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 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 zone number

appears in the display.

3. Once the zone number appears in the display, 

press the on/off 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” listed previously.
