2003 FORD SUPER DUTY power steering

Each daybefore you drive, check
your tires. If one looks lower than
the others, use a tire gauge to check
pressure of all tires, and adjust if
required. Check tire pressure with a
tire gauge everyfew weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor a vehicle which is
overloaded.
Periodicallyinspect the tire treads and remove stones, nails, glass or
other objects that maybe wedged in the tread grooves. Check for holes
or cuts that maypermit air leakage from the tire and make necessary
repairs.
Inspect the tire side walls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire demounted and inspected
in case it needs to be repaired or replaced.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide both reasonablysafe, predictable performance
whether loaded or emptyand durable load carrying capability. For this
reason, Ford Motor Companystronglyrecommends that you do not make
modifications such as adding or removing parts (such as lift kits or
stabilizer bars) or byusing replacement parts not equivalent to the
original factoryequipment.
Anymodifications to a vehicle that raise the center of gravitycan make
it more likelythe vehicle will roll over as a result of a loss of control.
Ford Motor Companyrecommends that caution be used with anyvehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properlymayvoid the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adverselyaffect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavyoff-road usage.
POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED)
Some vehicles maybe equipped with Power Take Off (PTO) capability.
These vehicles have a special transmission case, internal components and
calibration for PTO usage.

The fuse panel is located below and to the left of the steering wheel by
the brake pedal. Remove the panel cover to access the fuses.
To remove the fuse panel cover,
turn the panel fasteners

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•graduallydecrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowlymove to a safe place on the side of the road.
The use of tire sealants is not recommended and may
compromise the integrityof your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
Spare tire information
Your vehicle maybe equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire maybe used on the
spare.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Use of such a tire
could result in damage to driveline components and an increased risk
of loss of vehicle control, vehicle rollover, personal injuryor death.
If your vehicle is equipped with a tire pressure monitoring
system, refer to Tire Pressure Monitoring System (if equipped)
in the Maintenance and specifications section for important information
before changing your tires. If the tire pressure monitoring system
becomes damaged, it will no longer function.

•Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling (if equipped)
If the engine coolant supplyis depleted, this feature allows the vehicle to
be driven temporarilybefore incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
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 automaticallyswitch 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 completelyshut down, causing steering and braking effort to
increase.

CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid.
Refer to the scheduled maintenance
guide for the service interval
schedules. If adding fluid is
necessary, use only MERCON
AT F.
Check the fluid level when it is at ambient temperature, 20° – 80° F (-7°
– 25° C):
1. Check the fluid level on the dipstick. It should be between the arrows
in the FULL COLD range. Do not add fluid if the level is within this
range.
2. If the fluid level is low, start the engine.
3. While the engine idles, turn the steering wheel left and right several
times.
4. Turn the engine off.
5. Recheck the fluid level on the dipstick. Do not add fluid if the level is
between the arrows in the FULL COLD range.
6. If the fluid is low, add fluid in small amounts, continuouslychecking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir.
BRAKE FLUID RESERVOIR
The fluid level will drop slowlyas
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the “MAX” line
that do not trigger the brake system
warning lamp 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 your brake system could be compromised, seek
service from your dealer immediately.

1Your vehicle’s rear axle(s) maybe filled with a synthetic lubricant that
mayrequire a lubricant change. Refer to the scheduled maintenance
guide. Axle lubricant quantities should not need to be checked unless a
leak is suspected, service is required or the axle assemblyhas been
submerged in water. The axle lubricant should be changed anytime the
rear axle has been submerged in water.
