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

See Compass for more information about the compass display. See "Temperature Display" after, in this section.

Vehicles with OnStar® have three additional control buttons located at the bottom of the mirror. See your dealer/retailer for more information on the system and how to subscribe to OnStar®. See OnStar® System for more information on the services OnStar® provides.

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

Press or depending on the mirror, press TEMP to turn the temperature display on or off.

To adjust between Fahrenheit and Celsius:

1. Press and hold or depending on the mirror, press TEMP until either a flashing F or C appears.
2. Press or TEMP again to change the display to the desired unit of measurement. After approximately four seconds of inactivity, the new unit locks in and the display returns.

If an abnormal temperature reading is displayed for an extended period of time, consult your dealer/retailer. Under certain circumstances, a delay in updating the temperature is normal.

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 displays the word ON, or an airbag symbol in Canada, when the passenger airbag is enabled. For more information, see Passenger Sensing System for more information.

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