4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D“ means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-tion pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment 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 climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.

Tire terminology and defini-
tions
Air Pressure
The amount of air inside the tire
pressing outward on 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 exam-
ples of optional accessories are auto-
matic transmission, 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.
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 com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the
Rear axle.

Maintenance
Radial-ply tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-ply tires used on this vehicle are of
belted construction, and are selected
to complement the ride and handling
characteristics of your vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use
the same recommended inflation
pressure. Mixing of radial-ply tires
with bias-ply or bias belted tires is
not recommended. Any combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: Identical pairs of radial-ply
tires should always be used as a set
for the front tires and a set for the
rear tires.Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
Low aspect ratio tires
Low aspect ratio tires, the aspect
ratio is lower than 50, are provided
for sporty looks.
Because low aspect ratio tires are opti-
mized for handling and braking, their
sidewall is a little stiffer than a standard
tire. Also low aspect ratio tires tend to
be wider and consequently have a
greater contact patch with the road
surface. In some instances they may
generate more road noise compared
with standard tires.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
may cause loss of vehicle con-
trol resulting in an accident.

Cleaning the upholstery andinterior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Leather (if equipped)
Feature of Seat Leather
- Leather is made from the outerskin of an animal, which goes
through a special process to be
available for use. Since it is a nat-
ural object, each part differs in
thickness or density.
Wrinkles may appear as a natural result of stretching and shrinking
depending on the temperature
and humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
products.
Using anything but recom-
mended cleaners and proce-
dures may affect the fabric’s
appearance and fire-resistant
properties.
CAUTION
Wrinkles or abrasions which
appear naturally from usage
are not covered by warranty.
Belts with metallic acces-
sories, zippers or keys inside
the back pocket may damage
the seat fabric.
Make sure not to wet the seat.
It may change the nature of
natural leather.
Jeans or clothes which could
bleach may contaminate the
surface of the seat covering
fabric.
CAUTION

Caring for the leather seats- Vacuum the seat periodically toremove dust and sand on the seat.
It will prevent abrasion or damage
of the leather and maintain its qual-
ity.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of proper leather protective may prevent abrasion of the cover
and helps maintain the color. Be
sure to read the instructions and
consult a specialist when using
leather coating or protective agent.
- Light colored (beige, cream beige) leather is easily contaminated and
the stain is noticeable. Clean the
seats frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack. Cleaning the leather seats
- Remove all contaminationsinstantly. Refer to instructions
below for removal of each contam-
inant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminate spot.
Wipe off the cream with a wet cloth
and remove water with a dry cloth.
- Beverages (coffee, soft drink, etc.) Apply a small amount of neutral
detergent and wipe until contami-
nations do not smear.
- Oil Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
- Chewing gum Harden the gum with ice and
remove gradually.Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken
the seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
