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. Use the COMPASS side of the button located at the
bottom of the mirror. Press and hold COMPASS
until a zone number appears in the display.
2. Find your current location and variance zone number
on the following zone map.
3. Press COMPASS on the bottom of the mirror until
the new zone number appears in the display. After
you stop pressing the button, the display will show a
“C” in the direction display within a few seconds.
(This is the automatic calibration mode -- you’ll
need to drive in a circle to calibrate the mirror. See
“Compass Calibration” listed previously.)
