2003 FORD F750 engine

Water in fuel (if equipped)
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to
remove water from the fuel. The indicator light illuminates when the fuel
filter/water separator has a significant quantity of water, or when the
ignition key is switched to the START position. If the light illuminates
when the engine is running, stop the vehicle as soon as safely possible,
shut off the engine and drain the filter bowl. Allowing water to stay in
the system could result in extensive damage to, or failure of, the fuel
injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure). Rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Air clean warning (if equipped)
Illuminates when the air system is
restricted (dirty, clogged).
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theLightschapter.
High beams
Illuminates when the high beam
headlamps are turned on.

Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the“H”and“C”). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.
Engine oil pressure gauge
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the“L”and“H”);
if the needle goes below the normal
range, 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 oilin theMaintenance
and specificationschapter). If the oil level is correct, have your vehicle
checked at your dealership or by a qualified technician.

To set a speed
7.3L Power Stroke engine
•Press SET ACCEL. For speed
control to operate, the speed
control must be ON and the
vehicle speed must be greater
than 48 km/h (30 mph).
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.

Press SET +. If the vehicles is
moving, this will set the vehicle
speed. If the vehicle is stationary,
this will set the vehicle idle RPM.
If you drive up or down a steep hill, your vehicle speed may vary
momentarily slower or faster than the set speed. This is normal.
Speed control cannot reduce the vehicle speed if it increases above the
set speed on a downhill. If your vehicle speed is faster than the set
speed while driving on a downhill, you may want to shift to the next
lower gear or apply the brakes to reduce your vehicle speed.
If the vehicle speed falls below 48 km/h (30 mph) or engine RPM falls
below 1 000 RPM, your speed control will disengage. This is normal.
Pressing RESUME - will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
