FORD 2001 F-550 v.1 - Manual (Page 18)

Battery voltage gauge
This shows the battery voltage when
the ignition is in the ON position. If
the pointer moves and stays outside
the normal operating range (as
indicated by arrows), have the
vehicle’s electrical system checked
as soon as possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the “L” and “H”).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer to Engine
oil in the Maintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.
TRIP COMPUTER (IF EQUIPPED)
The trip computer tells you about the condition of your vehicle through
a constant monitor of vehicle systems. You may select display features on
the trip computer for a display of status.
The appearance of your vehicle’s trip computer may differ depending on
your vehicle’s option package, but the functions are the same.
The trip computer only operates with the ignition in the ON position.
