UNDERSTANDING THE FEATURES OF YOUR VEHICLE 113 Automatic Compass Calibration The automatic calibrating feature of the compass eliminates the need to calibrate the compass due to normal varying conditions. Compass Variance Selection Variance is the difference between magnetic North and geographic North. For proper compass function, the correct variance zone must be set. Refer to the variance map for the correct variance zone. To check the variance zone, the ignition switch must be on and the compass/ temperature displayed. Press and hold the STEP button for about 5 to 10 seconds until ZONE and the number appears in the display. The number displayed is the variance zone used by the compass. To change the zone, press the STEP button to scroll through numbers 1 through 15. When the correct variance is selected release the step button and the Compass/Temperature display will return to normal after approximately 15 seconds. 3
