2003 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS tire pressure

If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage. Have the fluid checked and, if
water is found, replace the fluid.
VEHICLE LOADING
Your vehicle’s load capacity is designed by weight, not volume, so you
cannot necessarily use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire, rim sizes and inflation
pressures are specified for your vehicle on the Safety Compliance
Certification Label. A Certification Label was supplied by Ford Motor
Company to the Motorhome Manufacturer. The manufacturer uses this
information and supplies a Certification Label which is located inside the
vehicle to the left of the driver.
Before loading a vehicle, familiarize yourself with the following terms:
•Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
•Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
•GVWR (Gross Vehicle Weight Rating):Maximum permissible total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Certification
Label, located near the driver’s seat or on the driver’s door pillar.
•GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Certification Label, located near the driver’s seat or on the driver’s
door pillar.
•GCWR (Gross Combined Weight Rating):Maximum permissible
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer.

ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels or covers are coated with a clearcoat paint finish. In
order to maintain their shine:
•Clean weekly with Motorcraft Wheel and Tire Cleaner (ZC-37–A),
which is available from your dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Ford Extra Strength Tar and Road Oil
Removal (B7A-19520–AA), available from your dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
UNDERBODY
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.

SERVICING YOUR TIRES
Tire inflation information
This vehicle is equipped with a tire that is an all-steel radial. All-steel
radial tires utilize steel cords in the sidewalls, and also require increased
inflation pressures of up to 95 psi (refer to the Certification Label for
recommended tire pressure). As such, they cannot be treated like normal
light truck tires. Tire service, including adjusting tire pressure, must be
performed by personnel trained, supervised and equipped according to
Federal Occupational Safety and Health Administration (OSHA)
regulations. For example, during any procedure involving tire inflation,
the technician or individual must utilize a remote inflation device, and
insure that all persons are clear of the trajectory area.
WARNINGAn inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly for
inspection. Do not attempt to add air to tires or replace tires or wheels
without first taking precautions to protect persons and property.
Tire rotation
Because your vehicle’s tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
Your front tires should be rotated from side to side. If the spare tire is
used in the rotation, the pattern should be; left front to right front; right
front to the spare and the spare to left front.
Do not rotate the dual tires.
