2005 FORD F650 engine

Transmission temperature gauge
(automatic transmission only):
Indicates the temperature of the
transmission fluid. The normal
temperature range is 150°F (65°C)
to 230°F (110°C). Readings of 230°F
(110°C) to 250°F (121°C) are
satisfactory for intermittent
operation and are not cause for
alarm. Operation above 250°F
(121°C) can cause the fluid to break
down and will result in component damage.
Odometer:Registers the total miles
(kilometers) of the vehicle.
Trip odometer:Registers the miles
(kilometers) of individual journeys.
To reset, depress the control.
Hourmeter:Registers the hours the
engine has been operating.

Tachometer:Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Battery voltage gauge:Indicates
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:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (as indicated by the
arrows). If the needle falls below
the normal range, stop the vehicle,
turn off the engine and check the
engine oil level. Add oil if needed. If
the oil level is correct, have your
vehicle checked at your dealership
or by a qualified technician.
Air filter restriction gauge:
Measures the vacuum inside the air
cleaner. The more the air cleaner is
restricted (dirty, clogged), the
higher the vacuum reading. Change
the air filter when the gauge reads
25 inches. After installation of the
new filter element, reset the gauge
to 0.

Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the on position). If your vehicle
is equipped with dual fuel tanks, the
engine will draw fuel from the
passenger-side fuel tank only. With
dual fuel tanks, the vehicle will be
equipped with a fuel transfer pump system that will draw fuel from the
driver-side fuel tank and send fuel to the passenger-side fuel tank. The
passenger-side fuel tank must have fuel in it at all times otherwise the
vehicle may stall and may be difficult to re-start. The fuel gauge reads
the fuel level only from the passenger-side fuel tank.
Air pressure gauge (if equipped):
All vehicles equipped with air brakes
have a dual-pointer air gauge to
indicate the pressure in each brake
circuit. The green pointer indicates
the air pressure in the primary
system and the red pointer indicates
the air pressure in the secondary
system. When the pressure is too low
for normal brake operation (less than
60 psi [414 kPa]) and the ignition is
on:
•a warning buzzer will sound and
•a warning light will illuminate in the instrument cluster
Vehicles equipped with hydraulic brakes and an air compressor have a
single-pointer air gauge.
Note:This system doesnothave a low air pressure warning buzzer or a
low air pressure warning light.
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 or suspension system to
operate properly.

Fold-away mirrors
The mirrors can be manually folded forward or backwards for narrow
spaces like driving through an automatic car wash or backing out of a
garage with the trailer tow mirror.
The telescoping feature (if equipped) allows the mirror to extend
approximately three inches (76 mm). This feature is especially useful to
the driver when towing a trailer.
SPEED CONTROL (IF EQUIPPED)
To turn speed control on
Instrument panel-mounted
controls:Press CRUISE RPM. If the
vehicle is moving, speed control will
be enabled; if the vehicle is
stationary, engine RPM can be
controlled.
Steering wheel-mounted
controls:Press ON. Vehicle speed
cannot be controlled until the
vehicle is traveling at or above 30
mph (48 km/h).
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.

To turn speed control off
Instrument panel-mounted
controls:Press OFF or turn off the
ignition.
Once speed control is switched off,
the previously programmed engine
RPM will be erased.
Steering wheel-mounted
controls:Press OFF or turn off the
ignition.
Once speed control is switched off,
the previously programmed set
speed will be erased.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
To set a speed
Instrument panel-mounted
controls:Press SET +. If the
vehicle is moving, this will set the
vehicle speed. If the vehicle is
stationary, this will set the vehicle
idle RPM.
Steering wheel-mounted
controls:Press SET ACCEL. For
speed control to operate, the speed
control must be on and vehicle
speed must be at or above 30 mph
(48 km/h)

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 30 mph (48 km/h) or engine RPM falls
below 1,000 RPM, your speed control will disengage; this is normal.
Pressing RESUME - (instrument panel-mounted controls) or RES
(steering wheel-mounted controls) will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
To set a higher set speed
Instrument panel-mounted
controls:Press and hold SET +. If
the vehicle is moving, this will
increase vehicle speed; if the vehicle
is stationary, this will increase
engine RPM. Release the control
when the desired vehicle
speed/engine RPM is reached.
Press and release SET + to operate the tap-up function. Each press will
increase the set speed by 1 mph (1.6 km/h) or engine RPM in idle mode.
Steering wheel-mounted
controls:Press and hold SET
ACCEL. Release SET ACCEL when
the desired vehicle speed is
reached. SET ACCEL can also be
pressed and released to operate the
tap-up function which will increase
vehicle speed in increments of 1
mph (1.6 km/h).
You can accelerate with the accelerator pedal at any time during speed
control usage. Releasing the accelerator pedal will return your vehicle to
the previously programmed speed.
