GENERAL INFORMATION
WARNING:
Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage.
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:
Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic.
Always open the garage door before you
start the engine.
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.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 mi
(8 km) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You
can disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine.
KEYLESS STARTING
Note:
The keyless starting system may not
function if the key is close to metal objects
or electronic devices such as cellular
phones.

STEERING WHEEL LOCK
The steering wheel locks automatically
when you leave your vehicle and take the
intelligent access key with you. The
steering wheel unlocks automatically when
you enter your vehicle with the intelligent
access key.
Note:
You may need to turn the steering
wheel left or right if the wheel does not
unlock completely. This may happen in
certain situations, such as parking your
vehicle on a steep grade.
STARTING THE ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.
Note:
You can crank the engine for a total
of 60 seconds, without the engine starting,
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, you can crank
the engine three times for 20 seconds each,
without the engine starting, to reach the 60
second time limit. If you exceed the
cranking time, you cannot attempt to start
the engine for at least 15 minutes. After 15
minutes, you have a 15 second time limit to
crank the engine. You need to wait 60
minutes before you crank the engine again
for 60 seconds.
Before starting the engine, check the
following:
•
Make sure all occupants fasten their
seatbelts.
•
Make sure the headlamps and
electrical accessories are off.
•
Make sure the parking brake is on.
•
Move the transmission selector into
park (P).

SAFETY PRECAUTIONS
WARNING:
Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire.
WARNING:
The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury.
WARNING:
Fuels can cause serious
injury or death if misused or mishandled.
WARNING:
Fuel may contain
benzene, which is a cancer-causing
agent.
WARNING:
When refueling always
shut the engine off and never allow
sparks or open flames near the fuel tank
filler valve. Never smoke or use a cell
phone while refueling. Fuel vapor is
extremely hazardous under certain
conditions. Avoid inhaling excess fumes.
Follow these guidelines when refueling:
•
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
•
Always switch the engine off before
refueling.
•
Automotive fuels can be harmful or
fatal if swallowed. Fuel is highly toxic
and if swallowed can cause death or
permanent injury. If fuel is swallowed
immediately call a physician, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
apparent for hours.
•
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases,
excessive or prolonged breathing of
fuel vapor can cause serious illness and
permanent injury.
•
Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush
with water for 15 minutes and seek
medical attention. Failure to seek
proper medical attention could lead to
permanent injury.
•
Fuels can be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
thoroughly wash your skin with soap
and water. Repeated or prolonged skin
contact causes skin irritation.
•
Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing fuel vapors could cause an
adverse reaction, serious personal
injury or sickness. Immediately call a
physician if you experience any adverse
reactions.
FUEL QUALITY
Choosing the Right Fuel
E185193
93
Fuel and Refueling
Use only premium unleaded gasoline with
a minimum pump (R+M)/2 octane rating
of 91. For optimal performance, use
premium unleaded gasoline with an octane
rating of 93 or higher.
The use of the correct fuel is an important
part of the proper maintenance of your
vehicle, and a condition of the vehicle
Warranty. For this vehicle, the use of
gasoline with an octane level of 91 or
higher is required. The use of gasoline with
an octane rating lower than 91 will
invalidate the vehicle Warranty. It can
degrade vehicle performance and lead to
severe mechanical damage.
We recommend Top Tier detergent
gasolines, where available, to help
minimize engine deposits and maintain
optimal vehicle and engine performance.
For additional information, refer to
www.toptiergas.com.
Note:
Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.
Do not use:
•
Diesel fuel.
•
Fuels containing kerosene or paraffin.
•
Fuel containing more than 15% ethanol
or E85 fuel.
•
Fuels containing methanol.
•
Fuels containing metallic-based
additives, including manganese-based
compounds.
•
Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
•
Leaded fuel (using leaded fuel is
prohibited by law).
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
Do not be concerned if the engine
sometimes knocks lightly. However, if it
knocks heavily under most driving
conditions while you are using fuel with the
recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is located in the
storage compartment under the rear hatch.
RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
•
Add a minimum of 1.3 gal (5 L) of fuel
to restart the engine.
•
You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal.
Note:
If your vehicle is on a steep slope,
more fuel may be required.

Fuel and Refueling
Filling a Portable Fuel Container
WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container.
Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an
ungrounded fuel container:
•
Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
•
Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
•
Keep the fuel pump nozzle in contact
with the fuel container when filling it.
•
Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container
WARNING:
Do not insert the nozzle
of a fuel container or an aftermarket
funnel into the fuel filler neck. This may
damage the fuel system filler neck or its
seal and cause fuel to run onto the
ground.
WARNING:
Do not try to pry open
or push open the capless fuel system
with foreign objects. This could damage
the fuel system and its seal and cause
injury to you or others.
WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See

action should dislodge any debris that
may be preventing the fuel filler inlet
from fully closing.
6. Fully close the fuel filler door.
Note:
If this action corrects the problem
the message may not immediately reset. If
the message remains and a warning lamp
illuminates, have your vehicle checked as
soon as possible.
FUEL CONSUMPTION
The advertised capacity is the indicated
capacity and the empty reserve combined.
Indicated capacity is the difference in the
amount of fuel in the fuel tank and when
the fuel gauge indicates empty.
Note:
The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Note:
When refueling your vehicle after the
fuel gauge indicates empty, you might not
be able to refuel the full amount of the
advertised capacity due to the empty
reserve still present in the fuel tank.
97
Fuel and Refueling
Filling the Fuel Tank
For consistent results when refueling:
•
Always switch the ignition off before
refueling. If you leave the engine
running, you will get an inaccurate
reading.
•
Use the same fill rate each time you fill
the tank.
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.
5. 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.
Conditions
•
Heavily loading your vehicle reduces
fuel economy.
•
Carrying unnecessary weight in your
vehicle may reduce fuel economy.
•
Adding certain accessories to your
vehicle 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.
99
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
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
•
Use only the specified fuel listed.
•
Do not switch the ignition off when your
vehicle is moving.
•
Avoid running out of fuel.
•
Perform scheduled maintenance items
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,
use parts equivalent to genuine Ford Motor
Company parts in performance and
durability.
100
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 could 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 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
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.
101
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 vehicle on 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:
