Passenger Airbag Indicator The vehicle may be equipped with a passenger airbag indicator, on the mirror glass, just above the buttons. If the vehicle has this feature, the mirror will display the word ON, or an airbag symbol in Canada, when the passenger airbag is enabled. For more information, see Passenger Sensing System on page 1-61. Automatic Dimming Mirror Operation The automatic dimming mirror function is turned on automatically each time the ignition is started. To operate the automatic dimming mirror, do the following: 1. Make sure the green indicator light, located to the left of the on/off button, is lit. If it's not, press and hold the on/off button until the green light comes on, indicating that the mirror is in automatic dimming mode. 2. Turn off the automatic dimming mirror function by pressing and holding the on/off button until the green indicator light turns off. 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. Temperature Display Automatic Dimming Rearview Mirror with Compass and Temperature Display If the vehicle is equipped with an automatic mirror, it will, when on, automatically dim to the proper level to minimize glare from lights behind you after dark. The mirror also includes a display in the upper right corner of the mirror face. The compass reading and the outside temperature will both appear in the display at the same time. The dual display can be turned on or off by briefly pressing either the TEMP or the COMP button. 2-44 The temperature can be displayed by pressing the TEMP button. Pressing the TEMP button once briefly, will toggle the temperature reading on and off. To alternate the temperature reading between Fahrenheit and Celsius, press and hold the TEMP button until the display blinks F and C. Press and release the TEMP button to toggle between the Fahrenheit and Celsius readings. After approximately four seconds of inactivity, the display will stop blinking and display the last selection made. If an abnormal reading is displayed, for an extended period of time, please consult your dealer. Under certain circumstances, a delay in updating the temperature is normal.
