Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to set the compass manually. When the vehicle is
new, the compass may appear erratic and the EVIC will
display “CAL” until the compass is calibrated. You may
also calibrate the compass by completing one or more 360
degree turns (in an area free from large metal or metallic
objects) until the “CAL” message displayed in the EVIC
turns off. The compass will now function normally.
Manual Compass Calibration
If the compass appears erratic and the “CAL” message
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:
1. Turn the ignition switch ON.
2. Press and hold the HOME button for approximately
two seconds.
3. Press the SCROLL button until “Calibrate Compass”
displays in the EVIC.
4. Press and release the FUNCTION SELECT button to
start the calibration. The message “CAL” 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”
message 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 head-
ing.
