Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE: Keep magnetic materials away from the top of
the instrument panel, such as IPODs, Cell Phones, Lap-
tops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
To Set the Variance
Start the engine and leave the transmission gear selector
lever in the PARK position. Press and hold the CMTC
reset button (for approximately ten seconds) until the
current variance zone number is displayed. To change the
zone, press and release the CMTC reset button to increase
the variance one step. Repeat as necessary until the
desired variance is achieved.
