FORD 1999 F-550 v.1 - Manual (Page 20)

Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows the approximate
amount of fuel in the fuel tank in whole numbers (liters or gallons). If
your tank is full or nearly full, the display will be “F”. If your tank is
empty or nearly empty, the display will be “E”. Instantaneous fuel
economy cannot be reset.
Outside air temperature
The outside temperature display is
contained in the overhead console.
The temperature display can be
turned off and on by pressing the
MODE control on the overhead
console. The temperature can be
displayed in Centigrade or
Fahrenheit by pressing the MODE
control.
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.
Compass
The compass display is contained in the overhead console. The vehicle
heading is displayed as one of N, NE, E, SE, S, SW, W and NW.
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 or on the vehicle may also affect compass
accuracy. Adjustments may need to be made to the zone and calibration
of the compass.
