Remember to turn the ignition off when refueling to allow this feature to
correctly detect the added fuel.
The low fuel indicator will display when the fuel level is at approximately
1/16 of the tank.
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 500 miles (800 km). This value is not
the same as the average fuel economy display. The running average fuel
economy is re-initialized to a factory default value if the battery is
disconnected.
XX.X MPG (L/100km)
Average fuel economy displays your average fuel economy in miles/gallon
or liters/100 km.
If you calculate your average fuel economy by dividing distance traveled
by gallons of fuel used (liters of fuel used by 100 kilometers traveled),
your figure may be different than displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET button (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
TIMER
Timer displays the trip elapsed drive time.
To operate, do the following:
1. Press and release RESET in order to start the timer.
2. Press and release RESET to pause the timer.
3. Press and hold RESET until the timer resets.

electrical accessories such as the
radio to operate while the engine is
not running.
2. LOCK – locks the automatic
transmission gearshift lever if
equipped with a P (Park) position
and allows key removal.
3. OFF – shuts off the engine and all
accessories.
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.
Starting the engine
WARNING:Operation of a diesel engine near flammable vapors
in the air may cause the engine speed to increase uncontrollably
and over speed. If this situation occurs, mechanical damage, fire,
explosion, personal injury or death could result.Turning off the
ignition key will not slow or stop the engine due to uncontrollable
fueling of the engine through flammable vapors being drawn into
the engine air inlet.Operation of components such as starter,
alternator, electric motors, etc. and static electricity could also ignite
flammable vapors.
Do not operate the truck in the possible presence of flammable vapors
unless both a complete hazard analysis is performed and necessary
additional safety processes and/or equipment such as vapor testing, air
intake shutoff devices, ventilation, etc. are utilized. The operator is
responsible for using those processes and/or equipment to ensure that
the diesel engine and all other components on the truck can be
operated safely under the specific conditions and hazards that may be
encountered.
Note:If equipped with Eaton UltraShift transmission, allow UltraShift to
power up before starting the engine. Engine cranking is delayed until the
transmission power up is complete and the gear display shows a solid N.

Note:When starting the engine, do not press the accelerator as engine
damage may result.
1. Ensure headlamps and all accessories are turned off, the parking
brake is applied and the transmission is in the neutral position (or P
[Park] for Allison 2200 transmissions).
2. Turn the key to the on position, but do not start the engine.
In cooler weather, the air intake
heater may activate the WAIT TO
START light in the instrument
cluster. If the WAIT TO START light
illuminates,do notcrank the engine until the light goes off.
WARNING: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 cause an
explosion and result in property damage and/or personal injury.
3. When the WAIT TO START light turns off, turn the key to the start
position; when the engine starts, release the key.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.
After the engine starts:
•On some engines, the WAIT TO
START light should illuminate
after the engine starts. Allow the
engine to idle about three
minutes or until the engine coolant temperature gauge begins to rise.
Maintain idle speed until the WAIT TO START light cycles off to
indicate the air intake heater has shut off (approximately six
minutes). Operating the engine at higher speeds will reduce the
effectiveness of the air inlet heater.
•Do not increase engine speed until the oil pressure gauge indicates
normal pressure (as indicated by the arrows); this should be indicated
on the gauge within 15 seconds after starting.
•Idle the engine for three to five minutes before operating with a full
load.
•Try to limit engine idle to 10 minutes. Excessive idling reduces fuel
economy.

•When starting a cold engine, increase the engine RPM slowly to make
sure adequate lubrication is available to the bearings.
Cold weather operation
WARNING:Do not use volatile starting aids such as ether,
propane or gasoline in the engine air intake system. Glow plugs
may ignite vapors which can cause engine damage or personal injury.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they’re in
optimum condition.
•Use a permanent-type engine coolant solution to protect the engine
against damage from freezing.
•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Make sure you use proper cold weather engine oil and that it is at its
proper level.
•At temperatures of –4°F (–20°C) or below, it is recommended that you
use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Note:Idling in cold weather will not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a build-up of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
Winter fronts
The use of winter fronts, or other air-restrictive devices mounted in front
of the radiator on vehicles with chassis-mounted charge air coolers, are
not recommended unless extremely cold weather conditions exist. Air
flow restriction can cause high exhaust temperatures, power loss,
excessive fan usage and a reduction in fuel economy. If you must use a
winter front, the device should have a permanent opening of at least 120
sq in. (774 sq. cm) directly in line with the fan hub.

