2014 FORD F250 service

On-Board Diagnostics (OBD-II)
Your vehicle is equipped with an on-board
diagnostics system (OBD-II) that monitors
the engine
’s emission control system. This
system protects the environment by
ensuring that your vehicle continues to
meet government emission standards. The
OBD-II system also assists your authorized
dealer 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 of temporary malfunctions are:
• the vehicle has run out of fuel —the
engine may misfire or run poorly
• poor fuel quality or water in the
fuel —the engine may misfire or run
poorly
• the fuel fill inlet may not have been
properly closed See Refueling (page
136).
• 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/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/Maintenance (I/M)
Testing
Some state/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, you may need to have
the vehicle serviced. See On-Board
Diagnostics (OBD-II).
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, your 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 the vehicle is ready for
I/M testing.
The OBD-II system monitors 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
may need to perform the following driving
cycle consisting of mixed city and highway
driving:
Drive on an expressway or highway for a
steady 15 minutes, followed by 20 minutes
of stop-and-go driving with at least four
30-second idle periods.
Allow the vehicle to sit for at least eight
hours without starting the engine. Then,
start the engine and complete the above
driving cycle. The engine must warm up to
its normal operating temperature. Once
started, do not turn off the engine until the
above driving cycle is complete. If the
vehicle is still not ready for I/M testing, you
will have to repeat the above driving cycle.

9. Start the vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as the halves are rotated
together.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
it may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
POWER TAKE-OFF
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation. Ford Super Duty Vehicles are approved for
use as a stationary (including split shaft
capability) or mobile power source, within
limits and operating guidelines detailed in
the Ford Truck Body Builders Layout Book,
found at www.fleet.ford.com/truckbbas,
and through the Ford Truck Body Builders
Advisory Service.

PARKING BRAKE
WARNING
Always set the parking brake fully
and make sure the transmission
selector lever is placed in position P.
Failure to set the parking brake and engage
park could result in vehicle roll-away,
property damage or bodily injury. Turn the
ignition to the lock position and remove
the key whenever you leave your vehicle. Apply the parking brake whenever your
vehicle is parked. Press the pedal
downward to set the parking brake. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release, pull the brake release lever
located at the lower left side of the
instrument panel.
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
WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake and put the transmission in park (P). WARNINGS
You must remain in your vehicle once
you have activated the system.
During all times, you are responsible
for controlling your vehicle,
supervising the system and
intervening, if required. If the engine is revved excessively, or
if a malfunction is detected, the
system will be deactivated.
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 will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your
foot from the brake to the accelerator
pedal. The brakes are released
automatically once the engine has
developed sufficient drive to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, (for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space).
The system will activate automatically on
any slope that will cause significant vehicle
rollback.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed.
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time will automatically be extended if
you are in the process of driving off.

System Indicator Lights and
Messages
WARNING
If a failure has been detected within
the AdvanceTrac system, the
stability control light will illuminate
steadily. Verify that the traction control
system was not manually disabled using
the stability control button. If the stability
control light still illuminates steadily, have
the system serviced by an authorized
dealer immediately. Operating your vehicle
with traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury and
death. The stability control light
temporarily illuminates on
engine start-up and flashes
when a driving condition activates the
stability system. The stability control off light
temporarily illuminates on
engine start-up and stays on
when you turn the traction control system
off, or if a problem occurs in the stability
system.

STEERING
To help prevent damage to the power
steering system:
•
Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three to five seconds
when the engine is running.
• Do not operate the vehicle with a low
power steering pump fluid level (below
the MIN mark on the reservoir).
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
(or if the engine is turned off), you can
steer the vehicle manually, but it takes
more effort.
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment
If any steering components are serviced or
replaced, install new fasteners (many are
coated with thread adhesive or have
prevailing torque features which may not
be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

Calculating the Maximum
Loaded Trailer Weight for Your
Vehicle
1. Start with the gross combined weight rating for your vehicle
model and axle ratio. See the
previous chart.
2. Subtract all of the following
that apply to your vehicle:
• Vehicle curb weight
• Hitch hardware weight, such as
a draw bar, ball, locks or weight
distributing hardware
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage
weight
• Aftermarket equipment weight.
This equals the maximum loaded
trailer weight for this combination.
Note: The trailer tongue load is
considered part of the payload for
your vehicle. Reduce the total
payload by the final trailer tongue
weight. Note:
Consult an authorized dealer
to determine the maximum trailer
weight allowed for your vehicle if
you are not sure.
ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
• Do not tow a trailer until you drive your
vehicle at least 1000 miles (1600
kilometers).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See your scheduled
maintenance information.
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
