FORD 2008 Explorer Sport Trac v.1 - Manual (Page 131)

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/calibration adjustment.
Note: Compass zone and calibration adjustments can be entered by
using the INFO and SETUP MENU controls or using the reset button on
top of the compass sensor mounted behind the mirror.
Compass zone adjustment (if equipped)
1. Determine your magnetic zone by

message center display changes to
show the current zone setting (XX).

repeatedly until the correct zone
setting for your geographic location
is displayed on the message center.
