2004 FORD SUPER DUTY ECU

The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated until the
parking brake is released.
Pull the right side of the release
lever to release the parking brake;
the release lever pulls at an angle
toward the driver’s door. To prevent
the pedal from releasing too quickly,
place your left foot on the parking
brake pedal, then pull the release
lever, making sure the pedal fully
releases. You may want to pull the
release lever again to make sure the
parking brake is full released.
Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual transmission).
Note:If your vehicle is equipped with a manual transmission, the engine
may be required to run while power accessories operate and the parking
brake is set. It is recommended that wheel chocks be used during this
operation.
If you’re 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.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few 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).

If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.

The following steps apply to all vehicles:
19. Remove the jack and fully
tighten the lug nuts in the order
shown.
20. Stow the flat tire. Refer to
Stowing the spare tireif the
vehicle is equipped with a spare tire
carrier.
Note:Do not stow Harley-Davidson
flat tire and wheel using the spare
tire winch mechanism; store the flat
in the bed of the truck.
21. Stow the jack, jack handle and lug wrench. Make sure the jack is
securely fastened so it does not rattle when driving.
22. Unblock the wheels.
Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing in the direction
specified on the Tire Changing Instructions located with the jack
hardware.
2. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
3. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your dealer for
assistance at your earliest convenience.

REPORTING SAFETY DEFECTS (U.S. ONLY)
If you believe that your vehicle has
a defect which could cause a crash
or could cause injury or death, you
should immediately inform the National Highway Traffic Safety
Administration (NHTSA) in addition to notifying Ford Motor Company.
If NHTSA receives similar complaints, it may open an investigation, and
if it finds that a safety defect exists in a group of vehicles, it may order a
recall and remedy campaign. However, NHTSA cannot become involved
in individual problems between you, your dealer, or Ford Motor
Company.
To contact NHTSA, you may either call the Auto Safety Hotline toll-free
at 1–800–424–9393 (or 366–0123 in the Washington D.C. area) or write
to:
NHTSA
400 Seventh Street
U.S. Department of Transportation
Washington, D.C. 20590
You can also obtain other information about motor vehicle safety from
the Hotline.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16–A2.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5°C (40°
F), use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park) (automatic transmission) or 1 (First) (manual transmission).
4. Open the hood. Protect yourself from engine heat.
