Jeep 2004 Liberty - Manual (Page 123)

After completing three 360 degree turns in an area free
from large metal or metallic objects, the CAL symbol will
turn off and the compass will function normally.
Manual Compass Calibration
If the compass appears erratic and the CAL symbol does
not appear, you must manually put the compass into the
“Calibration” mode.
To Put Into a Calibration Mode
Turn on the ignition and set the display to “Compass/
Temperature.” Press and hold the RESET button (more
than 10 seconds) to change the display between VARI-
ANCE (compass variance) and CAL (compass calibra-
tion) modes. When the CAL symbol is displayed com-
plete three 360 degree turns in an area free from large
metal objects or power lines. The CAL symbol will turn
off and the compass will function normally.
Compass Variance is the difference between magnetic
north and geographic north. In some areas of the country,
the difference between magnetic and geographic north is
great enough to cause the compass to give false readings.
If this occurs, the compass variance must be set according
to the Compass Variance Map.
