Compass/Temperature Display
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To ensure compass accu-
racy, the compass variance should be properly set accord-
ing to the variance map for the zone where the vehicle
will be driven. When properly set, the compass will
automatically account for this difference.
NOTE: Magnetic and battery powered devices, (such as
cell phones, iPod’s, radar detectors, PDA’s and laptops)
should be kept away from the top of the instrument
panel. This is where the compass module is located and
such devices may interfere and cause false compass
readings.
To Set the Variance
Start the engine, and leave the transmission shift lever in
the PARK position. Press and hold (approximately ten
seconds) the compass/temperature RESET button until
the current variance zone number is displayed. To change
