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 the ignition ON 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 one 360 degree turn 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.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
