parking brake FORD EXPEDITION 2021 Owner's Manual

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings could be worn-out, you should
have them checked. If the vehicle has
continuous vibration or shudder in the
steering wheel while braking, you should
have the system checked.
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. See Cleaning the Wheels
(page 358). See
Warning Lamps and
Indicators (page 115).
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. Switch the engine off, move the
transmission to park (P) and apply the
parking brake. Inspect the accelerator
pedal and the area around it for any items
or debris that may be obstructing its
movement. If none are found and the
condition persists, do not drive your vehicle.
Have your vehicle towed to the location
you are having it checked. Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist 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 anti-lock braking system may
be disabled. Have the system checked. If
the anti-lock brake system is disabled,
normal braking is still effective. If the brake warning lamp
illuminates with the parking
brake released, have your brake
system serviced immediately.
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.
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.
ELECTRIC PARKING BRAKE WARNING: Always fully apply the
parking brake and make sure you shift
into park (P). Failure to follow this
instruction could result in personal injury
or death. WARNING:
If you drive extended
distances with the parking brake applied,
you could cause damage to the brake
system. WARNING:
The electric parking
brake does not operate if the vehicle
battery is running out of charge.
Your vehicle has an electric parking brake.
You operate it with a switch instead of a
lever. The switch is on the center console
or to the left-hand side of the steering
wheel, on the lower part of the instrument
panel.
Note: The electric parking brake makes
noises during operation. This is normal.
Applying the Electric Parking
Brake Pull the switch upward.
The red warning lamp flashes
during operation and illuminates
when the parking brake is
applied. Note:
It remains illuminated for a short
period of time after you switch the ignition
off.
If it continues to flash or does not
illuminate, the system has malfunctioned.
Have your vehicle checked as soon as
possible.
Note: You can apply the electric parking
brake when the ignition is off.
Note: The electric parking brake could
automatically apply when you shift into park
(P). See
Transmission (page 203).
Applying the Electric Parking Brake in
an Emergency
Note: Do not apply the electric parking
brake when your vehicle is moving, except
in an emergency. If you repeatedly use the

Connect a booster battery to the vehicle
battery to release the electric parking brake
if the vehicle battery is running out of
charge. See Jump Starting the Vehicle
(page 314).
HILL START ASSIST WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
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. WARNING:
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
221
Expedition (TB8) Canada/United States of America, enUSA, First-Printing BrakesE267156 E270480 E267156 E267156 E270480

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.
Switching the System On and Off
Vehicles with Automatic Transmission
You cannot turn the system on or off.
When you switch the ignition on, the
system automatically turns on.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system.This
may cause reduced performance or false
alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
Note: Certain add-on devices installed
around the bumper or fascia may create
false beeps. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system.
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. See your
authorized technician. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings.
Note: The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation
(page 68).
We recommend that you take some time
to get to know the system and its
limitations by reading this section.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system automatically turns
on each time you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level. You can turn the system on or
off by pressing the parking aid
button. If your vehicle does not
have a parking aid button, the system can
be switched off through the information
display menu or from the pop-up message
that appears once you shift the
transmission into reverse (R). See General
Information
(page 119).
If a fault is present in the system, a warning
message appears in the information
display and does not allow you to switch
the system on. See
Information
Messages (page 129).
If a sensor is blocked and cannot function,
the system becomes disabled and a
warning message appears in the
information display. The system returns to
a normal state once the blockage is
cleared.
228
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Parking AidsE139213

When you shift into neutral (N), the system
only provides visual indication if your
vehicle is moving at a speed of
approximately 5 mph (8 km/h) or below,
for example, your vehicle is moving on a
slope, and the system detects an object
moving toward your vehicle. When you
stop your vehicle, visual indication stops
after four seconds.
SIDE SENSING SYSTEM
(IF
EQUIPPED) WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system.
The system uses the front and rear
outermost parking aid sensors to detect
objects that are near to the sides of your
vehicle. The system displays them on a
virtual map in the information display as
your vehicle moves past them.
The sensors are on the front and rear
bumpers. Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
The system may not function if:
• You switch the ignition on, off and back
on within a few seconds.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates.
Note: If you switch traction control off, the
side sensing system also turns off.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
To reinitialize the system, you may have to
drive your vehicle approximately
10 ft
(3 m). The sensor coverage area is up to
24 in
(60 cm) from the side of your vehicle.

