•

Use a spray with a 40 degree wide
spray angle pattern.

•

Keep the nozzle at a 12 in (305 mm)
distance and 90 degree angle to your
vehicle's surface.

Note:

Holding the pressure washer nozzle

at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.

Underbody

Regularly clean the underside of your
vehicle using water. Keep body and door
drain holes free of debris or foreign
material.

Under Hood

For removing black rubber marks from
under the hood we recommend Motorcraft
Wheel and Tire Cleaner or Motorcraft Bug
and Tar Remover.

WAXING

Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.

When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.

•

Use a quality wax that does not contain
abrasives.

•

Follow the manufacturer’s instructions
to apply and remove the wax.

•

Apply a small amount of wax in a
back-and-forth motion, not in circles.

•

Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.

•

Roof racks.

•

Bumpers.

•

Grained door handles.

•

Side moldings.

•

Mirror housings.

•

Windshield cowl area.

•

Do not apply wax to glass areas.

•

After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.

CLEANING THE 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 on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.

Note:

If your vehicle has an engine cover

remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.

264

Vehicle Care

•

Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.

•

Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.

•

Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.

CLEANING THE WINDOWS AND
WIPER BLADES

Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.

To clean the windshield and wiper blades:

•

Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.

•

For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.

•

Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.

Note:

Do not use razor blades or other

sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.

CLEANING THE INTERIOR

WARNING:

Do not use cleaning

solvents, bleach or dye on the vehicle's
seatbelts, as these actions may weaken
the belt webbing.

WARNING:

On vehicles equipped

with seat-mounted airbags, do not use
chemical solvents or strong detergents.
Such products could contaminate the
side airbag system and affect
performance of the side airbag in a crash.

For fabric, carpets, cloth seats and seats
equipped with side airbags:

•

Remove dust and loose dirt with a
vacuum cleaner.

•

Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.

•

If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.

•

If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.

•

Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.

Mirrors

Do not clean the housing or glass of any
mirror with harsh abrasives, fuel or other
petroleum or ammonia-based cleaning
products.

265

Vehicle Care

CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS

WARNING:

Do not use chemical

solvents or strong detergents when
cleaning the steering wheel or
instrument panel to avoid contamination
of the airbag system.

Note:

Follow the same procedure as

cleaning leather seats for cleaning leather
instrument panels and leather interior trim
surfaces.

Clean the instrument panel and cluster
lens with a clean, damp and soft cloth,
then use a clean, dry and soft cloth to dry
these areas.

•

Avoid cleaners or polishes that increase
the gloss of the upper portion of the
instrument panel. The dull finish in this
area helps protect you from
undesirable windshield reflection.

•

Do not use any household cleaning
products or glass cleaners as these
may damage the finish of the
instrument panel, interior trim and
cluster lens.

•

Wash or wipe your hands clean if you
have been in contact with certain
products such as insect repellent and
suntan lotion to avoid possible damage
to the interior painted surfaces.

•

Do not allow air fresheners and hand
sanitizers to spill onto interior surfaces.
If a spill occurs, wipe off immediately.
Your warranty may not cover these
damages.

If a staining liquid like coffee or juice has
been spilled on the instrument panel or on
interior trim surfaces:

Wipe up spilled liquid using a clean,
soft cloth as quickly as possible.

2. Use Motorcraft Premium Leather and

Vinyl Cleaner or a commercially
available leather cleaning product for
automotive interiors. Test any cleaner
or stain remover on an inconspicuous
area.

3. Alternatively, wipe the surface with a

clean, soft cloth and a mild soap and
water solution. Dry the area with a
clean, soft cloth.

4. If necessary, apply more soap and

water solution or cleaning product to
a clean, soft cloth and press it onto the
soiled area. Allow this to set at room
temperature for 30 minutes.

5. Remove the soaked cloth, then with a

clean, damp cloth, use a rubbing
motion for 60 seconds on the soiled
area.

6. Dry the area with a clean, soft cloth.

REPAIRING MINOR PAINT
DAMAGE

Authorized dealers have touch-up paint to
match your vehicle’s color. Your vehicle
color code is printed on a sticker on the
front, left-hand side door jamb. Take your
color code to your authorized dealer to
make sure you get the correct color.

Before repairing minor paint damage, use
a cleaner to remove particles such as bird
droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout.

Read the instructions before using cleaning
products.

CLEANING THE WHEELS

Regularly clean them with a wheel
cleaner. We recommend that you use
Ford approved wheel cleaner if
available.

266

Vehicle Care

2. Remove dirt and brake dust with a

sponge.

