Test B - Calibrating the Compass

The compass in the mirror is an "autocal" compass. This means the mirror will automatically calibrate itself so that the unique magnetic fields in each vehicle do not cause the mirror to display the wrong direction. When the compass is calibrating a "C" will be displayed. The mirror will calibrate itself during your normal driving routine. When calibration is complete the "C" in the display will change to the correct directional heading. Once the mirror is calibrated it will not normally need to be recalibrated. If it does need to be recalibrated it will occur automatically without any input from the driver. Turning the mirror or the vehicle off will not cause the calibration to be lost.

If desired the compass can be manually recalibrated as follows:

1. If the "C" is already being displayed, simply drive the vehicle slowly (5 mph or less) in a 360 degree circle until the display reads a compass direction. This will probably calibrate the compass quicker than it would calibrate automatically.

2. If the "C" is not already being displayed turn the vehicle ignition on and the compass mirror on. Depress the calibrate switch by inserting the end of a paper clip in the hole on the bottom of the mirror and hold it for 10 seconds until the letter "C" appears in the display. The display will show a number first, but keep holding it until the letter "C" appears. Once the letter "C" appears in the display, drive the vehicle slowly (5 mph or less) in a 360 degree circle until the display reads a compass direction.
