When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use during
emergencies only. Operate the
vehicle in fail-safe mode only as long
as necessary to bring the vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. Never remove the coolant reservoir
cap while the engine is running or hot.
You have limited engine power when in the
fail-safe mode, so drive the vehicle with
caution. The vehicle will not be able to
maintain high-speed operation and the
engine will run rough. Remember that the
engine is capable of completely shutting
down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely
possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without repairing
the engine problem increases the chance of
engine damage. Take your vehicle to an
authorized dealer as soon as possible. Engine Fluid Temperature
Management (If Equipped) WARNING
To reduce the risk of collision and
injury, be prepared that the vehicle
speed may reduce and the vehicle
may not be able to accelerate with full
power until the fluid temperatures reduce. Your vehicle has been designed to pull a
trailer, but because of the added load, the
vehicle
’s engine may temporarily reach
higher temperatures during severe
operating conditions such as ascending a
long or steep grade while pulling a trailer
in hot ambient temperatures.
At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear
in the information display.
You may notice a reduction in the vehicle ’s
speed caused by reduced engine power.
Your vehicle has been designed to enter
this mode if certain high temperature/high
load conditions take place in order to
manage the engine ’s fluid temperatures.
The amount of speed reduction will
depend on the vehicle loading, towing,
grade, ambient temperature, and other
factors. If this occurs, there is no need to
pull off the road. The vehicle can continue
to be driven while this message is active
The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When
the engine coolant temperature decreases
to a more normal operating temperature,
the air conditioning will turn on once again.
If you notice any of the following:

Super Duty (TFA) Maintenance

•
the engine coolant temperature gauge
moves fully into the red (hot) area
• the coolant temperature warning light
illuminates
• the service engine soon indicator
illuminates. WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
1. Pull off the road as soon as safely
possible and place the vehicle in P
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After
several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant level.
4. If the coolant level is normal, you may restart your engine and continue on.
5. If the coolant is low, add coolant, restart the engine and take your vehicle
to an authorized dealer. See Adding
engine coolant in this chapter for more
information. Refer to fail-safe cooling
for additional information.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check and
change the transmission fluid and filter at
the correct service interval. See
Scheduled Maintenance (page 430).
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components. Checking Automatic Transmission
Fluid (If Equipped)
For scheduled intervals of the fluid checks
and changes, See
Scheduled
Maintenance (page 430). Your
transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
i.e., if the transmission slips or shifts slowly
or if you notice some sign of fluid leakage.
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is at normal
operating temperature (approximately
19 mi (30 km)
). Verify that the
transmission fluid temperature gauge,
located on the instrument cluster, is within
normal range.
1. Drive the vehicle
19 mi (30 km)until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and
engage the parking brake.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Latch the gearshift lever in P and leave
the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer to the Under Hood
Overview in this chapter for the
location of the dipstick.
6. Install the dipstick making sure it is fully
seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in the
designated area for normal operating
temperature or ambient temperature.
Low Fluid Level
Type A
231
Super Duty (TFA) Maintenance

TRANSFER CASE FLUID
CHECK
1. Clean the filler plug.
2. Remove the filler plug and inspect the
fluid level.
3. Add only enough fluid through the filler
opening so that the fluid level is at the
bottom of the opening.
Use only fluid that meets Ford
specifications. Refer to the See
Capacities and Specifications (page
292). section. BRAKE FLUID CHECK
Fluid levels between the
MIN and MAX
lines are within the normal operating range;
there is no need to add fluid. If the fluid
levels are outside of the normal operating
range, the performance of the system
could be compromised; seek service from
your authorized dealer immediately.
POWER STEERING FLUID
CHECK
Check the power steering fluid. See
Scheduled Maintenance
(page 430). If
adding fluid is necessary, use only
MERCON LV ATF
Note: This procedure is for vehicles with
gasoline engines. Vehicles with diesel
engines are similar. See Under Hood
Overview in your diesel supplement.
Check the fluid level when it is at ambient
temperature.
1. Check the fluid level in the reservoir. It should be between the MIN and MAX
range. Do not add fluid if the level is
within this range.
2. If the fluid level is low, add fluid to bring
the fluid level up to between the MIN
and MAX range.
3. Switch the engine on.
4. While the engine idles, turn the steering
wheel left and right several times.
5. Switch the engine off.

Note:
Electrical or electronic accessories
or components added to the vehicle by the
dealer or the owner may adversely affect
battery performance and durability.
Your vehicle is equipped with a Motorcraft
maintenance-free battery which normally
does not require additional water during
its life of service.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.
Because your vehicle ’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. Flexible fuel
vehicles (FFV) must also relearn the
ethanol content of the fuel for optimum
driveability and performance. To begin this
process
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P, turn off all
accessories.
3. Start the engine. Run the engine until it reaches normal operating
temperature.
4. Allow the engine to idle for at least one
minute.
5. Turn the A/C on and allow the engine to idle for at least one minute. 6. Release the parking brake. With your
foot on the brake pedal and with the
A/C on, put the vehicle in
D and allow
the engine to idle for at least one
minute.
• If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive the vehicle to complete the relearning process
•The vehicle may need to be driven
10 mi (16 km) or more to relearn the
idle and fuel trim strategy along
with the ethanol content for flexible
fuel vehicles.
• For flexible fuel vehicles, if you are
operating on E85, you may
experience poor starts or an
inability to start the engine and
driveability problems until the fuel
trim and ethanol content have been
relearned.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
Battery Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate

•
Never use strong household detergents
or soap, such as dish washing or
laundry liquid. These products can
discolor and spot painted surfaces.
• Never wash a vehicle that is “hot to the
touch ” or during exposure to strong,
direct sunlight.
• Dry your vehicle with a chamois or soft
terry cloth towel in order to eliminate
water spotting.
• Immediately remove items such as
gasoline, diesel fuel, bird droppings and
insect deposits because they can cause
damage to your vehicle ’s paintwork
and trim over time. Use Motorcraft Bug
and Tar Remover.
• Remove any exterior accessories, such
as antennas, before entering a car
wash.
Note: Suntan lotions and insect repellents
can damage any painted surface; if these
substances come in contact with your
vehicle, wash off as soon as possible.
Stripes or Graphics (if equipped)
Do not use a commercial or high-pressure
sprayer on the surface or edge of stripes
and graphics. This can cause damage to
the film and cause the edge of the film to
peel away from the vehicle surface.
Exterior Chrome
Note: Never use abrasive materials such as
steel wool or plastic pads as they can
scratch the chrome surface.
Note: Do not use chrome cleaner, metal
cleaner or polish on wheels and wheel
covers
247
Super Duty (TFA) Vehicle Care

•
Wash your vehicle first, using cool or
lukewarm water and a neutral pH
shampoo, such as Motorcraft Detail
Wash.
• Use Motorcraft Custom Bright Metal
Cleaner. Apply the product as you
would a wax to clean bumpers and
other chrome parts; allow the cleaner
to dry for a few minutes, then wipe off
the haze with a clean, dry rag.
• Do not apply cleaning product to hot
surfaces and do not leave cleaning
product on chrome surfaces longer
than the time recommended.
• Using other non-recommended
cleaners can result in severe and
permanent cosmetic damage.
Underbody
Flush the complete underside of your
vehicle frequently. Keep body and door
drain holes free from packed dirt.
Cleaning Plastic Exterior Parts
Use only approved products to clean
plastic parts
• For routine cleaning, use Motorcraft
Detail Wash.
• If tar or grease spots are present, use
Motorcraft Bug and Tar Remover.
WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax. •
Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
• Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
248
Super Duty (TFA) Vehicle Care

•
Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE EXHAUST WARNINGS
Failure to maintain the functional
holes, in the tailpipe section of the
exhaust, clean and free of debris or
foreign material may result in the holes
becoming blocked or plugged. Do not
modify or remove the tail-pipe section.
Blocked or plugged holes or
removal/modification of the system could
result in elevated exhaust gas
temperatures which may result in
vehicle/property damage or personal
injury. 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 diesel oxidation
catalytic converter and/or the diesel
particulate filter (DPF). The diesel
oxidation catalytic converter and/or the
DPF heats up to a high temperature after
only a short period of engine operation and
can stay hot even after the engine is turned
off. Failure to follow these instructions may
result in personal injury. The visible holes in the exhaust tip and the
holes under the shield just inboard of the
right rear tire(s) are functional. The holes
need to be kept clear of mud/debris or
foreign material to maintain proper
function of the exhaust system. Clean and
remove debris or foreign material if present
as needed. Spraying with a hose during
regular washing of vehicle should help
keep holes clean and clear of debris or
foreign material.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
•
Clean the windshield with a
non-abrasive glass cleaner.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
fluid.