3. Remove tar and grease with a bug and

tar remover. We recommend that you
use Ford approved bug and tar remover
if available.

4. Thoroughly rinse the wheels with water

after cleaning.

If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before doing so. This
reduces the risk of corrosion of the brake
discs, brake pads and linings.

Do not clean the wheels when they are hot.

Note:

Some car washes could damage

wheel rims and covers.

Note:

Using non-recommended cleaners,

harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers.

VEHICLE STORAGE

If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.

We engineer and test all motor vehicles
and their components for reliable, regular

every 15 days to lubricate working parts
and prevent corrosion.

Removing Vehicle From Storage

When your vehicle is ready to come out of
storage, do the following:

•

Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.

•

Check windshield wipers for any
deterioration.

•

Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.

•

Check the exhaust for any foreign
material that may have collected
during storage.

•

Check tire pressures and set tire
inflation per the Tire Label.

•

Check brake pedal operation. Drive
your vehicle 15 ft (4.5 m) back and
forth to remove rust build-up.

•

Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.

•

If you remove the battery, clean the
battery cable ends and check for
damage.

Contact an authorized dealer if you have
any concerns or issues.

Glossary of Tire Terminology

Tire label:

A label showing the

original equipment tire sizes,
recommended inflation pressure
and the maximum weight the
vehicle can carry.

Tire Identification Number:

number on the sidewall of each
tire providing information about
the tire brand and manufacturing
plant, tire size and date of
manufacture. Also referred to as
DOT code.

Inflation pressure:

A measure

of the amount of air in a tire.

Standard load:

A class of

P-metric or Metric tires designed
to carry a maximum load at set
pressure. For example: For
P-metric tires 35 psi (241 kPa) and
for Metric tires 36 psi (248 kPa).
Increasing the inflation pressure
beyond this pressure does not
increase the tire’s load carrying
capability.

Extra load:

A class of P-metric

or Metric tires designed to carry a
heavier maximum load at 42 psi
(290 kPa). Increasing the inflation
pressure beyond this pressure
does not increase the tire’s load
carrying capability.

kPa:

Kilopascal, a metric unit of

air pressure.

PSI:

Pounds per square inch, a

standard unit of air pressure.

Cold tire pressure:

The tire

pressure when the vehicle has
been stationary and out of direct
sunlight for an hour or more and
prior to the vehicle being driven for
1 mi (1.6 km).

Recommended inflation

pressure:

The cold inflation

pressure is found on the Safety
Compliance Certification Label,
located in the driver's door jam.

Bead area of the tire:

Area of

the tire next to the rim.

Sidewall of the tire:

Area

between the bead area and the
tread.

Tread area of the tire:

Area of

the perimeter of the tire that
contacts the road when mounted
on the vehicle.

Rim:

The metal support (wheel)

for a tire or a tire and tube
assembly upon which the tire
beads are seated.

Information Contained on the
Tire Sidewall

Both United States and Canada
Federal regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case
of a recall.

Traction:

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.

Temperature:

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.

Maximum Inflation

Indicates the tire

manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle manufacturer's
recommended cold inflation
pressure which can be found on
the Safety Compliance
Certification Label. The cold
inflation pressure should never be
set lower than the recommended
pressure on the vehicle label.

The tire suppliers may have
additional markings, notes or

16:

Indicates the wheel or rim

diameter in inches. If you change
your wheel size, you have to
purchase new tires to match the

Inflating Your Tires

Safe operation of your vehicle
requires that your tires are
properly inflated. Remember that
a tire can lose up to half of its air
pressure without appearing flat.

Every day before 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.

At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge (including spare, if
equipped). Inflate all tires to the
inflation pressure recommended
by Ford Motor Company.

You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
may be inaccurate. Ford
recommends the use of a digital
or dial-type tire pressure gauge
rather than a stick-type tire
pressure gauge.

Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns

WARNING:

Under-inflation

is the most common cause of
tire failures and may result in
severe tire cracking, tread
separation or blowout, with
unexpected loss of vehicle
control and increased risk of
injury. Under-inflation increases
sidewall flexing and rolling
resistance, resulting in heat
buildup and internal damage to
the tire. It also may result in
unnecessary tire stress, irregular
wear, loss of vehicle control and
accidents. A tire can lose up to
half of its air pressure and not
appear to be flat!

Always inflate your tires to the
Ford recommended inflation
pressure even if it is less than the
maximum inflation pressure
information found on the tire. The
Ford recommended tire inflation
pressure is found on the Safety
Compliance Certification Label or
Tire Label. Failure to follow the tire
pressure recommendations can
cause uneven treadwear patterns
and adversely affect the way your
vehicle handles.

