tire type FORD MUSTANG 2003 4.G Owners Manual

turn ignition OFF and restart the engine with all
other objects on the key ring held away from the
ignition key. Check to make sure thecoded keyis
an approved Fordcoded key.
If your keys are lost or stolen you will need to do
the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to a dealership or a
locksmith. The key codes will need to be erased
from your vehicle and new key codes will need to
be re-coded.
Replacing coded keys can be very costly and you
may want to store an extra programmed key away
from the vehicle in a safe place to prevent an
unforeseen inconvenience.
The correctcoded keymust be used for your
vehicle. The use of the wrong type ofcoded key
may lead to a“no start”condition.
If an unprogrammed key is used in the ignition
it will cause a“no start”condition.
Programming spare keys
A maximum of eight keys can be coded to your
vehicle. Only SecuriLock
keys can be used. To
program acoded keyyourself, you will need two
previously programmedcoded keys(keys that
already operate your vehicle’s engine) and the new
unprogrammed key(s) readily accessible for timely
implementation of each step in the procedure.
If two previously programmed coded keys are not
available, you must bring your vehicle to your
dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure
before you begin.

Ifyou use the temporary spare tire
continuously or do not follow these
precautions, the tire could fail, causing you to lose
control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tiredo not:
•use more than one temporary spare tire at a time
•exceed 80 km/h (50 mph) or drive further than 3
200 km (2 000 miles) total under any
circumstances
•load the vehicle beyond maximum vehicle load
rating listed on the tire pressure label on the
inside of the glove compartment door
•tow a trailer
•use tire chains
•drive through an automatic car wash, because of
the vehicle’s reduced ground clearance
•try to repair the temporary spare tire or remove it
from its wheel
•use the wheel for any other type of vehicle
Use of a temporary spare tire at any one wheel
location can lead to impairment of the following:
•handling, stability and braking performance
•comfort and noise
•ground clearance and parking at curbs
•Winter driving capability
Tire change procedure
To prevent the vehicle from moving when
you change a tire, be sure the parking brake
is set, then block (in both directions) the wheel
that is diagonally opposite (other side and end of
the vehicle) to the tire being changed.
Roadside Emergencies
166

•Using the air conditioner or defroster may reduce
fuel economy.
•You may want to turn off the speed control in
hilly terrain if unnecessary shifting between third
and fourth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
•Resting your foot on the brake pedal while driving
may reduce fuel economy.
•Combine errands and minimize stop-and-go
driving.
Maintenance
•Keep tires properly inflated and use only
recommended size.
•Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
•Use recommended engine oil. Refer toLubricant
specificationsin this chapter.
•Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
•Carrying unnecessary weight may reduce fuel
economy (approximately 0.4 km/L [1 mpg] is lost
for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for
example bug deflectors, rollbars/light bars,
running boards, ski/luggage racks) may reduce
fuel economy.
•Using fuel blended with alcohol may lower fuel
economy.
•Fuel economy may decrease with lower
temperatures during the first 12–16 km (8–10
miles) of driving.

INFORMATION ABOUT UNIFORM TIRE QUALITY
GRADING
New vehicles are fitted
with tires that have a
rating on them called
Tire Quality Grades.
The Quality grades can
be found where
applicable on the tire sidewall between tread
shoulder and maximum section width. For example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by
standards that the United States Department of
Transportation has set.
Tire Quality Grades apply to new pneumatic tires for
use on passenger cars. They do not apply to deep
tread, winter-type snow tires, 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 climates.

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.

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.
