Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square
inch (psi) or kilopascals (kPa) before a tire has
built up heat from driving. SeeInation - Tire
Pressure on page 457.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.
DOT Markings:A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identication Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.
GVWR:Gross Vehicle Weight Rating.
SeeLoading Your Vehicle on page 356.
GAWR FRT:Gross Axle Weight Rating for the
front axle. SeeLoading Your Vehicle on page 356.
GAWR RR:Gross Axle Weight Rating for the
rear axle. SeeLoading Your Vehicle on page 356.

Spare Tire
Your vehicle, when new, had a fully-inated
spare tire. A spare tire may lose air over time,
so check its ination pressure regularly.
SeeInation - Tire Pressure on page 457and
Loading Your Vehicle on page 356for information
regarding proper tire ination and loading your
vehicle. For instruction on how to remove, install or
store a spare tire, seeRemoving the Flat Tire
and Installing the Spare Tire on page 479
andStoring a Flat or Spare Tire and Tools on
page 488.
After installing the spare tire on your vehicle,
you should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire and
its wheel together.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric, leather,
and plastic surfaces. Regular vacuuming is
recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes of
heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and
garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.
When cleaning your vehicle’s interior, only use
cleaners specically designed for the surfaces
being cleaned. Permanent damage may result
from using cleaners on surfaces for which they
were not intended. Use glass cleaner only on glass.
491

Remove any accidental over-spray from other
surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the rear window defogger. When cleaning
the glass on your vehicle, use only a soft cloth
and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to
all safety instructions on the label. While cleaning
your vehicle’s interior, maintain adequate
ventilation by opening your vehicle’s doors and
windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.
Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary,
you can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave
a residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such
as naptha, alcohol, etc.
