F 150 Super Crew 2WD V8-4.6L SOHC VIN 6 (2003)
Compass: Description and Operation
ELECTRONIC COMPASS
A compass and outside temperature display are contained in the overhead console.
The compass and temperature display can be turned off and on by pressing the MODE switch in the overhead console. The vehicle heading is displayed
as one of N, NE, E, SE, S, SW, W, and NW.
Compass Accuracy
Magnetic mounted devices like antennas and luggage racks should not be located on the front third of the vehicle roof. Placing these devices near the
compass will cause inaccurate directional readings. If these devices must be used, accuracy may be improved by recalibrating the compass while the
devices are installed on the vehicle.
Driving near power lines, or driving in the area of large iron or steel structures can temporarily change the compass' heading. If the compass remains
inaccurate after driving near such objects, demagnetize the vehicle, refer to Vehicle Demagnetizing and recalibrate the compass.
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 the adjacent zones and will become noticeable as the vehicle crosses multiple zones. A correct zone setting eliminates the error.
Refer to Compass Zone Adjustment.
Temperature, Outside Air
The thermometer sensor is attached to the radiator frame behind the grille. The temperature can be displayed in Celsius or Fahrenheit by pressing the
MODE switch.
If the outside temperature falls below 3.3°C (38°F), the display will alternate from "ICE" to the outside temperature at a two second rate for one
minute.
The outside air temperature reading can be affected by engine heat when the vehicle is idling or has been off for less than two hours. The compass
and thermometer will limit the increase of the displayed temperature to one degree per minute at very low speeds or immediately after the ignition is
turned on. After two minutes at a sustained speed of at least 53 km/h (33 mph), effects of engine heat are minimal and the compass will display the
current outside temperature reading. Temperature decreases are always updated immediately.
If the outside air temperature sensor is short or open circuited, then the display will show 60°C (140°F) or -40°C (-40°F) respectively in place of
temperature.
