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:
•
A good calibration requires a level surface and an
environment free from large metallic objects such as
buildings, bridges, underground cables, railroad
tracks, etc.
•
Magnetic materials should be kept away from the top
of the right rear quarter window. This is where the
compass sensor is located.
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
