corner of the mirror that shows the compass reading and
the outside temperature.
There are three additional buttons for the OnStar
system. See your dealer for more information on the
system and how to subscribe to OnStar

Temperature and Compass Display
Press the on/off button, located in the center, to cycle
between °F, °C and off. If the display reads CAL,
the compass needs to be calibrated. For more
information, see "Compass Calibration" later in this
section.
If an abnormal temperature reading is displayed for an
extended period of time, please consult your dealer.
Under certain circumstances, a delay in updating
the temperature is normal.

Compass Variance

magnetic north and true geographic north. If not
adjusted to account for compass variance, the mirror's
compass could give false readings. The mirror is
set in 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, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance.
