Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originally provided by Ford Motor Company because it can affect
the safety and performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover, and/or serious
personal injury or death.
AWD vehicles are equipped with tires designed to provide for safe ride
and handling capability.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design and load-carrying capacity. If you have questions regarding
tire replacement, see an authorized Ford or Lincoln Mercury dealer.
If you nevertheless decide to equip your AWD for off-road use with tires
larger than what Ford Motor Company recommends, you should not use
these tires for highway driving.
If you use any tire/wheel combination not recommended by Ford Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure as well as the increased
risk of loss of vehicle control.
Do not use ªaftermarket lift kitsº or other suspension modifications,
whether or not they are used with larger tires and wheels.
These ªaftermarket lift kitsº could adversely affect the vehicle's handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford Motor Company recommended pressure
even if it is less than the maximum pressure allowed for the tire.

WASHING THE EXTERIOR
Wash your vehicle regularly with cool or lukewarm water and a neutral
Ph shampoo, such as Motorcraft Detail Wash (ZC-3±A), which is available
from your dealer.
²Never use strong household detergents or soap, such as dish washing
or laundry liquid. These products can discolor and spot painted
surfaces.
²Never wash a vehicle that is ªhot to the touchº or during exposure to
strong, direct sunlight.
²Always use a clean sponge or carwash mitt with plenty of water for
best results.
²Dry the vehicle with a chamois or soft terry cloth towel in order to
eliminate water spotting.
²It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
²Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle's
paintwork and trim over time.
²Remove any exterior accessories, such as antennas, before entering a
car wash.
²Suntan lotions and insect repellents can damage any painted
surface; if these substances come in contact with your vehicle,
wash off as soon as possible.
²If your vehicle is equipped with running boards, do not use
rubber, plastic and vinyl protectant products on the running
board surface, as the area may become slippery.
WAXING
Applying a polymer paint sealant to your vehicle every six months will
assist in reducing minor scratches and paint damage.
²Wash the vehicle first.
²Do not use waxes that contain abrasives.
²Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will ªgrayº or stain the parts over time.

PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle's color.
Take your color code (printed on a sticker in the driver's door jam) to
your dealer to ensure you get the correct color.
²Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
²Always read the instructions before using the products.
ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels and wheel covers are coated with a clearcoat paint
finish. In order to maintain their shine:
²Clean 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.
²Never apply any cleaning chemical to hot or warm wheel rims or
covers.
²Some 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.
²Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
²To remove tar and grease, use Motorcraft Bug and Tar Remover
(ZC-42), 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:
²Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
²Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
²Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.

CLEANING THE CLIMATE CONTROLLED SEATS (IF EQUIPPED)
Remove dust and loose dirt with a whisk broom or a vacuum cleaner.
Remove fresh spots immediately. Clean the seat with a damp cloth, using
a mild soap and water solution, if necessary.
LEATHER SEATS
Your leather seating surfaces have a clear, protective coating over the
leather.
²To clean, use a soft cloth with Motorcraft Deluxe Leather and Vinyl
Cleaner (ZC-11±A). Dry the area with a soft cloth.
²To help maintain its resiliency and color, use the Motorcraft Deluxe
Leather Care Kit (ZC-11±D), available from your authorized dealer.
²Do not use household cleaning products, alcohol solutions, solvents or
cleaners intended for rubber, vinyl and plastics, or oil/petroleum-based
leather conditioners. These products may cause premature wearing of
the clear, protective coating.
Note:In some instances, color or dye transfer can occur when wet
clothing comes in contact with leather upholstery. If this occurs, the
leather should be cleaned immediately to avoid permanent staining.
INTERIOR TRIM
²Clean the interior trim areas with a damp cloth, then dry by wiping
with a dry, soft, clean cloth.
²Do not use household or glass cleaners as these may damage the
finish.
UNDERBODY
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.

space-saver or temporary use spare tires, tires with nominal rim
diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford to give you the following
information about tire grades exactly as the government has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire's ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B and C, representing the
tire's resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
Maintenance and Specifications
297

The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.
Glossary of tire terminology
²Tire label:A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.
²Tire Identification Number (TIN):A number on the sidewall of
each tire providing information about the tire brand and
manufacturing plant, tire size and date of manufacturer.
²Inflation pressure:A measure of the amount of air in a tire.
²Standard load:A class of P-metric or Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing
the inflation pressure beyond this pressure will not increase the tires
load carrying capability.

a maximum speed capability over 299 km/h (186 mph), tire
manufacturers always use the letters ZR.
8.U.S. DOT Tire Identification Number (TIN):This begins with the
letters ªDOTº and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The
numbers in between are marketing codes used at the manufacturer's
discretion. This information is used to contact customers if a tire defect
requires a recall.

specified indoor laboratory test wheel.
13.Maximum Permissible Inflation Pressure:Tire manufactures
maximum permissible pressure and/or the pressure at which the
maximum load can be carried by the tire. This pressure is normally
higher than the manufacturer's recommended cold inflation pressure
which can be found on either the tire label or certification label which is
located on the structure by the trailing edge of the driver's door or the
edge of the driver's door. The cold inflation pressure should never be set
lower than the recommended pressure on the label.
