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 the vehicle is
outside of 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, the
compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the on/off button until a Z and a
zone number appears in the display. The compass
is now in zone mode.
3. Keep pressing the on/off button until the desired
zone number appears in the display. Release
the button. After approximately four seconds of
inactivity, the new zone number will be locked
in and the compass/temperature display will return.
4. Calibrate the compass as described next.
