FORD F-250 - Manual (Page 19)

Tachometer
Indicates the engine speed in
revolutions per minute.
Driving with your tachometer
pointer at the top of the scale or in
the red zone may damage the
engine.
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), 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.
