Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. In order to ensure compass accuracy, the com-
pass variance should be properly set according to the
compass variance map zone that the vehicle is in.
NOTE: Magnetic materials should be kept away from
the top of the instrument panel. This is where the
compass sensor is located.
To Set the Variance
NOTE: Refer to the "Compass Variance Map" in the
following "Electronic
(EVIC)" section for your Zone Value.
Vehicle Information
Start the engine, and leave the transmission gear selector
lever in the PARK position. Press and hold (approxi-
mately ten seconds) the CMTC reset button until the
current variance zone number is displayed. To change the
zone, press and release the CMTC reset button to incre-
ment the variance one step. Repeat as necessary, until the
desired variance is achieved.
NOTE: The factory default Zone is 8. During program-
ming, the zone value will wrap around from Zone 15 to
Zone 1.
Manual Compass Calibration
If the compass appears erratic, inaccurate or abnormal,
you may wish to calibrate the compass. Prior to calibrat-
ing the compass make sure the proper zone is selected.
1. Start the engine, and leave the transmission in the
