2017 FORD EXPLORER warning

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
When you switch the system off or on, a
message appears in the information
display showing system status.
You can switch the system off by either
using the information display controls or
the switch. Using the Information Display
Controls
You can switch this feature off or on in the
information display. See General
Information (page 99).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off
or on.
System Indicator Lights and
Messages The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you switch the traction control
system off.

PRINCIPLE OF OPERATION
WARNINGS
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. 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 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 systems
applies higher brake forces.
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.
Curve Control
The system enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one
or more of the wheels individually.

USING HILL DESCENT
CONTROL
Principle of operation
WARNINGS
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. 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
WARNINGS
To help avoid personal injury, please
read and understand the limitations
of the system as contained in this
section. Sensing is only an aid for some
(generally large and fixed) objects when
moving on a flat surface at parking speeds.
Certain objects with surfaces that absorb
ultrasonic waves, surrounding vehicle's
parking aid systems, traffic control
systems, fluorescent lamps, inclement
weather, air brakes, and external motors
and fans may also affect the function of
the sensing system; this may include
reduced performance or a false activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
This system is not designed to
prevent contact with small or moving
objects. The system is designed to
provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging your vehicle. The system may
not detect smaller objects, particularly
those close to the ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the
normal detection zone of the system, may
create false beeps. 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. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 55).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear sensing
system may detect that add-on device and
therefore provide warnings. It is suggested
that you disable the rear sensing system
when you attach an add-on device to your
vehicle to prevent these warnings.
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. 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 99).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 113).
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.
195
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Parking AidsE139213

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 grayed
out.
FRONT PARKING AID
(If Equipped)
The front sensors are active when the
transmission is in any position other than
park (P) or neutral (N) and the vehicle
speed is below
6 mph (10 km/h). 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.
196

• If there is no obstacle detected, the
distance indicator blocks are grayed
out.
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 will be stopped after 2
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
7 mph (12 km/h) and an obstacle is located
inside the detection area. Once the vehicle
is stationary, the audio warning will be
stopped after 2 seconds and the visual
indication stops after 4 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
7 mph
(12 km/h) or below and an obstacle is
located inside the detection area. Once
your vehicle is stationary, the visual
indication will stop after 4 seconds.
SIDE SENSING SYSTEM
(If
Equipped)
The side sensing system uses the front and
rear side sensors to detect and map
obstacles that are near to 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. Coverage area is up to 24 in (60 cm) from
the sides of your vehicle.
As your vehicle moves closer to the
obstacle, the rate of the audible warning
increases. The rate of the audible warning
varies depending on whether the obstacle
is inside or outside the driving path of your
vehicle.
197
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Parking AidsE187810

Additionally, the system provides obstacle
distance indication through the center
stack display (if equipped).
•
As the distance to the obstacle
decreases (obstacle becomes closer),
the indicator blocks illuminate and
move towards the vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks show grayed
out.
Obstacle Distance Indicator (If
Equipped) When you shift to reverse (R), the side
sensing system provides audible warnings
when your vehicle is moving and obstacles
are detected within
12 in (30 cm) or when
obstacles are detected within 12 –24 in
(30–60 cm) and are inside the driving path
of your vehicle. Once your vehicle reaches
a standstill condition, the audible warning
stops after 2 seconds. Visual indication is
always present 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 warnings when
your vehicle is moving below a speed of
7 mph (12 km/h)
and obstacles are
detected within 12 in (30 cm) or when
obstacles are detected within 12 –24 in
(30–60 cm) and are inside the driving path
of your vehicle. Once your vehicle reaches
a standstill condition, the audible warning
stops after 2 seconds and visual indication
stops after 4 seconds. If the obstacles
detected are within
12 in (30 cm), the
visual indication remains on.
If the transmission is in neutral (N), the side
sensing system provides visual indication
(not audible) only when your vehicle is
moving below a speed of 7 mph (12 km/h)
and obstacles are detected within
12 in
(30 cm). Once your vehicle reaches a
standstill condition, the visual indication
stops after 4 seconds.
If the side sensing system is not available,
the side distance indicator blocks will not
be present.

ACTIVE PARK ASSIST (If Equipped)
Parallel Parking, Perpendicular
Parking, Parallel Park Out Assist
WARNINGS
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. The sensors may not detect objects
in heavy rain or other conditions that
cause interference.
Active park assist does not apply the
brakes under any circumstances.
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. The system detects an available parallel
or perpendicular parking space and
automatically steers your vehicle into the
space (hands-free) while you control the
accelerator, gearshift and brakes. The
system visually and audibly guides you to
park your vehicle.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system.
Parallel Park Out Assist 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. Note:
The Blind Spot Information System
does not detect traffic alongside or behind
your vehicle during a park assist maneuver.
The system may not correctly operate in
any of the following conditions:
• You use a spare tire or a tire
significantly worn more than the other
tires.
• One or more tires are improperly
inflated.
• You try to park on a tight curve.
• Something passes between the front
bumper and the parking space (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
(heavy rain, snow, fog, etc).
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. Covered sensors
can affect the system's accuracy. Do not
clean the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves
or cause ultrasonic interference (motorcycle
exhaust, truck air brakes or horns).
Do not use the system if:
• You have attached a bike rack, trailer
or other object near the sensors on the
front or rear of your vehicle.
• You have attached an overhanging
object (surfboard) to the roof.
• A foreign object damages or obstructs
the front or rear bumper or side
sensors.
• The correct tire size is not in use on your
vehicle (for example, a mini-spare tire).
