metallic objects) until the “CAL” message displayed in
the EVIC turns off. The compass will now function
normally.
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. Start the engine. Leave the shift lever in PARK in order
to enter the EVIC Programming Menus.
2. Push the MENU button until Personal Settings
(Customer-Programmable Features) displays in the
EVIC.
3. Push the DOWN button until “Calibrate Compass”
displays in the EVIC.
4. Push and release the SELECT button to start the
calibration. The “CAL” indicator will display 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 differ-
ences and provide the most accurate compass heading.
