engine FORD FLEX 2019 Service Manual

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are: 1. Your vehicle has run out of fuel
—the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 154).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration. If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
160
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing Engine Emission Control

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.

AUTOMATIC TRANSMISSION
WARNING: Always fully apply the
parking brake. Make sure you shift into park
(P) for vehicles with an automatic
transmission. Switch the ignition off and
remove the key whenever you leave your
vehicle. WARNING:
Do not apply the brake
pedal and accelerator pedal
simultaneously. Applying both pedals
simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury.
Understanding the Positions of
Your Automatic Transmission
Putting your vehicle in gear:
1. Fully press down the brake pedal.
2. Move the gearshift lever into the desired gear.
3. Come to a complete stop.
4. Move the gearshift lever and securely latch it in park (P). Park (P)
This position locks the transmission and
prevents the wheels from turning.
Reverse (R)
With the gearshift lever in reverse (R), your
vehicle moves backward. Always come to
a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), your
vehicle can be started and is free to roll.
Hold the brake pedal down while in this
position.
Drive (D)
Drive (D) is the normal driving position for
the best fuel economy. The overdrive
function allows automatic upshifts and
downshifts through gears one through six.
Sport (S)
Moving the gearshift lever to sport (S):
•
Provides additional grade (engine)
braking and extends lower gear
operation to enhance performance for
uphill climbs, hilly terrain or
mountainous areas. This increases
engine RPM during engine braking.
• Provides additional lower gear
operation through the automatic
transmission shift strategy.
• Gears are selected more quickly and
at higher engine speeds.
SelectShift Automatic ™
Transmission
Your vehicle is equipped with a SelectShift
Automatic transmission gearshift lever.
The SelectShift Automatic transmission
gives you the ability to change gears up or
down (without a clutch) as desired.
162
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing TransmissionPRNDS
E142628

In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically makes
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as the
SelectShift determines that damage will
not be caused to the engine from
over-revving.
Note:
Engine damage may occur if you
maintain excessive engine revving without
shifting.
SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. It must be shifted manually by
pressing the + button.
If equipped with the toggle on the
gearshift lever:
• Press the (+) button to upshift.
• Press the (-) button to downshift. If equipped with steering wheel
paddles:
With your vehicle in drive (D), the paddle
shifters provide temporary manual control.
They allow you the ability to shift gears
quickly, without taking your hands off the
steering wheel. You can achieve extensive manual control
by moving the gearshift lever to the sport
(S) position.
•
Pull the right paddle (+) to upshift.
• Pull the left paddle (–) to downshift. The system determines when temporary
manual control is no longer in use and
returns to automatic control.
Upshift to the recommended shift speeds
according to the following chart:
Upshifts when accelerating (recom-
mended for best fuel economy)
Shift from:15 mph (24 km/h)
1 - 2
25 mph (40 km/h)
2 - 3
40 mph (64 km/h)
3 - 4
45 mph (72 km/h)
4 - 5
50 mph (80 km/h)
5 - 6
The instrument cluster displays your
currently selected gear.
Note: The system stays in manual control
until you make another shift selection (for
example, drive [D]).

Automatic Transmission Adaptive
Learning
This feature may increase durability and
provide consistent shift feel over the life
of your vehicle. A new vehicle or
transmission may have firm shifts, soft
shifts or both. This operation is considered
normal and does not affect function or
durability of the transmission. Over time,
the adaptive learning process fully updates
transmission operation.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.

USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels to
power the vehicle. This increases traction,
enabling you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot. The AWD system is
active all the time and requires no input
from the operator.
Note:
Your AWD vehicle is not intended for
off-road use. The AWD feature gives your
vehicle some limited off-road capabilities
in which driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions.
Operating your vehicle under other than
those conditions could subject the vehicle
to excessive stress which might result in
damage which is not covered under your
warranty. Note:
When an AWD system fault is
present, the warning Check AWD displays
in the information display. The AWD system
is not functioning correctly and defaults to
front-wheel drive. When this warning
displays, have your vehicle serviced at an
authorized dealer.
Note: The
AWD OFF message may also
appear in the information display if the AWD
system overheats and defaults to
front-wheel drive. This may occur if the
vehicle is operated in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After the engine has been
restarted and the AWD system has
adequately cooled, the AWD OFF message
will turn off and normal AWD function
returns. If the engine is not stopped, the
AWD OFF
message turns off when the
system cools and normal AWD function
returns.
All-Wheel Drive Messages Action / Description
AWD Messages
Displays if the AWD system disables to
protect itself. This may occur if you operate
the vehicle after installing the compact
spare tire, if the system is overheating or if
there is an issue with another vehicle
system that prevents the AWD system from
AWD OFF
operating. The AWD system resumes
166
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing All-Wheel Drive
(If Equipped)