WARNING: Active park assist does
not apply the brakes under any
circumstances. WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death.
Active park assist is a multi-step process
and may require you to shift the
transmission multiple times. Follow the
onscreen instructions until the parking
maneuver is complete.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel, or by taking full control of
your vehicle after pressing the active park
assist button.
Keep your hands, hair, clothing and any
loose items clear of the steering wheel
when using active park assist.
The sensors are on the front and rear
bumpers.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
The sensors may falsely detect objects due
to ultrasonic interference caused by
motorcycle exhausts, truck air brakes or
horns, for example.
Note: If you change any tires, the system
must recalibrate and may not correctly
operate for a short time. The system may not correctly operate in
any of the following conditions:
•
You use a spare tire or a tire that is
significantly worn more than the other
tires.
• One or more tires are incorrectly
inflated.
• You try to park on a tight curve.
• Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.
• The edge of the neighboring parked
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.
• The weather conditions are poor. For
example, during heavy rain, snow, fog,
high humidity and high temperatures.
Do not use the system if:
• You have attached an add-on
accessory close to the sensors on the
front or rear of your vehicle. For
example, a bike rack or trailer.
• You have attached an overhanging
object to the roof. For example, a
surfboard.
• The front bumper, rear bumper or the
side sensors are damaged.
• The correct tire size is not in use on your
vehicle. For example, a mini-spare tire.

Parallel Parking
The system detects available parallel
parking spaces and steers your vehicle into
the space. You control the accelerator,
gearshift and brakes. The system visually
and audibly guides you into a parallel
parking space. Press the button once to search
for a parking space.
Note: You can also switch the system on
after you have already driven partially or
completely past a parking space. Press the
active park assist button and the system
informs you if you have recently passed a
suitable parking space. When the vehicle speed is less than
22 mph (35 km/h), the system scans both
sides of your vehicle for an available
parking space. A message and a graphic
appear in the information display to
indicate the system is searching for a
parking space. Use the direction indicator
lever to search for a parking space on the
driver or passenger side of your vehicle.
Note:
The system scans both sides of your
vehicle and offers parking spaces one side
at a time if you do not use the direction
indicator.
Note: The system defaults to the passenger
side if you do not use the direction indicator. Drive your vehicle approximately 3 ft (1 m)
and parallel to the other parked vehicles
when searching for a parking space.
Note:
If you drive your vehicle less than 2 ft
(0.5 m)
or greater than 5 ft (1.5 m) away
from other parked vehicles, the system may
not be able to detect an available parking
space.
When the system detects a suitable space,
a message displays and a tone sounds.
Stop your vehicle and follow the onscreen
instructions. If your vehicle is moving very
slowly, you may have to move forward a
short distance before the system is ready
to park.
Note: You must observe that the space the
system selects remains clear of obstructions
at all times during the maneuver.
Note: The system always offers the last
parking space it detects. For example, if your
vehicle detects multiple spaces when you
are driving, it offers the last one.
235

Note:
If the vehicle speed is greater than
approximately 22 mph (35 km/h), the
system shows a message to instruct you to
reduce the vehicle speed.
Automatically Steering into a Parallel
Parking Space
When you shift into reverse (R), with your
hands off the steering wheel and nothing
obstructing its movement, your vehicle
steers itself into the space. The system
displays instructions to move your vehicle
backward and forward in the space.
Note: If the vehicle speed exceeds
approximately
6 mph (9 km/h), you
interrupt the maneuver, or the system
switches off, you must take full control of
your vehicle.
Note: If the system detects an object is very
close to your vehicle and it may be unsafe
to continue the maneuver, it may instruct
you to stop your vehicle. The system may
not provide any further instruction. Steering
assistance continues to operate but you
must decide if it is safe to continue the
maneuver. When you believe your vehicle is correctly
parked, or a solid tone sounds and an
information message appears, bring your
vehicle to a complete stop.
When the Active Park Assist maneuver is
