Automatic Dimming Rearview Mirror with OnStar®, Compass and Temperature Display Your vehicle may have this feature. When on, an automatic dimming mirror automatically dims to the proper level to minimize glare from lights behind you after dark. Temperature and Compass Display Press the on/off button, located to the far left, briefly to turn the comp/temp display on or off. If the display reads CAL, you will need to calibrate the compass. For more information on calibration, see "Compass Calibration" later in this section. To set the readings to appear in either Fahrenheit or Celsius do the following: 1. Press and hold the on/off button for approximately four seconds until either a flashing °F, or °C appears. 2. Press the button again to change the display to the desired unit of measurement. After approximately four seconds the unit of measurement will be set and the compass/temperature display will return. The mirror also includes a duel 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.
