If the fuel cap warning lamp remains on,
at the next opportunity, safely pull off of
the road, remove the fuel filler cap, align
the cap properly and reinstall it. The check
fuel cap warning lamp or warning message
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.
Fuel Fill Rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to 20 gal (75 L) per
minute from a fuel-dispensing nozzle.
Pumping fuel at greater flow rates may
result in premature nozzle shut-off or spit
back.
Truck stops have fuel pumps and nozzles
designed for larger, heavy-duty trucks. If
you are refueling your vehicle at a truck
stop and the nozzle shuts off repeatedly,
wait 5-10 seconds, then use a slower fill
rate.
FUEL CONSUMPTION
Real world fuel consumption is governed
by many factors, for example driving style,
high speed driving, stop-start driving, air
conditioning usage, the accessories fitted,
payload and towing. •
The usable capacity of the fuel tank is
the amount of fuel that can be added
into the tank after the gauge indicates
empty.
• The advertised capacity is the total fuel
tank size. See
Capacities and
Specifications (page 252). It is the
combined usable capacity plus the
empty reserve.
• Due to the empty reserve, you may not
be able to refuel the full amount of the
advertised capacity of the fuel tank
even when the fuel gauge reads empty.
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. The amount of usable
fuel in the empty reserve varies and should
not be relied upon to increase driving range.
Filling the Tank
For consistent results when filling the fuel
tank:
• Turn the ignition off before refueling
your vehicle; a temporary inaccurate
reading may result if the engine is left
on when refueling your vehicle.
• Use the same fill rate
(low-medium-high) each time the tank
is refueled.
• Allow no more than two automatic
click-offs when refueling your vehicle.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first
900 mi (1,500 km) of driving (this is
your engine ’s break-in period); a more
accurate measurement is obtained after
1,900 mi (3,000 km)
.
Fuel expense, frequency of fill ups or fuel
gauge readings are not accurate ways to
measure fuel economy.

In the United States, federal law and
certain state laws prohibit removing or
rendering the emission control system
inoperative. Similar federal or provincial
laws may apply in Canada. We do not
recommend any vehicle modification
without determining applicable law.
Tampering with emissions
control system, including related
sensors or the diesel exhaust
fluid injection system can result in reduced
engine power and the service engine soon
warning lamp illuminating in the
information display.
Tampering with a Noise Control
System
Federal law prohibits the following acts or
the causing thereof:
• The removal or rendering inoperative
by any person other than for purposes
of maintenance, repair or replacement
of any device or element of design
incorporated into any new vehicle for
the purpose of noise control prior to its
sale or delivery to the ultimate
purchaser or while it is in use.
• The use of the vehicle after such device
or element of design has been removed
or rendered inoperative by any person.
Among those acts, which the United States
Environmental Protection Agency may
presume to constitute tampering are the
acts listed below:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer ’s
specifications. The complexity of the diesel engine makes
it so the owner is discouraged from
attempting to perform maintenance other
than the services described in this Owner's
Manual.
If you experience difficulty starting the
engine, rough idling, excessive exhaust
smoke, a decrease in engine performance
or excess fuel consumption, perform the
following checks:
•
A plugged or disconnected air inlet
system or engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Check engine oil level.
• Wrong fuel or oil viscosity for the
climatic conditions.
If these checks do not help you correct the
engine performance problem you are
experiencing, have your vehicle checked
as soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on vehicles weighing over
10,000 lb (4,536 kg) Gross Vehicle Weight
Rating. The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg) Gross Vehicle Weight
Rating.

