2003 FORD MUSTANG Owners Manual

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 A
and B represent higher levels of performance on the
laboratory test wheel than the minimum required by
law.
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.

SERVICING YOUR TIRES
Checking the tire pressure
•Use an accurate tire pressure gauge.
•Check the tire pressure when tires are cold, after
the vehicle has been parked for at least one hour
or has been driven less than 5 km (3 miles).
•Adjust tire pressure to recommended
specifications found on the certification label on
the driver side door latch pillar.
Improperly inflated tires can affect vehicle
handling and can fail suddenly, possibly
resulting in loss of vehicle control.
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.

Replacing the tires
Replace the tires when
the wear band is visible
through the tire treads.
When replacing full size tires, never mix
radial bias-belted, or bias-type tires. Use
only the tire sizes that are listed on the tire
pressure decal. Make sure that all tires are the
same size, speed rating, and load-carrying capacity.
Use only the tire combinations recommended on
the label. If you do not follow these precautions,
your vehicle may not drive properly and safely.
Make sure that all replacement tires are of
the same size, type, load-carrying capacity
and tread design (e.g.,“All Terrain”, etc.), as
originally offered by Ford.
Make sure that all replacement tires are of
the same size, type, load-carrying capacity
and tread design (e.g.,“All Terrain”,“Touring”,
etc.), as originally offered by Ford.
Maintenance and Specifications
235

Failure to follow these precautions may
adversely affect the handling of the vehicle
and make it easier for the driver to lose control
and roll over.
Tires that are larger or smaller than your vehicle’s
original tires may also affect the accuracy of your
speedometer.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving
at very high speeds for extended periods of time
may result in damage to vehicle components.
Snow tires must be the same size and grade
as the tires you currently have on your
vehicle.
The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and
chains. Use chains on the tires only in an emergency
or if the law requires them.
Follow these guidelines when using snow tires and
chains:
•Chains may damage aluminum wheels.
•Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage your vehicle.
•SAE Class S chains may be used on P205/65R15
tires.
•Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
Maintenance and Specifications
236

•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
•The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.

changed unless a leak is suspected, service is
required or the axle assembly has been submerged
in water. The axle lubricant should be changed any
time the rear axle has been submerged in water. Fill

on the dipstick or on the dipstick handle. MERCON
and MERCONV are not interchangeable. DO NOT
mix MERCONand MERCONV. Refer to your
scheduled maintenance guide to determine the
correct service interval.

applications may vary based on cooler size and if
equipped with an in-tank cooler. The amount of
transmission fluid and fluid level should be set by
the indication on the dipstick’s normal operating
