To adjust for compass variance, do the following: 3. If a new zone value is desired, briefly press the on/off button until you reach your desired zone number. 4. After four seconds, the zone entry mode will end. The display will return to normal operation and the new zone number will be set. 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. Automatic Dimming Rearview Mirror with Compass Your vehicle may have an automatic-dimming rearview mirror with a compass. 1. Find your current location and determine the correct zone number from the zone map. 2. Press and hold the on/off button for approximately six seconds until ZONE appears in the display. Then release the button. The number displayed is the current zone value. 2-43
