GM Service Manual Online
For 1990-2009 cars only

The vehicle may have an automatic dimming rearview mirror with a compass and temperature display.

Automatic Dimming Mirror Operation

Automatic dimming reduces the glare of lights from behind the vehicle. The dimming feature comes on and the indicator light illuminates each time the vehicle is started.

Temperature Display

Press TEMP to turn the temperature display on or off. To alternate the temperature reading between Fahrenheit and Celsius, press and hold TEMP until the display blinks F and C. Press and release TEMP to toggle between the Fahrenheit and Celsius readings. After approximately four seconds of inactivity, the display stops blinking and displays 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.

Passenger Airbag Indicator

The mirror may have a passenger airbag indicator display located on the mirror, 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 .

Cleaning the Mirror

Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with glass cleaner.
