Manual Compass Calibration
If the compass appears erratic, inaccurate or abnormal, you may wish to calibrate the compass. Prior to calibrating the compass, make sure the proper zone is selected.
1. Start the engine and leave the transmission in the PARK position.
2. Press and hold the RESET button (for approximately 10 seconds) until the current variance zone number is displayed.
3. Release the RESET button, then press and hold again for approximately 10 seconds, until the direction is displayed, with the CAL indicator on continuously in the display.
4. To complete the compass calibration, drive the vehicle in one or more complete 360–degree circles, under 5 mph (8 km/h) in an area free from power lines and large metallic objects, until the CAL indicator turns off. The compass will now function normally.
