Electrochromic Mirror Operation The right side of the button, labeled TEMP, located at the bottom of the mirror, turns the electrochromic mirror on and off. An indicator light, located to the right of the TEMP button, will come on when the electrochromic mirror is turned on. To turn the mirror on, press and hold the TEMP button for six seconds. To turn the mirror off, press and hold the TEMP button for six seconds. The indicator light will turn off, and remain off until it is turned on, or until the vehicle is restarted. Compass Operation With the ignition on, the compass will show two character boxes. The mirror will display the compass heading. 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. Temperature Display Pressing the TEMP button once briefly will toggle the compass/temperature reading on and off. To alternate the temperature reading between Fahrenheit and Celsius, press and hold the TEMP button for three seconds until the display blinks _F and_C. Press and release the TEMP button to toggle between the Fahrenheit and Celsius readings. After five seconds of inactivity, the display will stop flashing and stay at the last setting. If an abnormal reading is displayed, please consult your dealer. 2-52
