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. Compass Operation Press the on/off button once to turn the compass on or off. When the ignition and the compass feature are on, the compass will show two character boxes for about two seconds. After two seconds, the mirror will display the compass heading. Automatic Dimming Rearview Mirror with Compass Your vehicle may have an automatic dimming rearview mirror with a compass display. The mirror includes an eight-point compass display in the upper right corner of the mirror face. When on, the compass automatically calibrates as the vehicle is driven. Compass Calibration If after two seconds, the display does not show a compass heading (for example, N for North), 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. If the letter C should ever appear in the compass window, the compass may need calibration. The mirror can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. The compass can be placed in calibration mode manually by pressing and holding the on/off button until a C is shown in the compass display. Mirror Operation O(On/Off): Press and hold the button, located on the lower left side of the mirror face, for about three seconds to turn the automatic dimming feature on or off. The indicator light will illuminate when this feature is active. The automatic dimming feature is active each time the vehicle is started. 2-39
