ABOUT THIS MANUAL
Thank you for choosing Ford. We
recommend that you take some time to
get to know your vehicle by reading this
manual. The more that you know about
your vehicle, the greater the safety and
pleasure you will get from driving it.
WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving.
Note: Always use and operate your vehicle
in line with all applicable laws and
regulations.
Note: Pass on this manual when selling
your vehicle. It is an integral part of your
vehicle.
Note: Your vehicle ’s powertrain control
systems can detect and store information
about vehicle modifications that increase
horsepower and torque output such as
whether or not performance-enhancing
powertrain components commonly referred
to as performance chips have been used.
This information will stay in the system ’s
memory and cannot be erased even if the
modification is removed. Ford Motor
Company, Ford of Canada, Ford of Mexico
and service or repair facilities can retrieve
this information when servicing your vehicle.
Ford Motor Company may use this
information to determine if your warranty
covers any needed repairs. Note:
Some aftermarket products may
cause severe engine/transmission and/or
exhaust system damage; refer to your
warranty information for more information.
Your new diesel engine will feel, drive and
function somewhat differently than a
gasoline engine. Therefore it is very
important that you read and thoroughly
familiarize yourself and others operating
the vehicle with this guide. There is a
special procedure for turning off the diesel
engine. See Starting a Diesel Engine
(page 95). It is important to read and
understand this material in order to
maintain the best service life for your
engine.
Ford may discontinue models or change
specifications without any notice and
without incurring obligations.
Note: Either Ford Motor Company or an
authorized Ford dealer may have originally
sold this incomplete vehicle to a vehicle
modifier who upfitted it. As a result, some
of the options and features on this vehicle
may differ from what we describe in this
manual.
This manual may qualify the location of a
component as left-hand side or right-hand
side. The side is determined when facing
forward in the seat.

F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Introduction

If these modified engine performance
characteristics persist for an extended
period and either the service engine soon
or powertrain malfunction, reduced power,
electronic throttle control light is
illuminated, have the system checked by
an authorized dealer.
Service engine soon
Powertrain malfunction, reduced
power, electronic throttle control
Diesel Lubrication System
It is important to change the engine oil at
the recommended service intervals or
when indicated by the information display
to maintain oil viscosity. Extending the oil
and filter change interval beyond the
recommended interval can negatively
affect engine performance, fuel economy
and engine life. See Engine Oil Check
(page 218).
Engine and secondary cooling system
The cooling system contains a primary
cooling loop to cool the engine and a
secondary cooling loop to cool the
transmission, charge air, and fuel. The
coolant serves three primary purposes: to
provide heat transfer, freeze point
protection, and corrosion protection using
additives.
Vehicles with diesel engines typically are
used to carry heavy loads and accumulate
mileage rapidly. These two factors may
cause the additives in the coolant to wear
out in a shorter time. You can find more
information about coolant additives and
coolant change intervals in the coolant
chapter. See
General Maintenance
Information (page 319). Operating the
engine with insufficient coolant or coolant
additive can cause severe engine damage. Selective catalytic reduction system
Your vehicle is equipped with a selective
catalytic reduction system designed to
reduce emission levels of nitrogen oxides
from the exhaust of your diesel engine. This
system relies on the use of Diesel Exhaust
Fluid (DEF) that you must replenish at
certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes
contaminated will result in vehicle speed
limitations or result in your vehicle entering
an idle-only mode. See
Selective
Catalytic Reductant System (page 112).
Minor Troubleshooting Guide
If the engine won ’t crank WARNING:
Battery posts,
terminals and related accessories
contain lead and lead compounds. Wash
hands after handling.
Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to the start position, the lights
become dim or go out, the battery
connections may be loose or corroded, or
the battery may be discharged. If there is
a clicking or stuttering sound coming from
the engine compartment when you turn
the key to the start position, this may also
indicate a loose or corroded battery
connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.
