Filling the Fuel Tank
For consistent results when refueling:
•
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 one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine ’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km)
to 3,000 mi
(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 fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used. Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle's fuel economy under current
driving conditions. Keeping records during
summer and winter will show how
temperature impacts fuel economy.
Conditions
•
Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.

EMISSION LAW
WARNING
Do not remove or alter the original
equipment floor covering or
insulation between it and the metal
floor of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal
floor. Failure to follow these instructions
may result in fire or personal injury. U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws.
Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
148
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Engine Emission Control

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNINGS
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. The normal operating temperature
of the exhaust system is very high.
Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNINGS
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. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 215).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts 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.

Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Engine Emission Control

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 144).
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.
150
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, 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
WARNINGS
Always fully apply the parking brake
and make sure you shift into park (P).
Switch the ignition off and remove
the key whenever you leave your vehicle. 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.
Press and hold the button on the front
of the selector lever.
3. Move the selector lever into the desired
gear.
4. Release the button and your transmission will remain in the selected
gear. Park (P)
This position locks the transmission and
prevents the wheels from turning. Reverse (R)
With the selector lever in reverse (R), your
vehicle will move backward. Always come
to a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the selector 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 selector 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 will increase
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 SelectShift automatic transmission
gives you the ability to manually change
gears.

•
Press the (+) button to upshift.
• Press the (-) button to downshift.
If equipped with steering wheel
paddles: •
Pull the right paddle (+) to upshift.
• Pull the left paddle (-) to downshift.
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 selector
lever to sport (S).
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)

3 - 4
45 mph (72 km/h)
4 - 5
50 mph (80 km/h)
5 - 6
The instrument cluster will display the
selected gear that you are currently in and
a shift indicator arrow to assist in
optimizing shifting.
SelectShift will automatically make some
shifts for you in the event that your engine
speed is running at too high, or too low an
RPM.
Note: Engine damage may occur if
excessive engine revving is held without
shifting.
Brake-Shift Interlock WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can
roll freely. To avoid unwanted vehicle
movement, always fully apply the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate. 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. 153

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.

USING ALL-WHEEL DRIVE (If
Equipped)
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: The Power Transfer Unit (PTU) in
Taurus SHO™ performance package
vehicles does not require any normal
scheduled maintenance. The system is
electronically monitored and notifies the
driver of required service by displaying the
message
Change AWD Power Transfer
Unit Lube in the information display. The
PTU lubricant will be more likely to require
a fluid change if the vehicle has experienced
extended periods of extreme or severe duty
cycle driving. Do not check or change the
PTU lubricant unless the unit shows signs
of leakage or a message indicating required
service is displayed. Contact an authorized
dealer for service if the PTU was submerged
in water and to reset the PTU lube life
monitor. 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 defaulted
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.
