Compass: Adjustments

COMPASS VARIATION ADJUSTMENT

Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, the compass variance must be set.

ZONE METHOD

Variance Settings:

1. Using the Variance Settings map, find your geographic location and note the zone number.
2. Turn the ignition switch to the On position. Press and hold the Zone/Calibration (left reading lamp button) button for 5 to 10 seconds. The Zone symbol should be illuminated.
3. Releasing the Zone /Calibration button while the ZONE symbol is illuminated will cause the mirror to enter the zone display mode.
4. The current variance zone will now be displayed. To change the zone, press the Zone/Calibration button until the correct zone is displayed. Wait for 5 seconds.
5. After five seconds, the displayed zone will automatically be set in the mirror memory and normal operation will resume.
6. Confirm that the correct directions are now indicated by the compass.
