Compass Zone/Calibration Adjustment - Ford 2005 F250 Owner's Manual

Driver Controls
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.

Compass zone/calibration adjustment

1. Determine your magnetic zone by
referring to the zone map.
2. Turn ignition to the ON position.
3. Start the engine.
4. From Info menu, press and hold
the SETUP and RESET controls
simultaneously until the message
center display changes to show the
current zone setting (XX).
5. Press the SETUP control
repeatedly until the correct zone
setting for your geographic location
is displayed on the message center.
The range of zone values are from
01 to 15 and "wraps" back to 01.
6. To exit the zone setting mode,
and to "lock in" your change, press
and release the RESET control.
Perform compass calibration in an open area free from steel structures
and high voltage lines. For optimum calibration, turn off all electrical
accessories (heater/air conditioning, wipers, etc.) and make sure all
vehicle doors are shut.
