brake FORD EXPLORER 2017 5.G Service Manual

The system determines the clearance to
the front and rear of your vehicle and
automatically steers your vehicle out of a
parallel parking space (hands-free) while
you control the accelerator, gearshift and
brakes. The system visually and audibly
guides you to enter traffic.
After the system has directed your vehicle
past the adjacent vehicle or object, it
guides you to take control of the steering
to complete the exit from the parking spot.
Note:
If the clearance in front of your
vehicle allows easy departure, the Parallel
Park Out Assist feature might not be
available.
Note: You are responsible for controlling
your vehicle and making sure the path is
clear prior to pulling into traffic.
Note: This system is not intended to assist
in exiting perpendicular parking spaces,
damages to your vehicle may occur.
Note: If your vehicle speed exceeds 3 mph
(5 km/h) or the maneuver is interrupted
(driver input), the system switches off and
you need to take full control of your vehicle. Deactivating the Active Park
Assist Feature
Manually deactivate the system by:
•
Pressing the active park assist button
during an active maneuver.
• Grabbing the steering wheel during an
active maneuver.
• Driving above approximately
22 mph
(35 km/h) for 30 seconds during an
active park search.
• Driving above approximately
6 mph
(10 km/h) during automatic steering.
• Switching off the traction control
system.
Certain vehicle conditions can also
deactivate the system, such as:
• Traction control has activated.
• There is an anti-lock brake system
activation or failure.
If a problem occurs with the system, a
warning message displays accompanied
by a tone. Occasional system messages
may occur in normal operation. For
recurring or frequent system faults, contact
an authorized dealer to have your vehicle
serviced.
Troubleshooting the System The system does not look for a space
The traction control system may be off.
The transmission is in reverse (R). Your vehicle must be moving forward to be able to
detect a parking space.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL WARNINGS
Do not use cruise control on winding
roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed may increase above
the set speed. The system will not
apply the brakes but a warning displays. The cruise controls are on the steering
wheel.
Switching Cruise Control On

USING ADAPTIVE CRUISE
CONTROL
(If Equipped) WARNINGS
Always pay close attention to
changing road conditions when using
adaptive cruise control. The system
does not replace attentive driving. Failing
to pay attention to the road may result in
a crash, serious injury or death. Adaptive cruise control is not a crash
warning or avoidance system.
Adaptive cruise control does not
detect stationary or slow moving
vehicles below
6 mph (10 km/h).
Adaptive cruise control does not
detect pedestrians or objects in the
road.
Adaptive cruise control does not
detect oncoming vehicles in the
same lane.
Do not use adaptive cruise control
on winding roads, in heavy traffic or
when the road surface is slippery.
This could result in loss of vehicle control,
serious injury or death. Do not use adaptive cruise control
when towing a trailer that has trailer
brakes. The auto-brake component
of the adaptive cruise control system does
not operate the trailer brakes. Using
adaptive cruise control when towing a
trailer that has trailer brakes may result in
the loss of vehicle control, which could
result in serious injury. WARNINGS
Do not use tire sizes other than those
recommended because this can
affect the normal operation of the
system. Failure to do so may result in a loss
of vehicle control, which could result in
serious injury. The system adjusts your vehicle speed to
maintain the set gap between you and the
vehicle in front of you in the same lane.
The adaptive cruise controls are on the
steering wheel.
Switching Adaptive Cruise Control
On
Press and release
ON.
The indicator appears in the
information display.
The current gap setting and
SET will also
appear.

Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Cruise ControlE200996 E144529 E164805

