Ford Super Duty (2018 year). Manual — part 21

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.

E172816

•

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.

E172817

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.

In these conditions, you can do the
following:
•

Lower the sensitivity of the autowipers
to reduce the amount of smearing on
the windshield.

•

Switch to normal or high-speed wipe.

•

Switch autowipers off.

WINDSHIELD WASHERS

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 washer before wiping a dry
windshield.

Note: Do not operate the washers when
the washer reservoir is empty. This may
cause the washer pump to overheat.

E172818

•

A brief press causes a single wipe
without washer fluid.

•

A brief press and hold causes the
wipers to swipe three times with
washer fluid.

•

A long press and hold turns on the
wipers and washer fluid for up to 10
seconds.

A wipe occurs a few seconds after washing
to clear any remaining washer fluid. You
can switch this feature on or off in the
information display.

GENERAL INFORMATION

Condensation in the Exterior Front
Lamps and Rear Lamps

Exterior front lamps and rear lamps have
vents to accommodate normal changes
in air pressure.

Condensation can be a natural by-product
of this design. When moist air enters the
lamp assembly through the vents, there is
a possibility that condensation can occur
when the temperature is cold. When
normal condensation occurs, a fine mist
can form on the interior of the lens. The
fine mist eventually clears and exits
through the vents during normal operation.

Clearing time may take as long as 48 hours
under dry weather conditions.

Examples of acceptable condensation are:
•

The presence of a fine mist (no streaks,
drip marks or large droplets).

•

A fine mist covers less than 50% of the
lens.

Examples of unacceptable condensation
are:
•

A water puddle inside the lamp.

•

Streaks, drip marks or large droplets
present on the interior of the lens.

If you see any unacceptable condensation,
have your vehicle checked by an authorized
dealer.

AUTOLAMPS

(If Equipped)

WARNING

The system does not relieve you of
your responsibility to drive with due
care and attention. You may need to

override the system if it does not turn the
headlamps on in low visibility conditions,
for example daytime fog.

E142451

When the lighting control is in the
autolamps position, the headlamps turn
on in low light situations, or when the
wipers turn on.

The headlamps remain on for a period of
time after you switch the ignition off. Use
the information display controls to adjust
the period of time that the headlamps
remain on.

Note: If you switch the autolamps on, you
cannot switch the high beams on until the
system turns the low beams on.

Windshield Wiper Activated
Headlamps

When you switch the autolamps on, the
headlamps turn on within 10 seconds of
switching the wipers on. They turn off
approximately 60 seconds after you switch
the windshield wipers off.

The headlamps do not turn on with the
wipers:
•

During a single wipe.

•

When using the windshield washers.

•

If the wipers are in intermittent mode.

Note: If you switch the autolamps and the
autowipers on, the headlamps turn on when
the windshield wipers continuously operate.
