Nitro 2WD V6-4.0L (2007)
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:
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. 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.
4. 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.
5. Confirm that the correct directions are now indicated by the compass.
