Manual Compass Calibration
If the compass appears erratic and the CAL light does not
appear, you must calibrate the compass. Find an open
area away from large metal objects. With the ignition ON
and the compass/temperature displayed, press and hold
the RESET button until the CAL symbol appears (about
10 seconds). Drive slowly, about 5 mph (8 km/h), in 3
complete 360° circles. The CAL light will turn off and the
compass will be calibrated.
Variance is the difference between magnetic North and
geographic North. For proper compass function, the
correct variance zone must be set. Refer to the variance
map for the correct variance zone. To check the variance
zone, the ignition must be on and the compass/
temperature displayed. Press and hold the RESET button
for about 5 seconds until VAR appears in the display. The
number displayed is the variance zone used by the
compass. To change the zone, press the STEP button to
scroll through numbers 1 through 15. Press the RESET
button after selecting the proper zone to return to the
normal compass/temperature display.
