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 300).
• 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 189).
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.

The electric parking brake may apply when
you shift to park (P) without the brake
pedal fully pressed. The electric parking
brake applies when you shift to park (P)
on large slopes. The electric parking brake
releases with the drive away release
function or manually as described in the
Releasing the Electric Parking Brake
section. See Electric Parking Brake
(page 215).
Note: A warning tone sounds if you open
the driver door and you have not shifted the
transmission selector to park (P).
Reverse (R)
With the transmission selector 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 transmission selector in neutral
(N), you can start your vehicle and it is free
to roll. Hold the brake pedal down when in
this position.
Drive (D)
Drive (D) is the normal driving position for
the best fuel economy and smoothness.
Shift the transmission selector to drive (D)
to allow your vehicle to move forward and
shift automatically through the forward
gears.
The transmission shifts to the appropriate
gear for optimum performance based on
ambient temperature, road slope, vehicle
load and your input. Manual Mode (M) - Vehicles with
Paddle Shifters
With the transmission selector in manual
(M), the driver can change gears up or
down. After selecting the Manual (M)
button while the transmission range
selector is in Drive (D) position you now
have control of selecting the gear you
desire using shift buttons on the steering
wheel. See Understanding your SelectShift
Automatic
™ transmission later in this
section.
To exit manual mode, push the manual
(M) button on your transmission selector.
Low (L) - Vehicles without Paddle
Shifters
With the transmission selector in low (L),
your vehicle provides maximum engine
braking. You can shift the transmission into
low (L) at any vehicle speed. The intent is
not for use under extended or normal
driving conditions, and results in lower fuel
economy.
Automatic Return to Park
Note: This feature does not operate when
your vehicle is in Stay in Neutral mode or
neutral tow.
The transmission returns to park (P) if any
of the following occur:
• You switch the ignition off.
• Your seatbelt is not fastened, and you
open the driver door.
• The driver door is open, and you
unfasten your seatbelt.
If you switch the ignition off when your
vehicle is moving, your vehicle shifts into
neutral (N) until it slows down enough to
shift into park (P).

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 348).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Switch the engine off, move the
transmission to park (P) and apply the
parking brake. Inspect the accelerator
pedal and the area around it for any items
or debris that may be obstructing its
movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations. Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you switch the
ignition on or apply the parking
brake. If the light does not illuminate
during start up, remains on or flashes,
except when you switch the ignition on or
apply the parking brake, the anti-lock
braking system may be disabled. Have the
system checked by an authorized dealer.
If the anti-lock brake system is disabled,
normal braking is still effective. See
Warning Lamps and Indicators (page
107).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch
the ignition on or apply the
parking brake to confirm the
lamp is working. If it does not
illuminate when you switch the
ignition on, apply the parking brake, or if it
begins to flash at any time, have the
system checked by an authorized dealer.
If the brake warning lamp illuminates with
the parking brake released, have the
system checked immediately.
Regenerative Braking System
This feature is used to simulate the engine
braking of an internal combustion engine
and assist the standard brake system while
recovering some of the energy of motion
and storing it in the battery to improve fuel
economy. The standard brake system is
designed to fully stop the car if
regenerative braking is not available.
During regenerative braking, the motor is

Note:
Using deep snow/sand mode on dry,
hard surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.
Eco For efficient driving. This mode
helps deliver maximum fuel
efficiency and helps to increase
driving range.
Normal For everyday driving. This mode
is a perfect balance of
excitement, comfort and
convenience. This is the default mode after
each ignition cycle.
Slippery For less than ideal road
conditions, such as snow or ice
covered roads. Use this mode for
crossing terrain with a firm surface covered
with loose, wet or slippery material.
Slippery mode lowers throttle response
and, if provided with an automatic
transmission, optimizes shifting for slippery
surfaces.
Note: Using slippery mode on dry, hard
surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery surfaces. Sport For sporty driving with improved
performance handling, and
response. This mode increases
throttle response and provides a sportier
steering feel. If equipped with automatic
transmission, the powertrain system
provides improved gear holding, helping
your vehicle accelerate faster.
Tow/Haul For improved transmission
operation when towing a trailer
or a heavy load. This mode
moves upshifts to higher engine speeds to
reduce the frequency of transmission
shifting. This mode also provide engine
braking in all forward gears, which slows
your vehicle and assists you in controlling
your vehicle when descending a grade. The
amount of downshift braking provided
varies based on the amount you press the
brake pedal.
Trail For muddy, rutted, soft or uneven
terrain.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
