brake FORD EXPLORER 2019 Workshop Manual

When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance. A
vehicle graphic illuminates in the
instrument cluster.
Your vehicle maintains a consistent gap
from the vehicle ahead until:
•
The vehicle in front of you accelerates
to a speed above the set speed.
• The vehicle in front of you moves out
of the lane you are in.
• Your vehicle speed falls below 12 mph
(20 km/h).
• You set a new gap distance.
The system applies the brakes to slow your
vehicle to maintain a safe gap distance
from the vehicle in front. The system only
applies limited braking. You can override
the system by applying the brakes.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
information display and an indicator
flashes when the system continues to
brake. Take immediate action.
Setting the Gap Distance
You can decrease or increase the distance
between your vehicle and the vehicle in
front by pressing the gap control. Press and release to decrease
the gap distance.
Press and release to increase the
gap distance. The selected gap appears in the
information display as shown by the bars
in the image.
Note:
The gap setting is time dependent
and therefore the distance adjusts with your
vehicle speed.
Note: It is your responsibility to select a gap
appropriate to the driving conditions.

When you press the accelerator pedal, you
override the set speed and gap distance.
Use the accelerator pedal
normally to intentionally exceed
the set speed limit.
When you override the system, the green
indicator light illuminates and the vehicle
image does not appear in the information
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle.
Changing the Set Speed Press and release to increase the
set speed in small increments.
Press and release to decrease
the set speed in small
increments.
Press and hold either button to change the
set speed in large increments. Release the
button when you reach the speed you
prefer.
Press the accelerator or brake pedal until
you reach the speed you prefer. Press
either button.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed Press and release the button or
tap the brake pedal.
The set speed does not erase. Resuming the Set Speed Press and release the button.
Your vehicle speed returns to the
previously set speed and gap setting. The
set speed displays continuously in the
information display when the system is
active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). The
information display indicates low engine
speed, an audible alarm sounds and the
automatic braking releases if the vehicle
drops below this speed.
Automatic cancellation can also occur
when:
• The tires lose traction.
• You apply the parking brake.
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
Hilly Condition Usage
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again when the brakes have
cooled.
Select a lower gear during prolonged
downhill driving on steep slopes, such as
mountainous areas, when the system is
active. In such situations, the system needs
additional engine braking to reduce the
load on the vehicle ’s regular brake system
to prevent the brakes from overheating.

Switching Adaptive Cruise Control
Off
Press and release the button
when the system is in standby
mode, or switch the ignition off.
Note: You erase the set speed and gap
setting when you switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the
road infrastructures, for example bridges,
tunnels and safety barriers. In these
cases, the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening,
if required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you. Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C
In these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary.
If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.

Optimal system performance requires a
clear view of the road by the
windshield-mounted camera.
Optimal performance may not occur if:
•
The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions.
System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
• A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system. Blocked Sensor A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
Note:
You cannot see the sensor. It is
behind a fascia panel.
Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.
Possible Causes and Actions for This Message Displaying: Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar is dirty or
obstructed.
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar is clean but the
message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
223
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201807, Second-Printing Cruise ControlE145632

Action
Cause
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Water, snow or ice on the surface of the
road may interfere with the radar signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. A false blocked condition either self clears, or clears after you restart your
vehicle.
Switching to Normal Cruise
Control WARNING: Normal cruise control
will not brake when your vehicle is
approaching slower vehicles. Always be
aware of which mode you have selected
and apply the brakes when necessary. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, and the system
does not respond to lead vehicles.
Automatic braking remains active to
maintain set speed.
You can change from adaptive cruise
control to normal cruise control through
the information display.

Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems. PRE-COLLISION ASSIST (IF
EQUIPPED) 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. WARNING:
The system does not
detect vehicles that are driving in a
different direction, pedestrians at night,
cyclists or animals. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead
to a crash or personal injury. WARNING:
The system may fail
or operate with reduced function during
cold and severe weather conditions.
Snow, ice, rain, spray and fog can
adversely affect the system. Keep the
front camera and radar free of snow and
ice. Failure to take care may result in the
loss of control of your vehicle, serious
personal injury or death. WARNING: In situations where the
vehicle camera has limited detection
capability, this may reduce system
performance. These situations include
but are not limited to direct or low
sunlight, vehicles at night without tail
lights, unconventional vehicle types,
pedestrians with complex backgrounds,
236
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201807, Second-Printing Driving Aids

running pedestrians, partly obscured
pedestrians, or pedestrians that the
system cannot distinguish from a group.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death.
WARNING: The pre-collision assist
system's brake support reduces collision
speed only if you brake your vehicle
before any collision. You must press your
brake pedal as you would in any typical
braking situation. WARNING: The system cannot
help prevent all crashes. Do not rely on
this system to replace driver judgment
and the need to maintain a safe distance
and speed.
Note: The system does not detect, warn or
respond to potential collisions with vehicles
to the rear or sides of your vehicle.
Using the Pre-Collision Assist
System
The system is active at speeds above
approximately
5 mph (8 km/h). The system alerts you of certain collision
risks. The system's sensor detects your
vehicle's rapid approach to other vehicles
traveling in the same direction as your
vehicle. When your vehicle rapidly approaches
another vehicle, a flashing visual warning
appears and an audible warning tone
sounds.
The brake support system assists you in
reducing any collision speed by
pre-charging the brakes. If the risk of
collision continues to increase after the
audio-visual warning, the brake support
prepares the brake system for rapid
braking. Brake support does not
automatically apply the brakes. If you press
the brake pedal, the system could apply
additional braking up to maximum braking
force, even if you lightly press the brake
pedal.
You can adjust the warning system's
sensitivity through your information
display.
See General Information (page
104).
Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.

vehicle
’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The gross combined weight must
never exceed the Gross Combined
Weight Rating.
Note: For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Do not use
replacement tires with lower
load carrying capacities than the
original tires because they may
lower your vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
original tires do not increase the
GVWR and GAWR limitations. WARNING:
Exceeding any
vehicle weight rating can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death.
Steps for determining the
correct load limit:
1. Locate the statement "The combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle ’s placard.
2. Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3. Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lb.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1,400 lb. and there will
be five 150 lb. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.)

TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Note: See
Recommended
Towing Weights (page 248).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 271).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop and load
capacity. When both the
loaded vehicle and trailer are
connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
241).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

TRAILER SWAY CONTROL (IF
EQUIPPED) WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it when it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if your vehicle speed
is too high, the system may turn on multiple
times, gradually reducing your vehicle speed.
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability. If the trailer
begins to sway, the stability control
warning lamp flashes and a message
appears in the information display. See
Information Messages
(page 115). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
239).
You can switch this feature off in the
information display. When you switch the
ignition on, the system automatically turns
on. RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Be sure to take into
consideration trailer frontal area.
Do not exceed 20 ft² (1.86 m²) if
your vehicle can tow a class I trailer
or 40 ft² (3.72 m²) if your vehicle
can tow a class III trailer.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per
1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as the
vehicle ’s electrical system may not
include the wiring connector
needed to activate electric trailer
brakes.
