Automatic Dimming Feature
The automatic dimming feature is turned on or off by
briefly pressing the COMP button located on the bottom
of the mirror face. A light on the mirror will be lit when
the feature is turned on. It will go out when the feature is
turned off.
Temperature Display
The TEMP button located on the bottom of the mirror
face changes the temperature display. You can select
F,
C, or turn the display off.
Compass Operation
Press the COMP button once briefly to turn the compass
on or off. When on, the display will show the compass
direction, with a maximum of two characters. For
example, “NE” is displayed for north
-
east.
Compass Calibration
Press and hold the COMP button down for six seconds
to activate the compass calibration mode. If your vehicle
has the optional mirror with the compass, temperature
display and OnStar system, press the on/off button for
nine seconds. “CAL” will be displayed in the
compass/temperature window on the mirror.
The mirror can be calibrated in one of two ways:
Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display shows “CAL”, or
drive the vehicle on your everyday routine.
(This method may take longer to calibrate).
Compass Variance
The mirror is set to zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, such as during a long
distance cross
-
country trip, it will be necessary to adjust
for compass variance. Compass variance is the
difference between earth’s magnetic north and true
geographic north. If not adjusted to account for compass
variance, your compass could give false readings.
