When the ignition and the compass feature are on, a character box displays for about two seconds. After two seconds, the mirror displays the direction the vehicle is facing.

When on, the compass automatically calibrates as the vehicle is driven. If, after two seconds, the display does not show a compass direction, (N for North, for example), there may be a strong magnetic field interfering with the compass. Interference can be caused by a magnetic antenna mount, magnetic note pad holder, or a similar magnetic item. If CAL should ever display in the compass window, the compass might need calibration.

Press and hold for several seconds to activate the compass calibration mode. CAL displays in the compass window on the mirror.

The mirror can be calibrated by driving the vehicle in circles at 5 mph (8 km) or less until the display shows a direction.

The mirror 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 until zone displays.
3. Once zone displays, press repeatedly until the correct zone number displays. If CAL displays in the compass window, the compass might need calibration. See "Compass Calibration" explained previously.
