USING HILL DESCENT
CONTROL
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,
the parking brake must be applied or the
vehicle must be placed in
P (Park) or it
may roll away.
Hill descent control allows the driver 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 3 mph
(5 km/h)
and 20 mph (32 km/h). Above
20 mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
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 chime
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 located in the
center of the terrain
management control. A light in the control
illuminates and a chime sounds when this
feature activates.
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 below
20 mph (32 km/h):
When you press the Hill Descent
Control and Hill Descent Control
activates, HILL DESCENT CONTROL
ACTIVE
appears in the message
center for several seconds.
• At speeds below
20 mph (32 km/h):
When you press the Hill Descent
Control switch and conditions are not
correct for hill descent activation, the
Hill Descent Control system enables,
the light on the button is solid and HILL
DESCENT CONTROL READY
displays in the message center for
several seconds.

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: If your vehicle is equipped with
MyKey ™, the sensing system cannot be
turned off when a MyKey ™ is present.
See
Principle of Operation (page 59).
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 alerts. Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts. 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. Remove the add-on device
to prevent false alerts.
Note: When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected to prevent the alert.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
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 105).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 119).
REAR PARKING AID
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.
205
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201711, Fourth-Printing Parking Aids

Obstacle Distance Indicator (If
Equipped) The system provides obstacle distance
indication through the information display.
As the distance to the obstacle decreases,
the indicator blocks illuminate and move
toward the vehicle icon. If there is no
obstacle detected, the distance indicator
blocks show greyed out.
When you shift to reverse (R), the side
sensing system provides audible warnings
when your vehicle is moving and obstacles
are detected within 24 in (60 cm) and are
inside the driving path of your vehicle.
When you stop your vehicle the audible
warning stops after two seconds.
Note:
Visual distance indication remains
on when the transmission is in reverse (R).
When you shift to drive (D) or any other
forward gear, for example, low (L), sport
(S) or any forward gear in manual
transmission, the side sensing system
provides audible and visual distance
warnings when your vehicle is moving
below a speed of
5 mph (8 km/h) and obstacles are detected within
24 in
(60 cm) and are inside the driving path of
your vehicle. Once your vehicle reaches a
standstill condition, the audible warning
stops after two seconds and visual
indication stops after four seconds.
If the transmission is in neutral (N), the side
sensing system provides visual distance
indication only when your vehicle is moving
below a speed of
5 mph (8 km/h) and
there is a front or rear parking aid obstacle
detected, and the side obstacle is within
24 in (60 cm) from the side of your vehicle.
When you stop your vehicle the visual
distance indication stops after four
seconds.
If the side sensing system is not available,
the side distance indicator blocks do not
appear.
The side sensing system is not available
under the following condition:
• If you switch the traction control
system off.
The side sensing system may not be
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

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, for
example motorcycle exhausts, truck air
brakes or horns.
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.

Trailer Brakes
WARNING: Do not connect a trailer's
hydraulic brake system directly to your
vehicle's brake system. Your vehicle may
not have enough braking power and your
chances of having a collision greatly
increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems are
required for safe control of towed vehicles
and trailers weighing more than 1,500 lb
(680 kg) when loaded.
Trailer Lamps WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp
wiring; this may damage the electrical
system resulting in fire. Contact your
authorized dealer as soon as possible for
assistance in proper trailer tow wiring
installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working. 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 drive faster than
70 mph
(113 km/h) during the first 500 mi
(800 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
gearshift 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
grades.
• 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.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
253
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201711, Fourth-Printing Towing

2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
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.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required. TOWING THE VEHICLE ON
FOUR WHEELS - 2.3L
ECOBOOST™
Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in position
N. If
you cannot move the transmission into
N
, you may need to override it. See
Transmission (page 187).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km). WARNING:
If your vehicle has a
steering wheel lock make sure the ignition
is in the accessory or on position when
being towed.
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering the vehicle. See
Climate Control
(page 133).
Follow these guidelines if you have a need
for recreational (RV) towing. An example
of recreational towing would be towing
your vehicle behind a motorhome. We
designed these guidelines to prevent
damage to your transmission.
