Electrochromic Inside Rearview Mirror
with Compass, Temperature Display and
OnStar Controls (If Equipped)
When on, an electrochromic mirror automatically dims
to the proper level to minimize glare from lights behind
you after dark.
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.
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 below.
To adjust between Fahrenheit and Celsius do
the following:
1. Press and hold the on/off button for 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 of inactivity, the new unit will be
locked in and the compass/temperature display
will return.
