ABOUT THIS MANUAL
Thank you for choosing Ford. We
recommend that you take some time to
get to know your vehicle by reading this
manual. The more that you know about
your vehicle, the greater the safety and
pleasure you will get from driving it.
WARNING: Driving while
distracted can result in loss of vehicle
control, crash and injury. We strongly
recommend that you use extreme
caution when using any device that may
take your focus off the road. Your
primary responsibility is the safe
operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving.
Note: This manual describes product
features and options available throughout
the range of available models, sometimes
even before they are generally available. It
may describe options not fitted to the
vehicle you have purchased.
Note: Some of the illustrations in this
manual may show features as used in
different models, so may appear different
to you on your vehicle.
Note: Always use and operate your vehicle
in line with all applicable laws and
regulations.
Note: Pass on this manual when selling
your vehicle. It is an integral part of your
vehicle.
This manual may qualify the location of a

WARNING: Do not connect
wireless plug-in devices to the data link
connector. Unauthorized third parties
could gain access to vehicle data and
impair the performance of safety related
systems. Only allow repair facilities that
follow our service and repair instructions
to connect their equipment to the data
link connector.
We respect your privacy and are
committed to protecting it. The
information contained in this manual was
correct at the time of publication, but as
technology rapidly changes, we
recommend that you visit the local Ford
website for the latest information.
Your vehicle has electronic control units
that have data recording functionality and
the ability to permanently or temporarily
store data. This data could include
information on the condition and status of
your vehicle, vehicle maintenance
requirements, events and malfunctions.
The types of data that can be recorded are
described in this section. Some of the data
recorded is stored in event logs or error
logs.
Note: Error logs are reset following a service
or repair.
Note: We may provide information in
response to requests from law enforcement,
other government authorities and third
parties acting with lawful authority or
through a legal process. Such information
could be used by them in legal proceedings.
Data recorded includes, for example:
• Operating states of system
components, for example fuel level,
tire pressure and battery charge level.
• Vehicle and component status, for
example wheel speed, deceleration,
lateral acceleration and seatbelt
status. •
Events or errors in essential systems,
for example headlamps and brakes.
• System responses to driving situations,
for example airbag deployment and
stability control.
• Environmental conditions, for example
temperature.
Some of this data, when used in
combination with other information, for
example an accident report, damage to a
vehicle or eyewitness statements, could
be associated with a specific person.
Services That We Provide
If you use our services, we collect and use
data, for example account information,
vehicle location and driving characteristics,
that could identify you. We transmit this
data through a dedicated, protected
connection. We only collect and use data
to enable your use of our services to which
you have subscribed, with your consent or
where permitted by law. For additional
information, see the terms and conditions
of the services to which you have
subscribed.
For additional information about our
privacy policy, refer to the local Ford
website.
Services That Third Parties
Provide
We recommend that you review the terms
and conditions and data privacy
information for any services equipped with
your vehicle or to which you subscribe. We
take no responsibility for services that third
parties provide.

GENERAL INFORMATION ON
RADIO FREQUENCIES
This device complies with Part 15 of the
FCC Rules and with Industry Canada
license-exempt RSS standard(s).
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) This device
must accept any interference received,
including interference that may cause
undesired operation.
WARNING: Changes or
modifications not expressively approved
by the party responsible for compliance
could void the user's authority to operate
the equipment. The term "IC:" before the
radio certification number only signifies
that Industry Canada technical
specifications were met.
The typical operating range for your
transmitter is approximately
33 ft (10 m).
Vehicles with the remote start feature will
have a greater range.
One of the following could cause a
decrease in operating range:
• Weather conditions.
• Nearby radio towers.
• Structures around the vehicle.
• Other vehicles parked next to your
vehicle.
The radio frequency used by your remote
control can also be used by other radio
transmitters, for example amateur radios,
medical equipment, wireless headphones,
wireless remote controls, cell phones,
battery chargers and alarm systems. If the
frequencies are jammed, you will not be
able to use your remote control. You can
lock and unlock the doors with the key.
Note: Make sure to lock your vehicle before
leaving it unattended. Note:
If you are in range, the remote control
will operate if you press any button
unintentionally.
Note: The remote control contains sensitive
electrical components. Exposure to moisture
or impact may cause permanent damage.
Intelligent Access
(If Equipped)
The system uses a radio frequency signal
to communicate with your vehicle and
authorize your vehicle to unlock when one
of the following conditions are met:
• You activate the front exterior door
handle switch.
• You press the luggage compartment
button.
• You press a button on the transmitter.
If excessive radio frequency interference
is present in the area or if the transmitter
battery is low, you may need to
mechanically unlock your door. You can
use the mechanical key blade in your
intelligent access key to open the driver
door in this situation. See
Remote
Control (page 57).
REMOTE CONTROL
Integrated Keyhead Transmitter
Use the key blade to start your vehicle and
unlock or lock the driver door from outside
your vehicle. The integrated keyhead
transmitter functions as a programmed
ignition key that operates all the locks and
starts your vehicle, as well as a remote
control.
57
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Keys and Remote Controls

Press the release button and pull the key
blade out.
Note:
Your vehicle keys came with a
security label that provides important key
cut information. Keep the label in a safe
place for future reference.
Replacing the Battery
Note: Refer to local regulations when
disposing of transmitter batteries.
Note: Do not wipe off any grease on the
battery terminals or on the back surface of
the circuit board.
Note: Replacing the battery does not erase
the programmed key from your vehicle. Your
remote control should operate normally. A message appears in the information
display when the remote control battery
is low. See Information Messages (page
121).
Integrated Keyhead Transmitter
The remote control uses one coin-type
three-volt lithium battery.

before beginning the procedure. 1. Insert a suitable tool, for example a
screwdriver, in the position shown and
gently push the clip.

Memory Feature (If Equipped)
You can use the remote control to recall
memory positions.
If programmed to a pre-set position, the
remote control recalls memory positions
when you unlock your vehicle. If you have
the easy entry and exit feature enabled
and the ignition is off, the seat moves to
the easy entry position. The seat moves
to the driver memory position when you
switch the ignition on.
