Mirrors equipped with OnStar controls can be placed in calibration mode by pressing and holding the on off button until a "C" is shown in the compass display. Compass Variance 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.

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. To adjust for compass variance: 1. Find your current location and variance zone number on the following zone map. 2. Press and hold COMPASS (or the on/off button for mirrors equipped with OnStar controls) until a zone number appears in the display. 3. Once the zone number appears in the display, press the COMPASS (or the on/off button for mirrors equipped with OnStar controls) button quickly until the correct zone number appears in the display. Stop pressing the button and the mirror will return to normal operation. If "C" appears in the compass window, the compass may need calibration. See "Compass Calibration" explained previously. 2-51

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 reads a direction, or
drive the vehicle on your everyday routine.
Mirrors equipped with OnStar controls can be placed in
calibration mode by pressing and holding the on off
button until a “C” is shown in the compass display.
Compass Variance
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. 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.
To adjust for compass variance:
1.
Find your current location and variance zone number
on the following zone map.
2.
Press and hold COMPASS (or the on/off button for
mirrors equipped with OnStar controls) until a zone
number appears in the display.
3.
Once the zone number appears in the display, press
the COMPASS (or the on/off button for mirrors
equipped with OnStar controls) button quickly until
the correct zone number appears in the display.
Stop pressing the button and the mirror will
return to normal operation. If “C” appears in the
compass window, the compass may need calibration.
See “Compass Calibration” explained previously.