Setting the Adaptive Cruise Speed
1. Drive to desired speed.
2. Press and release SET+.
3. A green indicator light, the current gap
setting and your set speed appear in
the information display.
4. Take your foot off the accelerator pedal. 5. A vehicle graphic illuminates if there is
a vehicle detected in front of you.
Note: When adaptive cruise control is
active, the speedometer may vary slightly
from the set speed displayed in the
information display.
Following a Vehicle WARNINGS
When following a vehicle, your
vehicle does not decelerate
automatically to a stop, nor does
your vehicle always decelerate quickly
enough to avoid a crash without driver
intervention. Always apply the brakes when
necessary. Failing to do so may result in a
crash, serious injury or death. Adaptive cruise control only warns
of vehicles detected by the radar
sensor. In some cases there may be
no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in a
crash, serious injury or death. Note:
The brakes may emit noise when
applied by the system.
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 will maintain 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 brake lamps
automatically turn on when the system
applies the brakes. The maximum braking
which the system applies is limited. You
can override the system by applying the
brakes.
If the system determines that its maximum
braking level will not be sufficient, an
audible warning sounds while the system
continues to brake. A red warning bar
displays on the windshield and you must
take immediate action.
Note: When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small
temporary acceleration to help you pass.
Setting the Gap Distance
You can decrease or increase the gap
between your vehicle and the vehicle in
front of you by pressing the gap control.
You can select five gap settings.
Note: It is your responsibility to select a gap
appropriate to the driving conditions.

information display while the system is
active.
Resuming the Set Speed
Press and release RES. The vehicle returns
to the previously set speed and gap setting.
The set speed displays continuously in the
information display while 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 does not operate below
12 mph (20 km/h)
. An audible warning
sounds and the automatic braking releases
if the vehicle drops below this speed. Hilly Condition Usage
You should select a lower gear position
when the system is active in situations
such as prolonged downhill driving on
steep grades, for example in mountainous
areas. The system needs additional engine
braking in these situations to reduce the
load on the vehicle
’s regular brake system
to prevent them from overheating.
Note: An audible warning sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool down. The system functions
normally again when the brakes have cooled
down.
Switching Adaptive Cruise Control
Off
Press and release the
OFF button when
the system is in stand by mode or switch
the ignition off.
Note: The set speed memory erases when
you switch off the system.
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. The radar sensor has a limited field of
vision. 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.
213
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Cruise Control

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. The driver should stay
alert and intervene when necessary.
If something hits the front of your vehicle
or damage occurs, the radar-sensing zone
may change. This could cause missed or
false vehicle detections. See an authorized
dealer to have the radar checked for
correct operation.
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 located on the lower grille. The
system cannot detect a vehicle ahead and
does not function when something
obstructs the radar signals.
214
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Cruise ControlE71621 E145632

The following table lists 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 in the grille is dirty
or obstructed in some way.
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 in the grille 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.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Swirling water, or 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 and not
be blocked. This can happen, for example,
when driving in sparse rural environments.
A false blocked condition self clears or
clears after a key cycle.
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. You can manually change from adaptive
cruise control to normal cruise control
through the information display. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles
and automatic braking does not activate.
215
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Cruise ControlE71340

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) WARNINGS
This system is an extra driving aid. It
does not replace your attention and
judgment, or the need to apply the
brakes. This system does NOT
automatically brake your vehicle. If you fail
to press the brake pedal when necessary,
you may collide with another vehicle. The Pre-Collision Assist system with
brake support cannot help prevent
all collisions. Do not rely on this
system to replace your judgment and the
need to maintain correct 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.
Note: The Pre-Collision Assist 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.
227

When your vehicle rapidly approaches
another vehicle, a red warning light flashes
and a 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 increases after the
audio-visual warning, the brake support
prepares the brake system for rapid
braking. The system does not
automatically activate the brakes, but if
the brake pedal is pressed even lightly, the
brakes apply full stopping power.
Using the Pre-Collision Assist
System
WARNING
The Pre-Collision Assist system
’s
brake support reduces collision
speed only if you brake your vehicle
before any collision. As in any typical
braking situation, you must press your
brake pedal. You can adjust the warning system's
sensitivity through your information
display. See General Information (page
99). Note:
When possible, the manufacturer
recommends using the highest sensitivity
setting. If warnings are too frequent, you can
reduce your system's sensitivity. Reduced
sensitivity causes fewer and later system
warnings. See
General Information (page
99).
Blocked Sensors If a blocked sensor message appears in the
information display, dirt, water, or an object
is blocking the sensor. The sensor is
located behind a cover near the driver side
of the lower grille. If anything blocks the
sensor, your vehicle cannot see through
the sensor, and the pre-collision assist
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.
