System Operation
The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below.
Pro Trailer Backup Assist™ System is Not
Available or Trailer Reverse Guidance
System is Not Available:
• The system relies on many
sub-systems in your vehicle to correctly
operate. If those sub-systems are not
correctly operating, the system may
not be available.
• Low battery voltage is a condition that
prevents the system from operating.
Please make sure the battery is
correctly charged if the system is not
available.
• You may need to drive your vehicle
straight forward above
25 mph
(40 km/h) before the system is
available again.
• If the message continues to display,
see your authorized dealer for service.
Pro Trailer Backup Assist™ Driving
Required to Initialize Steering Press Knob
to Exit or Trailer Reverse Guidance Driving
Required to Initialize Steering Press OK to
Exit:
• The steering system needs to learn
internal parameters to fully enable the
feature. Drive your vehicle straight
forward above
25 mph (40 km/h) for
approximately 5 minutes.
• This may occur when your vehicle is
new, the battery voltage is too low, the
battery has been disconnected or your
steering system has been serviced. Sticker lost:
•
If the system cannot initially find the
sticker, it may be necessary for you to
change the lighting conditions by
moving the vehicle and trailer or
waiting until conditions change.
• Check for the following if you receive
the lost sticker message while using
the system.
• Stop your vehicle as soon as the
message displays.
• Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.
• Clean the sticker and camera to make
sure they are unobstructed.
• Clean the lens with a soft, lint-free
cloth and water.
• Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the
sticker, and then wipe clean with a soft
cloth.
• Remove any items that may be
blocking the view of the sticker.
Depending on your trailer configuration
and any equipment mounted to your
trailer, it is possible for the sticker to be
blocked from view of the camera as it
rotates on the hitch ball but not be
blocked during setup. Remove the
obstruction if possible. It may be
necessary to remove the sticker from
its current location if the obstruction
cannot be cleared. Place a new sticker
that is visible to the camera in all
positions of the trailer behind your
vehicle.

ENGINE COOLANT CHECK -
6.2L
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 565).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We
recommend Robinair® Coolant and
Battery Refractometer 75240 (Rotunda
tool part number: ROB75240). We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the engine cooling or
heating systems. Resulting component
damage may not be covered by the vehicle
Warranty.
Adding Coolant WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
It is very important to use prediluted
coolant meeting the correct specification
in order to avoid plugging the small
passageways in the engine cooling system.
See
Cooling System Capacity and
Specification (page 456). Incorrect
prediluted coolant use can cause damage
not covered by the vehicle Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Maintenance

•
Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE EXHAUST -
6.7L DIESEL WARNING: Failure to maintain the
functional holes, in the tailpipe section
of the exhaust, clean and free of debris
or foreign material may result in the
holes becoming blocked or plugged. Do
not modify or remove the tail-pipe
section. Blocked or plugged holes or
removal/modification of the system
could result in elevated exhaust gas
temperatures which may result in
vehicle/property damage or personal
injury. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter and/or the diesel
particulate filter (DPF). The diesel
oxidation catalytic converter and/or the
DPF heats up to a high temperature after
only a short period of engine operation
and can stay hot even after the engine
is turned off. Failure to follow these
instructions may result in personal injury. The visible holes in the exhaust tip and the
holes under the shield just inboard of the
right rear tire(s) are functional. The holes
need to be kept clear of mud/debris or
foreign material to maintain proper
function of the exhaust system. Clean and
remove debris or foreign material if present
as needed. Spraying with a hose during
regular washing of vehicle should help
keep holes clean and clear of debris or
foreign material.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.

