1. Calibrating the compass
The digital compass must be calibrated manually upon initial operation of the vehicle at the dealer's and after the inside mirror has been renewed.
Manually calibrate compass:
- Switch on the ignition
- Press the control button until "C" for calibration appears.
- Start the vehicle.
- Drive in a circle 2 to 3 times at a maximum of 7 km/h until a direction is displayed (calibration to the vehicle's magnetic field). The circle must be at least twice the vehicle's turning circle.
The earth's magnetic field can be deflected, e.g. by underground railway lines. A strongly deflected magnetic field will lead to calibration errors. If the digital compass displays an incorrect reading, check the calibration.
The system can calibrate itself automatically. It will automatically compensate for a slight change in the vehicle's magnetic field. If it is not possible to carry out adequate calibration within 5 minutes, the compass switches to the mode for manual calibration "C". This occurs if the calibration value deviates significantly from the value measured by the magnetic field sensor (more than the earth's magnetic field, approx. 180 milligauss). After driving in a circle or cornering a few times, the digital compass is operational again.
