FORD 2009 Expedition v.2 - Manual (Page 132)

Outside air temperature (OAT)
The outside air temperature is
shown together with the compass
heading in the bottom row of the
message center display.
Compass display (if equipped)
The compass heading is displayed as one of N, NE, E, SE, S, SW, W and
NW in the message center display.
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in, on or near the vehicle may also affect
compass accuracy.
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 zone adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is up
to 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 calibration adjustment.
Compass zone adjustment (if equipped)
1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.
2. Press and hold the RESET stem
to scroll through the information
displays until the message center
displays HOLD RESET FOR
SETUP MENU.
3. Press and hold the RESET stem
for approximately two seconds until
the message center displays HOLD RESET FOR SYSTEM CHECK.
4. Press and release the RESET stem to scroll through the system check
displays until the message center displays COMPASS ZONE <XX>.
