FORD EXPEDITION 2019 Owners Manual

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 Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle. 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
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active. Switching the System Off The switch for the stability and traction
control system is on the instrument panel.
When you switch the system off, a
message and an illuminated icon appear
on the instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See
Principle of
Operation (page 64).

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.

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.

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 64).
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 113).
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 125).
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.

REAR PARKING AID (IF EQUIPPED)
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
12 in (30 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again. Coverage area of up to
6 ft (1.8 m) from
the rear bumper. There may be decreased
coverage area at the outer corners of the
bumper. The system detects certain objects while
the transmission is in reverse (R):
•
Your vehicle is moving toward a
stationary object at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is moving at a speed of
less than 3 mph (5 km/h) and a moving
object is approaching the rear of your
vehicle at a speed of less than
3 mph
(5 km/h).
The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary and the detected
obstacle is less than
12 in (30 cm) away
from the bumper.
Obstacle Distance Indicator
(If
Equipped)
The system provides obstacle distance
indication through the information display.
The distance indicator displays when the
transmission is in reverse (R).
The indicator displays:
• As the distance to the obstacle
decreases the indicator blocks
illuminate and move towards the
vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks are greyed
out.
FRONT PARKING AID (IF EQUIPPED)
The front sensors are active when the
transmission is in any position other than
park (P) and your vehicle is traveling at low
speed.
226

Coverage area of up to 28 in (70 cm) from
the front bumper. The coverage area
decreases at the outer corners.
When your vehicle approaches an object,
a warning tone sounds. When your vehicle
moves closer to an object, the warning
tone repeat rate increases. The warning
tone sounds continuously when an object
is
12 in (30 cm) or less from the front
bumper.
You can switch the system off through the

Obstacle Distance Indicator
(If
Equipped)
The system provides obstacle distance
indication through the information display.
The indicator displays:
• As the distance to the obstacle
decreases the indicator blocks
illuminate and move towards the
vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks turn grey. If the transmission is in reverse (R), the
front sensing system provides audio
warnings when your vehicle is moving and
the detected obstacle is moving towards
your vehicle. Once the vehicle is stationary,
the audio warning stops after two seconds.
Visual indication is always present in
reverse (R).
If the transmission is in drive (D) or any
other forward gear (for example, low (L),
sport (S) or any forward gear in a manual
transmission), the front sensing system
provides audio and visual warnings when
your vehicle is moving below a speed of
5 mph (8 km/h)
and an obstacle is inside
the detection area. Once the vehicle is
stationary, the audio warning stops after
two seconds and the visual indication
stops after four seconds. If the obstacles
detected are within
12 in (30 cm), the
visual indication remains on.
If the transmission is in neutral (N), the
system provides visual indication only
when your vehicle is moving at
5 mph
(8 km/h) or below and an obstacle is
inside the detection area. Once your vehicle
is stationary, the visual indication stops
after four seconds.
SIDE SENSING SYSTEM
(IF
EQUIPPED)
The side sensing system uses the front and
rear side sensors to detect and map
obstacles within the vehicle's driving path,
located near the sides of your vehicle. The
side sensors are active when the
transmission is in any position other than
park (P).
Note: Obstacles that enter the side
detection area without being detected and
mapped by the front or rear side sensors will
not be detected.
