System
WARNING: Do not use the system
with any garage door opener that does not
have the safety stop and reverse feature
as required by U.S. Federal Safety
Standards (this includes any garage door
opener manufactured before April 1, 1982).
A garage door opener which cannot detect
an object, signaling the door to stop and
reverse, does not meet current federal
safety standards. Using a garage door
opener without these features increases
the risk of serious injury or death.
Note: Make sure that the garage door and
security device are free from obstruction
when you are programming. Do not program
the system with the vehicle in the garage.
Note: Make sure you keep the original
remote control transmitter for use in other
vehicles as well as for future system
programming.
Note: We recommend that upon the sale
or lease termination of your vehicle, you
erase the programmed function buttons for
security reasons. See Erasing the Function
Button Codes
.
Note: You can program a maximum of
three devices. To change or replace any of
the three devices after it has been initially
programmed, you must first erase the
current settings. See Erasing the Function
Button Codes
. The universal garage door opener replaces
the common hand-held garage door
opener with a three-button transmitter
that is integrated into the driver
’s sun visor.
The system includes two primary features,
a garage door opener and a platform for
remote activation of devices within the
home. As well as being programmed for
garage doors, the system transmitter can
be programmed to operate entry gate
operators, security systems, entry door
locks and home or office lighting.

by calling the toll-free help line on
1-800-355-3515.
In-Vehicle Programming
This process is to program your hand-held
transmitter and your in-vehicle HomeLink
button.
Note: The programming steps below
assume you will be programming HomeLink
that was not previously programmed.
Note: Put a new battery in the hand-held
transmitter. This will ensure quicker training
and accurate transmission of the
radio-frequency signal. 1.
With your vehicle parked outside of the
garage, turn your ignition to the
on
position, but do not start your vehicle.

2. Hold your hand-held garage door
transmitter 2–6 in (5– 14 cm) away
from the HomeLink button you want
to program.
3. Using both hands, simultaneously, press and hold the desired HomeLink
button and the hand-held transmitter
button. DO NOT release either one until
the HomeLink indicator light flashes
slowly and then rapidly. When the
indicator light flashes rapidly, both
buttons may be released. The rapid
flashing indicates successful training.
Note: You may need to use a different
method if you live in Canada or have
difficulties programming your gate operator
or garage door opener. See
Gate Operator
/ Canadian Programming.
4. Press and hold the HomeLink button you programmed for two seconds, then
release. You may need to do this twice
to activate the door. If your garage door
does not operate, watch the HomeLink
indicator light.
If the indicator light stays on, the
programming is complete. No further
action is needed.
If the indicator light flashes rapidly for 2
seconds and then turns to a constant light,
the HomeLink button is not programmed
yet. See Programming Your Garage Door
Opener Motor.
To program additional buttons, repeat
Steps 1 – 4.

Note: You may need a ladder to reach the
unit and you may need to remove the cover
or lamp lens on your garage door opener. 1. Press the learn button on the garage
door opener motor and then you have
30 seconds to complete the next two
steps.
2. Return to your vehicle. 3.
Press and hold the function button you
want to program for 2 seconds, then
release. Repeat this step. Depending
on your brand of garage door opener,
you may need to repeat this sequence
a third time.
Gate Operator / Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission –
which may not be long enough for
HomeLink to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
“time-out” in the same manner.
Note: If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.

GENERAL INFORMATION
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage. WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always
open the garage door before you start the
engine. WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment.
If you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately
5 mi
(8 km) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You
can disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise. When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine.

Note:
If a person adds electrical or
electronic accessories or components to the
vehicle, the accessories or components may
adversely affect the low voltage battery
performance and durability and may also
affect the performance of other electrical
systems in the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
that matches the electrical requirements
of the vehicle.
Because your vehicle ’s engine is
electronically-controlled by a computer,
some engine control settings are
maintained by power from the low voltage
battery. Some engine computer settings,
like the idle trim and fuel trim strategy,
optimize the driveability and performance
of the engine. Some other computer
settings, like the clock and radio station
presets, are also maintained in memory by
power from the low voltage battery. When
a technician disconnects and connects the
low voltage battery, these settings are
erased. Complete the following procedure
in order to restore the settings:
1. With the vehicle at a complete stop, set the parking brake.
2. Shift the transmission into park (P).
3. Switch off all accessories.
4. Fully press the brake pedal and start the vehicle. 5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 315). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 85).
Reset the radio station presets. See
Audio System
(page 315).
6. Allow the engine to idle for at least one
minute. If the engine turns off, press
the accelerator pedal to start the
engine.
7. While the engine is running, press the brake pedal and shift into neutral (N).
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 12 mi (20 km)
to completely relearn the idle and fuel
trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.

Flex (TP3) , enUSA, Edition date: 201803, Second-Printing MaintenanceE142463

Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver
’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
This device complies with Part 15 of the
FCC Rules and with License exempt RSS
Standards of Industry Canada. 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. Note:
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.
Changing Tires With a Tire
Pressure Monitoring System Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically, at
least monthly, using an accurate tire gauge.
See Inflating Your Tires in this chapter.
Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to
your vehicle. The low tire pressure warning
light will turn on if the tire pressure is
significantly low. Once the light is

GENERAL INFORMATION
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. Radio Frequencies and Reception
Factors
AM and FM frequencies are established by
the Federal Communications Commission
(FCC) and the Canadian Radio and
Telecommunications Commission (CRTC).
Those frequencies are:
•
AM: 530-1710 kHz
• FM: 87.9-107.9 MHz
Note: Listening to loud audio for long
periods of time could damage your hearing. Radio Reception Factors
The further you travel from an AM or FM station, the
weaker the signal and the weaker the reception.
Distance and strength
Hills, mountains, tall buildings, bridges, tunnels, freeway
overpasses, parking garages, dense tree foliage and
thunderstorms can interfere with the reception.
Terrain
When you pass a ground-based broadcast repeating
tower, a stronger signal may overtake a weaker one and
result in the audio system muting.
