HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to adjust
the speed of your vehicle to maintain a set
gap from the vehicle in front of you in the
same lane while following it to a complete
stop. You can also engage the system to
follow a vehicle in front of you and adjust
set speed while stopped.
WHAT IS ADAPTIVE CRUISE
CONTROL WITH LANE
CENTERING
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the lane by applying
continuous assistance steering torque
input toward the lane center on highways.
Note:
The adaptive cruise control gap
setting operates normally.
WHAT IS INTELLIGENT
ADAPTIVE CRUISE CONTROL
Intelligent adaptive cruise control
combines speed sign recognition with
adaptive cruise control to adjust the cruise
set speed to the speed limit detected by
the speed sign recognition system. For
example, if the speed sign recognition
system detects a 50 mph (80 km/h)
speed limit, the cruise set speed is updated
to
50 mph (80 km/h).
Note: The adaptive cruise control gap
setting operates normally. ADAPTIVE CRUISE CONTROL

WARNING: Pay close attention to
changing road conditions such as
entering or leaving a highway, on roads
with intersections or roundabouts, roads
without visible lanes of travel, roads that
are winding, slippery, unpaved, or steep
slopes. WARNING:
The system does not
control speed in low traction conditions
or extremely steep slopes. 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
personal injury. WARNING:
The system is not a
crash warning or avoidance system. WARNING:
Do not use the system
when towing a trailer that has
aftermarket electronic trailer brake
controls. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
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. WARNING:
Do not use the system
with a snow plow blade installed. WARNING:
Do not use the system
in poor visibility, for example fog, heavy
rain, spray or snow. When Following a Vehicle WARNING:
When following a
vehicle that is braking, your vehicle does
not always decelerate quickly enough to
avoid a crash without driver intervention.
Apply the brakes when necessary. Failure
to follow this instruction could result in
personal injury or death.
Hilly Condition Usage
You should select a lower gear 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 it from overheating.
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 after the brakes cool.

Information (page 114).
• Touchscreen. See Settings (page 464).
When you switch the system off, a warning
lamp illuminates and the alert indicators
flash twice.
Note: The system remembers the last
setting when you start your vehicle.
Note: The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
To permanently switch the system off,
contact an authorized dealer.
Blind Spot Information System
with Trailer Tow
(If Equipped) The design of the system is to aid you in
detecting vehicles that could have entered
the detection area zone (A). The detection
area is on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
When you attach and have setup a trailer,
the blind spot information system with
trailer tow becomes active when driving
forward above
6 mph (10 km/h). You can switch the system off in the
information display.
See General
Information (page 114). If you switch the
blind spot information system off, blind
spot information system with trailer tow
turns off.
Setting up a Trailer
You can setup a trailer through the
information display.
See General
Information (page 114). Trailer length.
A
Trailer width.
B
Trailer hitch ball.
C
Note: Measure the width of the trailer at
the front of the trailer, not the widest point.
The maximum width that the system can
support is
8.2 ft (2.5 m)(B).
Note: The trailer length is the distance
between the trailer hitch ball and the rear
of the trailer. The maximum length that the
system can support is
33 ft (10 m)(A).
When setting up a trailer, a sequence of
screens appear asking for trailer
information:
• Select trailer screen: None, Trailer A,
Trailer B or Trailer C.
Note: You can select only one trailer on
small information displays.
Select one of the trailers and press OK. The
menu goes to the next screen.
• Width less than
8.2 ft (2.5 m) and
length less than 33 ft (10 m)?
266
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Driving AidsE293525 E293526

Note:
You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer is
8.2 ft (2.5 m) or less.
If no, the system turns off.
If yes, the menu goes to the next screen.
• Enter length of trailer:
Toggling up or down using the menu
buttons increases or decreases the
measurement by
3 ft (1 m). Select a length
that is equal to or within 3 ft (1 m) of the
actual measured length. For example, if
the actual measured length is 25 ft (7.6 m),
toggle the length in the menu to 8 m or 27
ft. When you enter the length of the trailer,
this saves the system setup.
Note: When you connect a trailer, but do
not setup a trailer in the blind spot
information system, the system turns off
and a warning appears in the information
display.
Note: If the trailer is a bike rack or cargo
rack with electrical lighting, enter a length
of
3 ft (1 m). Cross Traffic Alert remains on
for trailers with a length of 3 ft (1 m) or less.
Note: The system requires proper
measurement and measurement entry to
function as designed.
System Operation
If you select a trailer in the information
display prior to connecting a trailer, the
system loads that configuration and the
information display shows a message
when you connect the trailer. A second
message appears stating cross traffic alert
is off, unless a trailer is set up with a length
of
3 ft (1 m). The blind spot information
system with trailer tow still functions
normally when driving forward. If you connect a trailer, a message appears
indicating that you attached a trailer. If you
have not selected a trailer previously,
another message appears requesting you
to select one of the trailers in the list or add
a new trailer. The blind spot information
system with trailer tow does not function
without a trailer selected. If you do not
select a trailer, a message appears in the
information display stating it has
deactivated the system. This message
might not appear until your vehicle speed
reaches
22 mph (35 km/h).
The blind spot information system with
trailer tow activates when driving forward
for that particular trailer set up. If you cycle
the ignition, the blind spot information
system with trailer tow continues to
function using the last trailer you selected.
Trailer Considerations
The system works with a trailer with a front
width of
8.2 ft (2.5 m) or less, and a total
length from the trailer hitch ball to the rear
of the trailer of
33 ft (10 m) or less.
Some trailers could cause a slight change
in system performance:
• Wide box trailers, especially those
wider than the towing vehicle, could
cause false alerts to occur when driving
next to infrastructure or near parked
cars. A false alert could also occur
while making a 90-degree turn or
driving through a roundabout.
• Wide trailers that have a total length
greater than
20 ft (6 m) could cause
delayed alerts when a vehicle is
passing at high speeds.
267
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Driving Aids

