button repeatedly until the number for the required geographic area (1 – 15) is shown.
The display will revert to showing the compass direction after several seconds.
