diagonal or bias ply construction; and the letter B means
belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent

Tire Terminology and De nitions
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 In ation 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. SeeIn ation - Tire Pressure on page 5-58.
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 Identi cation

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
speci cally 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. 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. 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 GM dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your GM dealer to remove
odors from your vehicle’s upholstery.
