Compass Variation Adjustment

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

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 setting may need to be changed.

To set the compass variance:

Turn the ignition switch to the On position.
Press and release the C/T button (1) so that the EVIC display is in the Compass/Temperature mode.
Depress and hold the C/T push button (1) for approximately five to ten seconds. The last variance zone number will appear in the EVIC display.
Press and release the STEP button (3) until the zone number for your geographic location appears in the display.
Depress and release the RESET push button (2) to exit.
Confirm that the correct directions are now indicated by the compass.
