chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it cannot stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Anti-Lock Braking System
Limitations (page 240). Note:
Excessive tire slippage can cause
transmission damage.

BRAKE PRECAUTIONS
WARNING: Driving your vehicle
with the warning lamp on is dangerous.
A significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
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.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash 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 could pulse and could travel further.
Maintain pressure on the brake pedal.
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. Move 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.
LOCATING THE BRAKE FLUID
RESERVOIR
See
Under Hood Overview (page 397).
CHECKING THE BRAKE FLUID WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir.

1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative
to the MIN and the MAX marks on the
reservoir.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our
specifications. See Brakes (page 240).

TROUBLESHOOTING
BRAKES – WARNING LAMPS If the ABS indicator illuminates
when you are driving, this
indicates a malfunction. Your
vehicle continues to have normal braking
without the anti-lock braking system
function. See an authorized dealer.
It also momentarily illuminates 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. The brake indicator momentarily
illuminates when you switch the
ignition on to confirm the lamp
is functional. It may also illuminate when
you apply the parking brake and the
ignition is on. If it illuminates when your
vehicle is moving, make sure the parking
brake is disengaged. If the parking brake
is disengaged, this indicates low brake fluid
level or a brake system fault. See an
authorized dealer.
BRAKES – FREQUENTLY ASKED
QUESTIONS
Is it normal for my brakes to make
noise?
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding,
or continuous squeal sound is present,
the brake lining could be worn-out.
Have the system checked by an
authorized dealer.

2022 Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202103, First-Printing BrakesE170684 E270480

There is an electrical motor sound
when I press on the brake pedal or
activate the park brake switch. Is this
normal?
Yes, those sounds are the electronic
brake booster or the electronic park
brake operating.
Note: Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning Wheels (page
422).

APPLYING THE PARKING
BRAKE
WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death.
Apply the parking brake whenever you park
your vehicle. Press the pedal downward to
set the parking brake. The brake warning
lamp in the instrument cluster will
illuminate and remains illuminated until
you release the parking brake. 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 service or the
vehicle may be overloaded.

DIESEL ENGINE EXHAUST
BRAKE – PRECAUTIONS
WARNING: 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. WARNING:
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.
USING THE DIESEL ENGINE
EXHAUST BRAKE
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. 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.
Braking conditions must be met to use
exhaust brake:
• Your vehicle is in a forward gear.
• The engine speed is above 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 upshifts to prevent the engine
from entering the red zone on the
tachometer.
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.
