Dodge 2013 Challenger - Manual (Page 243)

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 release the MENU button until Personal
Settings displays in the EVIC.
3. Press the UP or DOWN button until “CALIBRATE
COMPASS” displays in the EVIC.
4. Press and release the SELECT button to start the calibra-
tion. The message “CAL” will display in the EVIC.
5. Slowly 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 differ-
ences and provide the most accurate compass heading.
