Compass Variance

The mirror is set to zone eight upon leaving the

factory. It will be necessary to adjust the compass

to compensate for compass variance if the

vehicle is driven outside zone eight. Under certain

circumstances, such as a long distance,

cross-country trip, it will be necessary to adjust the

compass variance.

Compass variance is the difference between

earth’s magnetic north and true geographic north.

If the mirror is not adjusted to account for zone

changes, the compass could give false readings.

To adjust for zone changes, do the following:

1. Find your current location and variance zone

number on the zone map that follows.

2. Press and hold the “auto highbeam” button

approximately six seconds until a zone

number appears in the display.

3. Once the zone number appears in the display,

press the “auto highbeam” button quickly until

you reach the correct zone number. Stop

pressing the button and the mirror will return to

normal operation. If C appears in the compass

window, the compass needs calibration. See

“Compass Calibration” listed previously.
