air condition FORD SUPER DUTY 2004 1.G User Guide

The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toAir bag readinesssection
in theInstrument clusterchapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.

NHTSA deactivation criteria (excluding Canada)
1.Infant.An infant (less than 1 year old) must ride in the front seat
because:
•the vehicle has no rear seat;
•the vehicle has a rear seat too small to accommodate a rear-facing
infant seat; or
•the infant has a medical condition which, according to the infant’s
physician, makes it necessary for the infant to ride in the front so that
the driver can constantly monitor the child’s condition.
2.Child age 1 to 12.A child age 1 to 12 must ride in the front seat
because:
•the vehicle has no rear seat;
•although children ages 1 to 12 ride in the rear seat(s) whenever
possible, children ages 1 to 12 sometimes must ride in the front
because no space is available in the rear seat(s) of the vehicle; or
•the child has a medical condition which, according to the child’s
physician, makes it necessary for the child to ride in the front seat so
that the driver can constantly monitor the child’s condition.
3.Medical condition.A passenger has a medical condition which,
according to his or her physician:
•causes the passenger air bag to pose a special risk for the passenger;
and
•makes the potential harm from the passenger air bag in a crash
greater than the potential harm from turning OFF the air bag and
allowing the passenger, even if belted, to hit the dashboard or
windshield in a crash.
This vehicle has special energy management safety belts for the
driver and right front passenger. These particular belts are
specifically designed to work with air bags to help reduce the risk of
injury in a collision. The energy management safety belt is designed to
give or release additional belt webbing in some accidents to reduce
concentration of force on an occupant’s chest and reduce the risk of
certain bone fractures and injuries to underlying organs. In a crash, if
the air bag is turned OFF, this energy management safety belt might
permit the person wearing the belt to move forward enough to incur a
serious or fatal injury. The more severe the crash, and the heavier the
occupant, the greater the risk is. Be sure the air bag is turned ON for
any person who does not qualify under the NHTSA deactivation
criteria.

Using the engine block heater (if equipped)
Use of an engine block heater is
strongly recommended if you live in
a region where temperatures reach
-23°C (-10°F) or below. For best
results, plug the heater in at least
three hours before starting the
vehicle. The heater can be plugged
in the night before starting the
vehicle. The plug for the block
heater is exposed in the front of the
vehicle, beneath the grille. Vehicles
equipped with a gasoline engine have the plug exposed on the driver
side of the vehicle; vehicles equipped with a Diesel engine have the plug
exposed on the passenger side of the vehicle.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
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 should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.

Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED)
Some automatic transmission vehicles may be equipped with a
Transmission Power Take-Off Provision, Option Code 62R. These
vehicles have a special transmission that includes a port on the left hand
side to mount an aftermarket PTO, an internal PTO gear, and calibration
for PTO usage. The actual PTO and related equipment is not offered by
Ford Motor Company, but is installed by the aftermarket.
The PTO gear in the transmission will drive the aftermarket PTO while
driving the vehicle. Therefore, some additional gear noise that may result
is normal. Also, the transmission upshift and downshift schedules will be
reduced by about 15% and may result in a firmer shift feel during PTO
mobile applications.
A more complete description of PTO operation is discussed in the Ford
Truck Body Builders Layout Book, found at
www.fleet.ford.com/truckbbas.
Note: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. Depending on the level of
auxiliary horsepower draw and for how long, vehicle and surrounding
environmental conditions, and other factors, this can contribute to
elevated transmission fluid temperatures and resultant accelerated fluid
aging, fuel vapor over-pressurization, and other concerns. Ford trucks are
fully qualified for stationary PTO operation for 10 minutes or less of
continuous operation. For extended duration stationary PTO operation
(beyond 10 minutes) diesel engine is recommended, and further consult
your aftermarket PTO installer.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine.

IN CALIFORNIA (U.S. ONLY)
California Civil Code Section 1793.2(d) requires that, if a manufacturer
or its representative is unable to repair a motor vehicle to conform to the
vehicle’s applicable express warranty after a reasonable number of
attempts, the manufacturer shall be required to either replace the
vehicle with one substantially identical or repurchase the vehicle and
reimburse the buyer in an amount equal to the actual price paid or
payable by the consumer (less a reasonable allowance for consumer
use). The consumer has the right to choose whether to receive a refund
or replacement vehicle.
California Civil Code Section 1793.22(b) presumes that the manufacturer
has had a reasonable number of attempts to conform the vehicle to its
applicable express warranties if, within the first 18 months of ownership
of a new vehicle or the first 29,000 km (18,000 miles), whichever occurs
first:
1. Two or more repair attempts are made on the same nonconformity
likely to cause death or serious bodily injury OR
2. Four or more repair attempts are made on the same nonconformity (a
defect or condition that substantially impairs the use, value or safety of
the vehicle) OR

How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
andsymbol will
illuminate.
•TheService Engine Soon
indicator light will illuminate.
If the engine reaches a preset
over-temperature condition, the engine will automatically switch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
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 a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.

Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
“Regular”unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as“Regular”that
are sold with octane ratings of 86 or lower in high altitude areas.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your dealer or a qualified
service technician to prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of unleaded gasoline.
“Premium”unleaded gasoline is not recommended for vehicles designed
to use“Regular”unleaded gasoline because it may cause these problems
to become more pronounced. If the problems persist, see your dealer or
a qualified service technician.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-wide Fuel Charter.
Cleaner air
Ford endorses the use of reformulated“cleaner-burning”gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.

Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
•Idling for long periods of time (greater than one minute) may waste
fuel.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).

Temperature A B C
The temperature grades are A (the highest), B and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.
Glossary of tire terminology
•Tire label:A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.
•Tire Identification Number (TIN):A number on the sidewall of
each tire providing information about the tire brand and
manufacturing plant, tire size and date of manufacturer.
•Inflation pressure:A measure of the amount of air in a tire.
•Standard load:A class of P-metric or Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing
the inflation pressure beyond this pressure will not increase the tires
load carrying capability.
•Extra load:A class of P-metric or Metric tires designed to carry a
heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].
Increasing the inflation pressure beyond this pressure will not increase
the tires load carrying capability.
•kPa:Kilopascal, a metric unit of air pressure.
•PSI:Pounds per square inch, a standard unit of air pressure.