•
Box trailers that have a width greater
than 8.2 ft (2.5 m) could cause early
alerts when you pass a vehicle.
• Clam shell or V-Nose box trailers with
a width greater than
8.2 ft (2.5 m)
could cause delayed alerts when a
vehicle traveling the same speed as
your vehicle merges lanes.
System Errors
If the system detects a fault, a warning
lamp illuminates and a message displays.
See
Information Messages (page 121).
Switching the System On and Off
You can switch the blind spot information
system with trailer tow off by not selecting
a trailer the information display.
See
General Information (page 114). In this
case, the system turns off as long as a
trailer is attached to your vehicle. As soon
as you disconnect the trailer, the blind spot
information system becomes active.
When you switch the system off, a warning
lamp illuminates and the alert indicators
flash twice.
Note: The system remembers the last
trailer setting when you start your vehicle.
You cannot switch off the blind spot
information system with trailer tow when
using MyKey, but you can still change the
trailer settings.
See MyKey ™ (page 64).
To permanently switch the system off,
contact an authorized dealer. CROSS TRAFFIC ALERT WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The
cross traffic alert system is not a
replacement for careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash.
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Slowly reversing helps
increase the coverage area and
effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of
reverse (R).
268
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Driving Aids

Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Cross Traffic Alert System Sensors
The sensors are behind the rear bumper
on both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Blocked sensors could affect system
performance.
If the sensors are blocked, a message may
appear in the information display when
you shift into reverse (R).
Cross Traffic Alert System
Limitations
The system may not correctly operate
when any of the following occur:
• The sensors are blocked.
• Adjacently parked vehicles or objects
are obstructing the sensors.
• Vehicles approach at speeds less than
4 mph (6 km/h) or greater than 37 mph
(60 km/h).
• The vehicle speed is greater than 7 mph
(12 km/h)
.
• You reverse out of an angled parking
space. Cross Traffic Alert Behavior When
Trailer is Attached
Note:
The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
Cross traffic alert remains on when you
attach a trailer in vehicles that come with
blind spot information system with trailer
tow under the following conditions:
• You connect a trailer.
• The trailer is a bike rack or cargo rack
with a maximum length of
3 ft (1 m).
• You set the trailer length to
3 ft (1 m)
in the information display.
See
Blind Spot Information System
(page 264).
Switching the System On and Off
To switch the system on or off, adjust the
setting. Depending on your vehicle options,
the setting could be in the following:
• Information display.
See General
Information (page 117).
• Touchscreen. See Settings (page 464).
Note: The system turns on every time you
switch the ignition on. To permanently
switch the system off, contact an authorized
dealer.
Cross Traffic Alert Indicator When the system detects an
approaching vehicle, a tone
sounds, a warning lamp
illuminates in the relevant exterior mirror
and arrows appear in the information
display to show which side the
approaching vehicle is coming from.

Note:
Using deep snow/sand mode on dry,
hard surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.
Eco For efficient driving. This mode
helps deliver maximum fuel
efficiency and helps to increase
driving range.
Normal For everyday driving. This mode
is a perfect balance of
excitement, comfort and
convenience. This is the default mode after
each ignition cycle.
Slippery For less than ideal road
conditions, such as snow or ice
covered roads. Use this mode for
crossing terrain with a firm surface covered
with loose, wet or slippery material.
Slippery mode lowers throttle response
and, if provided with an automatic
transmission, optimizes shifting for slippery
surfaces.
Note: Using slippery mode on dry, hard
surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery surfaces. Sport For sporty driving with improved
performance handling, and
response. This mode increases
throttle response and provides a sportier
steering feel. If equipped with automatic
transmission, the powertrain system
provides improved gear holding, helping
your vehicle accelerate faster.
Tow/Haul For improved transmission
operation when towing a trailer
or a heavy load. This mode
moves upshifts to higher engine speeds to
reduce the frequency of transmission
shifting. This mode also provide engine
braking in all forward gears, which slows
your vehicle and assists you in controlling
your vehicle when descending a grade. The
amount of downshift braking provided
varies based on the amount you press the
brake pedal.
Trail For muddy, rutted, soft or uneven
terrain.

Tire and Loading Label Information
Example:
Payload
Payload is the combined weight
of cargo and passengers that your
vehicle is carrying. The maximum
payload for your vehicle appears
on the Tire and Loading label. The
label is either on the B-pillar or the
edge of the driver door. Vehicles
exported outside the US and
Canada may not have a tire and
loading label. Look for
“The
combined weight of occupants
and cargo should never exceed
XXX kg OR XXX lb ” for maximum
payload. The payload listed on the
Tire and Loading Information label is the maximum payload for your
vehicle as built by the assembly
plant. If you install any additional
equipment on your vehicle, you
must determine the new payload.
Subtract the weight of the
equipment from the payload listed
on the Tire and Loading label.
When towing, trailer tongue
weight or king pin weight is also
part of payload.
WARNING: The
appropriate loading capacity of
your vehicle can be limited either
by volume capacity (how much
space is available) or by payload
capacity (how much weight the
vehicle should carry). Once you
have reached the maximum
payload of your vehicle, do not
add more cargo, even if there is
space available. Overloading or
improperly loading your vehicle
can contribute to loss of vehicle
control and vehicle rollover.
GAWR (Gross Axle Weight
Rating)
GAWR is the maximum allowable
weight that a single axle (front or
rear) can carry. These numbers
are on the Safety Compliance
Certification label. The label is
located on the door hinge pillar,
door-latch post, or the door edge
that meets the door-latch post,
next to the driver seating position.
