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. Press the MENU button until Personal Settings
(Customer-Programmable Features) displays in the EVIC.
3. Press the DOWN button until “Calibrate Compass”
displays in the EVIC.
4. Press and release the SELECT button to start the calibra-
tion. 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.
NOTE: Magnetic materials should be kept away from
the top of the instrument panel; this is where the compass
sensor is located.
