Ford Super Duty (2018 year). Manual — part 56

GENERAL INFORMATION

Note: Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.

Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise.

E144522

See Warning Lamps and
Indicators (page 108).

Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.

Brake Over Accelerator

In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Shift the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.

Brake Assist

Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.

Anti-lock Brake System

This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.

This lamp momentarily
illuminates when you switch the
ignition on. If the light does not

illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective.

E144522

If the brake warning lamp
remains illuminated after you
release the parking brake, have

the system checked by an authorized
dealer.

It also illuminates momentarily when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer.

Diesel Engine Exhaust Braking

(If

Equipped)

WARNINGS

Do not use tow/haul when the road
surface is slippery. Failure to follow
this instruction could result in the

loss of control of your vehicle.

Do not use diesel engine exhaust
braking when the road surface is
slippery. Failure to follow this

instruction could result in the loss of
control of your vehicle.

This feature increases engine braking at
higher engine speeds to provide better
grade descent control with less brake and
transmission wear and tear.

Note: Use this when driving downhill and
carrying heavy loads or trailering.

Benefits of engine braking are:
•

Lower brake temperature.

•

Reduced brake fade.

•

Longer brake life.

•

Improved driving and trailering control.

E171217

Press the button on the switch
bank next to the audio unit to
switch the system on or off.

There are two engine brake modes, manual
and automatic.

Manual Engine Braking

1.

Press the button to switch on manual
engine braking.

2. Release the accelerator pedal to

maximize engine braking.

3. Apply the brakes. The transmission

downshifts to lower gears.

Note: The engine braking feature only
functions when you release the accelerator.

Note: You can shift the transmission to
lower gears with progressive range selection
(PRS) or manual shifting independent of
pressing the brakes.

Note: You can also use manual engine
braking with cruise control to improve grade
descent control.

Note: If your vehicle has Adaptive Cruise
Control, the speed control system uses the
selected engine brake mode, transmission
gears, and brakes to maintain the set speed
and distance to the vehicle being followed.

Automatic Engine Braking

1.

Press the button twice to switch on
automatic engine braking.

2. Release the accelerator or brake pedal.

The system remembers your vehicle
speed.

Note: This feature offers smoother, less
aggressive engine braking during downhill
descents. It may not apply braking if the
vehicle speed is not increasing, although it
will apply full engine braking force when
needed to prevent acceleration. The system
automatically activates the engine brake
and, if necessary, downshifts the
transmission to lower gears to not exceed
your vehicle's set speed when the brake or
accelerator were last released.

Warning Lamp Conditions

•

Illuminates when this feature is
switched on and the system is
operating properly. See Warning
Lamps and Indicators (page 108).

•

Flashes when the engine brake is
disabled due to a fault or the engine
does not meet the required braking
conditions.

•

Does not illuminate when the switch
or indicator is faulty.

You can switch the system on at anytime.
The system becomes active once the
braking conditions are met.

Braking Conditions

•

Your vehicle is in a forward gear.

•

The engine speed is above about 1500
RPM.

•

Your foot is off the accelerator.

You can use this feature with tow/haul or
progressive range selection to provide
further increased engine braking. The
transmission automatically upshifts to
prevent the engine from entering the red
zone on the tachometer. See Automatic
Transmission (page 210).

HINTS ON DRIVING WITH
ANTI-LOCK BRAKES

The anti-lock braking system does not
eliminate the risks when:
•

You drive too closely to the vehicle in
front of you.

•

Your vehicle is hydroplaning.

•

You take corners too fast.

•

The road surface is poor.

Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.

PARKING BRAKE

WARNING

Always set the parking brake fully
and make sure the transmission is
placed in park (P). Failure to set the

parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. Turn the ignition to the lock
position and remove the key whenever you
leave your vehicle.

Apply the parking brake whenever your
vehicle is parked. Press the pedal
downward to set the parking brake. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.

To release, pull the brake release lever
located at the lower left side of the
instrument panel.

If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.

HILL START ASSIST

WARNINGS

The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking

brake.

You must remain in your vehicle
when the system turns on. At all
times, you are responsible for

controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death.

The system will turn off if a
malfunction is apparent or if you rev
the engine excessively. Failure to

take care may result in the loss of control
of your vehicle, serious personal injury or
death.

The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.

When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes

automatically once the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.

The system activates on any slope that
causes your vehicle to roll.

Note: There is no warning light to indicate
the system is either on or off.

Using Hill Start Assist

1.

Press the brake pedal to bring your
vehicle to a complete standstill.Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.

2. If the sensors detect that your vehicle

is on a slope, the system activates
automatically.

3. When you remove your foot from the

brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.

4. Drive off in the normal manner. The

system releases the brakes
automatically.

Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
