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 WARNING:
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. WARNING:
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. 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
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 212).
• 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.

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 140).
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.
147
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201806, First-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.

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: 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.

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
normal operation and clears this message
after you install the road tire and you switch
the ignition on and off, or after you allow
the system to cool. If this message remains
on, have a qualified technician service your
vehicle to repair other vehicle systems.
Displayed in conjunction with the power-
train malfunction/reduced power light
when the system is not operating properly.
If the warning stays on or continues to
come on, contact your authorized dealer
as soon as possible.

Operating AWD Vehicles With
Spare Tires
A spare tire of a different size other than
the tire provided should never be used. The
AWD system may disable automatically
and enter front-wheel drive only mode to
protect driveline components if a non-full
sized tire is installed. This condition may
display an AWD OFF message in the
information display. If there is an AWD OFF
message in the information display from
using a non-full sized spare tire, this
indicator should turn off after reinstalling
the repaired or replaced normal road tire and cycling the ignition off and on. It is
recommended to reinstall the repaired or
replaced road tire 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.

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. 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.

HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
PARKING BRAKE WARNING: Always set the parking
brake fully and make sure the
transmission is locked in park (P). Failure
to set the parking brake and engage park
could result in vehicle roll-away, property
damage or bodily injury.
To set the parking brake, press the parking
brake pedal down to its fullest extent. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release the parking brake, press the
parking brake pedal down again.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system will turn
off if a malfunction is apparent or if you
rev the engine excessively. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
161
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201806, First-Printing Brakes

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information
display showing system status. You can switch the system off by either
using the information display controls or
the switch.
Using the Information Display
Controls
You can switch this feature off or on in the
information display.
See General
Information (page 85).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off
or on.
The switch illuminates when traction
control is off.
System Indicator Lights and
Messages The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you switch the traction control
system off.

When you think your vehicle has enough
space in front and behind it, or you hear a
solid tone from the parking aid
(accompanied by a touchscreen display
message and a chime), bring your vehicle
to a complete stop.
When automatic steering is complete, the
system displays a message and a chime
sounds, indicating that the active park
assist process is finished. You are
responsible for checking the parking job
and making any necessary corrections
before leaving your vehicle.
Deactivating the Park Assist
Feature
Manually deactivate the system by:
•
Pressing the active park assist button
during an active maneuver.
• Grabbing the steering wheel during an
active maneuver. •
Driving above approximately 22 mph
(35 km/h) for 30 seconds during an
active park search.
• Driving above
6 mph (9 km/h) during
automatic steering.
• Switching off the traction control
system.
Certain vehicle conditions can also
deactivate the system, such as:
• Traction control has activated.
• There is an anti-lock brake system
activation or failure.
If a problem occurs with the system, a
warning message displays accompanied
by a tone. Occasional system messages
may occur in normal operation. For
recurring or frequent system faults, contact
an authorized dealer to have your vehicle
serviced.
Troubleshooting the System The system does not look for a space
The traction control system may be off.
The transmission is in reverse (R). Your vehicle must be moving forward to detect a
parking space. The system does not offer a particular space
The sensors may be covered. For example, with snow, ice or dirt. Covered sensors can
affect the system's functionality
There is not enough room in the parking space for your vehicle to safely park.
There is not enough space for the parking maneuver on the opposite side of the parking
space.

STEERING
Electric Power Steering
WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked by an
authorized dealer. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Obtain immediate service
from an authorized dealer, failure to do
so may result in loss of steering control.
Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation. Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.
COLLISION WARNING SYSTEM
