the anti-lock brake system is disabled and normal braking is still effective
unless the brake warning light also remains illuminated.
Wait to start
Indicates the air intake heater is in
operation and special starting
procedures are required. Refer to
theStartingchapter.
If equipped with an air
intake heater, DO NOT use
ether or any other starting fluids.
The use of starting fluids (ether)
in an engine equipped with an air
intake heater could result in
damage and/or personal injury.
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
water in fuel 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 Care
section 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.

These and other temporary malfunctions can be corrected by filling the
fuel tank with good quality fuel. After three driving cycles without these
or any other temporary malfunctions present, theService Engine Soon
light should turn off. (A driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No additional vehicle service is
required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the fuel system, interior floor coverings or other
vehicle components, possibly causing a fire.
Key-in-ignition warning chime
Sounds when the ignition key is left in the ignition in the OFF/LOCK or
ACC position and the driver’s door is opened.
Headlamps on warning chime
Sounds when the headlamps or parking lamps are on, the ignition is off
(and the key is not in the ignition) and the driver’s door is opened.
Safety belt warning chime
Sounds to remind you to fasten your safety belts.
For information on the safety belt warning chime, refer to theSeating
and safety restraintschapter.

GAUGES
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion. The ignition
should be in the OFF position while
the vehicle is being refueled. When
the gauge first indicates empty,
there is a small amount of reserve
fuel in the tank. When refueling the
vehicle from an empty indication, the amount of fuel that can be added
will be less than the advertised capacity due to the reserve fuel.
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
carechapter.

POSITIONS OF THE IGNITION
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks the steering wheel,
automatic transmission gearshift
lever and allows key removal.
3. OFF, shuts off the engine and all
accessories without locking the
steering wheel.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.

Reverse is obtained by putting the
gearshift lever in R (Reverse) and
engaging the clutch while pressing
lightly on the accelerator.

Power-take off operation (PTO) with a manual transmission
Transmission-mounted power take-off units are available for local
installation on Ford vehicles. See your Body Builder’s Layout Book for
restrictions on use and installation of power take-off units.
To engage the PTO unit, stop the vehicle and place the transmission
control in neutral. Depress the clutch and allow the gears to stop
rotating, then engage the PTO unit. The PTO can also be selected with
the transmission in gear as long as the clutch is depressed.

When operating the PTO unit with the vehicle stationary, first set the
parking brake (chock the wheels if the vehicle is on a hill or other
unlevel surface).
DRIVING WITH AN AUTOMATIC TRANSMISSION, IF EQUIPPED
Allison automatic transmission
Do not allow your vehicle to coast in N (Neutral). Transmission
braking is not available in N (Neutral). Allowing the vehicle to
coast in N (Neutral) could result in loss of vehicle control and severe
transmission damage.
The Allison automatic transmissions are a torque converter type, full
power shifting and fully automatic. They also have the added flexibility
of manually selecting and holding in the lower drive ranges which permit
the drive selection of the most suitable gear range to match varying road
and load conditions. To prevent destructive overspeeding of the engine,
the hold feature is not infinite, resulting in upshifts from the hold range
to the next higher range at some speed above the no-load governed
speed of the engine.
Allison AT-545
These transmissions have no P (Park) position. Before leaving
the driver’s seat, always shift into N (Neutral) and set the
parking brake. Shut off the engine and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
This transmission provides four forward speeds and one reverse range.
R (Reverse)
Use this position to back the vehicle. Completely stop the vehicle before
shifting from R (Reverse) to any forward gear (1, 2, 3 or D). The reverse
warning signal will sound when the selector is in R (Reverse). Reverse
has only one gear and provides the greatest gear reduction.
Driving
102
Page 103 of 208

N (Neutral)
Place the selector in N (Neutral) before starting the engine. Shift to N
(Neutral) and set the parking brake any time the engine is to be running
while the operator is not at the controls. The engine should be at idle
speed when any shift from N (Neutral) to a drive range is made.
D (Drive-Normal driving position)
The transmission starts in first gear and automatically shifts through
second, third and fourth depending on load and speed demands. This
range is used for highway driving under normal conditions.
3 and 2 (Third and Second)
Use these ranges when road, load or traffic conditions require a lower
gear. These ranges provide greater engine braking than D (Drive). When
conditions are improved that no longer require these lower gears, shift
back to D (Drive).
1 (First)
The transmission has to be manually shifted into 1 (First) and will not
shift into a higher gear. This range is used for extra heavy loads or where
maximum reduction is required.
Allison MD Series transmissions
These transmissions have no P (Park) position. Before leaving
the driver’s seat, always shift into N (Neutral) and set the
parking brake. Shut off the engine and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
These transmissions are electronically controlled and have a push button
shifter. MD transmissions are available in five- or six-speed driving
ranges.

Gearshift positions
R (Reverse)- Use this position to
back the vehicle. Completely stop
the vehicle before shifting from R
(Reverse) to any forward gear. The
reverse warning signal will sound
when the selector is in R (Reverse).
Reverse has only one gear and
provides the greatest traction. The
Select and Monitor indicators will
display R when reverse is attained.
N (Neutral)- Use N (Neutral) for
starting the engine. If the engine
starts in any gear other than N
(Neutral), the start circuit should be
serviced immediately. Shift to N
(Neutral) and set the parking brake
any time the engine is to be running
while the operator is not at the
controls. The engine should be at
idle speed when any shift from N
(Neutral) to a drive range is made.
The Select and Monitor indicators
will display N.
Do not allow your vehicle to coast in N (Neutral). Transmission
braking is not available in N (Neutral). This practice can also
result in transmission damage.
