Compass
Compass Operation
There is a compass display in the upper right corner of
the mirror.
Press O to turn the compass display on or off.
When the ignition and the compass feature are on, the
compass displays the current compass direction,
after a few seconds.
Compass Calibration
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km) or less until the display reads
a direction.
If after a few 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, note pad holder, or similar object. If the letter C
appears in the compass window, the compass may
need to be reset or calibrated.
Compass Variance
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 your current location and variance zone
number on the following zone map.
2. Press and hold O until the zone number displays.
The number shown is the current zone number.
3. Scroll through the zone numbers that appear in the
window on the mirror by pressing the O button.
Once you find your zone number, release the
button. After about four seconds, the mirror returns
3-33
