Compass Calibration
WARNING: This page is about a different car, the 2002 Lincoln Navigator and 2002 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Turn off all unnecessary electrical accessories. Drive to a level, open area which is free from power lines, large metallic objects and structures. Press and hold the button located on the upper left side of the compass sensor module for 2-4 seconds or until CAL is displayed. Release switch and drive vehicle in circles until CAL disappears from compass display.
