Compass Calibration The compass may need calibration if one of the following occurs: Outside Power Heated Mirrors The controls for the outside power mirrors are located on the driver's door. • After approximately five seconds, the display does not show a compass heading (N for North, for example), there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder, or a similar magnetic item. • The compass does not display the correct heading and the compass zone variance is set correctly. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push the on/off button for approximately 12 seconds or until CAL is displayed. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. Move the top selector control to the left or right to select either the driver's or passenger's mirror. To adjust the direction of the mirror, use the arrows on the round four-way control. Adjust each outside mirror so that a little of the vehicle and the area behind it can be seen while sitting in a comfortable, driving position. Keep the control in the center position when not adjusting either outside mirror. Cleaning the Mirror When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing. 2-43
