D Drive the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction, or D Drive the vehicle on your everyday routine and after several turns the compass will become calibrated and will display a direction. Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if you live outside zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth's magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings. To adjust for compass variance: 1. Press and hold the COMP button, located at the bottom of the mirror, for three seconds until a zone number appears in the display. 3. Press the COMP button on the bottom of the mirror until the new zone number appears in the display. After you stop pressing the switch in, the display will show a compass direction within a few seconds. 2-55
