FUEL CONSUMPTION
Filling the tank
The advertised capacity is the indicated capacity and the empty reserve
combined. Indicated capacity is the difference in the amount of fuel in a
full tank and a tank when the fuel gauge indicates empty. Empty reserve
is the amount of fuel in the tank after the fuel gauge indicates empty.
Note:The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your vehicle
after the fuel gauge indicates empty, you might not be able to refuel the
full amount of the advertised capacity of the fuel tank due to the empty
reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the ignition off before fueling; an inaccurate reading results if the
engine is left running.
•Use the same fill rate (low–medium–high) each time the tank is filled.
•Allow no more than two automatic click–offs when filling.
Results are most accurate when the filling method is consistent.
Calculating fuel economy
Do not measure fuel economy during the first 1,000 miles (1,600 km) of
driving (this is your engine’s break-in period); a more accurate
measurement is obtained after 2,000 miles–3,000 miles (3,200 km–4,800
km). Also, fuel expense, frequency of fill-ups or fuel gauge readings are
not accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy as follows:
Standard: Divide miles traveled by gallons used.
Metric: Multiply liters used by 100, then divide by kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter show how temperature impacts fuel economy.
In general, lower temperatures mean lower fuel economy.

EMISSION CONTROL SYSTEM
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
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 dealer inspect your
vehicle immediately. Do not drive if you smell exhaust fumes.
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed inscheduled maintenance information
performed according to the specified schedule.
The scheduled maintenance items listed inscheduled maintenance
informationare essential to the life and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraftor Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
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 yourWarranty Guidefor complete emission warranty
information.
On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet government
emission standards. The OBD-II system also assists your authorized
dealer 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. The 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 been properly closed. SeeEasy Fuel
“no cap” fuel systemin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected 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 the engine is started. A driving cycle
consists of a cold engine startup followed by mixed city/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/Maintenance (I/M) Testing
Some state/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, the vehicle may need to be serviced. Refer toOn-board
diagnostics (OBD-II)in this chapter.
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 considered
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
the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.

AUTOMATIC TRANSMISSION
WARNING:Always set the parking brake fully and make sure the
gearshift is latched in P (Park). Turn the ignition to the off position
and remove the key whenever you leave your vehicle.
Your vehicle has been designed to improve fuel economy by reducing fuel
usage while coasting or decelerating. When you take your foot off the
accelerator pedal and the vehicle begins to slow down, the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived as
a light to medium braking sensation when removing your foot from the
accelerator pedal.
P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
•Press the brake pedal
•Move the gearshift lever into the desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and securely latch it in P (Park)
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R (Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Drive) with Overdrive
The normal driving position for the best fuel economy. Transmission
operates in gears one through six.

D (Drive) with Grade Assist (if equipped)
Press the transmission control
switch on the side of the gearshift
lever to activate grade assist.
Grade assist:
•Improves driving experience in hilly terrain or mountainous areas by
providing additional grade (engine) braking and extends lower gear
operation on uphill climbs.
•Provides additional engine braking through the automatic transmission
shift strategy which reacts to vehicle inputs (vehicle acceleration,
accelerator pedal, brake pedal and vehicle speed).
•Allows the transmission to select gears that will provide the desired
engine braking based on the vehicle inputs mentioned above. This will
increase engine RPM during engine braking.
•The grade assist lamp in the instrument cluster is
illuminated.
Grade assist is designed to provide optimal gear selection in hilly terrain
or mountainous areas. It is recommended that you return to D (Drive) on
flat terrain to provide the best fuel economy and transmission function.
Press the transmission control switch again to return to O/D (overdrive
mode).
•The grade assist lamp in the instrument cluster will not be illuminated.
•The transmission will operate in gears one through six.
L (Low)
•Provides maximum engine braking
•Will downshift to the lowest available gear for the current vehicle
speed; allows for first gear when vehicle reaches lower speeds
•Is not intended for use under extended or normal driving conditions
and results in lower fuel economy.

S (Sport)
Moving the gearshift lever to S (Sport):
•Provides additional grade (engine) braking and extends lower gear
operation to enhance performance for uphill climbs, hilly terrain or
mountainous areas. This will increase engine RPM during engine
braking.
•Provides additional lower gear operation through the automatic
transmission shift strategy which reacts to vehicle inputs (vehicle
acceleration, accelerator pedal, brake pedal and vehicle speed).
•Gears are selected more quickly and at higher engine speeds.
SelectShift Automatic™ Transmission (If Equipped)
Note:Your transmission must be in S (Sport) for SelectShift to operate
properly.
Your SelectShift automatic transmission gives you the ability to manually
change gears if you’d like. To use SelectShift, move the gearshift lever
into S (Sport). Now you can use select shift to manually change gears.
Note:The system will stay in S (Sport) until the gear shift lever is
moved into another gear for example P (park) or D (Drive).
If your vehicle is equipped with the +/– buttons on the side of your
gearshift lever:
•Press (–) on the gearshift lever
button to manually downshift the
transmission.
•Press (+) on the gearshift lever
button to manually upshift the
transmission.
212Transmission
2013 Flex(471)
Owners Guide gf, 1st Printing

If your vehicle is equipped with paddles on the steering wheel:
•Pull the left paddle(–)to
downshift the transmission.
•Pull the right paddle (+) to upshift
the transmission.
Upshift to the recommended shift speeds according to the following
chart:
Upshifts when accelerating (recommended for best fuel
economy)
Shift from:
1 - 2 15 mph (24 km/h)
2 - 3 25 mph (40 km/h)
3 - 4 40 mph (64 km/h)
4 - 5 45 mph (72 km/h)
5 - 6 50 mph (80 km/h)
The instrument cluster will show the selected gear you are currently in.
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, SelectShift will automatically make some downshifts
if it has determined that you have not downshifted in time. It will still
allow you to downshift at any time as long as SelectShift determines that
the engine will not be damaged from over-revving.
Note:If manual control is no longer desired, you must return the gear
shift lever from S (Sport) to D (Drive).
Note:Engine damage may occur if excessive engine revving is held
without shifting.
Automatic transmission adaptive learning
This feature is designed to increase durability and provide consistent
shift feel over the life of the vehicle. A new vehicle or transmission may
have firm and/or soft shifts. This operation is considered normal and will
not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
Additionally, whenever the battery is disconnected or a new battery
installed, the strategy must be relearned.