Hot weather operation
•Keep the engine cooling system filled with a clean, permanent coolant
solution to protect against damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
Above normal coolant temperatures could be experienced while driving
in a transmission gear ratio which lugs the engine. To correct this
problem, engine speed should be increased by downshifting in to the
next lower gear to increase engine RPM.
Starting a turbocharged engine with the vehicle on a steep grade
When starting a diesel engine when the loaded vehicle is on a grade, the
engine RPM will start to fall slightly when the clutch is engaged; do not
disengage the clutch and try to increase engine RPM as this may damage
driveline components. The engine will recover as the vehicle begins
moving.
Engine shutdown
Allow the engine to idle for three to five minutes before shutting it
down. The larger the engine, the greater the need for this idling period.
However, do not let the engine idle for more than 10 minutes.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and Specificationschapter.
GENERAL OPERATING INSTRUCTIONS
•Avoid extended (more than 10 minutes) and unnecessary idling.
•Start the vehicle in motion by using the highest gear speed in the
transmission that will let the engine easily start the load without
slipping the clutch.
•Accelerate smoothly and evenly; rapid acceleration increases fuel
consumption without increasing engine performance.
•When approaching a hill, press the accelerator smoothly to start the
incline at full power, then shift down as needed to maintain vehicle
speed.
•When going down a hill, or long steep grades, prevent over-speeding
of the engine. The engine governor has no control over engine speed
when it is being pushed by a loaded vehicle.

The parking BRAKE warning lamp
in the instrument cluster illuminates
and will remain illuminated (when
the ignition is turned on) until the
parking brake is released.
Push the palm release lever on the
parking brake handle and push
down as far as possible to release
the brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
WARNING:If the parking
brake is fully released but
the parking brake warning lamp
remains illuminated, the brakes
may not be working properly. See
your dealer or a qualified service
technician.
The parking brake is not
recommended to stop a moving vehicle. However, if the normal brakes
fail, the parking brake can be used to stop your vehicle in an emergency.
Since the parking brake only applies retardation to the rear wheels, the
vehicle’s stopping distance will increase greatly and the handling of your
vehicle will be adversely affected.
POWER PARK (PARKING BRAKE) OPTION (IF EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulic-released driveline parking brake. It is controlled
by a yellow, dash-mounted parking brake knob.
The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),

TWO-SPEED REAR AXLE (IF EQUIPPED)
A two-speed rear axle allows the
driver to select a LO range for
greater pulling power and a HI
range for greater road speed and
fuel economy. These ranges can also
be used to provide additional steps
between transmission shifts when
driving on steep grades and/or fuel
economy may be factors.
Note:Do not shift between ranges
when the speed control is on.
WARNING:Never shift a two-speed axle when descending a
steep grade as this may cause loss of vehicle control and result
in personal injury.
Axle shifting
Manual transmissions:
•To downshift,select the next lower gear, release and press the
accelerator pedal rapidly, or while holding the accelerator pedal down,
release and engage the clutch rapidly.Note:The clutch method is
recommended when driving at slower speeds.
•To upshift,keep the accelerator pedal down, select the next higher
gear, release the accelerator and pause until the axle upshifts.Note:
De-clutch for smoother axle upshifts when driving at slower speeds.
Automatic transmissions:
•Use LO range for when you drive
a fully loaded vehicle on a severe
grade or in congested traffic. To
activate LO range, press the
upper portion of the switch.
•Use HI range for all normal
driving conditions with a lightly
loaded or partially loaded vehicle.
To activate HI range, press the
lower portion of the switch.
