Engine starting (with parking brake applied)
Safety and
emergency
equipmentBefore entering the cab, verify that the vehicle is
equipped with spare electrical fuses (if used),
three red reflective triangles, a properly charged
and rated fire extinguisher and wheel chocks.
Walk around the vehicle and verify all steps and
grab handles, inside and out (as well as behind),
are tight and clean. Use extreme caution and a
three-point stance at all times.
Inspect door latches for proper closing, latching
and locking.
Starting the
engineSet the parking brake. If starting a vehicle with a
manual transmission, press the clutch and verify
the transmission is in neutral. If starting a vehicle
with an automatic transmission, make sure the
gearshift lever is in positionNorP(if equipped
with a park position).
Diesel engine:Turn the key to the on position.
Turn the key to start when the wait to start
indicator light in the instrument cluster turns off.
Gasoline engine:Turn the key to start, and
then release it as soon as the engine starts.
Engine oil
pressureVerify pressure builds to normal operating range.
Low air pressure
warning tone (if
equipped with an
air compressor)A tone indicating low air pressure should sound
immediately after the engine starts but before the
compressor has built-up pressure. The tone
should stop when the air pressure reaches 70 psi
(483 kPa) (or more). Let the air pressure build
to governed cutout pressure, which should occur
between 115–130 psi (793–896 kPa).
AcceleratorPress the accelerator and verify that it operates
smoothly, without any binding or irregular feel.
Release the pedal and verify the engine returns
to idle speed immediately.
VoltmeterCheck the gauge (diesel engine) or indicator light
(gasoline engine) to verify the alternator is
charging.

Parking brakeVerify the parking brake holds the vehicle by
gently trying to pull forward with the parking
brake applied.
Air brakesVerify operation using the following procedure.
Chock the wheels, if necessary. Push in the
parking brake and, on tractors, push in the
tractor parking brake knob:
1. Verify the air compressor or governor cutout
pressure is approximately 120 psi (827 kPa).
2. Turn off the engine, and then turn the key
back to the on position (without starting the
engine).
3. Without the brake pedal applied, note the air
pressure drop for one minute. It should be less
than 2 psi (14 kPa) for single vehicles and 3 psi
(21 kPa) for combination vehicles.
4. Press and hold the brake pedal with 90 psi
(621 kPa) or more. Make sure there is no more
than a 3–psi (21 kPa) per minute leak for single
vehicles and a 4–psi (28 kPa) per minute leak for
combination vehicles.
5. Pump the brake pedal to deplete the system of
air pressure. The warning light and tone should
turn on at 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.

Gauge Package (If Equipped)
Your vehicle may be equipped with an optional gauge package that has
one of the following configurations:
1.Transmission temperature
gauge:Displays the
transmission temperature at the
transmission sump.
2.Hourmeter:Displays the hours

WARNING LAMPS AND INDICATORS
The following warning lamps and indicators alert you to a vehicle
condition that may become serious. Some lamps illuminate when you
start your vehicle to make sure they work. If any lamps remain on after
starting your vehicle, see the respective system warning lamp for further
information.
Note:Some warning indicators appear in the information display. These
indicators function the same as a warning lamp but do not display when
you start your vehicle.
Anti-Lock Braking System
If it illuminates when you are driving, this indicates a
malfunction. You continue to have the normal braking system
(without ABS) unless the brake warning lamp is also
illuminated. Have the system checked by an authorized dealer.
Brake System
To confirm the brake system warning light is functional, it
momentarily illuminates when you turn the ignition to the on
position when the engine is not running, or in a position
between on and start.
If the brake system warning light does not illuminate at this time, seek
service immediately from an authorized dealer.

WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It takes you longer to stop the vehicle. Have
the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Charging System
It illuminates when the 12–volt battery is not charging properly.
Contact an authorized dealer as soon as possible. This indicates
a problem with the electrical system or a related component.
Check Fuel Cap (gasoline engine only)
It illuminates when you may not have installed the fuel cap
properly. Continued driving with this light on may cause the
service engine soon warning indicator to come on.
Check Suspension
It illuminates when you press the air suspension dump switch.
Check Transmission (Allison automatic transmission only)
It illuminates while driving if a transmission problem exists;
shifting may be restricted. Depending on the severity of the
problem, the shifter’s digital read-out may turn blank.
On MD 3000 series transmissions, operation may continue in order to
reach service assistance. The control unit may not respond to shift
selector requests, since there are operating limitations on the
transmission (such as upshift and downshift restrictions). Direction
changes do not occur.
Cruise Control
It illuminates when you switch this feature on.

•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Fuel Filler Cap
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
WARNING:If you do not use the proper fuel filler cap, excessive
pressure or vacuum in the fuel tank may damage the fuel system
or cause the fuel cap to disengage in a crash, which may result in
possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap designed for your vehicle. The customer warranty may be void for
any damage to the fuel tank or fuel system if the correct genuine Ford,
Motorcraft or other certified fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a quarter–turn on
and off feature. When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise a
14–turn until it clicks at least once.
If the check fuel cap light appears in the instrument cluster and stays on
after you start the engine, you not have installed the fuel filler cap
properly.
If the fuel cap light remains on, at the next opportunity, safely pull off
the road, remove the fuel filler cap, align the cap properly and reinstall
it. The check fuel cap light may not reset immediately; it may take
several driving cycles for the indicators to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by normal city and highway driving.
