Chrysler 2004 Concorde Owner's Manual page 95

After completing three 360° 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.
NOTE: To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass (see variance map).
To Put Into a Calibration Mode
Turn on the ignition and set the display to "Compass/
Temperature." Press and hold the RESET button to
change the display between VAR (compass variance) and
CAL (compass calibration) modes. When the CAL sym-
bol is displayed complete 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.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 95
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.