274

Wheels and Tires

Maximum Inflation Pressure

the tire manufacturer's maximum
permissible pressure and 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 the Safety
Compliance Certification Label or
Tire Label. The cold inflation
pressure should never be set lower
than the recommended pressure
on the Safety Compliance
Certification Label or Tire Label.

When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of
1 psi (7 kPa) in inflation pressure.
Check your tire pressures
frequently and adjust them to the
proper pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.

To check the pressure in your
tire(s):

1. Make sure the tires are cool,

meaning they are not hot from
driving even a mile.

Note:

If you are checking tire

pressure when the tire is hot, for
example, driven more than 1 mi
(1.6 km), never bleed or reduce air
pressure. The tires are hot from
driving and it is normal for
pressures to increase above
recommended cold pressures. A
hot tire at or below recommended
cold inflation pressure could be
significantly under-inflated.

Note:

If you have to drive a

distance to get air for your tire(s),
check and record the tire pressure
first and add the appropriate air
pressure when you get to the
pump. It is normal for tires to heat
up and the air pressure inside to go
up as you drive.

2. Remove the cap from the valve

on one tire, then firmly press
the tire gauge onto the valve
and measure the pressure.

3. Add enough air to reach the

recommended air pressure.

Note:

If you overfill the tire, release

air by pressing on the metal stem
in the center of the valve. Then
recheck the pressure with your tire
gauge.

4. Replace the valve cap.
5. Repeat this procedure for each

tire, including the spare.

275

Wheels and Tires

Note:

Some spare tires operate at

a higher inflation pressure than the
other tires. For T type mini-spare
tires, see the Dissimilar spare wheel
and tire assembly information for
a description. Store and maintain
at 60 psi (412 kPa). For full-size
and dissimilar spare tires, see the
Dissimilar spare wheel and tire
assembly information for a
description. Store and maintain at
the higher of the front and rear
inflation pressure as shown on the
Safety Compliance Certification
Label or Tire Label.

6. Visually inspect the tires to

make sure there are no nails or
other objects embedded that
could poke a hole in the tire
and cause an air leak.

7. Check the sidewalls to make

sure there are no gouges, cuts
or bulges.

Tire Inflation Information

WARNING:

An inflated tire

and rim can be very dangerous
if improperly used, serviced or
maintained. To reduce the risk
of 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.

All tires with Steel Carcass Plies
(if equipped):

This type of tire utilizes steel cords
in the sidewalls. 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
regulations. For example, during
any procedure involving tire
inflation, the technician or
individual must utilize a remote
inflation device, and ensure that
all persons are clear of the
trajectory area.

Inspecting Your Tires and
Wheel Valve Stems

Periodically inspect the tire treads
for uneven or excessive wear and
remove objects such as stones,
nails or glass that may be wedged
in the tread grooves. Check the tire
and valve stems for holes, cracks,
or cuts that may permit air
leakage and repair or replace the
tire and replace the valve stem.
Inspect the tire sidewalls for
cracking, cuts, bruises and other
signs of damage or excessive

wear. If internal damage to the tire
is suspected, have the tire
demounted and inspected in case
it needs to be repaired or replaced.
For your safety, tires that are
damaged or show signs of
excessive wear should not be used
because they are more likely to
blow out or fail.

278

Wheels and Tires

Improper or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all your
tires, including the spare,
frequently, and replace them if
one or more of the following
conditions exist:

Tire Wear

E142546

When the tread is worn down to
one sixteenth of an inch (2
millimeters), tires must be
replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or wear bars, which
look like narrow strips of smooth
rubber across the tread appears
on the tire when the tread is worn
down to one sixteenth of an inch
(2 millimeters).

When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.

Damage

Periodically inspect the tire treads
and sidewalls for damage, such
as bulges in the tread or sidewalls,
cracks in the tread groove and
separation in the tread or sidewall.
If damage is observed or
suspected have the tire inspected
by a tire professional. Tires can be
damaged during off-road use, so
inspection after off-road use is
also recommended.

Age

WARNING:

Tires degrade

over time depending on many
factors such as weather, storage
conditions, and conditions of use
(load, speed, inflation pressure)
the tires experience throughout
their lives.

WARNING:

In general, tires

should be replaced after six
years regardless of tread wear.
However, heat caused by hot
climates or frequent high loading
conditions can accelerate the
aging process and may require
tires to be replaced more
frequently.

WARNING:

You should

replace your spare tire when you
