On Board Diagnostics Data Link
Connector
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.
Your vehicle has an OBD Data Link
Connector (DLC) that is used in
conjunction with a diagnostic scan tool for
vehicle diagnostics, repairs and
reprogramming services. Installing an
aftermarket device that uses the DLC
during normal driving for purposes such as
remote insurance company monitoring,
transmission of vehicle data to other
devices or entities, or altering the
performance of the vehicle, may cause
interference with or even damage to
vehicle systems. We do not recommend
or endorse the use of aftermarket plug-in
devices unless approved by Ford. The
vehicle Warranty will not cover damage
caused by an aftermarket plug-in device.
MOBILE COMMUNICATIONS
EQUIPMENT 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.
Using mobile communications equipment
is becoming increasingly important in the
conduct of business and personal affairs.
However, you must not compromise your
own or others’
safety when using such
equipment. Mobile communications can
enhance personal safety and security when
appropriately used, particularly in
emergency situations. Safety must be
paramount when using mobile
communications equipment to avoid
negating these benefits. Mobile
communication equipment includes, but
is not limited to, cellular phones, pagers,
portable email devices, text messaging
devices and portable two-way radios.
EXPORT UNIQUE OPTIONS
For your particular global region, your
vehicle may be equipped with features and
options that are different from the features
and options that are described in this
Owner ’s Manual. A market unique
supplement may be supplied that
complements this book. By referring to the
market unique supplement, if provided,
you can properly identify those features,
recommendations and specifications that
are unique to your vehicle. This Owner ’s
Manual is written primarily for the U.S. and
Canadian Markets. Features or equipment
listed as standard may be different on units
built for export. Refer to this Owner ’s
Manual for all other required
information and warnings.

GENERAL INFORMATION
See the following sections for directions
on how to properly use safety restraints
for children.
WARNING: Always make sure your
child is secured properly in a device that is
appropriate for their height, age and
weight. Child safety restraints must be
bought separately from your vehicle.
Failure to follow these instructions and
guidelines may result in an increased risk
of serious injury or death to your child. WARNING:
All children are shaped
differently. The National Highway Traffic
Safety Administration and other safety
organizations, base their recommendations
for child restraints on probable child height,
age and weight thresholds, or on the
minimum requirements of the law. We
recommend that you check with a NHTSA
Certified Child Passenger Safety Technician (CPST) to make sure that you
properly install the child restraint in your
vehicle and that you consult your
pediatrician to make sure you have a child
restraint appropriate for your child. To
locate a child restraint fitting station and
CPST, contact NHTSA toll free at
1-888-327-4236 or go to
www.nhtsa.dot.gov. In Canada, contact
Transport Canada toll free at
1-800-333-0371 or go to www.tc.gc.ca to
find a Child Car Seat Clinic in your area.
Failure to properly restrain children in child
restraints made especially for their height,
age and weight, may result in an increased
risk of serious injury or death to your child.
WARNING: On hot days, the
temperature inside the vehicle can rise very
quickly. Exposure of people or animals to
these high temperatures for even a short
time can cause death or serious heat
related injuries, including brain damage.
Small children are particularly at risk.

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

Use a child restraint (sometimes called an
infant carrier, convertible seat, or toddler
seat) for infants, toddlers or children
weighing 40 lb (18 kg) or less (generally
age four or younger).
Using Lap and Shoulder Belts WARNING:
Do not place a rearward
facing child restraint in front of an active
airbag. Failure to follow this instruction
could result in personal injury or death. WARNING:
Properly secure children
12 years old and under in a rear seating
position whenever possible. If you are
unable to properly secure all children in a
rear seating position, properly secure the
largest child on the front seat. If you must
use a forward facing child restraint on the
front seat, move the seat as far back as
possible. Failure to follow these
instructions could result in personal injury
or death. WARNING: Depending on where you
secure a child restraint, and depending on
the child restraint design, you may block
access to certain seatbelt buckle
assemblies and LATCH lower anchors,
rendering those features potentially
unusable. To avoid risk of injury, make sure
occupants only use seating positions
where they are able to be properly
restrained.
When installing a child restraint with
combination lap and shoulder belts:
• Use the correct seatbelt buckle for that
seating position.
• Insert the belt tongue into the proper
buckle until you hear a snap and feel it
latch. Make sure the tongue is securely
fastened in the buckle. •
Keep the buckle release button
pointing up and away from the safety
seat, with the tongue between the child
restraint and the release button, to
prevent accidental unbuckling.
• Place the vehicle seat upon which the
child restraint will be installed in the
upright position.
• For second-row seating positions,
adjust the recliner slightly to improve
child restraint fit. If needed, remove the
head restraints.
• For third-row seating positions, stow
the head restraints to improve child
restraint fit. See Head Restraints
(page 121).
• Put the seatbelt in the automatic
locking mode. See Step 5. This vehicle
does not require the use of a locking
clip.
Perform the following steps when
installing the child restraint with
combination lap and shoulder belts:
Note: Although the child restraint
illustrated is a forward facing child restraint,
the steps are the same for installing a rear
facing child restraint.
Note: The lock-off device on some child
restraints may not accommodate the
shoulder portion of the inflatable seatbelt.
Follow all instructions provided by the
manufacturer of the child restraint regarding
the necessary and proper use of the lock-off
device. In some instances these devices
have been provided only for use in vehicles
with seatbelt systems that would otherwise
require a locking clip.

