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-

NOTE: Magnetic materials should be kept away from
the top of the right rear quarter window. This is where
the compass sensor is located.
1. Turn the ignition switch ON.
