Page: 115 / 462

The compass can be placed in calibration mode
manually by pressing and holding
O or AUTO 3 ,
depending on the vehicle, until a C is shown in
the compass display.
The compass can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
The compass is set to zone eight. If you do not
live in zone eight or drive out of the area, the
compass variance needs to be changed to the
appropriate zone.
To adjust for compass variance:
1. Find the current location and variance
zone number on the following zone map.
2. Press and hold O or AUTO 3 until a zone
number displays.
3. Once the zone number displays, press O or
AUTO 3 repeatedly until the correct zone number
displays. 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.
