Variance Settings

NOTE:

If the vehicle is taken on long trips into a new variance zone the compass function may be effected. Compass variance will need to be updated to the new zone number to function properly.

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:

-- Using the variance settings map, find your geographic location and note the zone number.

-- Turn the ignition switch to the ON position.

-- Depress the instrument cluster button for approximately 10 seconds until the current variance zone is displayed.

NOTE:

The default for the compass variance from the factory is 8. During programming, the zone value will wrap around from zone 15 to zone 1.

-- To change the zone, press and hold (longer than two seconds) the instrument cluster button to increment the variance one step. Repeat as necessary, with individual long (longer than two seconds) instrument cluster button presses for each increment, until the desired variance is achieved. When the correct zone is displayed, wait approximately 15 seconds. The instrument cluster will store the new variance value in memory and the compass will resume normal operation.

-- Confirm that the correct directions are now indicated by the compass.

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.

NOTE:

If the vehicle is taken on long trips into a new variance zone the compass function may be effected. Compass variance will need to be updated to the new zone number to function properly.

NOTE:

The default for the compass variance from the factory is 8.

-- Using the Variance Settings Map, find your geographic location and note the zone number.

-- Turn the ignition switch to the ON/RUN position. Press and release the SCROLL push buttons (5 or 6) until "System Set-up" is displayed and highlighted.

-- Press and release the STEP push button (3) to open the menu.

-- Using the scroll buttons, scroll through until " Compass Variance" is displayed and highlighted.

-- Momentarily depress and release the STEP push button to begin.

-- Using the same button toggle through the zone numbers (1-15), until the zone number for your geographic location appears in the display. The zone number will set automatically.

NOTE:

The default for the compass variance from the factory is 8. During programming, the Zone value will wrap around from Zone 15 to Zone 1.

-- Momentarily depress and release the >>BACK<< push button (4) return to the main menu.

-- Confirm that the correct direction is now indicated by the compass.

-- Using the scroll button (5 and 6), select " Turn Off Menu " to exit.
