2002 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.

GAUGES
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 ªHº and ªCº). 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 ªLº and ªHº);
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.
Air pressure gauge and warning buzzer (if equipped)
Indicates the amount of air pressure
in the brake system (green=primary,
red=secondary) in pounds per
square inch. When the pressure is
too low for normal brake operation
(less than 414 kPa [60 psi]) and the
ignition is turned to ON:
²a warning buzzer sounds
²the warning light illuminates
All vehicles have a dual-pointer air
pressure gauge to indicate the pressure in both brake circuits.
Do not drive the vehicle when the low air pressure buzzer is
sounding or the warning light is lit. These warnings indicate
there is not enough air pressure for the brake system to operate
properly.

SPEED CONTROL (IF EQUIPPED)
To turn speed control on
7.3L Power Stroke engine
²Press ON.
Vehicle speed cannot be controlled
until the vehicle is traveling at or
above 48 km/h (30 mph).
Do not shift the gearshift lever
into N (Neutral) with the speed
control on.
Do not use the speed
control in heavy traffic or
on roads that are winding,
slippery, or unpaved.

Press CRUISE RPM. If the vehicle is
moving, speed control will be
enabled; if the vehicle is stationary,
engine RPM can be controlled.

To set a speed
7.3L Power Stroke engine
²Press 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.
Caterpillar/Cummins engines
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.