Standard Seatbelts
1. Position the child restraint in a seat
with a combination lap and shoulder
belt. 2. After positioning the child restraint in
the proper seating position, pull down
on the shoulder belt and then grasp the
shoulder belt and lap belt together
behind the belt tongue. 3.
While holding the shoulder and lap belt
portions together, route the tongue
through the child restraint according
to the child restraint manufacturer's
instructions. Be sure the belt webbing
is not twisted. 4. Insert the belt tongue into the proper
buckle (the buckle closest to the
direction the tongue is coming from)
for that seating position until you hear
a snap and feel the latch engage. Make
sure the tongue is latched securely by
pulling on it.

5. To put the retractor in the automatic
locking mode, grasp the shoulder
portion of the belt and pull downward
until you pull all of the belt out.
Note: The automatic locking mode is
available on the front passenger and rear
seats.
6. Allow the belt to retract to remove slack. The belt clicks as it retracts to
indicate it is in the automatic locking
mode.
7. Try to pull the belt out of the retractor to make sure the retractor is in the
automatic locking mode (you should
not be able to pull more belt out). If the
retractor is not locked, unbuckle the
belt and repeat Steps 5 and 6. 8.
Remove remaining slack from the belt.
Force the seat down with extra weight,
for example, by pressing down or
kneeling on the child restraint while
pulling up on the shoulder belt in order
to force slack from the belt. This is
necessary to remove the remaining
slack that exists once you add the extra
weight of the child to the child restraint.
It also helps to achieve the proper
snugness of the child restraint to your
vehicle. Sometimes, a slight lean
toward the buckle provides extra help
to remove remaining slack from the
belt.
9. Attach the tether strap (if the child restraint is equipped). 10. Before placing the child in the seat,
forcibly move the seat forward and
back to make sure the seat is securely
held in place. To check this, grab the
seat at the belt path and attempt to
move it side to side and forward and
back. There should be no more than
1 in (2.5 cm) of movement for proper
installation.
We recommend checking with a NHTSA
Certified Child Passenger Safety
Technician to make certain the child
restraint is properly installed. In Canada,
check with Transport Canada for referral
to a Child Car Seat Clinic.

Inflatable Seatbelts
1. Position the child restraint in a seat
with a combination lap and shoulder
belt. 2. After positioning the child restraint in
the proper seating position, grasp the
shoulder belt and lap belt together
behind the belt tongue. 3.
While holding the shoulder and lap belt
portions together, route the tongue
through the child restraint according
to the child restraint manufacturer's
instructions. Be sure the belt webbing
is not twisted. 4. Insert the belt tongue into the proper
buckle (the buckle closest to the
direction the tongue is coming from)
for that seating position until you hear
a snap and feel the latch engage. Make
sure the tongue is latched securely by
pulling on it.

Using Lower Anchors and Tethers
for CHildren (LATCH) WARNING: Do not attach two child
safety restraints to the same anchor. In a
crash, one anchor may not be strong
enough to hold two child safety restraint
attachments and may break, causing
serious injury or death. WARNING: Depending on where you
secure a child restraint, and depending on
the child restraint design, you may block
access to certain seatbelt buckle
assemblies and LATCH lower anchors,
rendering those features potentially
unusable. To avoid risk of injury, make sure
occupants only use seating positions
where they are able to be properly
restrained.
The LATCH system is composed of three
vehicle anchor points: two lower anchors
where the seat backrest and seat cushion
meet (called the seat bight) and one top
tether anchor behind that seating position.
LATCH compatible child restraints have
two rigid or webbing mounted
attachments that connect to the two lower
anchors at the LATCH equipped seating
positions in your vehicle. This type of
attachment method eliminates the need
to use seatbelts to attach the child
restraint. However, you can still use the
seatbelt to attach the child restraint. For
forward-facing child restraints, you must
attach the top tether strap to the proper
top tether anchor if a top tether strap has
been provided with your child restraint.
Your vehicle has LATCH lower anchors for
child restraint installation at the seating
positions marked with the child restraint
symbol.
