2018 FORD EXPLORER parking brake

reinstall the repaired or replaced road tire
as soon as possible. Major dissimilar tire
sizes between the front and rear axles
could cause the 4WD system to stop
functioning and default to front-wheel
drive or damage the 4WD system.
How Your Vehicle Differs From
Other Vehicles
Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving In Special Conditions With
Four-Wheel Drive (4WD)
Note:
4WD vehicles are equipped for driving
on sand, snow, mud and rough roads and
have operating characteristics that are
somewhat different from conventional
vehicles, both on and off the highway. Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
If Your Vehicle Goes Off the Edge of the
Pavement
• If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors,
with minor damage to your vehicle
rather than attempt a sudden return to
the pavement which could cause the
vehicle to slide sideways out of control
or rollover. Remember, your safety and
the safety of others should be your
primary concern.
If Your Vehicle Gets Stuck WARNING: Always set the parking
brake fully and make sure the transmission
is in P (Park). Turn the ignition to the lock
position or turn the vehicle off using the
start/stop button and remove the key
whenever you leave your vehicle.

(If Equipped)

WARNING: If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. See your authorized
dealer. WARNING:
Do not spin the wheels
at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the
transmission and tires may occur or the
engine may overheat.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability
Control ™, it may be beneficial to
disengage the AdvanceTrac® with Roll
Stability Control ™ system while
attempting to rock the vehicle.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid
"over-driving" your vehicle (i.e., turn the
steering wheel only as rapidly and as
far as required to avoid the
emergency). Excessive steering will
result in less vehicle control, not more.
Additionally, smooth variations of the
accelerator and/or brake pedal
pressure should be utilized if changes
in vehicle speed are called for. Avoid abrupt steering, acceleration or braking
which could result in an increased risk
of loss of vehicle control, vehicle
rollover and/or personal injury. Use all
available road surface to return the
vehicle to a safe direction of travel.
• In the event of an emergency stop,
avoid skidding the tires and do not
attempt any sharp steering wheel
movements.
• If the vehicle goes from one type of
surface to another (i.e., from concrete
to gravel) there will be a change in the
way the vehicle responds to a
maneuver (steering, acceleration or
braking). Again, avoid these abrupt
inputs.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Avoid excessive speed because vehicle
momentum can work against you and
cause the vehicle to become stuck to the
point that assistance may be required from
another vehicle. Remember, you may be
able to back out the way you came if you
proceed with caution.
Mud and Water
Note: Driving through deep water may
damage your vehicle.
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the hubs (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle may stall.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 314).
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop. See
Warning Lamps and
Indicators (page 100).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
If it illuminates when you are
driving, this indicates a
malfunction. Your vehicle
continues to have normal braking without
the anti-lock brake system function. Have
your vehicle checked as soon as possible.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer. It illuminates when you engage
the parking brake and the
ignition is on.
If it illuminates when your vehicle is
moving, make sure the parking brake is
disengaged. If the parking brake is
disengaged, this indicates low brake fluid
level or a brake system fault. Have your
vehicle immediately checked.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer.

HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
PARKING BRAKE WARNING: Always set the parking
brake fully and make sure the transmission
is locked in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury.
To set the parking brake, press the parking
brake pedal down to its fullest extent. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release the parking brake, press the
parking brake pedal down again.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNING:
The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. 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 system will turn off
if a malfunction is apparent or if you rev
the engine excessively. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
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.

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
onscreen instructions until the parking
maneuver is complete.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel, or by taking full control of
your vehicle after pressing the active park
assist button.
Keep your hands, hair, clothing and any
loose items clear of the steering wheel
when using active park assist.
The sensors are on the front and rear
bumpers. Note:
Keep the sensors free from snow, ice
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, 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.
