Compass Operation This is the on/off button, located on the lower left side of the mirror for the electrochromic and compass functions of the rearview mirror. The mirror also 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. 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. Mirror Operation To turn on the automatic dimming feature, press and hold the on/off button for about three seconds. To turn off automatic dimming, press and hold the on/off button for about three seconds again. The green indicator light will be illuminated when this feature is active. The automatic dimming feature will be active each time the vehicle is started. 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 approximately two seconds. After two seconds, the mirror will display the compass heading. Compass Calibration If after two 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. 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 by pressing and holding the on/off button until a "C" is shown in the compass display. 2-58
