80 UNDERSTANDING THE FEATURES OF YOUR VEHICLE Manual Compass Calibration If the compass appears erratic and the CAL light does not appear, you must calibrate the compass. Find an open area away from large metal objects. With the ignition ON and the compass/temperature displayed, press and hold the RESET button until the CAL symbol appears (about 10 seconds). Drive slowly, about 5 mph (8 km/h), in 3 complete 360° circles. The CAL light will turn off and the compass will be calibrated. 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 must be on and the compass/ temperature displayed. Press and hold the RESET button for about 5 seconds until VAR 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. Press the RESET button after selecting the proper zone to return to the normal compass/temperature display.
