NOTE: A good calibration requires a level surface and
an environment free from large metallic objects such as
buildings, bridges, underground cables, railroad tracks,
etc.
Manual Compass Calibration
If the compass appears erratic and the CAL indicator
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually, as follows:
1. Turn ON the ignition switch.
2. Push and release the UP or DOWN button until the
System Setup (Customer-Programmable Features)
menu is reached, then push and release the SELECT
button.
3. Push and releasethe DOWN button until “Calibrate
Compass” is displayed in the EVIC then push and
release the SELECT button.
4. Push and release the SELECT button to start the
calibration. The “CAL” indicator will be displayed in
the EVIC.
5. Complete one or more 360–degree turns (in an area
free from large metal or metallic objects) until the
“CAL” indicator turns off. The compass will now
function normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences, and provide the most accurate compass
heading. For the most accurate compass performance, the
compass must be set using the following steps.
