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:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold
Y for 12 seconds until a zone
number appears in the display. The compass is
now in zone mode.
3. Keep pressing the
Y 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.