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
500 mi
(800 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications
(page
258).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
GENERAL DRIVING POINTS
General Information
• 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, and then shift
down as needed to maintain vehicle
speed.
• When going down a hill, or long steep
grades, prevent overspeeding of the
engine. Normally, choose the same
gear to descend the hill that you use to
ascend the hill. The engine governor
has no control over engine speed when
it is being pushed by a loaded vehicle. •
Do not operate in a gear that permits
an engine speed more than the
maximum governed speed or high-idle
RPM (no load).
• Always shift to a lower gear at high
altitudes to prevent engine smoking.
Backing Up WARNINGS
All vehicles have blind spots. To
reduce the risk of severe injury or
property damage, never move your
vehicle to the side or rear or change lanes
without being sure your way is clear on
both sides and to your rear. To reduce the risk of the possibility
of personal injury while backing up
the vehicle, always be sure your
vehicle ’s path is clear. Before backing up your vehicle, be sure you
can do so safely. If anything behind the cab
limits your view, do not rely on mirrors
alone to make sure that your intended path
is clear. If other people are in the vicinity,
have someone standing well behind your
vehicle and outside of your intended path
(visible through an exterior mirror) guide
you as you back up.
Although OSHA or some governmental
regulations may require the use of an
electrical or mechanical back up alarm to
warn bystanders, such an alarm does not
guarantee that the intended path is clear.
When in doubt, get out of your vehicle and
visually check the intended path is clear.
Back up slowly as to allow others time to
move, if necessary.
If you install an electrical back up alarm,
connect it to the backup lamp circuit.

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the
coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
information display may display a message
to change coolant at this time. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 252). Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle is equipped with an engine
driven cooling fan drive (also called a fan
clutch). This fan drive changes the fan
speed to match the vehicle
’s changing
cooling air flow requirements. Fan speed,
fan noise level and fuel consumption all
will increase based on the driving
conditions that include trailer towing, hill
climbing, heavy loads, high speed and high
ambient temperature, individually or in
combination.
The fan drive is designed to provide the
minimum fan speed (and resulting
minimum fan noise and fuel consumption)
required to meet the ever changing vehicle
cooling air flow requirements. You will hear
the amount of fan noise increasing and
decreasing as the engine power
requirements and vehicle driving conditions
change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
coolant temperature gauge moves toward
the red zone: A warning lamp illuminates and
a message may appear in the
information display.

•
Robinair® Coolant and Battery
Refractometer 75240 –
Recommended refractometer to test
coolant concentration. (Rotunda tool
part number: ROB75240).
• Rotunda 328-R071–ELC (Antifreeze
Coolant ELC Contamination Kit)
–
Evaluates the corrosion inhibitor
additive strength. Note the first step is
to verify the vehicle ’s coolant
concentration is in the correct range of
40 – 60%. Coolant concentrations
outside this range will not provide valid
test results. If the report results in a
pass, for example the cooling system
does not show excessive
contamination, the corrosion inhibitor
additive strength is sufficient, and no
action is required. If the report results
as insufficient (does not pass), the
corrosion inhibitor additive strength of
the coolant is too low. If the engine
cooling system corrosion inhibitor
additive strength is low, add
47 fl oz
(1.4 L) of Motorcraft Specialty Orange
Engine Coolant Revitalizer. If the
secondary cooling system corrosion
inhibitor additive strength is low, add
16 fl oz (0.47 L) of Motorcraft Specialty
Orange Engine Coolant Revitalizer.
• Motorcraft Specialty Orange Engine
Coolant Revitalizer
– Additive to
boost the corrosion inhibitor level
based upon the test results of the
Antifreeze Coolant ELC Contamination
Kit. The Revitalizer may be added two
times over the life of the coolant. If
additional dosages are required, the
cooling system must be flushed and
refilled per the instructions in the
Workshop Manual.
Make sure to follow the proper coolant and
additive specifications. See
Capacities
and Specifications (page 252). Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
information display may display a message
to change coolant at this time. Add
prediluted coolant approved to the correct
specification. See
Capacities and
Specifications (page 252).

Clutch)
Your vehicle may have an engine driven
cooling fan drive (also called a fan clutch).
This fan drive changes the fan speed to

flow requirements. Fan speed, fan noise
level and fuel consumption all will increase
based on the driving conditions that

and should normally decrease after driving
for a short time.
AUTOMATIC TRANSMISSION
FLUID CHECK
The transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
for example if the transmission slips, shifts
slowly or if there are signs of fluid loss.
