Trailer ABS brake system (if
equipped):Illuminates briefly when
the engine is powered-up and only
when a PLC trailer or a PLC
diagnostic tool is connected. If the
light remains on after the vehicle is started, continues to flash or fails to
illuminate, have the system serviced immediately.
Parking brake warning:
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. Also
illuminates when the parking brake
is engaged. If the brake warning
lamp does not illuminate at these
times, seek service immediately.
Safety belt:Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Check trans (Allison automatic
transmission):The lamp will
illuminate for several seconds after
the ignition is turned to the ON
position. Illumination of this light indicates that a problem has been
detected and shifting may be restricted. Depending upon the severity of
the problem, the read-out digit on the shifter display may be blank.
Operation may continue in order to reach service assistance. The ECU
may not respond to shift selector requests, since operating limitations
are being placed on the transmission, i.e. upshifts and downshifts may be
restricted. Direction changes will not occur.
Refer to the Transmission Operator’s Manual for more information.
Range inhibit:Illuminates when
the transmission is not engaged in
the selected gear. The warning light
will go off when the gearshift lever
is adjusted in to the appropriate gear.
Refer to the Transmission Operator’s Manual for more information.

CD/CD PLAYER CARE
Do:
•Handle discs by their edges only. Never touch the playing surface.
•Inspect discs before playing. Clean only with an approved CD cleaner
and wipe from the center out.
Don’t:
•Expose discs to direct sunlight or heat sources for extended periods
of time.
•Insert more than one disc into each slot of the CD changer magazine.
•Clean using a circular motion.
CD units are designed to play commercially pressed 12 cm (4.75
in) audio compact discs only. Due to technical incompatibility,
certain recordable and re-recordable compact discs may not
function correctly when used in Ford CD players. Irregular
shaped CDs, CDs with a scratch protection film attached, and CDs
with homemade paper (adhesive) labels should not be inserted
into the CD player. The label may peel and cause the CD to
become jammed. It is recommended that homemade CDs be
identified with permanent felt tip marker rather than adhesive
labels. Ball point pens may damage CDs. Please contact your
dealer for further information.
AUDIO SYSTEM WARRANTY AND SERVICE
Refer to theWarranty Guidefor audio system warranty information. If
service is necessary, see your dealer or qualified technician.

Air brakes - desiccant air dryer
Inspect for moisture in the air system by opening reservoirs, drain cocks
or valves and checking for presence of water. The presence of small
amounts of water due to condensation is normal and should not be
considered as an indication that the dryer is not functioning properly.
The desiccant cartridge should be replaced or rebuilt when it has been
determined that the desiccant is contaminated and does not have
adequate water absorption capacity. The desiccant change interval may
vary; it is generally recommended that the desiccant be replaced every
12 months (yearly). If experience has shown that extended or shortened
life has resulted for a particular installation, then the yearly interval can
be increased or decreased accordingly.
Hydraulic brakes - general inspection and adjustment
A regular schedule for periodic cleaning, lubrication, adjustment and
inspection should be established based on the type of vehicle operation.
It is difficult to predetermine an exact maintenance interval (time or
mileage), since vehicles will be used in a wide variety of applications and
conditions. If you are uncertain of the proper schedule and procedures
for your vehicle, contact your dealer.
Inspect the brake lining every maintenance interval. Establish inspection
intervals that provide for lining replacement before damage to the disc
occurs. Excessive lining wear may expose the backing plate to the disc
causing scoring of the disc faces.
This inspection should be performed by a qualified technician and must
be in accordance with instructions provided by the service manual.
Note:Hydraulic brake system are power assisted. Braking capabilities
will be greatly reduced without engine assist.
Hydraulic brakes - fluid level
Fluid level should be at the bottom edge of the ring on each reservoir fill
port. Do not fill the master cylinder to the top of the reservoir.
Note:If brake fluid requires attention to maintain a proper master
cylinder level, this is an indication of either severe operation (pad wear)
or fluid system leakage. A more frequent and thorough brake inspection
will be required.

Engine oil and filter recommendations—6.0L Power Stroke engine
To help achieve proper engine performance and durability, it is important
that you:
•Use only engine lubricating oils and oil filters of the proper quality.
•Change the engine oil and filterno laterthan the recommended
service interval. Refer to the general maintenance information section
for the appropriate intervals for changing the engine oil and filter.
•Change your engine oil and filter more frequently if your vehicle
operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or short driving distances.
Diesel engines require specially formulated oil to resist contamination.
Proper quality oils also provide maximum efficiency of the crankcase
ventilation system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171–C or API Service
categories CI-4 or CI-4/SL. If CI-4 oil is not available, CH-4 is acceptable.
Diesel engine oils with improved fuel economy properties (energy
conserving) are currently available. If you use an energy conserving oil,
be sure it meets Ford specification WSS-M2C171–D or API service
category designation CI-4/SL and is of the proper viscosity grade for the
temperature range in which you expect to operate your vehicle. Some
energy conserving oils do not meet the requirements necessary for your
diesel engine.

LUBRICATION AND MAINTENANCE INTERVALS
New vehicles are lubricated at the factory. After the vehicle is placed in
operation, regular lubrication intervals, based on the type of service and
road conditions, should be established. Thorough lubrication at the
specified intervals will insure outstanding life cycle value and will reduce
overall expense.
The lubrication intervals specified should be performed at whatever
interval occurs first, whether it is months, kilometer (miles) or hours.
Only lubricants of superior quality, such as Motorcraft lubricants, should
be used. The use of inferior products will reduce the service life of the
vehicle or result in failure of its components.
Unless otherwise specified, never add lubricant unless it is the same
grade as that which is already being used. If the grade is not known or
not available, drain, flush and refill with new lubricant.
The interval between lubrication periods, oil changes, etc. depends
entirely upon operating conditions. The loads carried, speeds, road and
weather conditions all contribute to the frequency of lubrication periods.
In some types of operation, and where operating conditions are
extremely severe (such as in deep water, mud or unusually dusty
conditions), the vehicle may require lubrication after every 24 hours of
operation.
Maintenance intervals
Maintenance intervals are provided for three types of general vehicle
environments: On-Highway, City and Severe Service. In all applications,
the actual interval is determined by monitoring kilometers (miles) and
time and when the engine is due for an oil change. When the engine oil
change is required prior to the truck lubrication interval, it is
recommended that the lubrication be performed at the same time in
order to reduce your vehicle’s time out of service.
•On-Highway:96,000 km (60,000 miles) or more annually.
•City:95,000 km (59,000 miles) or less annually.
•Severe Service:32,000 km (20,000 miles) or less annually on/off
road in dirty conditions.
