Compass Zone Adjustment - Ford 2002 Explorer Owner's Manual

Instrumentation
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer to Compass calibration
adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer to Compass zone adjustment.

Compass zone adjustment

you are in for your geographic

4. Insert a paperclip into the small
hole on the bottom of the compass
sensor or press the button on the

5. Release pressure on the paperclip or button and then slowly press it
down again.
6. Continue to press until ZONE
appears in the instrument cluster
display, then release. The display
should show the current zone
