2018 FORD EXPEDITION parking brake

PRINCIPLE OF OPERATION
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
Hill descent control
does not provide hill hold at zero miles
per hour (0 kilometers per hour). When
stopped, you must apply the parking
brake or place the vehicle in P (Park), or
it may roll away.
Hill descent control allows you to set and
maintain vehicle speed while descending
steep grades in various surface conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but you cannot use the system to
set or maintain the descent speed.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system provides a
warning in the message center and a tone
sounds when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button on the
instrument panel. The button
illuminates and a chime sounds when you
switch this feature on.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent
speed, press the brake pedal until you
reach the desired speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill Descent Modes
• At speeds between
2 mph (3 km/h)
and 20 mph (32 km/h): When you
press this button, the light flashes
indicating this feature is active. Your
vehicle maintains the speed you desire
while in this mode.
• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): When you
press this button, the light is solid and
a message appears in the information
display indicating this feature is active.
Your vehicle does not maintain the
speed you desire and you cannot set
your descent speed.

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 61).
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 111).
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 123).
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.

available until you have driven
approximately the length of your vehicle
in order for the system to reinitialize if:
•
You switch the ignition on, off and back
on.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system is
activated.
• The traction control system is
activated.
• When the steering wheel angle
information is not available, the side
sensing system is not available. The
vehicle must be driven at least 492 ft
(150 m) above 19 mph (30 km/h) to
recover the steering wheel angle
information.
ACTIVE PARK ASSIST
(IF
EQUIPPED) 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 sensors may not
detect objects in heavy rain or other
conditions that cause interference. 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

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.
225
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Parking Aids

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

Perpendicular Parking
The system detects available
perpendicular 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 perpendicular parking space. Press the button twice to search
for a parking space. When the vehicle speed is less than 19 mph
(30 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

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 perpendicular 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
detected parking space. For example, if your
vehicle detects multiple spaces when you
are driving, it offers the last one.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not tow during the first 1,000 mi
(1,600 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed when towing may reduce
this tendency. •
If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant if the axle is not already
filled with it. See
Capacities and
Specifications (page 380).
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a slope. However, if
you must park on a slope:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in size,
tread-type, or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire
label or Safety Compliance label for
limitations when using these tires.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
