The mirror can be calibrated in one of two ways: 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. 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. Use the COMPASS side of the button located at the bottom of the mirror. Press and hold COMPASS until a zone number appears in the display. 2. Find your current location and variance zone number on the following zone map. 3. Press COMPASS on the bottom of the mirror until the new zone number appears in the display. After you stop pressing the button, the display will show a "C" and will need recalibration. 2-52