WARNING: The use of
non-recommended tires and wheels could
cause steering, suspension, axle, transfer
case or power transfer unit failure. If you
have questions regarding tire replacement,
contact your authorized dealer as soon as
possible.
Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch
high profile tires on the rear axle) could
cause the AWD system to stop functioning
and default to front-wheel drive or damage
the AWD system. However, the AWD
system is capable of tolerating any
combination of new and worn tires of the
same original tire size. For example, using
3 worn tread tires and 1 new tread tire all
of the same original tire size, can be
tolerated by the AWD system.
Driving In Special Conditions With
All-Wheel Drive (AWD)
AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are
somewhat different from conventional
vehicles, both on and off the highway.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
will maximize the engine and transmission
cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect
overheating of the engine. Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
If Your Vehicle Goes Off the Edge of the
Pavement
• If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors,
with minor damage to your vehicle
rather than attempt a sudden return to
the pavement which could cause the
vehicle to slide sideways out of control
or rollover. Remember, your safety and
the safety of others should be your
primary concern.
If Your Vehicle Gets Stuck WARNING:
Always fully apply the
parking brake. Make sure you shift into park
(P) for vehicles with an automatic
transmission. Switch the ignition off and
remove the key whenever you leave your
vehicle.
168
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing All-Wheel Drive
(If Equipped)

WARNING: If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the
transmission and tires may occur or the
engine may overheat.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability
Control ™, it may be beneficial to
disengage the AdvanceTrac® with Roll
Stability Control ™ system while
attempting to rock the vehicle.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid
"over-driving" your vehicle (that is, turn
the steering wheel only as rapidly and
as far as required to avoid the
emergency). Excessive steering will
result in less vehicle control, not more.
Additionally, smooth variations of the
accelerator and/or brake pedal
pressure should be utilized if changes
in vehicle speed are called for. Avoid abrupt steering, acceleration or braking
which could result in an increased risk
of loss of vehicle control, vehicle
rollover and/or personal injury. Use all
available road surface to return the
vehicle to a safe direction of travel.
• In the event of an emergency stop,
avoid skidding the tires and do not
attempt any sharp steering wheel
movements.
• If the vehicle goes from one type of
surface to another (that is, from
concrete to gravel) there will be a
change in the way the vehicle responds
to a maneuver (steering, acceleration
or braking). Again, avoid these abrupt
inputs.
Sand
Most of the time traction control improves
tire traction by managing wheel slip
through Brake, Engine, and AWD
calibrations. However, during low speed
driving, disabling traction control in deep
sand can help keep the wheels moving to
maintain vehicle momentum.
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Do not drive your vehicle in deep sand for
an extended period of time. This could
cause the AWD system to overheat and
default to front-wheel drive. If this occurs,
an
AWD OFF message displays in the
information display. To resume normal
AWD function as soon as possible, stop
the vehicle in a safe location and stop the
engine for at least 10 minutes. After the
engine has been restarted and the AWD
169
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing All-Wheel Drive
(If Equipped)

system has adequately cooled, the AWD
OFF message turns off and normal AWD
function returns. In the event the engine is
not stopped, the AWD OFF message turns
off when the system cools and normal
AWD function returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L
(Low) gear when possible. L (Low) gear
operation will maximize the engine and
transmission cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect
overheating of the engine.
Avoid excessive speed because vehicle
momentum can work against you and
cause the vehicle to become stuck to the
point that assistance may be required from
another vehicle. Remember, you may be
able to back out the way you came if you
proceed with caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom
of the hubs (for trucks) (if possible) and
proceed slowly. If the ignition system gets
wet, the vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal. Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even AWD vehicles can lose traction
in slick mud. As when you are driving over
sand, apply the accelerator slowly and
avoid spinning your wheels. If the vehicle
does slide, steer in the direction of the slide
until you regain control of the vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts causes an imbalance that
could damage drive components.
Note:
Driving through deep water may
damage the transmission.
If the front or rear axle is submerged in
water, have the power transfer unit (PTU)
or rear axle serviced by an authorized
dealer. “Tread Lightly
” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities
in our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly. ”
Driving on Hilly or Sloping Terrain
Note: Avoid driving crosswise or turning on
steep slopes or hills. A danger lies in losing
traction, slipping sideways and possibly
rolling over. Whenever driving on a hill,
determine beforehand the route you will
use. Do not drive over the crest of a hill
without seeing what conditions are on the
other side. Do not drive in reverse over a hill
without the aid of an observer.
170
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing All-Wheel Drive
(If Equipped)E143950

Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should always
try to drive straight up or straight down.
When climbing a steep slope or hill, start
in a lower gear rather than downshifting to
a lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If you do stall out, do not try to turnaround
because you might roll over. It is better to
back down to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral; instead,
disengage overdrive or manually shift to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could
lose control. The front wheels have to be
turning in order to steer the vehicle.
Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not
“pump”
the brakes. Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end of
your vehicle slides while cornering, steer in
the direction of the slide until you regain
control of your vehicle.
Note: Excessive tire slippage can cause
driveline damage.
AWD vehicles have advantages over 2WD
vehicles in snow and ice but can skid like
any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking as well. Although an
AWD vehicle may accelerate better than
a two-wheel drive vehicle in snow and ice,
it won ’t stop any faster, because as in other
vehicles, braking occurs at all four wheels.
Do not become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Since your vehicle is
equipped with a four wheel (ABS), do not
“pump ” the brakes. See Hints on Driving
With Anti-Lock Brakes
(page 174).
