ECU FORD FLEX 2019 Owner's Guide

When changing the engine air filter, do not
allow debris or foreign material to enter
the air induction system. Engine
components are susceptible to damage
not covered by the vehicle Warranty.
Change the air filter element at the correct
interval. See Scheduled Maintenance
(page 442).
Incorrect component use can cause
damage not covered by the vehicle
Warranty. See
Motorcraft Parts (page
300).
To replace the air filter element do the
following: 1. Remove the clips that secure the air
filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the
air filter housing. 4.
Wipe any dirt or debris from the air filter
housing and cover to make sure no dirt
gets in the engine and that you have a
good seal.
5. Install a new air filter element. Be careful not to crimp the filter element
edges between the air filter housing
and cover. This could cause filter
damage and allow unfiltered air to
enter the engine if it is not properly
seated.
6. Install the air filter housing cover.
7. Engage the clips to secure the air filter housing cover to the air filter housing.

Follow these guidelines when using snow
tires and chains:
•
If possible, avoid fully loading your
vehicle.
• Use only SAE Class S snow chains,
snow cables or equivalent on the front
axle for P235/60R17, P235/60R18, and
P235/55R19 equipped vehicles. The
use of snow chains, snow cables or
other traction assist devices that are
larger than SAE Class S may cause
damage to your vehicle ’s wheel house,
suspension and/or body.
• Do not install tire chains, cables, or
optional traction devices on the rear
tires. This could cause damage to the
vehicle ’s wheel house or body.
• Do not use tire chains, cables, or
optional traction devices with
255/45R20 tires.
• Install cable chains securely, verifying
that the cables do not touch any wiring,
brake lines or fuel lines.
• Do not exceed 30 mph (48 km/h) with
tire cables on your vehicle.
• Drive cautiously. If you hear the cables
rub or bang against your vehicle, stop
and retighten the cables. If this does
not work, remove the cables to prevent
damage to your vehicle.
• Remove the tire cables when they are
no longer needed. Do not use tire
cables on dry roads. TIRE PRESSURE MONITORING
SYSTEM WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it may not
function. Each tire, including the spare, if
provided, should be checked
monthly when cold and inflated
to the inflation pressure recommended by
the vehicle manufacturer on the vehicle
placard or tire inflation pressure label.
Installation of any tires that are not the
original equipment tire size can cause the
speedometer to display incorrect vehicle
speed.
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle ’s handling and stopping ability.

Stowing the flat tire
If you are stowing the flat tire, remove the
L-shaped bolt from the external pocket of
the felt bag. With the third row seat in the
raised position, stand the flat tire in the
rear of the vehicle with the tire
’s valve stem
facing the rear of the vehicle. Fasten the
flat tire to the vehicle by inserting the
L-shaped bolt through one of the lug bolt
holes in the wheel. Turn it clockwise into
the threaded hole in the vehicle until the
tire is secured.
If you are stowing the temporary spare tire,
place the tire over the jack and secure it
with the large wing nut.
Stowing the jack 1. Fully collapse the jack, fold the lug
wrench socket into the handle and
place the jack and wrench into the felt

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that
attach the rotor to the hub so they do not interfere with the mounting surfaces of the
wheel. Installing wheels without correct metal-to-metal contact at the wheel mounting
surfaces can cause the wheel nuts to loosen and the wheel to come off while your vehicle
is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm) *

SYNC™ APPLICATIONS AND
SERVICES (If Equipped)
In order for the following features to work,
your cell phone must be compatible with
SYNC. To check your phone's
compatibility, visit www.SYNCMyRide.com,
www.SYNCMyRide.ca or
www.syncmaroute.ca.
• 911 Assist: Can alert 911 in the event of
an emergency.
911 Assist
(If Equipped) WARNING:
Unless the 911 Assist
setting is set on before a crash, the system
will not dial for help which could delay
response time, potentially increasing the
risk of serious injury or death after a crash. WARNING: Do not wait for 911 Assist
to make an emergency call if you can do it
yourself. Dial emergency services
immediately to avoid delayed response
time which could increase the risk of
serious injury or death after a crash. If you
do not hear 911 Assist within five seconds
of the crash, the system or phone may be
damaged or non-functional. WARNING: Always place your phone
in a secure location in your vehicle so it
does not become a projectile or get
damaged in a crash. Failure to do so may
cause serious injury to someone or damage
the phone which could prevent 911 Assist
from working properly. Note:
The SYNC 911 Assist feature must be
set on before the incident.
Note: Before setting this feature on, make
sure that you read the 911 Assist Privacy
Notice later in this section for important
information.
Note: If any user turns 911 Assist on or off,
that setting applies for all paired phones. If
911 Assist is turned off, either a voice
message plays or a display message (or
icon) comes on (or both) when your vehicle
is started after a previously paired phone
connects.
Note: Every phone operates differently.
While SYNC 911 Assist works with most
