Compass Calibration Press the on/off button for eight seconds to activate the compass calibration mode. The letter C will be displayed in the compass window on the mirror. 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 indicates a direction or until C is no longer displayed in the compass window. D Drive the vehicle on your everyday routine. 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. 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, such as during a long distance cross-country trip, it will be necessary to adjust for compass variance. To adjust for compass variance do the following: 1. Find your current location and variance zone number on the following zone map. 2. Make sure the compass is in calibration mode. See "Compass Calibration" in the Index. Press the on/off button to display the zone number. 3. Scroll through the zone numbers that appear in the compass window of the mirror. Once you find your zone number in the window, release the on/off button. After about four seconds, the mirror will return to the compass display, and the new zone number will be set. Compass calibration may be necessary. See "Compass Calibration" in the Index. 2-51
