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. Automatic Dimming Mirror Operation The automatic dimming mirror function is turned on each time the ignition is started. A light near the on/off button will come on to indicate the automatic dimming is on. If the automatic dimming function is off, press and hold the on/off button for four seconds to manually turn the system back on. Automatic Dimming Rearview Mirror with Compass and Temperature Display If the vehicle has this feature, the automatic dimming mirror automatically dims to the proper level to minimize glare at night from lights behind your vehicle. The mirror also has a dual display in the upper right corner of the mirror that shows the compass reading and the outside temperature. Temperature and Compass Display Press the on/off button, located in the center, to cycle between °F, °C and off. If the display reads CAL, the compass needs to be calibrated. For more information, see "Compass Calibration" later in this section. If an abnormal temperature reading is displayed for an extended period of time, please consult your dealer. Under certain circumstances, a delay in updating the temperature is normal. Y On/Off: Press this button to operate the automatic dimming and compass features. 2-34
