Compass Variance Adjustment
COMPASS VARIANCE ADJUSTMENT
Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and geographic north. In some geographic
locations, the difference between magnetic and geographic north is great enough to cause the compass to give inaccurate readings. To optimize compass
accuracy, the compass variance should be properly set according to the compass variance map zone for the region that the vehicle is in.
To set the compass variance:
1. Using the Variance Settings map, find your geographic location and note the zone number.
2. Turn the ignition switch to the On position.
3. Continue to depress and release the STEP button (33) until the "Personal Settings" menu is displayed in the Electronic Vehicle Information Center
(EVIC) display (32).
4. Once in the "Personal Settings" menu depress and release the STEP button (33) several times until "Compass Variance" is displayed. The
"Compass Variance" message and the current variance zone number will be displayed. The default variance zone is 8.
NOTE: During programming, the Zone value will wrap around from Zone 15 to Zone 1.
5. To change the zone, press and hold (longer than two seconds) the STEP button to increment the variance one step. Repeat as necessary, with
individual long (longer than two seconds) STEP button presses for each increment, until the desired variance is achieved.
