WINDSHIELD WIPERS
Note:
Fully defrost the windshield before
you switch the windshield wipers on.
Note: Make sure you switch the windshield
wipers off before entering a car wash.
Note: If streaks or smears appear on the
windshield, clean the windshield and the
wiper blades. If that does not resolve the
issue, install new wiper blades.
Note: Do not operate the wipers on a dry
windshield. This may scratch the glass,
damage the wiper blades or cause the wiper
motor to burn out. Always use the
windshield washers before wiping a dry
windshield. •
Rotate away from you for a long wipe
interval.
• Rotate toward you for a short wipe
interval.
Speed Dependent Wipers
When your vehicle speed increases, the
interval between wipes decreases.
AUTOWIPERS (IF EQUIPPED)
Note: Fully defrost the windshield before
you switch the windshield wipers on. Note:
Make sure you switch the windshield
wipers off before entering a car wash.
Note: If streaks or smears appear on the
windshield, clean the windshield and the
wiper blades. If that does not resolve the
issue, install new wiper blades.
Note: The courtesy wipe feature turns on
after using the windshield washers to
remove any excess washer fluid and debris.
You can adjust the courtesy wipe settings
in the instrument display.
Wet or winter driving conditions with ice,
snow or salty road mist can cause
inconsistent and unexpected wiping or
smearing. Use the rotary control to adjust the
sensitivity of the autowipers. When you
select low sensitivity, the wipers operate
when the sensor detects a large amount
of water on the windshield. When you
select high sensitivity, the wipers operate
when the sensor detects a small amount
of water on the windshield.
Keep the outside of the windshield clean.
The rain sensor is very sensitive and the
wipers may operate if dirt, mist or insects
hit the windshield.

Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
WASHER FLUID CHECK WARNING: If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 441).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.
FUEL FILTER - 6.2L/7.3L
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed. CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
You can manually move the wiper arms
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.
1. Pull the wiper blade and arm away
from the glass.
382
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- MaintenanceE142463 E165804

2. Release the wiper blade lock (A) and

into place. Lower the wiper arm and blade
back on the windshield. The wiper arms will
automatically return to their normal position
when you turn the ignition on.
• Replace wiper blades at least once per
year for optimum performance.
• You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
CHANGING A BULB WARNING: Switch the lamps and
the ignition off. Failure to follow this
warning could result in serious personal
injury. WARNING: Bulbs can become hot.
Let the bulb cool down before removing

•
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.
394
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Vehicle CareE163380

To clean the windshield and wiper blades:
•
Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
CLEANING THE INTERIOR WARNING: Do not use cleaning
solvents, bleach or dye on the vehicle's
seatbelts, as these actions may weaken
the belt webbing. WARNING:
On vehicles equipped
with seat-mounted airbags, do not use
chemical solvents or strong detergents.
Such products could contaminate the
side airbag system and affect
performance of the side airbag in a crash. For fabric, carpets, cloth seats and seats
equipped with side airbags:
•
Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.
Note: Cashmere and microfiber cloth fabric
is made of polyester microfiber with
micro-porous polyurethane. Using
commercially available fabric cleaners can
cause permanent damage.
Note: Do not use commercially available
leather and vinyl cleaning products on
cashmere or microfiber cloth fabric.
Note: Your vehicle may have cashmere or
microfiber cloth fabric on the seats,
headliner, floor mats and door panels.
Depending on the type of stain, use water,
lemon juice or pure ethyl alcohol when
cleaning. For cleaning microfiber cloth,
refer to the following chart:
