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:
230
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

Fuel system
•
Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm there are no cooling system
leaks, and fluid is at the recommended
level.
Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery, it
may be advisable to disconnect the
battery cables to ensure battery charge
is maintained for quick starting.
Note: If battery cables are disconnected, it
will be necessary to reset memory features.
Brakes
• Make sure brakes and parking brake
are fully released.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 feet (8
meters) every 15 days to lubricate
working parts and prevent corrosion. Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
•
Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage (mice/squirrel nests).
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle 15 feet (4.5 meters) back
and forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If the battery was removed, clean the
battery cable ends and inspect.
Contact your authorized dealer if you have
any concerns or issues.