If a crash deploys an airbag, excluding knee
airbags and rear inflatable seatbelts, or
activates the fuel pump shut-off, your
vehicle may be able to contact emergency
services by dialing 911 through a paired and
connected Bluetooth®-enabled phone.
See
Supplementary Restraints System
(page 45). Important information about
airbag deployment is in this chapter.
See
Roadside Emergencies (page 325).
Important information about the fuel pump
shut-off is in this chapter.
Setting 911 Assist On or Off
Press the Settings button then select: Action and Description
Menu
Item
Select the desired option, on
or off.
911 Assist
To make sure that 911 Assist works
properly:
• SYNC must be powered and working
properly at the time of the incident and
throughout feature activation and use.
• The 911 Assist feature must be set on
before the incident.
• You must pair and connect a
Bluetooth®
enabled and compatible
cell phone to SYNC.
• A connected
Bluetooth® enabled
phone must have the ability to make
and maintain an outgoing call at the
time of the incident.
• A connected
Bluetooth® enabled
phone must have adequate network
coverage, battery power and signal
strength.
• The vehicle must have battery power
and be located in the U.S., Canada or
in a territory in which 911 is the
emergency number. In the Event of a Crash
Not all crashes deploy an airbag or activate
the fuel pump shut-off (the triggers for 911
Assist). If a connected cell phone sustains
damage or loses its connection to SYNC
during a crash, SYNC searches for and tries
to connect to a previously paired cell
phone; SYNC then attempts to call the
emergency services.
Before making the call:
•
SYNC provides a short window of time
(about 10 seconds) to cancel the call.
If you fail to cancel the call, SYNC
attempts to dial 911.
• SYNC says the following, or a similar
message: "SYNC will attempt to call
911, to cancel the call, press Cancel on
your screen or press and hold the
phone button on your steering wheel".
If you do not cancel the call, and SYNC
makes a successful call, a pre-recorded
message plays for the 911 operator, and
then the occupant(s) in your vehicle are
able to talk with the operator. Be prepared
to provide your name, phone number and
location immediately, because not all 911
systems are capable of receiving this
information electronically.
911 Assist May Not Work If
• Your cellular phone or 911 Assist
hardware sustains damage in a crash.
• The vehicle's battery or the SYNC
system has no power.
• The phone(s) thrown from your vehicle
are the ones paired and connected to
the system.

(If Equipped)

AUXILIARY SWITCHES (IF
EQUIPPED)
For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
• When adding accessories, equipment,
passengers and luggage to your
vehicle, do not exceed the total weight
capacity of the vehicle or of the front
or rear axle (GVWR or GAWR as
indicated on the Safety Compliance
Certification label). Ask an authorized
dealer for specific weight information.
• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems
equipped with radio transmitters, for
example, two-way radios, telephones
and theft alarms. Any such equipment
installed in your vehicle should comply
with Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulations, and
should be installed by an authorized
dealer.
• An authorized dealer needs to install
mobile communications systems.
Improper installation may harm the
operation of your vehicle, particularly
if the manufacturer did not design the
mobile communication system
specifically for automotive use.
• If you or an authorized Ford dealer add
any non-Ford electrical or electronic
accessories or components to your
vehicle, you may adversely affect
battery performance and durability. In
addition, you may also adversely affect
the performance of other electrical
systems in the vehicle. The auxiliary switch option package
provides six switches mounted in the
overhead console. These switches operate
when the vehicle is running or from battery
power, depending on the switchable fuse
AUXF4's location in the upfitter relay box.
We recommend, however, that the engine
remain running to maintain battery charge
when using the auxiliary switches for
extended periods of time or higher current
draws.
Note:
When your vehicle has a diesel
engine, use the auxiliary switches only when
the engine is running. The glow plugs also
drain battery power when the ignition key is
in the on position. Using the auxiliary
switches, even for limited amounts of time,
can cause your battery to drain quickly and
prevent your vehicle from restarting.
When switched on, the auxiliary switches
provide electrical battery power for a
variety of personal or commercial uses.
Switches 1 through 4 provide 25 amps.
Switches 5 and 6 provide 40 amps.
The relay box for the auxiliary switches is
in the rear of the engine compartment,
near the back wall. See your authorized
dealer for service.
The relays are coded as shown:
