•For routine cleaning, use Motorcraft Detail Wash (ZC-3–A).
•If tar or grease spots are present, use Motorcraft Bug and Tar
Remover (ZC-42).
WINDOWS AND WIPER BLADES
The windshield, rear and side windows and the wiper blades should be
cleaned regularly. If the wipers do not wipe properly, substances on the
vehicle’s glass or the wiper blades may be the cause. These may include
hot wax treatments used by commercial car washes, tree sap, or other
organic contamination. To clean these items, please follow these tips:
•The windshield, rear windows and side windows may be cleaned with
a non-abrasive cleaner such as Motorcraft Ultra Clear Spray Glass
Cleaner (ZC-23), available from your dealer.
•Do not use abrasives, as they may cause scratches.
•Do not use fuel, kerosene, or paint thinner to clean any parts.
•Wiper blades can be cleaned with isopropyl (rubbing) alcohol or
windshield washer solution. Be sure to replace wiper blades when they
appear worn or do not function properly.
INSTRUMENT PANEL AND CLUSTER LENS
Clean the instrument panel with a damp cloth, then dry with a dry cloth.
•Avoid cleaners or polish that increase the gloss of the upper portion of
the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
•Be certain to wash or wipe your hands clean if you have been in
contact with certain products such as insect repellent and suntan
lotion in order to avoid possible damage to the painted surfaces.
INTERIOR TRIM
•Clean the interior trim areas with a damp cloth, then dry by wiping
with a dry, soft, clean cloth.
•Do not use household or glass cleaners as these may damage the
finish.
INTERIOR
For fabric, carpets, cloth seats and safety belts:
•Remove dust and loose dirt with a vacuum cleaner.
•Remove light stains and soil with Motorcraft Professional Strength
Carpet and Upholstery Cleaner (ZC-54).

Conditions
•Carrying unnecessary weight may reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Flat terrain driving improves fuel economy over hilly roads.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the accelerator.
•Close windows for highway driving.
DIESEL PARTICULATE FILTER (DPF)
Your vehicle is equipped with a diesel particulate filter (DPF), as part of
the after-treatment exhaust system, to trap soot and other large particles
produced by the engine combustion process. The soot that accumulates
in the filter must be periodically reduced to ash to prevent excessive
exhaust restriction. The soot reduction process, also known as “filter
regeneration,” is generally performed automatically by your engine and
after-treatment system.
The normal operating temperature of the exhaust system is very
high. Never work around, or attempt to repair, any part of the
exhaust system until it has cooled. Use special care when working
around the diesel particulate filter. The DPF heats up to a high
temperature after only a short period of engine operation, and can
remain hot even after the engine is turned off. Failure to follow these
instructions may result in personal injury.
Diesel particulate filter regeneration (Caterpillar engine only)
DPF regeneration requires no operator interaction and may occur at any
time. A small increase in engine sound-level during filter regeneration is
normal and should be no reason for concern.
A separate fuel injector/nozzle, which requires periodic cleaning, is used
in the regeneration process. Refer to Caterpillar’sOperation and
Maintenance Manualfor details regarding cleaning requirements.

When installing wheel balance weights, they must be mounted on the
dome-side of the wheel only. Failure to do so may result in loss of wheel
weight and/or damage to brakes or wheels.
Important:Remember to replace the wheel air valves when the road
tires are replaced at the end of their useful life.
Oil lubricated front wheel bearings
During normal vehicle duty cycle, the lube and air inside the hub/wheel
cavity expands and if not vented, causes pressure build-up that could
cause accelerated seal wear.
There are two venting methods:
•a slit or small hole in the rubber check vent or
•the window
You can use either of these methods to prevent pressure build-up.
Normal maintenance
Over a period of time, if not routinely cleaned, a slight film of oil can
collect dirt around the rubber fill plug and face, which could appear to
be a leak. Routine cleaning ensures that the lube level can be easily
observed through the clear window as intended. In situations where the
window is clean on the outside but discolored on the inside, the lube
level may be checked by inserting a finger through the rubber check
vent hole.
The specified lube level for a clear window type hubcaps is from the
minimum line to + 5/16 inch above the minimum line.
If the lube level should suddenly drop dramatically below the minimum
level, see theWorkshop Manualfor diagnostic procedure.
Installation, tightening and alignment
When installing wheels, be certain that the threads on studs and nuts are
clean to permit correct torque. The mounting surfaces of rims, wheels,
spacer rings and clamps must be free of dirt, rust, lubricants or damage.
Use a wire brush to clean the mounting contact surfaces. Do not use
lubricant on threads.
After the rim or wheel has been properly tightened, it should be checked
for alignment. Rotate the wheel with a piece of chalk attached to a
steady, firm surface, and placed to just barely clear the outside surface of
the tire bead seat. This procedure will point out the high spot. A high
spot does not necessarily mean that the lug nuts have been unevenly
tightened. This condition or misalignment could be caused by a bent
wheel.
